Q1. A nursing assistant enters a resident's room to provide morning care. What is the
FIRST step the NA should take before any patient contact?
A. Gather all necessary supplies
B. Perform hand hygiene
C. Introduce self to the resident
D. Check the resident's care plan
Correct Answer: B
B. Perform hand hygiene [CORRECT]
Rationale: Hand hygiene is the first step before any resident contact per CDC and
facility infection control protocols. A is incorrect because supplies are gathered after
hand hygiene. C is incorrect because introduction occurs after hand hygiene at the
bedside. D is incorrect because the care plan is reviewed before entering the room,
not as the first action upon entry. CNA Pearl: Hand hygiene is always the first and
last step of every procedure. The 5 moments of hand hygiene begin with "before
touching a resident."
,Q2. When measuring an adult's oral temperature, the nursing assistant should place
the thermometer:
A. Under the tongue in the posterior sublingual pocket
B. Under the tongue in the anterior sublingual pocket
C. Between the cheek and gum
D. On top of the tongue
Correct Answer: A
A. Under the tongue in the posterior sublingual pocket [CORRECT]
Rationale: The thermometer probe is placed in the posterior sublingual pocket
(either side of the frenulum) where the sublingual artery provides accurate core
temperature measurement. B is incorrect because the anterior pocket is too close to
the mouth opening and affected by ambient air. C is incorrect because the cheek and
gum placement measures buccal temperature, not oral. D is incorrect because
placing on top of the tongue yields inaccurate readings. CNA Pearl: Posterior
sublingual pocket = most accurate oral site. Wait 15-20 minutes after smoking,
hot/cold beverages, or chewing gum before oral temperature.
Q3. A nursing assistant is measuring a resident's radial pulse. The pulse is irregular.
How long should the NA count the pulse?
A. 15 seconds and multiply by 4
B. 30 seconds and multiply by 2
C. 60 seconds (full minute)
D. 10 seconds and multiply by 6
Correct Answer: C
C. 60 seconds (full minute) [CORRECT]
Rationale: An irregular pulse requires a full 60-second count to accurately assess
rate and rhythm irregularities. A, B, and D are incorrect because abbreviated counts
are only acceptable for regular pulses and would miss irregularities. CNA Pearl: Full
minute pulse count is required for: irregular pulses, apical pulses, pediatric patients,
,and residents on cardiac/dysrhythmia medications. Regular adult radial pulses may
be counted for 30 seconds × 2.
Q4. When measuring blood pressure, the nursing assistant notices the cuff bladder
width is only 30% of the arm circumference. How will this affect the reading?
A. It will produce a falsely low reading
B. It will produce a falsely high reading
C. It will not affect the reading
D. It will produce an accurate reading
Correct Answer: B
B. It will produce a falsely high reading [CORRECT]
Rationale: A cuff that is too narrow (less than 40% of arm circumference) produces a
falsely elevated blood pressure reading because the bladder cannot fully occlude the
brachial artery. A is incorrect because a cuff that is too large produces falsely low
readings. C and D are incorrect because improper cuff size always affects accuracy.
CNA Pearl: Cuff sizing rule: bladder width = 40% of arm circumference, length = 80%
of arm circumference. Too small = falsely HIGH. Too large = falsely LOW.
Q5. A resident is on strict intake and output (I&O) measurement. The nursing
assistant measures the following: oral fluids 1,200mL, IV fluids 500mL, urine output
1,800mL, emesis 200mL. What is the resident's net fluid balance?
A. +200mL
B. -100mL
C. -300mL
D. +1,500mL
Correct Answer: C
C. -300mL [CORRECT]
, Rationale: Total intake = 1,200mL + 500mL = 1,700mL. Total output = 1,800mL +
200mL = 2,000mL. Net balance = 1,700mL - 2,000mL = -300mL (negative balance
indicates more output than intake). A is incorrect because it ignores emesis. B is
incorrect due to calculation error. D is incorrect because it adds instead of subtracts.
CNA Pearl: Net fluid balance = Total Intake - Total Output. Negative = output
exceeds intake (dehydration risk). Positive = intake exceeds output (fluid overload
risk). Report significant imbalances to the nurse.
Q6. The nursing assistant is repositioning a resident who is on bedrest. The resident
has a Stage 2 pressure injury on the right heel. Which positioning technique is MOST
appropriate?
A. Place a pillow under the calf with the heel floating free of the bed surface
B. Place the resident in supine position with heels resting on the mattress
C. Elevate the foot of the bed 30 degrees to reduce heel pressure
D. Apply a heating pad to the heel to improve circulation
Correct Answer: A
A. Place a pillow under the calf with the heel floating free of the bed surface
[CORRECT]
Rationale: Heel offloading requires the heel to be suspended above the mattress
surface using a pillow placed under the calf (not under the heel). B is incorrect
because resting heels on the mattress creates pressure. C is incorrect because
elevating the foot of the bed increases shear forces on the sacrum and does not
address heel pressure. D is incorrect because heating pads are contraindicated on
pressure injuries and can cause burns. CNA Pearl: Heel suspension = pillow under
calf, heel free. Never place pillows directly under the heel—this creates pressure on
the Achilles tendon.
Q7. A resident requires passive range of motion (PROM) exercises for the right
shoulder. The nursing assistant should:
