Question 1
Which class of medications is first-line therapy for the treatment of hypertension in a
patient with chronic kidney disease (CKD)?
A. Beta-blockers.
B. Calcium channel blockers.
C. Angiotensin-converting enzyme (ACE) inhibitors.
D. Thiazide diuretics.
Correct Answer:
C. Angiotensin-converting enzyme (ACE) inhibitors.
Rationale:
ACE inhibitors are recommended as first-line therapy in patients with CKD and hypertension
because they help reduce proteinuria and slow the progression of kidney disease by decreasing
intraglomerular pressure.
Question 2
What is the mechanism of action of metoprolol in the treatment of heart failure?
A. Blocks calcium channels in myocardial cells.
B. Stimulates beta-adrenergic receptors to increase heart rate.
C. Selectively blocks beta-1 adrenergic receptors to reduce myocardial workload.
D. Inhibits the renin-angiotensin-aldosterone system.
Correct Answer:
C. Selectively blocks beta-1 adrenergic receptors to reduce myocardial workload.
Rationale:
Metoprolol, a cardioselective beta-blocker, reduces myocardial oxygen demand and improves
left ventricular function by decreasing heart rate and contractility, making it effective for heart
failure management.
Question 3
,Which factor is a contraindication to the use of combined oral contraceptives (COCs)?
A. History of migraine without aura.
B. Aged 30 years and a smoker.
C. History of deep vein thrombosis (DVT).
D. BMI greater than 30.
Correct Answer:
C. History of deep vein thrombosis (DVT).
Rationale:
COCs increase the risk of thromboembolism, making them contraindicated in individuals with a
history of DVT.
Question 4
What is the primary action of sulfonylureas in the treatment of type 2 diabetes?
A. Enhances peripheral glucose uptake.
B. Increases insulin secretion from pancreatic beta cells.
C. Decreases hepatic glucose production.
D. Slows carbohydrate absorption in the intestines.
Correct Answer:
B. Increases insulin secretion from pancreatic beta cells.
Rationale:
Sulfonylureas, such as glipizide, stimulate pancreatic beta cells to release insulin, helping to
lower blood glucose levels in patients with type 2 diabetes.
Question 5
A patient with atrial fibrillation is prescribed warfarin. Which lab value should the nurse
practitioner monitor to evaluate the therapeutic effectiveness of the medication?
A. Platelet count.
B. Activated partial thromboplastin time (aPTT).
C. Prothrombin time (PT)/International Normalized Ratio (INR).
D. Bleeding time.
Correct Answer:
C. Prothrombin time (PT)/International Normalized Ratio (INR).
,Rationale:
The PT/INR is used to monitor warfarin therapy. A therapeutic INR range for atrial fibrillation is
typically 2.0–3.0 to prevent clot formation without increasing bleeding risk.
Question 6
What is a key adverse effect of amiodarone that requires regular monitoring?
A. Nephrotoxicity.
B. Pulmonary toxicity.
C. Hypoglycemia.
D. Hypercalcemia.
Correct Answer:
B. Pulmonary toxicity.
Rationale:
Amiodarone can cause severe pulmonary toxicity, including interstitial pneumonitis or fibrosis,
requiring regular monitoring with pulmonary function tests and chest X-rays.
Question 7
Which medication is the drug of choice for treating Clostridioides difficile infection?
A. Metronidazole (Flagyl).
B. Vancomycin (oral).
C. Ciprofloxacin.
D. Doxycycline.
Correct Answer:
B. Vancomycin (oral).
Rationale:
Oral vancomycin is preferred for moderate to severe C. difficile infections because it stays in the
gastrointestinal tract and effectively targets the infection site.
Question 8
Which medication is contraindicated in a patient with a history of angioedema caused by
ACE inhibitors?
A. Amlodipine.
B. Losartan.
, C. Hydrochlorothiazide.
D. Aliskiren.
Correct Answer:
D. Aliskiren.
Rationale:
Aliskiren, a direct renin inhibitor, can also cause angioedema and is contraindicated in patients
with a history of angioedema related to ACE inhibitors.
Question 9
What is the primary mechanism of action of statins like atorvastatin?
A. Inhibit cholesterol absorption in the intestines.
B. Stimulate hepatic LDL receptor production.
C. Inhibit the enzyme HMG-CoA reductase.
D. Increase HDL cholesterol levels.
Correct Answer:
C. Inhibit the enzyme HMG-CoA reductase.
Rationale:
Statins work by inhibiting HMG-CoA reductase, the rate-limiting enzyme in cholesterol
synthesis, leading to lower LDL cholesterol levels.
Question 10
Which of the following medications is used as first-line treatment for a patient with
generalized anxiety disorder (GAD)?
A. Diazepam (Valium).
B. Buspirone (Buspar).
C. Sertraline (Zoloft).
D. Propranolol.
Correct Answer:
C. Sertraline (Zoloft).
Rationale:
Selective serotonin reuptake inhibitors (SSRIs) like sertraline are the first-line treatment for
GAD because of their efficacy and safety profile compared to benzodiazepines or buspirone.
