CSLB General Building (B) — All Questions

Under standard precautions, how should a medical assistant treat every patient's blood and body fluids?

• a.As infectious only when the patient has a known diagnosis of hepatitis or HIV
• b.As potentially infectious for all patients, regardless of diagnosis✓
• c.As safe if the patient looks healthy and reports no symptoms
• d.As infectious only when visible blood is present

Standard precautions require treating blood, all body fluids except sweat, non-intact skin, and mucous membranes as potentially infectious for every patient, because infection status is often unknown. Waiting for a known diagnosis or visible blood leaves staff exposed to undiagnosed carriers. A healthy appearance says nothing about bloodborne pathogen status.CDC Standard Precautions guidelines

What is the correct sequence for putting on personal protective equipment before entering an isolation room?

• a.Gloves, gown, mask, goggles
• b.Mask, gloves, gown, goggles
• c.Goggles, gloves, mask, gown
• d.Gown, mask or respirator, goggles or face shield, then gloves✓

PPE is donned gown first, then mask or respirator, then eye protection, and gloves last so the glove cuffs cover the gown sleeves and seal the wrists. Putting gloves on first makes it impossible to tie a gown or fit a respirator without contaminating them. Any order that leaves gloves before the gown breaks the seal that protects the wrists.CDC Standard Precautions guidelines

When removing personal protective equipment after patient care, which item is removed first?

• a.Gloves, because they are the most contaminated✓
• b.The N95 respirator, because it is hardest to keep clean
• c.The gown, so the arms are free
• d.Eye protection, so vision improves for the rest of the process

Gloves are removed first because they carry the heaviest contamination, followed by eye protection, then the gown, with the mask or respirator removed last outside the patient room. Taking off a respirator first would require touching the face with contaminated gloves. Removing the gown before the gloves drags contamination across clean clothing.CDC Standard Precautions guidelines

A medical assistant's hands are visibly soiled after assisting with a procedure. What is the appropriate hand hygiene method?

• a.Alcohol-based hand rub, because it works faster
• b.A quick rinse with plain water only
• c.Wash with soap and running water for at least 20 seconds, covering all surfaces✓
• d.Wipe hands on a clean paper towel and apply lotion

Alcohol-based rubs do not remove visible soil or reliably kill spore-forming organisms, so visibly soiled hands must be washed with soap and running water for at least 20 seconds. Water alone does not lift oils and organic material. Wiping with a towel simply spreads contamination and lotion seals it against the skin.CDC hand hygiene guidelines

A patient with suspected active pulmonary tuberculosis arrives at the clinic. Which precautions are required?

• a.Contact precautions with gown and gloves only
• b.Airborne precautions, including a fit-tested N95 respirator and placing the patient in an airborne infection isolation room✓
• c.Droplet precautions with a surgical mask worn only by the medical assistant
• d.Standard precautions alone, since tuberculosis is not contagious in a clinic

Tuberculosis spreads through droplet nuclei that remain suspended in air, so airborne precautions with a fit-tested N95 or higher respirator and a negative-pressure isolation room are required. Gown and gloves address contact spread, which is not the main route for TB. A surgical mask does not filter the small airborne particles that transmit tuberculosis.CDC Transmission-Based Precautions guidelines

Which infection is managed primarily with droplet precautions?

• a.Measles
• b.Chickenpox
• c.Pulmonary tuberculosis
• d.Influenza✓

Influenza spreads through large respiratory droplets that travel only a short distance, so droplet precautions with a surgical mask when within about 6 feet of the patient are appropriate. Measles, chickenpox, and tuberculosis are transmitted through small airborne particles and require airborne precautions with an N95 respirator. Confusing the two categories leaves staff underprotected.CDC Transmission-Based Precautions guidelines

Under the OSHA Bloodborne Pathogens Standard, what must the employer provide to employees with occupational exposure risk?

• a.The hepatitis B vaccination series at no cost to the employee, offered within 10 working days of initial assignment✓
• b.A one-time cash payment instead of vaccination
• c.Vaccination only if the employee agrees to pay half the cost
• d.Vaccination only after the employee has a documented needlestick

The standard requires employers to offer the hepatitis B vaccine series free of charge within 10 working days of initial assignment to work with occupational exposure, and employees who decline must sign a declination form. Charging the employee or paying cash instead does not satisfy the rule. Waiting until after an exposure defeats the purpose of pre-exposure protection.OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030)

A medical assistant sustains a needlestick from a used blood collection needle. What should be done first?

• a.Recap the needle and finish the patient's remaining tubes
• b.Apply a bandage and report it at the end of the shift
• c.Wash the site with soap and water immediately, then report the exposure so post-exposure evaluation can begin✓
• d.Squeeze the wound hard to force out blood and apply bleach to the skin

Immediate washing with soap and water, followed by prompt reporting so the employer can start the confidential post-exposure medical evaluation and follow-up, is the required response. Delaying the report can put timely prophylaxis out of reach. Squeezing the wound and applying caustic agents such as bleach to skin are not recommended and can worsen tissue injury.OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030)

How should used needles and lancets be handled in the clinic?

• a.Recap them with two hands and place them in a red bag
• b.Place them uncapped, immediately after use, into a labeled puncture-resistant sharps container, replacing the container before it is overfilled✓
• c.Break the needle off the syringe and discard both in regular trash
• d.Store them in a cardboard box until enough accumulate for pickup

Contaminated sharps go directly into a closable, puncture-resistant, leakproof sharps container labeled with the biohazard symbol, and containers are replaced routinely rather than overfilled. Two-handed recapping is prohibited because it is a leading cause of needlesticks. Breaking or bending needles and using ordinary trash or cardboard creates a serious puncture and exposure hazard.OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030)

Which statement correctly distinguishes medical asepsis from surgical asepsis?

• a.Medical asepsis destroys all microorganisms and spores, while surgical asepsis only reduces them
• b.The two terms mean exactly the same thing
• c.Medical asepsis is used only in operating rooms
• d.Medical asepsis reduces the number of microorganisms, while surgical asepsis removes all microorganisms and spores from an object or area✓

Medical asepsis, or clean technique, reduces the number and spread of pathogens through handwashing, gloves, and disinfection, while surgical asepsis, or sterile technique, eliminates all microorganisms including spores. The definitions are not interchangeable, and reversing them describes the opposite practice. Medical asepsis is used throughout the clinic, not only in surgical settings.

A tube of blood breaks on the exam room floor. After putting on gloves and appropriate PPE, what is the correct cleanup procedure?

• a.Cover and absorb the spill, remove broken glass with forceps or a brush and dustpan, then disinfect the area with an approved solution such as 1 part bleach to 10 parts water✓
• b.Pick up the glass with gloved hands and rinse the floor with plain water
• c.Mop the spill with a dry cloth and leave the area to air dry
• d.Spray air freshener and place a wet floor sign until housekeeping arrives the next day

Blood spills are absorbed first, sharp fragments are removed mechanically with forceps or a brush and dustpan rather than by hand, and the surface is then disinfected with an EPA-registered agent or freshly mixed 1:10 bleach solution. Handling glass with gloved hands risks a puncture and exposure. Plain water and air drying do not disinfect, and delaying cleanup leaves an active biohazard.

A patient with a draining wound colonized with MRSA is placed in an exam room. Which PPE is required when providing direct care?

• a.A face shield only
• b.An N95 respirator only
• c.Gown and gloves, applied before entering and removed before leaving the room✓
• d.No PPE is needed as long as hands are washed afterward

MRSA in a draining wound calls for contact precautions, meaning a gown and gloves are donned before entry and removed before exiting, with hand hygiene afterward. A face shield is added only when splashing is likely. An N95 respirator addresses airborne organisms, and hand hygiene alone does not prevent contamination of clothing and skin during direct care.CDC Transmission-Based Precautions guidelines

A medical assistant needs to know the health hazards and first aid steps for a disinfectant used in the clinic. Where should this information be found?

• a.In the patient's medical record
• b.On the Safety Data Sheet maintained for that chemical✓
• c.In the appointment scheduling software
• d.On the clinic's insurance fee schedule

Safety Data Sheets list hazards, handling and storage requirements, exposure controls, and first aid measures for each hazardous chemical, and employers must keep them readily accessible to employees. Patient records contain clinical information about people, not chemicals. Scheduling software and fee schedules are administrative tools with no safety content.OSHA Hazard Communication Standard (29 CFR 1910.1200)

Smoke is coming from a supply room in the clinic. Using the RACE emergency response sequence, what is the first action?

• a.Extinguish the fire with the nearest extinguisher
• b.Confine the fire by closing all doors
• c.Activate the alarm and call 911
• d.Rescue or remove anyone in immediate danger✓

RACE stands for Rescue, Alarm, Confine, Extinguish, so removing people from immediate danger comes first, followed by activating the alarm, closing doors to confine smoke, and only then attempting extinguishment if it is safe. Attempting to fight the fire first delays evacuation and can trap staff and patients. Confinement is important but follows rescue and alarm.

Which waste item belongs in a red biohazard bag rather than regular trash?

• a.Gauze saturated with blood from a wound dressing✓
• b.An empty cardboard glove box
• c.Paper table covering with no visible soiling
• d.An unopened, expired package of sterile gauze

Items saturated or dripping with blood or other potentially infectious material are regulated medical waste and go into a labeled red biohazard bag. Clean packaging, unsoiled paper, and unused supplies are ordinary waste or can be discarded per facility policy. Overfilling biohazard bags with non-regulated waste raises disposal costs without adding safety.

Which link in the chain of infection is broken when a medical assistant performs proper hand hygiene between patients?

• a.The infectious agent's ability to reproduce
• b.The susceptible host's immune system
• c.The mode of transmission✓
• d.The portal of entry into the reservoir

Hand hygiene interrupts the mode of transmission, because contaminated hands are the most common vehicle for carrying pathogens from one person to another. Handwashing does not change how an organism reproduces or strengthen the host's immunity. The reservoir has a portal of exit rather than a portal of entry, so that description misstates the chain.
