A nurse is preparing to administer verapamil to a client who is 2 days postmyocardial infarction.
The nurse should monitor the client for which of the following outcomes as a therapeutic response to the medication?
Increased heart rate.
Increased blood pressure.
Decreased pulmonary congestion.
Decreased anginal pain.
The Correct Answer is D
Choice A rationale
Verapamil is a calcium channel blocker that typically reduces heart rate rather than increasing it by inhibiting calcium ion influx in the heart muscle, which decreases the heart's workload.
Choice B rationale
Verapamil generally lowers blood pressure by relaxing the smooth muscles in blood vessels, leading to vasodilation, not an increase in blood pressure.
Choice C rationale
Verapamil helps reduce pulmonary congestion by decreasing the workload on the heart, which can help alleviate symptoms of heart failure, but this is not the primary therapeutic effect in post-myocardial infarction patients.
Choice D rationale
Verapamil decreases anginal pain by relaxing coronary blood vessels, improving blood flow to the heart, and reducing myocardial oxygen demand, which is a primary therapeutic response.

Correct Answer is A
Explanation
Choice A rationale
Leuprolide decreases testosterone production by acting as a GnRH agonist, initially stimulating then downregulating GnRH receptors in the pituitary gland, reducing LH and FSH levels.
Choice B rationale
Leuprolide does not kill cells at all stages of cellular division; it specifically reduces hormone levels to slow hormone-sensitive cancer growth.
Choice C rationale
Leuprolide does not increase estrogen levels; its primary mechanism involves reducing testosterone levels to manage prostate cancer.
Choice D rationale
Leuprolide does not suppress growth hormone production; it specifically targets gonadotropin release to lower testosterone levels. .
Correct Answer is ["A","B","C","D"]
Explanation
Choice A rationale
Educating the client on the consequences of not taking valproic acid is important for informed decision-making. Without the medication, seizure control may be compromised, leading to potential health risks.
Choice B rationale
Taking valproic acid with food can help minimize gastrointestinal side effects such as nausea by reducing gastric irritation and improving drug absorption.
Choice C rationale
Documenting the client's refusal in the medication administration record ensures accurate medical records and provides information for future healthcare decisions and assessments.
Choice D rationale
Enteric-coated formulations of valproic acid can reduce gastrointestinal irritation by allowing the drug to pass through the stomach and dissolve in the intestine.
