1. A nurse is assessing a patient with dehydration. Which finding is
most consistent with this condition?
A. Bradycardia
B. Dry mucous membranes
C. Increased urine output
D. Bounding pulses
Answer: B
Rationale: Dehydration leads to decreased fluid volume, resulting
in dry mucous membranes, poor skin turgor, tachycardia, and
concentrated urine.
2. Which electrolyte imbalance is most associated with muscle
weakness and cardiac dysrhythmias?
A. Hypernatremia
B. Hypokalemia
C. Hypercalcemia
, D. Hypermagnesemia
Answer: B
Rationale: Potassium is essential for muscle and cardiac function;
low potassium causes weakness and arrhythmias.
3. A patient is receiving oxygen via nasal cannula. What is the
correct flow rate range for this device?
A. 1–6 L/min
B. 7–10 L/min
C. 10–15 L/min
D. 0–1 L/min
Answer: A
Rationale: Nasal cannula delivers low-flow oxygen typically
between 1–6 L/min.
4. What is the priority action when a patient begins to choke and
cannot speak?
A. Encourage coughing
B. Perform abdominal thrusts
C. Give water
D. Perform back massage
, Answer: B
Rationale: Complete airway obstruction requires immediate
abdominal thrusts (Heimlich maneuver).
5. Which vital sign change indicates early shock?
A. Hypertension
B. Bradycardia
C. Tachycardia
D. Increased oxygen saturation
Answer: C
Rationale: Tachycardia is an early compensatory response to
maintain cardiac output in shock.
6. Which acid-base imbalance is characterized by deep, rapid
breathing?
A. Respiratory acidosis
B. Metabolic alkalosis
C. Respiratory alkalosis
D. Metabolic acidosis
Answer: D
, Rationale: Kussmaul respirations occur in metabolic acidosis as the
body tries to blow off CO₂.
7. A nurse is caring for a patient with heart failure. Which diet
modification is most appropriate?
A. High sodium diet
B. Fluid restriction
C. High potassium diet
D. High carbohydrate diet
Answer: B
Rationale: Fluid restriction helps prevent fluid overload in heart
failure.
8. What is the normal adult respiratory rate?
A. 6–10 breaths/min
B. 10–12 breaths/min
C. 12–20 breaths/min
D. 20–30 breaths/min
Answer: C
Rationale: Normal adult respiratory rate is 12–20 breaths per
minute.
