Pharmacology HESI Practice

Correct Answer: A

Rationale: In this scenario, the client has developed a rash after starting oral penicillin, which can indicate an allergic reaction. It is crucial for the nurse to instruct the client to discontinue the penicillin immediately. Continuing the medication can potentially lead to severe allergic reactions. Instructing about topical analgesic cream or questioning about other related symptoms may delay appropriate action in case of a severe allergic reaction. Reinforcing the need to complete all doses is not appropriate when an allergic reaction is suspected, as safety takes precedence over completing the antibiotic course.

Correct Answer: A

Rationale: Clients should not stop taking risperidone abruptly once they feel better without consulting their healthcare provider.

Correct Answer: D

Rationale: Tiotropium is commonly used for COPD management.

Correct Answer: D

Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.

Correct Answer: C

Rationale: The correct answer is C. Donepezil is a medication used for individuals with Alzheimer's disease. Its mechanism of action involves increasing acetylcholine levels by inhibiting its breakdown, which benefits cognitive function. The expected outcome of administering donepezil is a decrease in confusion and an improvement in mood due to the medication's impact on neurotransmitters. Choices A, B, and D are incorrect because donepezil does not primarily target muscle strength, urinary incontinence, or disease reversal; instead, it aims to slow down the progression of cognitive decline in Alzheimer's disease.
