HESI Practice Test Pharmacology

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.

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.

Correct Answer: A

Rationale: The correct answer is A: Liver toxicity. Methotrexate is known to cause liver toxicity, making regular monitoring of liver function essential. Monitoring liver function tests helps detect any signs of liver damage early, allowing for appropriate interventions to be implemented promptly.

Correct Answer: C

Rationale: The correct answer is to allow a 15-minute interval between the administration of cyclosporine and artificial tears. Cyclosporine, an ophthalmic emulsion that increases tear production, can be used in conjunction with artificial tears as long as the products are administered 15 minutes apart. This interval helps to prevent any potential interactions between the two products and ensures optimal effectiveness of cyclosporine for treating dry eyes.

Correct Answer: A

Rationale: Carbamazepine is associated with the potential adverse effect of agranulocytosis, a serious condition characterized by a low white blood cell count. Monitoring white blood cell counts regularly is crucial to detect this adverse effect early and prevent complications.
