WRITTEN (100%). GRADED A+



About this resource
Becoming a Certified Nursing Assistant is a noble and demanding career. The state
competency exam is divided into two parts: a written/oral test (65-100 questions)
and a clinical skills test. These 200 questions cover the most frequently tested
concepts, from preventing pressure ulcers to handling medical emergencies.

How to use this guide: Cover the bold italic answer on the right, try to answer
mentally, then read the italic rationale to understand the "why" behind the
correct choice. This mimics the critical thinking required on exam day.




Domain 1: Infection Control & Standard Precautions
(Questions 1-25)
1. What is the most important action a CNA can take to prevent the spread of
infection?

 a) Wearing gloves for all resident contact
 b) Isolating the resident immediately
 c) Asking visitors to wear masks

, d) Performing hand hygiene
 Rationale: Hand hygiene (washing with soap and water or using alcohol-based
rub) is the single most effective method to prevent the transmission of pathogens.
Gloves are not needed for every contact, but clean hands are mandatory.

2. When should a CNA use an alcohol-based hand rub instead of soap and water?

 a) When hands are visibly soiled with blood
 b) When hands are not visibly dirty and C. difficile is not present
 c) After removing gloves
 d) Before eating
 Rationale: Alcohol-based rubs are effective for routine decontamination if hands
aren't visibly soiled. However, for C. diff, norovirus, or visible soil, soap and water
are required because alcohol does not kill spore-forming bacteria.

3. What does "Standard Precautions" assume?

 a) Only residents with a known diagnosis are infectious
 b) Every person’s blood and body fluids are potentially infectious
 c) Only healthcare workers need protection
 d) Gloves replace hand washing
 Rationale: Standard Precautions assume all patients/residents are potentially
infected with bloodborne pathogens (HIV, HBV) or other microbes, regardless of
their diagnosis.

4. A resident is on Transmission-Based Precautions for airborne illnesses (like TB).
Which mask must you wear?

 a) Surgical mask
 b) N95 respirator mask
 c) Cloth mask
 d) No mask is needed
 *Rationale: Airborne precautions require an N95 or higher-level respirator to filter tiny
particles that remain suspended in the air. Surgical masks protect against droplets only.*

5. You are changing a soiled brief. After removing your gloves, what do you do
next?

 a) Apply new gloves
 b) Perform hand hygiene
 c) Document the output
 d) Spray the room with disinfectant

, Rationale: Gloves are not 100% perfect. Immediate hand hygiene after glove
removal prevents microbes that may have contaminated your hands during doffing
from spreading.

6. When is it acceptable to reuse a disposable mask?

 a) If it was worn for less than 10 minutes
 b) If it belongs to the same resident
 c) If you wipe it with alcohol
 d) Never – they are single-use only
 Rationale: Disposable masks are designed for one use. Reusing them compromises
the filter integrity and introduces contamination.

7. What is the correct order for removing PPE?

 a) Mask, gloves, gown
 b) Gloves, gown, mask
 c) Gloves, gown, mask
 d) Gown, mask, gloves
 Rationale: Remove the most contaminated (gloves) first, then the gown (tying it
inside out), and finally the mask (by the straps, not the front).

8. While making a bed, you get a small splash of urine on your forearm. What
should you do?

 a) Ignore it; it’s just urine
 b) Wipe it with a tissue
 c) Wash the area with soap and water immediately
 d) Put gloves on over it
 Rationale: Any exposure to body fluids on skin requires immediate washing with
soap and water to remove pathogens before they enter mucous membranes or
broken skin.

9. A resident has Methicillin-resistant Staphylococcus aureus (MRSA) in a wound.
What is required?

 a) Transfer to a hospital
 b) Contact Precautions (gloves and gown)
 c) No precautions; it's not contagious
 d) Reverse isolation
 Rationale: MRSA is spread by contact (touching wound drainage or contaminated
surfaces). Contact precautions (gloves, gown, dedicated equipment) are used.

, 10. How long should you rub your hands together with soap during hand washing?

 a) 5 seconds
 b) At least 20 seconds
 c) 1 minute
 d) Until the soap bubbles
 Rationale: CDC guidelines state a minimum of 20 seconds of vigorous rubbing to
mechanically remove debris and kill microbes effectively.

11. The "chain of infection" includes all EXCEPT:

 a) Reservoir
 b) Portal of exit
 c) Antibiotics
 d) Susceptible host
 Rationale: Antibiotics treat infection but are not a "link" in the chain of
transmission. The six links are: Infectious agent, Reservoir, Portal of exit, Mode of
transmission, Portal of entry, Susceptible host.

12. A CNA is caring for a resident with Clostridioides difficile (C. diff). Which hand
hygiene method is correct?

 a) Alcohol-based hand rub only
 b) Soap and running water only
 c) Either soap or alcohol
 d) Bleach wipes only
 Rationale: C. diff spores are not killed by alcohol. Mechanical washing with soap
and water is required to physically remove the spores.

13. What is the purpose of medical asepsis (clean technique)?

 a) To kill all microorganisms, including spores
 b) To reduce the number and spread of microorganisms
 c) To create a sterile field
 d) To cure existing infections
 Rationale: Medical asepsis reduces pathogens to a safe level. Surgical asepsis
(sterile technique) kills all microbes.

14. You are about to pour a liquid medication for a resident. Where should the
label be positioned?

 a) Facing down
