Competency for CNA Final Exam Success
Question 1: Which of the following is the most effective method for preventing the
spread of infection in a healthcare setting?
A. Wearing gloves at all times
B. Using air purifiers in patient rooms
C. Performing proper hand hygiene
D. Administering prophylactic antibiotics
CORRECT ANSWER: C. Performing proper hand hygiene
RATIONALE: Hand hygiene is universally recognized by the CDC and WHO as the single
most important practice to prevent healthcare-associated infections. While gloves and
other precautions are important, they do not replace the fundamental need for
thorough handwashing or alcohol-based hand rubs before and after patient contact.
Question 2: When measuring a resident's oral temperature, which action should
the CNA avoid?
A. Placing the thermometer under the tongue
B. Asking the resident to keep their mouth closed
C. Taking the temperature immediately after the resident drinks hot coffee
D. Waiting 15-30 minutes after eating or drinking before taking the temperature
CORRECT ANSWER: C. Taking the temperature immediately after the resident
drinks hot coffee
RATIONALE: Consuming hot or cold beverages can temporarily alter oral temperature
readings, leading to inaccurate results. CNAs should wait at least 15-30 minutes after
eating, drinking, or smoking before obtaining an oral temperature to ensure accuracy.
Question 3: A resident with right-sided weakness after a stroke needs assistance
with ambulation. Which side should the CNA stand on for optimal support?
A. The resident's left side
B. The resident's right side
C. Directly in front of the resident
D. Behind the resident at all times
CORRECT ANSWER: B. The resident's right side
RATIONALE: When assisting a resident with one-sided weakness, the CNA should stand
on the affected side (right side in this case) to provide support and stability where it is
most needed. This positioning helps prevent falls and promotes safer mobility.
,Question 4: Which of the following is a sign of potential pressure injury
development that a CNA should report immediately?
A. Skin that is warm and pink
B. Skin that is cool and dry
C. Non-blanchable redness on a bony prominence
D. Skin that returns to normal color within 3 seconds after pressure is relieved
CORRECT ANSWER: C. Non-blanchable redness on a bony prominence
RATIONALE: Non-blanchable redness (redness that does not fade when pressure is
applied) on a bony area is an early sign of a Stage 1 pressure injury. Early recognition
and reporting allow for prompt intervention to prevent progression to more severe tissue
damage.
Question 5: When providing perineal care for a female resident, which technique
should the CNA use to minimize infection risk?
A. Wipe from back to front
B. Wipe from front to back
C. Use circular motions starting at the anus
D. Use the same area of the washcloth for multiple strokes
CORRECT ANSWER: B. Wipe from front to back
RATIONALE: Wiping from front to back prevents fecal bacteria from the anal area from
being introduced into the urethra or vagina, which significantly reduces the risk of
urinary tract infections and other complications.
Question 6: A resident's blood pressure reading is 150/92 mmHg. How should the
CNA document this finding?
A. Record it as normal since it is within acceptable limits
B. Report it immediately to the nurse as it indicates hypertension
C. Wait to see if it changes before documenting
D. Document only if the resident complains of symptoms
CORRECT ANSWER: B. Report it immediately to the nurse as it indicates
hypertension
RATIONALE: A blood pressure reading of 150/92 mmHg meets criteria for Stage 1
hypertension. CNAs must report abnormal vital signs promptly to the supervising nurse
for further assessment and potential intervention, regardless of whether symptoms are
present.
Question 7: Which principle of body mechanics should a CNA apply when lifting a
resident?
A. Bend at the waist to reach the resident
B. Keep feet close together for stability
, C. Use leg muscles rather than back muscles
D. Twist the torso while lifting to change direction
CORRECT ANSWER: C. Use leg muscles rather than back muscles
RATIONALE: Proper body mechanics require using the strong muscles of the legs and
maintaining a wide base of support to protect the caregiver's back. Bending at the waist,
keeping feet close together, or twisting while lifting increases the risk of
musculoskeletal injury.
Question 8: When making an occupied bed, what is the priority action for the CNA?
A. Change all linens as quickly as possible
B. Ensure the resident's privacy and safety throughout the procedure
C. Remove all pillows to make the task easier
D. Complete the task without explaining steps to the resident
CORRECT ANSWER: B. Ensure the resident's privacy and safety throughout the
procedure
RATIONALE: Resident dignity, privacy, and safety are paramount during all care
procedures. The CNA must explain steps, maintain privacy with curtains or doors, and
ensure the resident is secure and comfortable while minimizing exposure and fall risk.
Question 9: Which observation during oral care would require immediate reporting
to the nurse?
A. Resident prefers mint-flavored toothpaste
B. Resident has white, curd-like patches on the tongue that bleed when scraped
C. Resident brushes teeth slowly
D. Resident rinses mouth thoroughly after brushing
CORRECT ANSWER: B. Resident has white, curd-like patches on the tongue that
bleed when scraped
RATIONALE: White, curd-like patches that bleed when removed are classic signs of oral
candidiasis (thrush), a fungal infection requiring medical evaluation and treatment. This
finding should be reported promptly for appropriate intervention.
Question 10: A resident with dementia becomes agitated during bathing. What is
the most appropriate CNA response?
A. Restrain the resident to complete the bath quickly
B. Speak loudly to gain the resident's attention
C. Stop the procedure, reassure the resident, and try again later using a calm approach
D. Skip bathing for the day to avoid further agitation
CORRECT ANSWER: C. Stop the procedure, reassure the resident, and try again
later using a calm approach
