Pharmacology HESI 55 Questions 2023

1. A practical nurse (PN) is reviewing teaching with the client and/or significant others about the concurrent use of benztropine and olanzapine to manage psychotic behavior. What information should the PN reinforce?

Correct answer: C

Rationale: The correct answer is C because benztropine, an anticholinergic drug, is used to control extrapyramidal symptoms associated with olanzapine use. Choice A is incorrect because benztropine does not directly reduce olanzapine's side effect of urinary retention. Choice B is incorrect as benztropine does not potentiate the effect of olanzapine; its main role is to counteract extrapyramidal symptoms. Choice D is incorrect because the primary purpose of using benztropine alongside olanzapine is to manage side effects, not specifically to modify psychotic behavior.

2. 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.

3. A client with severe rheumatoid arthritis is prescribed methotrexate. The nurse should monitor the client for which potential adverse effect?

Correct answer: A

Rationale: The correct answer is A: Bone marrow suppression. Methotrexate, commonly used in rheumatoid arthritis, can lead to bone marrow suppression, reducing the production of blood cells and increasing the risk of infection. Monitoring for signs of anemia, leukopenia, and thrombocytopenia is crucial to detect bone marrow suppression early and prevent complications. Choices B, C, and D are incorrect because while methotrexate can increase the risk of infection, liver toxicity, and kidney issues, the primary concern and most significant adverse effect to monitor for is bone marrow suppression due to its impact on blood cell production.

4. A client with diabetes mellitus type 1 is prescribed insulin glargine. When should the nurse instruct the client to administer this medication?

Correct answer: C

Rationale: Corrected Rationale: Insulin glargine is a long-acting insulin that provides a consistent level of insulin over 24 hours. Administering it at bedtime helps mimic the body's natural insulin secretion pattern and provides optimal blood glucose control during the night and throughout the day. Choice A (Before meals) is incorrect because insulin glargine is not a rapid-acting insulin meant to cover meals. Choice B (After meals) is incorrect as the timing doesn't align with the insulin's mechanism. Choice D (In the morning) is incorrect as administering insulin glargine in the morning may not provide adequate coverage throughout the night and the following day.

5. The practical nurse administered carbidopa-levodopa to a client diagnosed with Parkinson's disease. Which outcome by the client would indicate a therapeutic response?

Correct answer: B

Rationale: The correct answer is B: Lessening of tremors. Carbidopa-levodopa increases the amount of levodopa to the CNS, providing more dopamine to the brain. Increased dopamine levels help alleviate Parkinson's symptoms such as tremors, involuntary movements, and gait abnormalities. Choices A, C, and D are incorrect as carbidopa-levodopa is not expected to have a direct effect on blood pressure, salivation, or attention span in the context of treating Parkinson's disease.
