1. A patient is scheduled for a CT scan with intravenous contrast. Which
medication must be held for 48 hours after the procedure to prevent lactic
acidosis?
A. Metformin
B. Glyburide
C. Pioglitazone
D. Sitagliptin
Answer: A
Rationale: Metformin must be withheld 48 hours after contrast media administration to
avoid the risk of acute renal failure and subsequent lactic acidosis.
2. When is the best time for a patient to take Levothyroxine for the treatment of
hypothyroidism?
A. Immediately after a large meal
B. 30 to 60 minutes before breakfast on an empty stomach
C. At bedtime with a snack
D. With lunch to increase absorption
Answer: B
Rationale: Levothyroxine should be taken on an empty stomach, usually 30-60 minutes

,3. Which instruction is critical for a patient taking Alendronate for osteoporosis?
A. Sit or stand upright for at least 30 minutes after administration
B. Lie down for 30 minutes after taking the pill
C. Take with a full glass of milk
D. Take the medication right before going to bed
Answer: A
Rationale: Patients must remain upright for 30 minutes to prevent esophageal irritation
and ulceration associated with bisphosphonates.
4. A patient taking Sildenafil for erectile dysfunction should be warned against
using which class of medications?
A. Beta-blockers
B. Nitrates
C. Proton pump inhibitors
D. NSAIDs
Answer: B
Rationale: The combination of Sildenafil and Nitrates can cause life-threatening
hypotension.
5. Which type of insulin has the fastest onset of action, typically within 15
minutes?
A. Insulin Glargine
B. Regular Insulin
C. NPH Insulin
D. Insulin Lispro
Answer: D
Rationale: Insulin Lispro is a rapid-acting insulin with an onset of 15 to 30 minutes.
, 6. What is the first-line emergency treatment for a severe hypoglycemic
reaction in an unconscious patient without IV access?
A. Subcutaneous Glucagon
B. Intravenous D50W
C. Oral glucose gel
D. A glass of orange juice
Answer: A
Rationale: If a patient is unconscious and no IV access is available, Glucagon is
administered IM or SubQ to stimulate glucose release.
7. Long-term use of high-dose Prednisone is most likely to cause which of the
following side effects?
A. Hypoglycemia
B. Weight loss
C. Hyperglycemia and Moon face
D. Low blood pressure
Answer: C
Rationale: Cushingoid features such as moon face and hyperglycemia are classic side
effects of long-term glucocorticoid use.
8. A patient taking Methimazole for hyperthyroidism should be monitored for
which life-threatening adverse effect?
A. Constipation
B. Tachycardia
C. Hypertension
D. Agranulocytosis
Answer: D
Rationale: Methimazole can cause agranulocytosis (a dangerous drop in white blood cell
count); patients should report fever or sore throat immediately.
