1. A nurse is caring for a client with dehydration. Which
assessment finding is most concerning?
A. Moist mucous membranes
B. Urine output of 20 mL/hr
C. Heart rate of 78 bpm
D. Blood pressure of 120/80 mmHg
Correct Answer: B. Urine output of 20 mL/hr
Rationale: Low urine output is an early sign of inadequate
kidney perfusion and severe dehydration. A urine output less
than 30 mL/hr in adults requires prompt intervention.
2. Which electrolyte imbalance is most commonly associated
with muscle weakness and cardiac dysrhythmias?
A. Hypercalcemia
B. Hyponatremia
C. Hypokalemia
D. Hypermagnesemia
Correct Answer: C. Hypokalemia
Rationale: Potassium is essential for neuromuscular and
cardiac function. Low potassium levels can cause muscle
weakness, arrhythmias, and ECG changes.
,3. A nurse is teaching a client about insulin administration.
Which instruction is correct?
A. Inject insulin into the same site daily
B. Shake cloudy insulin vigorously
C. Rotate injection sites within the same anatomical area
D. Store opened insulin in the freezer
Correct Answer: C. Rotate injection sites within the same
anatomical area
Rationale: Rotating sites within the same anatomical area helps
maintain consistent absorption while preventing lipodystrophy.
4. Which client is at greatest risk for pressure injuries?
A. Ambulatory client with hypertension
B. Client on prolonged bed rest
C. Postoperative client walking independently
D. Young adult with seasonal allergies
Correct Answer: B. Client on prolonged bed rest
Rationale: Immobility increases pressure over bony
prominences, reducing blood flow and increasing risk for skin
breakdown.
,5. A nurse should place a client experiencing dyspnea in
which position?
A. Supine
B. Trendelenburg
C. High Fowler’s
D. Prone
Correct Answer: C. High Fowler’s
Rationale: High Fowler’s position maximizes lung expansion
and improves oxygenation in clients with breathing difficulties.
6. Which finding indicates effective pain management?
A. Client sleeps continuously
B. Respiratory rate decreases to 8/min
C. Client reports pain decreased from 8/10 to 3/10
D. Blood pressure rises significantly
Correct Answer: C. Client reports pain decreased from 8/10 to
3/10
Rationale: Pain is subjective, and the client’s report is the most
reliable indicator of pain relief.
7. A nurse is caring for a client with hypoglycemia. Which
intervention should be performed first?
, A. Administer insulin
B. Give 15 g of fast-acting carbohydrates
C. Restrict fluids
D. Encourage exercise
Correct Answer: B. Give 15 g of fast-acting carbohydrates
Rationale: Immediate treatment of hypoglycemia includes rapid
administration of glucose to restore blood sugar levels.
8. Which assessment finding suggests infection?
A. Temperature of 39°C (102.2°F)
B. Heart rate of 60 bpm
C. Blood glucose of 90 mg/dL
D. Oxygen saturation of 98%
Correct Answer: A. Temperature of 39°C (102.2°F)
Rationale: Fever is a common sign of infection due to the body’s
inflammatory response.
9. A nurse is teaching hand hygiene. Which statement by the
client indicates understanding?
A. “I only wash my hands when visibly dirty.”
B. “Alcohol-based rubs are effective when hands are not visibly
soiled.”
C. “Gloves replace handwashing.”
D. “Hot water is required for hand hygiene.”
