Question 1
A patient with heart failure is prescribed
furosemide. Which laboratory value is most
important to monitor?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum magnesium
Correct Answer: B
Rationale: Furosemide is a loop diuretic that can
,cause significant potassium loss, leading to
hypokalemia. Monitoring serum potassium is
essential to prevent cardiac arrhythmias and other
complications.
Question 2
A nurse is caring for a patient with diabetic
ketoacidosis. Which finding indicates that treatment
is effective?
A. Serum glucose decreased to 250 mg/dL
B. Serum bicarbonate increased to 20 mEq/L
C. Serum potassium decreased to 3.5 mEq/L
D. Arterial pH decreased to 7.20
Correct Answer: B
Rationale: An increase in serum bicarbonate
toward normal (22-26 mEq/L) indicates that
metabolic acidosis is resolving, which is a key goal
in DKA treatment.
Question 3
Which clinical manifestation is most indicative of
anaphylactic shock?
A. Hypertension and bradycardia
,B. Urticaria and stridor
C. Hyperglycemia and polyuria
D. Fever and chills
Correct Answer: B
Rationale: Urticaria (hives) and stridor (upper
airway narrowing) are hallmark signs of
anaphylaxis. These result from massive histamine
release and require immediate intervention.
Question 4
A patient post-myocardial infarction is prescribed
aspirin. What is the primary purpose of this
medication?
A. To reduce fever
B. To prevent platelet aggregation
C. To decrease cardiac workload
D. To relieve chest pain
Correct Answer: B
Rationale: Aspirin inhibits cyclooxygenase-1,
reducing thromboxane A2 production and
preventing platelet aggregation, which reduces the
risk of further thrombotic events.
, Question 5
A nurse is teaching a patient with COPD about
pursed-lip breathing. What is the main benefit of
this technique?
A. Increases oxygen intake
B. Prevents alveolar collapse
C. Reduces respiratory rate
D. Improves carbon dioxide elimination
Correct Answer: D
Rationale: Pursed-lip breathing creates positive
pressure in the airways, preventing premature
airway collapse and improving CO2 elimination in
patients with COPD.
Question 6
Which finding in a newborn is most suggestive of
respiratory distress syndrome?
A. Acrocyanosis
B. Grunting respirations
C. Periodic breathing
D. Nasal flaring
Correct Answer: B
Rationale: Grunting respirations occur when the
