NHA EKG Technician (CET) — All Questions

Before performing an EKG on an inpatient, how should the technician identify the patient?

• a.Ask the family member at the bedside to confirm who the patient is
• b.Check that the room number and bed number match the order sheet
• c.Call the patient by name and proceed if the patient answers to it
• d.Have the patient state name and birth date and check the band✓

Two patient identifiers, most commonly full name and date of birth verified against the armband and the order, are the accepted standard, and the patient states them rather than confirming a name that is read aloud. Room and bed numbers change with transfers and are never acceptable identifiers. Patients may answer to the wrong name when medicated, confused, or hard of hearing, and confirmation by a family member does not replace the two required identifiers.The Joint Commission National Patient Safety Goal 01.01.01

An EKG technician looks up the chart of a coworker who was admitted overnight, out of concern for her wellbeing. Is this permitted?

• a.Yes, because a personal friendship gives a legitimate reason to look
• b.Yes, because employees may view records at the facility that employs them
• c.No; access without a treatment or operations purpose is a violation✓
• d.Yes, as long as the technician does not repeat what she reads

Federal privacy rules limit access to protected health information to what a person needs for their own job duties, so browsing a coworker's chart out of curiosity or concern is a reportable violation regardless of intent. Employment grants access only to the records needed for assigned work, not to the whole system. Keeping the information secret afterward does not cure the improper access, and a personal relationship is not a permitted purpose.HIPAA

Two technicians are discussing a patient's abnormal EKG in a crowded elevator. What is the problem?

• a.It is a problem only if a member of the patient's family is present
• b.Nothing, as long as they avoid using the patient's first and last name
• c.Nothing is wrong, because both of them work for the same facility
• d.Protected health information can be overheard by unauthorized people✓

Discussing a patient where visitors and unrelated staff can overhear is an improper disclosure of protected health information, and clinical conversations belong in private areas. Omitting the name does not protect a patient who is still identifiable from the room, the diagnosis, or the context. Being coworkers permits discussion only when there is a treatment need and a private setting, and the violation exists whether or not a relative happens to be in the elevator.HIPAA

When must an EKG technician perform hand hygiene?

• a.Before and after every patient contact and after glove removal✓
• b.Only after contact with blood or other potentially infectious fluid
• c.Only at the beginning and at the end of each scheduled work shift
• d.Only when the hands look or feel visibly soiled during the shift

Hand hygiene is required before and after every patient contact, after glove removal, and after touching potentially contaminated surfaces or equipment, because gloves can have unseen defects and hands become contaminated during removal. Waiting for a blood or fluid exposure ignores the routine transfer of organisms from intact skin and from equipment. Visible soil is a reason to wash but not the threshold for washing, and shift-based washing leaves every patient in between unprotected.CDC Guideline for Hand Hygiene in Health-Care Settings

A patient's chest has an open, draining wound near a chest electrode site. What does the bloodborne pathogens standard require of the technician?

• a.No special measures are needed, because an EKG is a noninvasive test
• b.Apply the electrode directly over the wound to keep placement accurate
• c.Postpone the test and send the patient home until the wound has healed
• d.Treat the drainage as infectious and keep electrodes off the site✓

The bloodborne pathogens standard requires that all blood and other potentially infectious material be treated as infectious, so gloves and any other indicated protective equipment are worn and contaminated items are disposed of properly. Electrodes are not applied over broken or draining skin; the site is shifted slightly and the change is documented. A noninvasive test does not exempt the technician from precautions, and postponing an ordered test because of a wound withholds care that can be given safely.OSHA 29 CFR 1910.1030

A patient asks the EKG technician, "Does this tracing mean I had a heart attack?" What is the appropriate response?

• a.Explain that the physician reads the tracing, and tell the nurse✓
• b.Hand the tracing to the patient so that he can read it for himself
• c.Reassure the patient that the tracing looks completely normal to you
• d.Tell the patient that the tracing looks like a heart attack to you

Interpreting and diagnosing are outside the EKG technician's scope of practice, so the appropriate response refers the question to the provider, acknowledges the patient's concern, and passes the question along to the nurse. Offering a reassuring reading is as far outside scope as offering an alarming one, and either may turn out to be wrong. Releasing the tracing directly to the patient bypasses both the provider and the facility's record release process.

While attaching electrodes, the technician sees ventricular fibrillation appear on the screen and the patient becomes unresponsive. What is the first action?

• a.Document the time and the rhythm in the patient's medical record
• b.Finish the 12-lead tracing so the physician has a complete record
• c.Call for help, activate the emergency response, and start CPR✓
• d.Reposition the electrodes first to rule out a movement artifact

Ventricular fibrillation in an unresponsive patient is a cardiac arrest, and survival depends on immediate activation of the emergency response followed by prompt CPR and defibrillation. Checking for artifact is the right instinct in the wrong patient: it applies when the person is awake and stable, and this patient is not. Completing the tracing or documenting first spends the minutes that determine the outcome.

During a treadmill stress test, the patient reports chest pain and the monitor shows new ST segment depression. What should the technician do?

• a.Tell the patient that chest discomfort is expected and continue the stage
• b.Stop the test, notify the supervising provider, and keep monitoring✓
• c.Turn the monitor away so that the patient does not become anxious
• d.Increase the treadmill speed to finish the protocol stage

New chest pain or significant ST changes are recognized indications to terminate a stress test, and the supervising provider is notified at once while the patient continues to be monitored through recovery. Advancing the protocol raises myocardial oxygen demand at exactly the moment the heart is showing it cannot meet demand. Dismissing the symptom is unsafe, and turning the monitor away removes the information needed to manage the event.

Which information must appear on every EKG tracing?

• a.The technician's home phone number and the machine's serial number only
• b.The patient's next scheduled appointment date and the clinic's location
• c.The patient's admitting diagnosis and the name of the insurance carrier
• d.The patient's name and identifier, the date and time, and who took it✓

A tracing is a legal part of the medical record and must identify the patient, the exact date and time it was taken, and the person who took it, along with any deviation such as altered electrode placement or a non-standard setting. Diagnoses are supplied by the interpreting physician rather than the technician. Insurance and appointment details belong elsewhere in the record, and personal contact information for staff is never placed on a tracing.

What is appropriate routine maintenance for EKG equipment between patients?

• a.Clean the machine only when it looks visibly soiled or sticky
• b.Wipe the machine and cables with an approved disinfectant✓
• c.Wrap the lead wires tightly around the machine to save space
• d.Submerge the entire patient cable in a disinfectant solution

Between patients the machine surfaces, cables, and any reusable components are wiped with a facility-approved disinfectant, the wires are inspected for cracks and gently uncoiled, and supplies are restocked so the unit is ready for the next study. Immersing a patient cable ruins the connectors and creates an electrical hazard. Wrapping wires tightly breaks the internal conductors and causes artifact, and waiting for visible soil ignores contamination that cannot be seen.

A patient is being fitted with a 24-hour Holter monitor. Which instruction is correct?

• a.Keep a diary of activities and symptoms with the times they occur✓
• b.Avoid all physical activity so that the recording stays clean
• c.Take the monitor off for showers and write down the time
• d.Remove the electrodes at bedtime and reapply them the next morning

The value of a Holter study comes from matching recorded rhythm changes to the patient's diary of activities and symptoms, so accurate timed entries are essential, and the recorder stays on and dry for the whole recording period. Removing electrodes for a shower or overnight creates gaps in exactly the hours the study is trying to capture. Patients are told to follow their usual routine rather than to rest, because the point is to record everyday events.

What is the purpose of telemetry monitoring?

• a.It records the patient's heart sounds for a physician to review later
• b.It records a permanent 12-lead tracing once during every shift
• c.It sends the rhythm continuously to a central monitoring station✓
• d.It measures the blood pressure automatically every fifteen minutes

Telemetry uses a small battery-powered transmitter worn by the patient to send the cardiac rhythm wirelessly to a central station, allowing continuous observation while the patient moves about the unit. A 12-lead EKG is a separate diagnostic study recorded on a stationary machine, not something telemetry produces. Automated blood pressure monitoring and heart sound recording use entirely different equipment.

Which instructions should a patient receive before a scheduled exercise stress test?

• a.Stop taking all prescription medications for one week before the test
• b.Avoid food, caffeine, and tobacco as directed; wear walking shoes✓
• c.Wear dress shoes and take all usual medications without mentioning them
• d.Eat a large meal beforehand and drink strong coffee for extra energy

Standard stress test preparation includes fasting and avoiding caffeine and tobacco for the period the facility specifies, wearing comfortable two-piece clothing and supportive walking shoes, and reviewing current medications with the provider, since drugs such as beta blockers blunt the heart rate response. Patients do not stop medications on their own; that decision belongs to the ordering provider and stopping some drugs abruptly is dangerous. Eating heavily or drinking coffee alters the result, and dress shoes are unsafe on a treadmill.

An anxious patient is trembling and asks whether the EKG will shock her. What is the best response?

• a.Explain simply that the machine records and delivers no current✓
• b.Explain the electrical engineering of the machine in full technical detail
• c.Have her sign the consent form and then start the test without discussion
• d.Tell her there is nothing at all to worry about and start attaching leads

A clear, simple explanation lowers anxiety, and a relaxed patient also produces a tracing free of somatic tremor artifact, so communication here is both a professional and a technical necessity. Dismissing the concern leaves the patient frightened and tense, which shows up in the tracing. An overly technical explanation confuses rather than reassures, and collecting a signature without answering the question is not informed cooperation.

A competent adult patient refuses to allow an ordered EKG. What should the technician do?

• a.Tell the patient that he will be billed for the refused test
• b.Stop, respect the refusal, and notify the nurse or provider✓
• c.Perform the test anyway, because the physician has ordered it
• d.Have a family member give permission instead

A competent adult has the right to refuse any procedure, and proceeding without consent could constitute battery, so the technician stops, reports the refusal to the nurse or ordering provider, and documents what happened. A physician order authorizes the test but does not override the patient's decision. Threatening the patient with a charge is coercion, and a family member cannot consent on behalf of a competent adult.

A technician sustains a needlestick-free but bloody scratch from a broken bed rail while positioning a patient. What is the required response?

• a.Finish the EKG and mention it to someone at the end of the shift
• b.Document the incident in the patient's chart and then keep working
• c.Wash the area and report the exposure to the supervisor at once✓
• d.Cover it with a glove and continue with the rest of the patients

The bloodborne pathogens standard requires that an exposure incident be washed immediately and reported without delay, so the employer can provide a confidential medical evaluation and any indicated post-exposure follow-up, which is time-sensitive and loses effectiveness with every hour. Waiting until the shift ends can forfeit that protection. Covering the wound and continuing risks both the technician and the patients, and an employee exposure is recorded in an incident report rather than in the patient's chart.OSHA 29 CFR 1910.1030

A technician notices she wrote the wrong date on a completed paper EKG record. How should the correction be made?

• a.Shred the record and print a new one without noting that it changed
• b.Erase the wrong entry neatly and then write the correct date over it
• c.Draw a single line through the error, correct it, and initial it✓
• d.Cover the error with correction fluid and write the new date over it

A legal health record is corrected by drawing one line through the error so it stays readable, entering the correct information, and initialing and dating the change, which preserves an honest audit trail. Erasing or covering the entry destroys the original and looks like concealment even when the intent is innocent. Destroying a record and silently replacing it is falsification of a medical record.

An outpatient's routine 12-lead shows a run of ventricular tachycardia, but the patient feels fine and asks to leave. What should the technician do?

• a.Keep the patient in the department and notify the provider at once✓
• b.Repeat the tracing until a normal one prints, then release him
• c.Give the patient the tracing to take to his next appointment
• d.Reassure the patient, let him leave, and file the tracing

A critical finding such as a run of ventricular tachycardia is reported to the provider immediately and the patient is kept under observation, because a patient who feels well can deteriorate without warning. Filing the tracing for later review delays urgent care by hours or days. Repeating the study until it looks normal conceals a real finding, and handing the tracing to the patient moves a clinical responsibility onto someone who cannot act on it.

Which action best reflects professional behavior for an EKG technician?

• a.Introduce herself by name and title and work within her scope✓
• b.Perform a lab draw because the unit is short staffed tonight
• c.Post an interesting anonymized rhythm strip on social media
• d.Tell the patient's spouse the results while the patient is away

Professionalism means identifying yourself and your role, explaining what you are about to do, and working strictly within your training and scope of practice. Posting strips online risks re-identification and violates patient privacy even when names are removed. Sharing results with a spouse without authorization is an improper disclosure, and performing an untrained procedure exceeds scope no matter how short staffed the unit is.

A billing clerk asks an EKG technician to send a patient's entire inpatient chart so that a claim for one 12-lead can be processed. Applying the HIPAA minimum necessary standard, what should the technician do?

• a.Send the whole chart, because billing staff are workforce members with access
• b.Send nothing until the patient signs an authorization in writing
• c.Release only the order, the tracing, and the data needed to bill it✓
• d.Refuse the request, because billing disclosures need a court order

The minimum necessary standard limits any use or disclosure to the information actually needed for the purpose at hand, and billing one 12-lead needs the order, the tracing, and the demographic and coverage data rather than the full chart. Disclosures for payment are permitted without a signed authorization, so waiting for the patient's signature would stall a legitimate claim, and no court order is involved in routine billing. Being a workforce member does not entitle a clerk to everything in a record; access is limited by role and by purpose. The recognized exception to minimum necessary is a disclosure to another provider for treatment, which this request is not.

A technician steps away from the EKG cart to fetch a stretcher and leaves a completed tracing with the patient's name displayed on the cart screen in a hallway. What is the correct assessment of this situation?

• a.It is acceptable because the hallway lies inside a restricted clinical unit
• b.Leaving readable patient data unattended defeats the required safeguards✓
• c.It is a concern only if someone without access reads the screen
• d.It falls outside privacy rules because the tracing was not yet printed

Patient data displayed on an unattended screen is protected health information sitting in the open, and the safeguard requirements cover workstation and device security regardless of whether anyone is caught reading it. The screen should be cleared or locked, or the cart kept attended. A restricted unit still has visitors, transport staff, and other patients moving through it, so the location does not remove the exposure. Waiting for proof that someone read the display makes the safeguard meaningless, and an on-screen tracing is patient data whether or not paper has come out of the machine.

A patient's adult son stops the technician in the corridor and asks how his mother's EKG turned out. The mother has not agreed to have her information shared with him. What should the technician do?

• a.Give him a general summary, since immediate family may receive results
• b.Answer once he produces identification showing that he is her son
• c.Explain that results come from her provider and direct him there✓
• d.Tell him only whether the tracing was normal or abnormal today

Two separate rules point the same way here: the technician does not interpret a tracing for anyone, and the mother has not agreed to sharing, so the son is directed to the provider who ordered the study. Being immediate family creates no automatic right to a result; disclosure to a relative involved in care depends on the patient's agreement or, when she is unavailable, on professional judgment by the treating staff. Identification proves who a person is, not that the patient wants him told. Saying only whether the tracing was normal or abnormal is still both a disclosure and an interpretation.

Midway through acquiring a 12-lead, a patient says she has changed her mind and wants the technician to stop. The electrodes are still attached and the recording is not complete. What should the technician do?

• a.Finish the few remaining seconds, because stopping now wastes the study
• b.Explain that the consent she gave at the start covers the whole procedure
• c.Notify the supervisor before continuing so the order is not left undone
• d.Stop at once, remove the electrodes, and document that consent was withdrawn✓

Consent may be withdrawn at any point, and continuing to touch a patient who has told the technician to stop is battery no matter how little of the tracing remains. The correct sequence is to stop, remove the electrodes, tell the patient what happens next, and document the withdrawal and the notification of the ordering provider. Treating the initial agreement as covering the rest of the procedure misstates how consent works. Escalating the question first is wrong here because it leaves the technician working on a patient who has already refused; the stopping cannot wait for anyone else's decision.

A charge nurse asks an EKG technician to pull a patient's femoral sheath after a cardiac catheterization, a task the technician has had no training in performing. What should the technician do?

• a.Carry out the task, because a licensed nurse has delegated it
• b.Carry out the task while the nurse watches and corrects any error
• c.Read the facility procedure and attempt the removal once carefully
• d.Decline, state that the task is outside her training, and tell the supervisor✓

A delegated task is accepted only when it falls within the technician's scope and the technician is trained and competent to perform it; delegation by a licensed person does not transfer competence. Declining and routing the request through the supervisor gets the patient a qualified caregiver and puts the staffing gap where it can be fixed. Performing an untrained invasive task under observation is still performing it, and a bleeding femoral site leaves no time to correct an error. Reading a written procedure is not training, and a first attempt learned from a manual is exactly the conduct that falls below the standard of care.

While placing chest electrodes on an older adult outpatient, a technician sees patterned bruises in several stages of healing, and the relative who brought her answers every question directed to the patient. What should the technician do?

• a.Ask the relative how the bruises happened before recording it in the chart
• b.Chart nothing about the bruises, since a technician cannot substantiate abuse
• c.Photograph the bruises with the department camera for the record
• d.Document the objective findings and report the concern to the supervisor✓

Health care workers in most states are mandated reporters of suspected abuse of an older adult, and the threshold is reasonable suspicion, not proof. Recording exactly what was seen, in neutral descriptive terms, and routing the concern up the chain of command starts the process the facility and the state require. Questioning the accompanying relative can alert a possible abuser and put the patient at greater risk. Declining to chart the finding destroys the only contemporaneous record of it, and photographs of injuries are taken only under a specific facility or forensic protocol, not by a technician on her own initiative.

A technician posts an image of an unusual rhythm strip to a closed social media group for cardiac technicians, having cropped away the name field and the date. What is the problem with the post?

• a.There is no problem, because the identifiers were cropped out of the image
• b.The post is acceptable only if the group is limited to health care workers
• c.The tracing is still patient information, and posting it discloses it without authorization✓
• d.The post becomes a violation only when a member of the group recognizes the patient

A tracing is information created about an identifiable individual, and cropping the visible name field does not by itself de-identify it, because the date, the device, the setting, and the clinical detail can still point back to one person. Sharing it outside the facility for a purpose other than treatment, payment, or operations requires the patient's written authorization. A closed group is still an audience with no treatment relationship to the patient, so limiting membership to clinicians does not create permission. Waiting until someone recognizes the patient misstates the rule, since the disclosure is complete at the moment of posting.

An EKG technician notices that a coworker on the same shift smells of alcohol and is slurring words while connecting a patient's lead wires. What should the technician do?

• a.Report the observation to the supervisor now✓
• b.Wait until the shift ends and ask the coworker
• c.Finish the tracing and speak with him privately
• d.Note the concern in the patient's chart instead

An apparently impaired coworker is an immediate patient-safety problem, and every facility routes that concern up the chain of command at once so the coworker can be removed from patient care and evaluated. Waiting until the end of the shift leaves an impaired worker on patients for hours. A private conversation is a reasonable instinct for a minor performance issue but not for suspected impairment, where the technician has no way to assess fitness and no authority to remove anyone from duty. The patient's chart is a record of that patient's care, so a note about staff conduct does not belong in it.

A staff nurse looks at a tracing the technician has just acquired and asks whether it looks like a heart block. What is the appropriate response for the technician?

• a.Offer an opinion, since a nurse and not the patient is asking the question
• b.State that the machine's printed interpretation is the official reading
• c.Decline to comment and say nothing further about the tracing
• d.Describe what was observed and note that a provider must interpret it✓

Reporting objective observations is part of the technician's job: the measured rate, whether the rhythm is regular, and what the machine printed are all facts that can be handed to the nurse. Attaching a diagnosis to them is not, whoever is asking, because interpretation belongs to the physician or other qualified provider. The computer statement on the printout is explicitly unconfirmed until a physician reads and signs the tracing, so calling it official is wrong and can propagate an error. Refusing to say anything at all overcorrects and withholds information the nurse legitimately needs to prioritize care.

An outpatient asks the technician for a copy of the tracing that was just recorded, saying she wants it for a second opinion elsewhere. What should the technician do?

• a.Explain that patients receive the physician's report rather than raw tracings
• b.Tell her she has a right of access and send her to health information management✓
• c.Print a second copy and hand it to her after checking her wristband
• d.Ask the supervisor to release the tracing at the end of the visit

A patient has a right of access to her own designated record set, and the tracing is part of it, so the answer is not refusal but referral to the department that verifies identity, logs the request, and releases the record within the required time. Telling her that only the physician's report may be released misstates that right. Handing over a copy at the machine skips the verification and the accounting that the records process exists to provide, even though the wristband was checked. Routing the request to the supervisor is unnecessary and simply delays a request the records department handles as a matter of routine.

A nurse asks an EKG technician to run a 12-lead on an alert, stable patient because the patient looks unwell, but no order for the tracing has been entered. What should the technician do?

• a.Perform the tracing, since a nurse's verbal request functions as an order
• b.Perform the tracing and have the order entered into the chart afterward
• c.Explain that an order is required and notify the supervisor of the nurse's concern✓
• d.Refuse and tell the nurse to have the provider come to the bedside first

A diagnostic test is performed on a provider's order, and a technician working without one has acted outside the scope of the job and left the study unbillable and unowned. Explaining the requirement and passing the clinical concern up the chain gets the order entered quickly while keeping the patient's deterioration visible to someone who can act on it. Treating a nurse's request as an order confuses a request with authorization; a nurse may take a verbal order from a provider, but the technician has no such order here. Performing the tracing and back-filling the order documents an event that did not happen in the sequence charted. Simply refusing and walking away drops a stated clinical concern about a patient.

A scheduled outpatient walks into the EKG room, sits down, and begins unbuttoning her shirt as the technician explains the test. Which form of consent does her behavior represent?

• a.Informed consent, because the procedure was explained first
• b.Implied consent, shown by her cooperation✓
• c.Written consent, satisfied by the registration paperwork
• d.Expressed consent, given when she booked the appointment

Consent inferred from a patient's cooperative conduct is implied consent, and it is what a routine noninvasive 12-lead relies on. Informed consent is a documented discussion of risks, benefits, and alternatives conducted by the provider performing an invasive or higher-risk procedure, so explaining the steps of a tracing does not convert this into informed consent. General registration paperwork is a consent to treat and is not the specific written consent form used for a procedure. Expressed consent is a spoken or written statement of agreement, and booking an appointment is not that statement.

A technician discovers that a comment she entered in the electronic record an hour earlier lists the wrong room number. How should the entry be corrected?

• a.Delete the entry from the record and re-enter the information correctly
• b.Ask the supervisor to have the records office remove it
• c.Use the amendment function so the original entry remains visible✓
• d.Leave the entry and note the mistake in the next shift note

An electronic record is corrected through the system's amendment or addendum function, which stores the new text alongside the original and stamps who changed what and when. Deleting the entry destroys part of a legal record and shows up in the audit trail as exactly that. Routing a routine self-caught error to the records office through the supervisor is neither necessary nor how correction rights work, since the author corrects her own entry. Leaving the error uncorrected and mentioning it elsewhere leaves the wrong information in the place where the next reader will look.

An employer telephones the clinic and asks for the result of a pre-employment EKG that one of its applicants completed there. What is required before the result may be released?

• a.The general consent to treat that the patient signed at registration
• b.A verbal agreement from the patient documented in the record
• c.Nothing, because the employer paid for the test
• d.A signed HIPAA authorization that names the employer✓

Releasing results to an employer is a disclosure outside treatment, payment, and health care operations, so it requires the patient's signed authorization identifying who may receive the information and what may be sent. A consent to treat permits care to be given; it does not permit disclosure to an outside party. A verbal agreement noted in the chart does not meet the written-authorization requirement, however well documented. Paying for a test buys the service, not the result, and the fact that the employer arranged and funded the examination gives it no independent right of access.

After a busy morning a technician realizes that a tracing she recorded an hour ago was saved under a different patient's name, and the record has already gone to the reading physician. What should the technician do?

• a.Report the error to the supervisor at once✓
• b.Wait and see whether the physician catches it
• c.Correct the name in the system and say nothing
• d.Note it on both charts at the end of the shift

A tracing filed under the wrong name puts one patient's data in front of a physician who will act on it for someone else, which is both a misidentification event and a disclosure, so it is escalated immediately rather than handled quietly. Prompt reporting lets the department pull the record from the reading queue before an interpretation is signed. Waiting for the physician to notice leaves a wrong result in an active chart. Fixing the name without telling anyone hides an event the facility has to track and may leave the mistaken interpretation in place, and holding the correction until the end of the shift gives the error hours to travel.

A patient's forearm is scraped by the EKG cart during transport, and an incident report is completed. What is the correct handling of that report?

• a.It is filed separately from the medical record✓
• b.It substitutes for charting the injury in the record
• c.It is scanned into the patient's chart as an addendum
• d.It is released to the patient with her other records

An incident report is an internal risk-management document, kept outside the medical record and outside what is released to the patient, which is why the chart must separately document the injury, the assessment, and the care given. Filing the report in the chart, or even referencing it there, can pull it into the released record and defeat the protection it carries in many states. Treating the report as a substitute for charting leaves the patient's own record silent about an injury that happened during care. The report is likewise not part of the designated record set a patient may request.

A technician forgets to chart a tracing performed at the end of her shift and returns the next morning to document it. What is the correct way to make that entry?

• a.Label it a late entry with the time of the tracing and of the entry✓
• b.Insert the note into the blank space left in the previous day's charting
• c.Chart it with the current date and time and no further comment
• d.Have the coworker now on duty enter it so the timing looks right

Documentation made after the fact is charted as a late entry, identified as such, carrying the date and time the care was actually delivered as well as the date and time of the entry. Writing it into blank space in the prior day's notes makes the record appear contemporaneous when it is not, which is falsification. Charting it under the current time alone puts the tracing on the wrong day and misrepresents the sequence of care. Asking another person to record work she did not perform is charting for someone else, which no facility permits.

A patient scheduled for a 12-lead speaks only Mandarin, and her teenage daughter offers to translate the technician's instructions. What should the technician do?

• a.Use the facility's qualified medical interpreter rather than the daughter✓
• b.Accept the daughter's help, because she knows her mother's history
• c.Ask the supervisor to move the tracing to an interpreter day
• d.Use gestures to demonstrate each step and proceed without help

Facilities receiving federal funds must provide language assistance at no cost to the patient, and qualified interpreters, including telephone and video services, exist for exactly this situation. Using a family member, particularly a minor, risks omitted or softened information and hands a child responsibility for a parent's medical communication. Rescheduling denies a patient timely care that an interpreter line could support within minutes. Gesturing through the procedure leaves the patient unable to ask a question, report discomfort, or meaningfully agree to what is being done.

A patient with moderate dementia becomes agitated and pushes the technician's hand away when chest electrode placement begins. Which approach is most appropriate?

• a.Work faster so the tracing is finished before the agitation increases
• b.Ask a family member to hold her arms still during the recording
• c.Explain each of the ten electrode positions in careful detail
• d.Approach calmly, use short simple sentences, and repeat them as needed✓

A patient with dementia processes speech slowly and reacts to tone and pace, so a calm approach, brief concrete sentences, one instruction at a time, and patient repetition are what allow the tracing to be obtained. Speeding up increases the agitation the technician is trying to avoid and raises the odds of motion artifact and a repeated study. Having a relative restrain her arms is physical restraint applied without an order and is not an acceptable way to complete a routine test. A detailed anatomical explanation adds information the patient cannot hold and tends to deepen the confusion.

A patient appears embarrassed when told that her chest must be exposed for the precordial leads. Which action best respects her modesty without compromising the tracing?

• a.Drape a gown or sheet over the chest between electrode placements✓
• b.Place the chest electrodes over the gown to avoid uncovering her
• c.Record the tracing with the curtain open so that a witness can observe
• d.Omit the two chest leads that call for the greatest exposure

Exposing only the small area being worked on and re-covering it as each electrode is placed protects modesty while still giving the skin contact the tracing depends on. Electrodes applied over clothing do not conduct and produce an unusable recording. Privacy is preserved by closing the curtain or door and limiting who is in the room, so recording in the open for the sake of a witness trades one problem for another; a chaperone can be present behind a closed curtain. Leaving out chest leads yields an incomplete study, and the missing leads are the ones that show the lateral wall.

A technician is about to record a routine 12-lead on a patient whose skin is intact, who has no drainage, and who is on no isolation precautions. Which statement describes correct glove use under standard precautions?

• a.Gloves are a matter of judgment for this contact, but hand hygiene before and after is not✓
• b.Gloves are worn for the entire study, and hand hygiene may be deferred while they are in place
• c.Gloves are put on only after the electrodes are placed and the lead wires have been attached
• d.Gloves are indicated here only if the chart documents a diagnosed bloodborne infection

Standard precautions call for gloves whenever contact with blood, body fluids, mucous membranes, or non-intact skin is anticipated. Placing electrodes on clean, intact skin does not meet that trigger, so glove use follows judgment and facility policy, while hand hygiene before and after every patient contact is required regardless. Gloves are not a substitute for hand hygiene, because hands can be contaminated through unseen defects and during removal. Waiting for a documented infection misreads standard precautions, which treat every patient's blood and body fluids as potentially infectious, and delaying gloves until after the leads are on would place them on after the contaminating contact has already happened.

A patient on contact precautions for Clostridioides difficile needs a bedside 12-lead. How should the technician handle equipment and hand hygiene for this study?

• a.Wear a gown and gloves, and use an alcohol-based hand rub after removing them as in other isolation rooms
• b.Leave the machine out in the corridor and run the lead wires in through the doorway to the bedside
• c.Bring the usual cart in, wear gloves, and then wipe the lead wires with an alcohol pad on the way out
• d.Take in only what is needed, use single-patient-use electrodes, wipe the machine with a bleach wipe, and wash with soap and water✓

C. difficile forms spores that alcohol does not kill and that alcohol-based rubs do not remove well, so hands are washed with soap and water and surfaces are wiped with an EPA-registered sporicidal product such as the facility's bleach wipe. Gown and gloves are correct for contact precautions, which is why the alcohol-rub answer is the tempting one, but the hand hygiene agent and the disinfectant are what change for spores. Carrying only necessary items into the room and using single-patient-use electrodes limits what has to be disinfected afterward. Running lead wires through a doorway does not keep the wires clean and breaks the containment the precautions exist to maintain.

A patient arriving for a treadmill stress test tells the technician that he has had chest pressure since early that morning and that it has not gone away. What should the technician do?

• a.Begin at the lowest workload and stop the treadmill if the pressure gets any worse during the first stage
• b.Hold the test, report the ongoing chest pressure to the supervisor and the covering clinician, and let them decide whether it proceeds✓
• c.Record a resting 12-lead, let the patient sit quietly, and start the protocol once the pressure has eased
• d.Note the reported pressure on the test worksheet and continue with the usual skin preparation

Chest pressure that is present at rest and ongoing raises the question of an acute coronary syndrome, which is a contraindication to exercise testing until a clinician has evaluated it. The technician does not diagnose the pain and does not decide whether the study is safe, so the finding goes to the supervising physician or nurse before anything else happens. Starting at a low workload still exercises a patient whose symptoms may reflect unstable ischemia. Waiting for the pressure to ease or simply writing it on the worksheet leaves the decision with the person least qualified to make it.

While a patient is connected to a portable EKG machine, the technician feels a faint tingle on touching the machine's metal frame. What is the correct response?

• a.Stop the study, unplug the machine, and tell the supervisor about the tingle✓
• b.Finish the tracing quickly, then set the machine on a rubber mat before the next study
• c.Unplug the machine, finish the recording on battery power, and then return it to storage
• d.Keep recording without touching the frame and enter the tingle in the equipment log at shift end

A tingle from a chassis means current is leaking to surfaces that should be at ground potential, which points to a failed ground or damaged insulation. A patient wired to that machine is in the current path and cannot pull away, so the study stops, the machine comes off the line, and it is reported so biomedical engineering can test it. Switching to battery power may remove the mains fault path, but it keeps a machine with a known defect wired to a patient and then puts it back on the shelf untested, and a rubber mat under the machine does nothing about the chassis the technician is touching. Logging the problem at the end of the shift leaves a defective machine available for the next patient.

A patient stands up from the table after a 12-lead, says the room is spinning, and begins to sag toward the floor. What should the technician do first?

• a.Hold the patient upright under both arms and walk her the few steps back to the exam table
• b.Step out of the room to bring a wheelchair and a second staff member to lift the patient back onto the table
• c.Guide the patient down to the floor, protecting the head, and call out for help without leaving her✓
• d.Seat the patient in the nearest chair and notify the supervisor before anything else

A patient who is already going down cannot be held up by one person; guiding the fall to the floor while protecting the head converts an uncontrolled fall into a controlled one and protects the technician's back at the same time. Once she is down and flat, help can be summoned without leaving her unattended. Trying to walk a fainting adult back to the table risks a heavier fall and an injury to both people. Leaving the room for a wheelchair, or moving her to a chair and going to find someone, both abandon an unsteady patient at the moment she is most likely to strike her head.

A technician who has not been fit-tested for an N95 respirator is sent to record a 12-lead on a patient in an airborne infection isolation room. What should the technician do?

• a.Stay out of the room and tell the supervisor so a fit-tested technician can do the study✓
• b.Enter wearing a surgical mask and a gown, since the recording itself takes only a few minutes
• c.Take any N95 from the supply cart and hold it firmly against the face during the recording
• d.Ask the nurse whether the patient can be brought to the hallway for the tracing

Respiratory protection requires a medical evaluation, training, and fit testing before a worker wears an N95, because an unfitted respirator leaks around the seal and gives false confidence. A technician who has not been fit-tested does not enter an airborne isolation room, and the study is reassigned to someone who has been. A surgical mask is not a respirator and does not filter fine airborne particles. Pressing an untested N95 to the face does not produce a seal, and moving the patient out of a negative-pressure room to avoid the problem exposes everyone in the corridor.

During a code, the defibrillator operator calls for everyone to clear the bed immediately before the shock is delivered. What is the reason for clearing at that moment?

• a.Movement at the bedside creates artifact that keeps the defibrillator from analyzing the rhythm
• b.Contact with the patient drains energy so that less of it reaches the heart muscle
• c.Standing back keeps staff from being splashed by the conductive gel used on the pads
• d.Current would travel through anyone in contact with the patient or the bed frame✓

The shock is a current that follows every available conductive path, so a hand on the patient, on the bed rail, or on a wet sheet puts a rescuer in that path and can produce a serious shock. Artifact from movement is a real problem, but that is why the operator calls a clear during the analysis pause on an automated device, not at the instant of discharge. Energy loss to a bystander is not the concern being managed by the clear command, and gel splash is not a hazard that would justify stopping compressions. The clear is called, the operator looks at the patient and the bed, and only then is the shock delivered.

A monitored patient has a temporary transvenous pacing wire and a central venous catheter in place. Why does this patient need extra electrical precautions?

• a.Metal pacing wires pick up interference that can make the displayed rhythm resemble ventricular fibrillation
• b.Fluid inside the central catheter conducts leakage current from the bedside outlets back into the monitor
• c.A pacing wire raises the energy a defibrillator must deliver before the shock reaches the heart muscle
• d.A conductor touching the heart lets tiny leakage currents bypass the skin and reach the myocardium✓

Intact skin has high resistance and spreads current over a wide area, which is why a person can touch a small leakage current and feel nothing. A pacing wire or a fluid-filled catheter that ends at or near the heart removes that protection, so a current far below the level anyone could feel can concentrate on the myocardium and provoke fibrillation. This is the microshock hazard, and it is why exposed wire ends are insulated and handled with gloves. Interference can indeed mimic fibrillation on a display, but that is an artifact problem rather than a reason for electrical precautions, and neither the catheter fluid nor the pacing wire changes the energy a defibrillator must deliver.

The power cord of an EKG machine ends in a three-prong plug. What does the third prong accomplish?

• a.It routes excess current away from the patient cable and into the machine's internal filtering circuits
• b.It bonds the chassis to ground so fault current returns there rather than through a person✓
• c.It supplies the additional voltage the recorder and the thermal print head draw during a tracing
• d.It keeps the plug from working loose from the outlet during a bedside study

The third prong is the equipment grounding conductor. It ties the metal chassis to earth ground, so if a hot conductor contacts the frame the fault current flows harmlessly to ground and trips the breaker instead of passing through whoever touches the machine. It carries no current in normal operation and supplies no voltage to the recorder or the print head, both of which run from the two current-carrying conductors. It also has no mechanical role in retaining the plug, which is why an adapter that defeats the ground pin is a real hazard rather than a convenience.

A patient completed a 24-hour Holter and her diary records no symptoms, because the palpitations she is being investigated for happen roughly once a week. Which statement about the next step is accurate?

• a.Another 24-hour Holter is simply repeated the following week, since this recorder captured no symptoms
• b.The physician may order a patient-activated event or loop recorder worn for weeks to catch symptoms days apart✓
• c.The study is reported as a normal result, because no symptoms occurred while the recorder was worn
• d.The technician reports the failed recording to the supervisor and rebooks the patient for a repeat study

A 24-hour Holter samples a single day, so a symptom that appears about once a week is unlikely to fall inside the recording window. Longer patient-activated event monitors and loop recorders are worn or implanted for weeks precisely to capture infrequent events, and selecting that study is the ordering physician's decision. Repeating another 24-hour recording has the same low yield as the first. The recorder did not fail and nothing needs to be escalated as an equipment problem, and an absence of captured symptoms is not the same finding as a normal heart rhythm.

A patient is being fitted with an ambulatory monitor that will be worn continuously for several days. How should each electrode site be prepared?

• a.Wipe each site with alcohol and apply the electrode while the skin is still damp, for better contact
• b.Apply a thin layer of skin lotion first so that the adhesive stays comfortable over several days of wear
• c.Omit preparation and tell the supervisor that some artifact is expected here
• d.Clip hair at the site, abrade the skin lightly, and let it dry before applying a fresh electrode✓

Skin preparation is what makes a multi-day recording readable: clipping rather than shaving avoids nicks that can become infected, light abrasion removes the dead outer cells that carry most of the skin's resistance, and a dry, oil-free surface lets the adhesive hold for days. Applying an electrode to skin still wet with alcohol traps solvent under the gel and loosens the adhesive as it evaporates. Lotion is the opposite of what is wanted, since it leaves an oily film that defeats both the adhesive and the electrical contact. Skipping preparation guarantees baseline wander and lost hours of data on a study the patient cannot easily repeat.

During the second stage of a treadmill stress test, the patient's systolic blood pressure has fallen about 15 mmHg below the resting value even though the workload has increased. What should the technician do?

• a.Repeat the blood pressure at the next stage and continue the protocol if that reading is higher
• b.Stop the test, notify the supervisor and the covering clinician at once, and keep monitoring rhythm and pressure in recovery✓
• c.Slow the treadmill to a walking pace for two minutes and then resume the protocol from that stage
• d.Continue the stage as ordered, because systolic pressure normally falls as the exercise workload rises

Systolic pressure is expected to rise as workload rises. A fall below the resting value during increasing exercise suggests the heart cannot raise its output against the demand and is a recognized indication to terminate the test, so the treadmill stops and the supervising clinician is told immediately rather than at the end. Monitoring continues into recovery, because rhythm changes and ischemic changes often appear after exercise stops. Waiting for the next stage, or slowing the belt and then resuming, keeps a patient exercising through the very finding that says to stop.

A patient has finished the exercise portion of a stress test and the treadmill belt has stopped. What does monitoring during the recovery period require?

• a.Recording ends when the belt stops, and the patient waits in the reception area until discharge
• b.Recovery tracings are recorded only for the patients who reported symptoms during the exercise stages
• c.The patient stays monitored until heart rate, blood pressure, and the EKG return toward baseline✓
• d.Monitoring stops once the heart rate drops below the target rate calculated for the patient's age

Recovery is part of the test, not the end of it. Ischemic ST changes and exercise-induced arrhythmias frequently appear or persist after exercise stops, and hypotension and fainting are most likely in the first minutes off the treadmill, so electrodes and the blood pressure cuff stay on and readings continue until heart rate, pressure, and the tracing approach the patient's baseline. Removing the leads when the belt stops throws away the segment most likely to show the abnormality. Recording recovery only for symptomatic patients misses silent ischemia, and dropping below the target heart rate says nothing about whether pressure or the ST segments have recovered.

A technician has to move a heavy portable EKG machine into a room and then help turn a patient in bed. Which approach best protects the technician from injury?

• a.Reach across the bed and draw the patient toward the far rail in one smooth motion
• b.Lift with the arms and shoulders while the knees stay straight and the feet stay together
• c.Raise the bed toward waist height, keep the feet apart, bend at the knees, and push the machine rather than pull it✓
• d.Turn at the waist to swing the machine into position instead of stepping around it

Sound body mechanics keep the load close, the base of support wide, and the work near waist level, so the large muscles of the legs do the lifting and the spine stays neutral. Pushing a wheeled machine uses body weight and is easier on the back than pulling it. Reaching across a bed puts the load far from the technician's center of gravity and is a common cause of back strain, which is why a turn is done from the near side or with a second person. Keeping the knees locked while lifting with the arms and twisting at the waist under load are the two motions most often behind lifting injuries.

A technician with a fever and a productive cough is assigned to record a 12-lead on a neutropenic patient in a protective environment room. What should the technician do?

• a.Enter wearing a surgical mask and gloves and keep the visit as brief as the study allows
• b.Record the tracing while standing at arm's length from the patient's head the whole time
• c.Report the symptoms to the supervisor and ask to be reassigned away from this patient✓
• d.Delay the study until the end of the shift and clean the machine first

A protective environment exists to keep organisms away from a patient whose neutrophil count leaves almost no defense, and a staff member with fever and a productive cough is exactly the exposure it is designed to exclude. Reporting the symptoms so the assignment can be changed protects the patient and follows the occupational health policy that governs working while ill. A surgical mask reduces droplet spread but does not make a febrile, coughing worker safe for a neutropenic patient, and no working distance is safe when electrodes must be placed on the chest. Postponing the study to the end of the shift changes only the hour, not the risk the technician brings into the room.

While removing electrodes from a patient with a bleeding puncture site, a technician gets a splash of blood in one eye. What is the immediate action?

• a.Flush the eye at an eyewash station with water for at least 15 minutes, then report the exposure✓
• b.Blot the eye with gauze, finish the study, and rinse at the sink once the patient has left the room
• c.Notify the supervisor and complete the exposure report form before rinsing the eye
• d.Rinse the eye briefly with sterile saline and carry on with the next scheduled patient

A mucous membrane exposure is decontaminated first, and the standard first aid is copious flushing with water or saline at an eyewash station for a sustained period, on the order of 15 minutes. Reporting follows immediately afterward so that the source patient can be evaluated and post-exposure prophylaxis considered within the window in which it works, but paperwork does not come before flushing. Blotting with gauze spreads rather than removes the blood and delays irrigation for the length of a study. A few seconds of saline is not irrigation, and continuing to the next patient skips the reporting that makes any later treatment or claim possible.

The code team has arrived and taken over the resuscitation of a monitored patient. How can the EKG technician best help while the code continues?

• a.Announce a formal rhythm interpretation and tell the team which drug should be given
• b.Take the pads from the defibrillator and place them while compressions are in progress
• c.Run rhythm strips, note the times of events, and keep the tracings for the record✓
• d.Leave and ask the supervisor which tasks are permitted during a code

Once the code team is present, the technician contributes within the certified scope: producing and labeling rhythm strips, recording the times of rhythm changes and interventions, and fetching supplies. That documentation is genuinely useful and is work the team cannot do while managing the airway and compressions. Calling the monitor for the team is ordinary practice, but announcing a formal interpretation and telling the team which drug to give converts that reading into a treatment decision, which a CET is not credentialed to make. Applying defibrillator pads belongs to the team members trained and authorized to defibrillate. Walking out of an active code to ask what is allowed removes a trained pair of hands at the worst possible moment.

A portable EKG machine is being set up in a crowded patient room, and the nearest wall outlet sits behind the bed. What is the correct way to power the machine?

• a.Plug it into a hospital-grade wall outlet, or run the study on the machine's own battery✓
• b.Plug it into the multi-outlet power strip that already serves the infusion pumps and the bed
• c.Run a household extension cord under the bed so that the outlet behind it can be reached easily
• d.Join a second power strip to the first one so that the cord will reach the machine

Equipment used in the patient care vicinity is plugged directly into a hospital-grade receptacle, and a machine with a charged battery can simply be run on battery power when no suitable outlet is within reach. Loading a portable machine onto a power strip that is already carrying pumps and a bed adds to a shared load and to a shared point of failure, and daisy-chaining one relocatable power tap into another is prohibited in patient care areas for that reason. A household extension cord is not built for this service, and running it under a bed exposes it to crushing and turns it into a trip hazard. Convenience does not justify adding a failure point between the machine and the wall.
