Care & State Nurse Aide Exam Prep
Question 1: When assisting a resident with ambulation, what is the MOST
important action for the CNA to take to ensure safety?
A. Walk slightly behind the resident to provide support
B. Hold the resident's arm tightly to prevent falling
C. Use a gait belt and walk on the resident's weaker side
D. Allow the resident to lean on furniture for support
CORRECT ANSWER: C. Use a gait belt and walk on the resident's weaker side
Rationale: : Using a gait belt provides secure support while allowing the resident
independence, and positioning on the weaker side enables the CNA to offer immediate
assistance if balance is lost. This technique follows standard safety protocols for
ambulation assistance and reduces fall risk while promoting resident mobility.
Question 2: Which of the following is the FIRST step a CNA should take when
discovering a resident has fallen?
A. Help the resident stand up immediately
B. Call for help and assess the resident's condition
C. Document the incident in the resident's chart
D. Notify the family member on file
CORRECT ANSWER: B. Call for help and assess the resident's condition
Rationale: : Safety and assessment take priority after a fall. The CNA must first ensure
help is available and evaluate the resident for injuries before attempting to move them.
Moving a resident without assessment could worsen injuries such as fractures or spinal
damage.
Question 3: What is the proper technique for performing hand hygiene when hands
are NOT visibly soiled?
A. Wash with soap and water for at least 10 seconds
B. Use an alcohol-based hand rub for at least 20 seconds
C. Wipe hands with a disinfectant towel
D. Rinse hands under warm water only
CORRECT ANSWER: B. Use an alcohol-based hand rub for at least 20 seconds
,Rationale: : According to CDC guidelines, alcohol-based hand rubs are effective for
routine hand hygiene when hands are not visibly dirty. The rub should be applied to all
surfaces of hands and rubbed until dry, which typically takes 20 seconds. Soap and
water are reserved for visibly soiled hands or after caring for patients with certain
infections like C. diff.
Question 4: A resident with dementia becomes agitated during bathing. What is the
BEST approach for the CNA?
A. Complete the bath quickly to minimize distress
B. Stop the bath and report the behavior to the nurse
C. Speak calmly, explain each step, and offer choices when possible
D. Restrain the resident gently to ensure safety
CORRECT ANSWER: C. Speak calmly, explain each step, and offer choices when
possible
Rationale: : Person-centered care for residents with dementia involves reducing
triggers, using clear communication, and maintaining dignity. Offering simple choices
and explaining procedures can decrease agitation. Restraints are never appropriate for
convenience, and stopping care entirely may compromise hygiene without addressing
the underlying cause.
Question 5: Which vital sign measurement requires the CNA to place the
stethoscope over the brachial artery?
A. Apical pulse
B. Blood pressure
C. Respiratory rate
D. Temperature
CORRECT ANSWER: B. Blood pressure
Rationale: : Blood pressure is measured using a sphygmomanometer and stethoscope
placed over the brachial artery in the antecubital space. The CNA inflates the cuff and
listens for Korotkoff sounds to determine systolic and diastolic pressures. Apical pulse
requires placement over the heart's apex, not the brachial artery.
Question 6: When measuring a resident's oral temperature, which action is
INCORRECT?
A. Place the thermometer under the tongue in the posterior sublingual pocket
B. Ask the resident to keep lips closed around the thermometer
C. Take the temperature immediately after the resident drinks hot coffee
D. Wait 15-30 minutes after eating or drinking before taking an oral temperature
CORRECT ANSWER: C. Take the temperature immediately after the resident drinks
hot coffee
,Rationale: : Consuming hot or cold substances can temporarily alter oral temperature
readings, leading to inaccurate results. CNAs should wait 15-30 minutes after eating,
drinking, or smoking before obtaining an oral temperature to ensure accuracy.
Question 7: Which of the following is a sign of dehydration in an elderly resident?
A. Increased skin turgor
B. Moist mucous membranes
C. Dark, concentrated urine
D. Elevated blood pressure
CORRECT ANSWER: C. Dark, concentrated urine
Rationale: : Dark, concentrated urine is a classic indicator of dehydration, as the
kidneys conserve water when fluid intake is inadequate. Other signs include decreased
skin turgor, dry mucous membranes, confusion, and low blood pressure. CNAs should
report these findings promptly.
Question 8: What is the PRIMARY purpose of using proper body mechanics when
lifting or moving a resident?
A. To complete tasks more quickly
B. To prevent injury to both the CNA and the resident
C. To reduce the need for assistive devices
D. To comply with documentation requirements
CORRECT ANSWER: B. To prevent injury to both the CNA and the resident
Rationale: : Proper body mechanics—including keeping the back straight, bending at
the knees, and using leg muscles—protect the CNA from musculoskeletal injuries and
ensure safe, stable movement of residents. This is a foundational safety principle in
nursing assistant practice.
Question 9: Which resident right is protected under the Omnibus Budget
Reconciliation Act (OBRA)?
A. The right to choose meal times
B. The right to be free from unnecessary restraints
C. The right to select their roommate
D. The right to refuse all medications without discussion
CORRECT ANSWER: B. The right to be free from unnecessary restraints
Rationale: : OBRA established federal standards for nursing home care, including
residents' rights to dignity, autonomy, and freedom from physical or chemical restraints
unless medically necessary and ordered by a physician. CNAs must uphold these rights
in daily care.
Question 10: When providing perineal care for a female resident, which direction
should the CNA clean to prevent infection?
, A. From back to front
B. In a circular motion around the urethra
C. From front to back
D. From side to side across the perineum
CORRECT ANSWER: C. From front to back
Rationale: : Cleaning from front to back prevents fecal bacteria from the anal area from
being introduced into the urethra or vagina, reducing the risk of urinary tract infections.
This technique is essential for maintaining hygiene and preventing infection in female
residents.
Question 11: A resident's pulse is measured at 110 beats per minute. This finding is
documented as:
A. Bradycardia
B. Tachycardia
C. Arrhythmia
D. Hypertension
CORRECT ANSWER: B. Tachycardia
Rationale: : Tachycardia is defined as a heart rate exceeding 100 beats per minute in
adults. Bradycardia refers to a rate below 60 bpm. Arrhythmia indicates an irregular
rhythm, and hypertension relates to blood pressure, not pulse rate. CNAs must
recognize and report abnormal vital signs.
Question 12: Which of the following is the MOST appropriate action when a resident
refuses care?
A. Insist on providing care because it is required
B. Document the refusal and notify the nurse
C. Skip the care and move to the next resident
D. Report the resident for noncompliance
CORRECT ANSWER: B. Document the refusal and notify the nurse
Rationale: : Residents have the right to refuse care. The CNA must respect this
decision, document the refusal accurately, and inform the nurse so alternative
approaches or assessments can be considered. Forcing care violates resident rights
and may constitute abuse.
Question 13: What is the correct sequence for donning personal protective
equipment (PPE) before entering a resident's room?
A. Gloves, gown, mask, goggles
B. Gown, mask, goggles, gloves
C. Mask, goggles, gown, gloves
D. Goggles, gloves, gown, mask
