Question 1:
Which of the following is the primary action of beta-blockers?
A) Increase heart rate
B) Decrease blood pressure
C) Dilate blood vessels
D) Increase myocardial contractility
Answer: B) Decrease blood pressure
Rationale: Beta-blockers primarily work by blocking beta-adrenergic receptors,
which decreases heart rate and myocardial contractility, ultimately reducing blood
pressure.
Question 2:
Which class of drugs is used to treat hypertension by inhibiting the renin-
angiotensin-aldosterone system?
A) ACE inhibitors
B) Beta-blockers
C) Calcium channel blockers
D) Diuretics
Answer: A) ACE inhibitors
Rationale: ACE inhibitors block the enzyme that converts angiotensin I to
angiotensin II, a powerful vasoconstrictor. This action helps in lowering blood
pressure.
Question 3:
A nurse is caring for a patient who is prescribed digoxin. What is the most
important monitoring parameter for digoxin therapy?
A) Blood glucose levels
B) Heart rate
C) Liver function tests
D) Serum potassium levels
,Answer: B) Heart rate
Rationale: Digoxin can cause bradycardia. It’s important to monitor the heart rate
regularly to ensure it doesn't drop too low, which could lead to adverse effects like
arrhythmias.
Question 4:
What is the common side effect of opioid analgesics?
A) Diarrhea
B) Constipation
C) Weight loss
D) Insomnia
Answer: B) Constipation
Rationale: Opioids, such as morphine, frequently cause constipation due to their
action on the gastrointestinal system, slowing motility.
Question 5:
Which of the following is an adverse effect of nonsteroidal anti-inflammatory
drugs (NSAIDs)?
A) Hypertension
B) Gastric ulceration
C) Hypoglycemia
D) Hyperkalemia
Answer: B) Gastric ulceration
Rationale: NSAIDs can inhibit prostaglandin synthesis, which protects the stomach
lining. This inhibition can lead to gastric ulcers and bleeding.
Question 6:
Which medication is used to reverse the effects of opioid overdose?
A) Naloxone
, B) Acetaminophen
C) Flumazenil
D) Atropine
Answer: A) Naloxone
Rationale: Naloxone is an opioid antagonist used to rapidly reverse the effects of
opioid overdose, including respiratory depression.
Question 7:
Which of the following is a contraindication for the use of thiazide diuretics?
A) Hypokalemia
B) Pregnancy
C) Renal failure
D) Hypercalcemia
Answer: C) Renal failure
Rationale: Thiazide diuretics are contraindicated in patients with renal failure
because they are not effective when renal function is significantly impaired.
Question 8:
A patient is prescribed warfarin. Which laboratory test should be monitored to
assess the therapeutic effectiveness of warfarin?
A) Prothrombin time (PT)/International Normalized Ratio (INR)
B) Platelet count
C) Hemoglobin level
D) Activated partial thromboplastin time (aPTT)
Answer: A) Prothrombin time (PT)/International Normalized Ratio (INR)
Rationale: Warfarin is an anticoagulant, and its effectiveness is monitored through
PT/INR to ensure proper dosing and minimize the risk of bleeding.
Question 9:
Which of the following is the primary action of beta-blockers?
A) Increase heart rate
B) Decrease blood pressure
C) Dilate blood vessels
D) Increase myocardial contractility
Answer: B) Decrease blood pressure
Rationale: Beta-blockers primarily work by blocking beta-adrenergic receptors,
which decreases heart rate and myocardial contractility, ultimately reducing blood
