Q1.
A patient with type 2 diabetes is prescribed metformin 500 mg twice daily. The patient is
scheduled for a CT scan with IV contrast. What is the most appropriate nursing action?
A. Administer metformin as prescribed and B. Hold metformin on the day of the
monitor blood glucose. procedure and for 48 hours after.
C. Give metformin with a small meal before D. Switch to insulin for 24 hours before the
the procedure. procedure.
Correct: B - Hold metformin on the day of the procedure and for 48 hours after.
Rationale:Metformin should be withheld on the day of contrast administration and for 48
hours afterward due to the risk of contrast-induced nephropathy and lactic acidosis. Renal
function should be re-evaluated before resuming. Administering it or switching to insulin is
unnecessary and potentially harmful.
Why the other answers are wrong:
A. Administering metformin with contrast increases the risk of lactic acidosis, especially if renal
function is compromised.
C. Giving metformin with a meal does not mitigate the risk of contrast-induced nephropathy.
D. Switching to insulin is not required; holding metformin is sufficient.

Q2.
A patient with chronic kidney disease (CKD) and hyperkalemia is prescribed sodium
polystyrene sulfonate (Kayexalate). Which assessment finding indicates a need to
discontinue the medication?
A. Serum potassium level of 4.5 mEq/L B. Bowel obstruction with abdominal
distention
C. Serum sodium level of 135 mEq/L D. Blood glucose level of 110 mg/dL
Correct: B - Bowel obstruction with abdominal distention
Rationale:Sodium polystyrene sulfonate can cause intestinal necrosis and bowel obstruction;
the development of obstructive symptoms warrants immediate discontinuation. A normal
potassium level is the therapeutic goal, and mild hyponatremia may be managed, but bowel
obstruction is a severe adverse effect.
Why the other answers are wrong:
A. A potassium level of 4.5 mEq/L indicates effective treatment, not a reason to stop.
C. Mild hyponatremia is a potential side effect but not a contraindication; it can be monitored.

D. Blood glucose is unrelated to this medication's adverse effects.

Q3.
A nurse is reviewing laboratory results for a patient with suspected preeclampsia. Which
finding is most consistent with severe preeclampsia?
A. Platelet count 150,000/mm³ B. Serum creatinine 1.0 mg/dL
C. Aspartate aminotransferase (AST) 80 U/L D. Urine protein 2+ on dipstick
Correct: C - Aspartate aminotransferase (AST) 80 U/L
Rationale:Elevated liver enzymes (AST > 70 U/L) indicate hepatic dysfunction, a criterion for
severe preeclampsia. Thrombocytopenia (<100,000), elevated creatinine (>1.1 mg/dL), and
significant proteinuria (3+) are also signs, but a platelet count of 150,000, creatinine 1.0, and
2+ protein are not severe.
Why the other answers are wrong:
A. A platelet count of 150,000 is within normal limits and not indicative of severe preeclampsia.
B. A serum creatinine of 1.0 mg/dL is normal and does not meet severe criteria.
D. 2+ protein on dipstick is moderate but not severe; severe is 3+ or more.

Q4.
A patient with schizophrenia is prescribed clozapine. Which statement indicates the need
for immediate intervention?
A. I have been feeling more energetic lately. B. I have a sore throat and fever.
C. I sometimes feel dizzy when I stand up. D. I have gained about 5 pounds in the last
month.
Correct: B - I have a sore throat and fever.
Rationale:Clozapine can cause agranulocytosis, and a sore throat with fever may indicate
infection due to neutropenia. Immediate blood count is needed. Dizziness from orthostatic
hypotension and weight gain are common but not emergent; increased energy is not typical
adverse effect.
Why the other answers are wrong:
A. Increased energy is not a recognized warning sign for clozapine adverse effects.
C. Dizziness on standing is a common side effect but not immediately dangerous.
D. Weight gain is a common metabolic side effect but not an emergency.
