Question 1
A client with heart failure is prescribed furosemide.
Which laboratory value should the nurse monitor
most closely?
A) Serum sodium
B) Serum potassium
C) Serum calcium
D) Serum magnesium
Correct Answer: B. Serum potassium
Rationale: Furosemide is a loop diuretic that causes
excessive potassium excretion in the distal tubule.
Hypokalemia can lead to cardiac arrhythmias,
especially in clients taking digoxin. The nurse should
,monitor serum potassium levels closely and report
levels below 3.5 mEq/L.
Question 2
A client with diabetes mellitus type 2 is admitted
with hyperglycemic hyperosmolar syndrome (HHS).
Which finding is most consistent with this
condition?
A) Kussmaul respirations
B) Serum glucose of 800 mg/dL
C) Serum ketones positive
D) Arterial pH of 7.28
Correct Answer: B. Serum glucose of 800 mg/dL
Rationale: HHS is characterized by extreme
hyperglycemia (often >600 mg/dL),
hyperosmolarity, and severe dehydration without
significant ketosis or acidosis. Kussmaul respirations
and low pH are seen in diabetic ketoacidosis (DKA),
not HHS.
Question 3
A postoperative client reports sudden chest pain
and dyspnea. The nurse notes tachycardia and
,hypotension. What is the priority action?
A) Administer oxygen
B) Notify the healthcare provider
C) Place the client in a high-Fowler’s position
D) Assess the surgical site
Correct Answer: A. Administer oxygen
Rationale: The client is exhibiting signs of a
pulmonary embolism. The priority action is to
administer high-flow oxygen to maintain
oxygenation. After stabilizing the airway and
breathing, the nurse should notify the provider and
prepare for further interventions.
Question 4
A client with cirrhosis has ascites and is receiving
spironolactone. Which finding indicates the
medication is effective?
A) Decreased abdominal girth
B) Increased serum sodium
C) Decreased urine output
D) Increased peripheral edema
Correct Answer: A. Decreased abdominal girth
Rationale: Spironolactone is a potassium-sparing
, diuretic used to manage ascites. A decrease in
abdominal girth indicates a reduction in fluid
accumulation, demonstrating therapeutic
effectiveness. The nurse should also monitor for
hyperkalemia.
Question 5
A nurse is caring for a client on mechanical
ventilation. Which intervention is most important to
prevent ventilator-associated pneumonia (VAP)?
A) Suction the client every 2 hours
B) Elevate the head of the bed to 30-45 degrees
C) Change the ventilator circuit daily
D) Administer prophylactic antibiotics
Correct Answer: B. Elevate the head of the bed to
30-45 degrees
Rationale: Elevating the head of the bed to 30-45
degrees reduces the risk of aspiration and VAP. This
is a core component of the VAP prevention bundle.
Routine circuit changes are not recommended daily,
and antibiotics are not given prophylactically for
VAP.
