A) Wearing gloves at all times during a shift
B) Washing hands thoroughly before and after resident contact
C) Spraying disinfectant in the hallways daily
,D) Keeping all resident room windows closed
Answer: B) Washing hands thoroughly before and after resident contact

D) Wiping hands with a dry paper towel
Answer: C) Washing hands vigorously with antimicrobial soap and water

friction, running water, and soap are mechanically required to loosen and rinse the
resilient bacterial spores from the skin surface.

both Contact and Droplet Precautions, which item should be put on first?
A) Gloves
B) Mask or respirator
C) Goggles or face shield
D) Isolation gown

Gloves. The gloves are applied last so they can be pulled up and secure over the
cuffs of the gown.

which item must be removed first to minimize self-contamination?
A) Isolation gown
B) Surgical mask
,C) Gloves
D) Goggles
Answer: C) Gloves
Explanation: Gloves are considered the most heavily contaminated piece of PPE
because they directly touch the resident and bodily fluids. They must be removed
first using a safe glove-to-glove, skin-to-skin technique before touching clean areas
of the body or other PPE.
Question 5: A Nurse Aide nicks their finger on a used razor blade while assisting a
resident with shaving. What is the immediate first step the aide should take?
A) Complete an incident report at the nurses' station
B) Wash the puncture site thoroughly with soap and water
C) Apply a band-aid and finish the shift tasks
D) Ask the resident if they have any bloodborne illnesses
Answer: B) Wash the puncture site thoroughly with soap and water
Explanation: Immediate first aid for any sharps or needle-stick injury requires
washing the area thoroughly with soap and water to reduce the viral load and
mechanically flush out pathogens. Reporting to a supervisor occurs immediately
after this step.
Question 6: What does the letter "A" stand for in the standard fire safety acronym
RACE?
A) Assemble residents in the courtyard
B) Activate the fire alarm system
C) Apply water to the base of the fire
D) Assist the charge nurse with a headcount
Answer: B) Activate the fire alarm system
Explanation: The acronym RACE represents the sequence of actions during a fire:
R = Rescue/Remove residents from immediate danger; A = Alarm (activate the fire
alarm box or call out); C = Confine/Contain the fire by closing doors; E =
Extinguish or Evacuate.
, Question 7: When utilizing a fire extinguisher to put out a small trash can fire, the
Nurse Aide should pull the pin and aim the nozzle at which location?
A) The very top of the flames
B) The middle of the smoke cloud
C) The base of the fire
D) The side of the container
Answer: C) The base of the fire
Explanation: The PASS acronym guides fire extinguisher use: P = Pull the pin; A =
Aim at the base of the fire; S = Squeeze the handle; S = Sweep from side to side.
Aiming at the base targets the fuel source fueling the fire.
Question 8: A resident is found sitting on the floor of their room crying, but is unable
to explain what happened. What should the Nurse Aide do first?
A) Pick the resident up and put them back into bed immediately
B) Leave the room to find a mechanical lift
C) Stay with the resident, check for obvious injuries, and call for the charge nurse
D) Administer pain medication if available in the room
Answer: C) Stay with the resident, check for obvious injuries, and call for the
charge nurse
Explanation: A nurse aide must never move a resident who has experienced an
unwitnessed fall until a licensed nurse performs an assessment for structural or
spinal injuries. Moving them prematurely could worsen a fracture.
Question 9: Which of the following examples represents an engineering control used
to eliminate or minimize workplace exposure to bloodborne pathogens?
A) Wearing a plastic apron during a bed bath
B) Using a sharps disposal container for discarded razors
C) Scrubbing the utility room counters with bleach
D) Placing dirty linens in a water-soluble bag
Answer: B) Using a sharps disposal container for discarded razors
