A nurse is caring for a client who has been taking captopril for one year. Which of the following laboratory values should the nurse review? (Select all that apply.)
Potassium level.
WBC with differential.
BUN level.
Hemoglobin level.
Glucose level.
Correct Answer : A,B,C
Choice A rationale
Potassium level should be reviewed because captopril can cause hyperkalemia due to its effect on aldosterone secretion.
Choice B rationale
WBC with differential should be reviewed because captopril can cause neutropenia or agranulocytosis, especially in patients with renal impairment or collagen vascular disease.
Choice C rationale
BUN level should be reviewed because captopril can affect renal function, leading to increased BUN levels.
Choice D rationale
Hemoglobin level is not typically affected by captopril, so it is not a priority for review.
Choice E rationale
Glucose level is not typically affected by captopril, so it is not a priority for review.

Correct Answer is B
Explanation
Choice A rationale
Methimazole does not typically cause constipation. It is used to treat hyperthyroidism by inhibiting the production of thyroid hormones.
Choice B rationale
A sore throat can be a sign of agranulocytosis, a serious side effect of methimazole that involves a dangerously low white blood cell count. Patients are advised to contact their provider if they experience a sore throat.
Choice C rationale
While monitoring weight is important for patients with hyperthyroidism, it is not a specific instruction related to methimazole use.
Choice D rationale
Methimazole should be taken regularly as prescribed, not on an as-needed basis.
Correct Answer is D
Explanation
Choice A rationale
Asthma is not a contraindication for sumatriptan. Sumatriptan is a selective serotonin receptor agonist used to treat migraines by constricting blood vessels in the brain. It does not have a significant impact on respiratory conditions like asthma.
Choice B rationale
Kidney disease is not a contraindication for sumatriptan. However, caution is advised when using sumatriptan in patients with severe renal impairment due to potential accumulation of the drug and its metabolites.
Choice C rationale
Rheumatoid arthritis is not a contraindication for sumatriptan. Sumatriptan’s mechanism of action does not interfere with the inflammatory processes involved in rheumatoid arthritis.
Choice D rationale
Coronary artery disease (CAD) is a contraindication for sumatriptan. Sumatriptan can cause vasoconstriction of coronary arteries, which can exacerbate CAD and increase the risk of myocardial infarction or other cardiac events.
