HESI Practice Test Pharmacology Questions

Question 1 of 5

When planning to administer the antiulcer GI agent sucralfate, what instruction should the nurse provide regarding administration?

Correct Answer: D

Rationale: Sucralfate is most effective when taken on an empty stomach. This allows the medication to form a protective layer over the ulcer, promoting healing and symptom relief. Administering sucralfate with or after meals may reduce its efficacy as it may bind to food instead of coating the ulcer site.

Question 2 of 5

A client with a history of stroke is prescribed clopidogrel. The nurse should monitor for which potential side effect?

Correct Answer: A

Rationale: When a client with a history of stroke is prescribed clopidogrel, the nurse should monitor for potential side effects, especially bleeding. Clopidogrel is an antiplatelet medication that works by preventing blood clots. One of the major risks associated with clopidogrel is an increased tendency to bleed. Therefore, monitoring for signs of bleeding, such as easy bruising, blood in stool or urine, or prolonged bleeding from minor cuts, is crucial to ensure patient safety and early intervention if needed.

Question 3 of 5

A patient is prescribed sucralfate (Carafate) and asks the nurse what the purpose of taking this medication is. Which is the nurse's best response?

Correct Answer: C

Rationale: The correct answer is C. Sucralfate (Carafate) is used to protect the gastrointestinal mucosa by forming a protective barrier over ulcers. This barrier helps prevent stomach acid from further damaging the ulcers and promotes healing. It does not directly reduce bacteria levels, neutralize gastric acid, or have a direct effect on constipation.

Question 4 of 5

A client with hypertension is prescribed atenolol. The nurse should monitor for which potential side effect?

Correct Answer: A

Rationale: When a client is prescribed atenolol, a beta-blocker, the nurse should monitor for bradycardia, which is a potential side effect. Atenolol works by slowing the heart rate, so monitoring the client's heart rate is essential to detect and manage bradycardia promptly.

Question 5 of 5

The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

Correct Answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.
