CSLB General Building (B) — All Questions

Two assistants discuss a patient's HIV status at the front desk while other patients wait nearby. Which principle was violated?

• a.The right of the patient to refuse treatment
• b.The requirement to obtain a signed treatment plan
• c.The rule that all records must be kept for seven years
• d.The requirement to safeguard protected health information and disclose only the minimum necessary✓

Discussing a patient's diagnosis where others can overhear violates the obligation to safeguard protected health information and to limit disclosures to the minimum necessary for the task. The right to refuse treatment and the signing of a treatment plan concern consent, not confidentiality. Record retention periods are set by state law and are unrelated to an overheard conversation.HIPAA Privacy Rule (45 CFR Part 164)

An assistant writes the wrong tooth number in a paper chart entry. What is the correct way to fix it?

• a.Cover the error with correction fluid and write the correct number over it
• b.Draw a single line through the error, write the correction, and add initials and the date✓
• c.Erase the entry completely and rewrite the note
• d.Tear out the page and start a new chart

A single line through the error with the correction, initials, and date preserves the original entry and shows who changed it and when, which keeps the record legally defensible. Correction fluid, erasing, and removing pages obliterate the original entry and can be interpreted as falsifying a legal document. The chart is a legal record, so nothing in it may be destroyed or hidden.

Which combination of elements must be covered for a patient's consent to be considered informed?

• a.The fee and the appointment length only
• b.The dentist's credentials and years in practice
• c.The nature of the procedure, its risks and benefits, reasonable alternatives, and the consequences of declining treatment✓
• d.A verbal statement that the procedure is routine

Informed consent requires that the patient understand the nature of the proposed treatment, its risks and expected benefits, reasonable alternatives, and what may happen if treatment is declined, with an opportunity to ask questions. Fees and scheduling are business matters, not clinical disclosures. A dentist's credentials and a reassurance that a procedure is routine do not give the patient the information needed to weigh the decision.

A patient asks the assistant, "Do you think this dark spot on my x-ray is a cavity?" What is the appropriate response?

• a.Give the patient a definitive answer based on what the image appears to show
• b.Explain that the dentist will review and interpret the radiograph, and offer to relay the patient's question✓
• c.Tell the patient the finding is definitely nothing to worry about
• d.Recommend a filling and schedule the appointment

Diagnosing conditions, interpreting radiographic findings for the patient, and prescribing treatment fall outside the dental assistant's scope of practice and belong to the dentist. Offering a definitive answer, reassuring the patient that nothing is wrong, or recommending a restoration all constitute diagnosis or treatment planning. Referring the question to the dentist keeps the assistant within legal scope while still serving the patient.

A patient who has been coming to the practice for six years arrives for a filling. What should be done with the medical history?

• a.Review and update it at this visit, including current medications and any recent health changes✓
• b.Use the history taken at the first visit, since it is already on file
• c.Update it only if the patient volunteers new information
• d.Update it once every five years

The medical history must be reviewed and updated at each visit, because new medications, allergies, pregnancies, and conditions such as recent cardiac events change treatment and drug safety decisions. Relying on an old form or waiting for the patient to volunteer information misses changes the patient may not realize are relevant. A five-year interval is far too long to detect clinically significant developments.

A patient with a history of angina develops crushing chest pain in the chair. Besides stopping treatment and activating emergency medical services, which drug from the office emergency kit is typically indicated?

• a.Diphenhydramine
• b.Albuterol inhaler
• c.Nitroglycerin, administered sublingually✓
• d.Oral glucose gel

Sublingual nitroglycerin is the standard emergency drug for angina because it dilates coronary vessels and relieves ischemic chest pain. Diphenhydramine is used for allergic reactions, and albuterol is for bronchospasm in asthma. Glucose gel treats hypoglycemia and would do nothing for cardiac chest pain, so recognizing the correct emergency category is essential.

Where must Safety Data Sheets for the chemicals used in a dental office be kept?

• a.In the dentist's locked personal office, available on request
• b.At the manufacturer's headquarters
• c.Only in electronic form on a password-protected server the staff cannot access
• d.Readily accessible to all employees in their work area during every work shift✓

Safety Data Sheets must be readily accessible to employees in their work area throughout each shift, so that hazard, first aid, and spill information can be reached immediately in an emergency. Storing them in a locked office or leaving them with the manufacturer defeats that purpose. An electronic format is acceptable only when employees can actually access it without barriers.OSHA Hazard Communication Standard (29 CFR 1910.1200)

An assistant pours a disinfectant concentrate into a spray bottle that will be used later in the day by other staff. What must be done with the bottle?

• a.Label it with the product identifier and the hazard information required for a secondary container✓
• b.Leave it unlabeled because it will be used the same day
• c.Write only the assistant's initials on the bottle
• d.Mark it simply "cleaner" with a marker

A secondary container that will be used by other employees or left beyond the immediate use of the person who filled it must carry the product identifier and the required hazard information. An unlabeled bottle leaves coworkers unable to identify the chemical in a spill or exposure. Initials identify a person, not a hazard, and a vague word like "cleaner" does not convey the product identity or its hazards.OSHA Hazard Communication Standard (29 CFR 1910.1200)

A chemical sterilant splashes into an assistant's eye. What is the correct immediate response?

• a.Rub the eye with a gauze square and apply an eye patch
• b.Flush the eye at the eyewash station with tepid water for at least 15 minutes, then seek medical attention✓
• c.Rinse for 30 seconds and return to work
• d.Apply a neutralizing chemical directly to the eye

Chemical splashes to the eye require continuous flushing with tepid water for at least 15 minutes, holding the eyelids open, followed by medical evaluation and reporting under the office's exposure procedures. Rubbing the eye drives the chemical deeper and can abrade the cornea. A 30-second rinse is far too brief, and applying a neutralizer can cause an additional chemical reaction and further injury.OSHA Hazard Communication Standard (29 CFR 1910.1200)

A patient becomes pale, sweaty, and faints briefly in the dental chair. What is the correct initial positioning?

• a.Sit the patient fully upright and offer water
• b.Have the patient stand and walk to increase circulation
• c.Place the patient supine with the legs slightly elevated to improve blood flow to the brain✓
• d.Turn the patient face down to protect the airway

Syncope is managed by placing the patient supine with the legs slightly elevated, which restores cerebral blood flow, along with assessing airway, breathing, and circulation and administering oxygen if indicated. Sitting the patient upright or having them stand worsens cerebral hypoperfusion and risks a fall. A face-down position compromises rather than protects the airway.

Which administrative measure do CDC dental guidelines recommend as the foundation of a practice's infection prevention program?

• a.Posting a sign in the reception area stating the office is sterile
• b.Purchasing the most expensive sterilizer available
• c.Relying on each employee to follow whatever method they prefer
• d.Developing written infection prevention policies and assigning at least one trained person to coordinate the program✓

CDC guidance calls for written policies and procedures based on evidence, with at least one trained individual assigned responsibility for coordinating the infection prevention program and reassessing it periodically. Signage and equipment cost do not create consistent practice. Letting each employee choose their own method produces inconsistent care and makes training and accountability impossible.CDC Guidelines for Infection Control in Dental Health-Care Settings

An attorney calls and asks the office to fax a patient's complete dental record for a personal injury case. What should the assistant do?

• a.Fax the record immediately because an attorney is a professional
• b.Read the treatment notes aloud over the phone instead of faxing
• c.Refuse to acknowledge that the person is a patient and hang up
• d.Explain that a signed authorization from the patient is required before records can be released✓

Releasing records to a third party such as an attorney requires a valid written authorization signed by the patient, which specifies what information may be disclosed and to whom. Faxing on request or reading notes aloud discloses protected health information without authorization. Simply hanging up is unnecessary; the correct response is to explain the authorization requirement and follow the office's release procedure.HIPAA Privacy Rule (45 CFR Part 164)

The medical history shows a documented latex allergy. Which plan best protects the patient?

• a.Use latex gloves but change them more frequently
• b.Treat the patient normally and keep an antihistamine nearby
• c.Schedule the patient early in the day and use latex-free gloves, dam, and other supplies in a room prepared to avoid latex residue✓
• d.Ask the patient to take an antihistamine before the appointment and proceed with usual materials

A latex-allergic patient should be scheduled early, ideally as the first appointment, in a treatment room where airborne latex particles have settled, and every latex-containing item must be replaced with a latex-free alternative. Changing latex gloves more often still exposes the patient. Premedicating with an antihistamine does not prevent a reaction and does not substitute for removing the allergen.

A pregnant patient needs a radiograph to diagnose a painful, swollen molar. What is the correct approach?

• a.Take the necessary radiograph using a lead apron with thyroid collar and the fastest receptor, since needed diagnostic imaging is not contraindicated by pregnancy✓
• b.Refuse all imaging until after delivery, regardless of symptoms
• c.Take a full-mouth series to document the entire condition
• d.Double the exposure time to compensate for the lead apron

Pregnancy does not contraindicate a radiograph that is needed for diagnosis; the image should be taken with proper shielding, a fast receptor, and the fewest exposures necessary. Refusing all imaging can delay treatment of an active infection that itself endangers the patient. A full-mouth series is unnecessary for a single symptomatic tooth, and increasing exposure time raises dose without any benefit.FDA/ADA Dental Radiographic Examinations: Recommendations for Patient Selection and Limiting Radiation Exposure

Which requirement best reflects emergency preparedness for a dental team?

• a.Only the dentist needs current basic life support certification
• b.All clinical team members maintain current basic life support certification and the office rehearses emergency drills with a stocked, in-date emergency kit and oxygen✓
• c.An emergency kit is sufficient even if some drugs are expired
• d.Emergency roles are decided at the moment an emergency occurs

Preparedness requires that all clinical staff hold current basic life support certification, that the team practices drills with assigned roles, and that the emergency kit and oxygen are checked regularly so nothing is expired or empty. Limiting certification to the dentist leaves the team unable to respond if the dentist is occupied. Expired drugs may fail when needed, and improvising roles during a crisis wastes critical time.
