Beta-adrenergic blocking drugs are used in children for disorders similar to those in adults. What adrenergic blocking agent is used during surgery for pheochromocytoma?
Correct Answer: C
Rationale: Phentolamine is used during surgery for pheochromocytoma in children. Prazosin is used to treat hypertension in children.

Question 3 of 5
A patient with type 2 diabetes mellitus asks the nurse how metformin decreases blood sugar. What is the best response by the nurse?
Correct Answer: A
Rationale: Metformin primarily works by decreasing hepatic glucose production and improving insulin sensitivity in peripheral tissues.

Question 4 of 5
A nurse is giving medicinal instructions to a female client receiving leflunomide (Arava). Which of the following is an appropriate instruction with the use of the medication?
Correct Answer: A
Rationale: Leflunomide is teratogenic and can cause severe birth defects. Women of childbearing age must use effective contraception during treatment and for a period after discontinuation. Breastfeeding is contraindicated due to the risk of harm to the infant. Cholestyramine is used to accelerate the elimination of leflunomide in case of toxicity, not to lessen side effects. Improvement in symptoms typically takes weeks, not days.
Question 5 of 5
Which of the following is most effective as a topical agent for a candida infection of the skin?
Correct Answer: D
Rationale: Cutaneous candidiasis needs topical antifungals. Griseofulvin treats dermatophytes orally, not candida topically. Beclometasone, a steroid, worsens fungal growth. Aciclovir targets herpes, not fungi. Amphotericin is IV for systemic use. Nystatin binds ergosterol in candida membranes, most effective topically for skin infections, widely used for its specificity and safety.
