,Q1. A patient with a history of chronic heart failure is prescribed a loop diuretic. Which laboratory
value is most critical to monitor to prevent a common adverse effect that could exacerbate the
underlying condition?
A. Serum sodium level
B. Serum potassium level
C. Serum creatinine level
D. Serum magnesium level
Correct Answer: B. Serum potassium level
Rationale: Loop diuretics commonly cause hypokalemia, which can lead to cardiac dysrhythmias and
worsen heart failure. Monitoring potassium is critical for preventing arrhythmias. Sodium, creatinine,
and magnesium are less directly linked to the immediate risk of exacerbation.
Why Wrong:
A - Hyponatremia can occur but does not directly exacerbate heart failure as rapidly as
hypokalemia-induced arrhythmias.
C - Serum creatinine monitors renal function, not a common adverse effect that exacerbates heart
failure.
D - Hypomagnesemia may occur but is not the most critical to monitor for acute exacerbation of
heart failure.

Q2. A patient with type 2 diabetes mellitus is started on metformin. Which mechanism of action best
explains why metformin is preferred over sulfonylureas in overweight patients?
A. Increases insulin secretion from pancreatic beta cells
B. Decreases hepatic glucose production and improves insulin sensitivity
C. Slows intestinal carbohydrate absorption
D. Inhibits renal glucose reabsorption
Correct Answer: B. Decreases hepatic glucose production and improves insulin sensitivity
Rationale: Metformin primarily decreases hepatic gluconeogenesis and enhances peripheral insulin
sensitivity without stimulating insulin secretion, thus does not cause weight gain. Sulfonylureas increase
insulin secretion, often leading to weight gain. Option A describes sulfonylureas; C is acarbose; D is
SGLT2 inhibitors.
Why Wrong:
A - This is the mechanism of sulfonylureas, which can cause weight gain.
C - This is the mechanism of alpha-glucosidase inhibitors, not metformin.
D - This is the mechanism of SGLT2 inhibitors, not metformin.

, Q3. A patient receiving morphine via patient-controlled analgesia (PCA) has a respiratory rate of 8
breaths per minute. Which intervention should the nurse prioritize?
A. Administer naloxone 0.4 mg intravenously
B. Increase the PCA basal rate to relieve pain
C. Stimulate the patient to breathe deeply
D. Discontinue the PCA and administer oxygen
Correct Answer: A. Administer naloxone 0.4 mg intravenously
Rationale: Respiratory depression (rate <10/min) from opioid overdose requires immediate reversal with
naloxone. Increasing the PCA rate would worsen depression. Stimulation is temporary. Discontinuing
PCA and oxygen alone does not reverse the opioid effect. Naloxone is the antidote.
Why Wrong:
B - Increasing opioid dose would worsen respiratory depression.
C - Stimulation is only a temporary measure and does not reverse opioid effects.
D - Oxygen alone does not reverse opioid-induced respiratory depression; naloxone is needed.

Q4. A patient with atrial fibrillation is being discharged on warfarin. Which dietary instruction is
most important to prevent loss of therapeutic effect?
A. Avoid foods high in vitamin K, such as leafy green vegetables
B. Increase intake of foods rich in vitamin C
C. Limit consumption of dairy products
D. Avoid foods containing tyramine
Correct Answer: A. Avoid foods high in vitamin K, such as leafy green vegetables
Rationale: Vitamin K antagonizes warfarin's effect. Consistent intake of vitamin K is key; abrupt
increases can reduce INR. Patients should maintain a consistent diet of vitamin K-rich foods, not avoid
them entirely, but the question asks to prevent loss of effect, so avoiding high intake is correct. Vitamin C
and tyramine are not relevant. Dairy is not a primary concern.
Why Wrong:
B - Vitamin C does not significantly affect warfarin metabolism.
C - Dairy products do not directly interfere with warfarin.
D - Tyramine restriction is for MAO inhibitors, not warfarin.
