Section 1: Infection Control & Safety (Questions 1–20)



Question 1
A CNA is caring for a resident with a suspected Clostridioides difficile (C. diff) infection. Which
infection control practice is most critical beyond standard precautions?

A) Wearing a surgical mask during all direct contact
B) Using alcohol-based hand sanitizer exclusively

, 2



C) Performing hand hygiene with soap and water after glove removal
D) Placing the resident in a negative-pressure isolation room

Correct - detailed answer 100% correct :- C
Rationale: C. diff spores are resistant to alcohol-based hand sanitizers. Soap and water must be
used for hand hygiene because the mechanical action of washing physically removes spores.
Standard precautions alone are insufficient; contact precautions including soap-and-water
handwashing are essential.



Question 2
A CNA discovers a small fire in a resident's wastebasket. After removing the resident from the
room, what is the CNA's priority action?

A) Locate and use the nearest fire extinguisher
B) Close the door to contain the fire and activate the alarm
C) Run to notify the charge nurse immediately
D) Evacuate all residents on the unit

Correct - detailed answer 100% correct :- B
Rationale: The RACE protocol (Rescue, Alarm, Contain, Extinguish) directs that after rescuing
the resident, the CNA should activate the alarm and contain the fire by closing doors. This
prevents fire spread while ensuring help is summoned.



Question 3
A CNA is removing contaminated gloves after providing perineal care. Which technique correctly
prevents contamination?

A) Grasp the outside of one glove near the wrist and peel it off, then slide fingers under the
remaining glove and peel it off from the inside
B) Pull both gloves off by the fingers simultaneously
C) Remove gloves by grasping the fingertips and pulling outward
D) Shake the gloves off into the designated waste container

Correct - detailed answer 100% correct :- A
Rationale: The correct doffing technique involves touching only the outside of the first glove
and only the inside of the second glove, preventing contamination of the CNA's skin. This is the
standard CDC-recommended method.

Question 4
A CNA is caring for a resident on transmission-based precautions for airborne infection. Which
personal protective equipment (PPE) sequence is correct for donning?

A) Gown, mask, gloves, eye protection
B) Mask, eye protection, gown, gloves
C) Gown, mask, eye protection, gloves
D) Gloves, gown, mask, eye protection

Correct - detailed answer 100% correct :- C
Rationale: The correct donning sequence is gown first, then mask, then eye protection, and
gloves last. This sequence ensures proper coverage and minimizes contamination risk during
application.



Question 5
A resident with an indwelling urinary catheter develops cloudy, foul-smelling urine. The CNA's
most appropriate action is to:

A) Increase the resident's fluid intake and document
B) Irrigate the catheter to clear the obstruction
C) Report the finding to the charge nurse immediately
D) Change the urinary drainage bag

Correct - detailed answer 100% correct :- C
Rationale: Cloudy, foul-smelling urine in a catheterized resident is a sign of possible urinary
tract infection. The CNA must report this finding promptly; irrigation and catheter manipulation
are outside the CNA scope of practice.



Question 6
When should a CNA perform hand hygiene in a healthcare setting?

A) Only before providing direct patient care
B) Before and after providing care, after removing gloves, and after contact with body fluids
C) Only when hands are visibly soiled
D) At the beginning and end of each shift only

Correct - detailed answer 100% correct :- B
Rationale: Hand hygiene is required before and after patient contact, after glove removal, after

contact with body fluids, and between tasks on the same patient. This is the single most
effective infection prevention measure.



Question 7
A CNA is preparing to assist a resident with oral care. The resident has dentures. What step
should the CNA take first?

A) Rinse the dentures in hot water to sterilize them
B) Place a towel in the sink and fill it with cool or warm water
C) Wash the dentures with soap and hot water
D) Remove the dentures and place them directly on the bedside table

Correct - detailed answer 100% correct :- B
Rationale: Placing a towel in the sink and using cool or warm water prevents breakage if the
dentures are accidentally dropped. Hot water can warp dentures, and they should never be
placed directly on hard surfaces.



Question 8
A CNA observes a coworker failing to perform hand hygiene between residents. What is the
CNA's most appropriate response?

A) Ignore the behavior to avoid conflict
B) Report the observation to the charge nurse immediately
C) Remind the coworker privately about proper hand hygiene
D) Document the observation in the resident's medical record

Correct - detailed answer 100% correct :- C
Rationale: The CNA should first address the issue directly and privately with the coworker as a
professional courtesy. If the behavior continues, it should be reported to the charge nurse.
Patient safety is paramount.



Question 9
Which of the following situations requires the use of gloves by a CNA?

A) Assisting a resident with ambulation
B) Taking a resident's oral temperature
