Your patient is reporting a complete resolution of his symptoms 3 weeks after starting the H2 antagonist medication, cimetidine. His prescription is for 4 weeks of treatment, Which statement best reflects what the nurse's instructions should be?

A. "Continuing captopril during pregnancy will not pose any risks to the developing fetus.":Captopril is an ACE inhibitor and is contraindicated in pregnancy due to its high risk of causing fetal malformations, renal failure, or death. Continuing the drug during pregnancy is unsafe and can lead to serious fetal harm.

B. "Switching to another ACE inhibitor is advisable to reduce the risk of teratogenic effects during pregnancy.": All ACE inhibitors carry similar teratogenic risks. Switching to another ACE inhibitor does not eliminate fetal risk. An alternative antihypertensive from a safer class is required.

C. "It is safe to take captopril during the first trimester as the teratogenic effects only occur later in pregnancy.":Teratogenic effects of ACE inhibitors can occur in any trimester, especially affecting fetal renal development in the second and third trimesters. First-trimester exposure can also cause congenital malformations. Use during any stage is unsafe.

D. "Captopril should be discontinued and replaced with an alternative to avoid teratogenic effects on the fetus":Discontinuing captopril before pregnancy and using a safer antihypertensive (e.g., labetalol or methyldopa) reduces the risk of fetal malformations and adverse pregnancy outcomes. Patient education on medication adjustment prior to conception is essential for safety.

A. "Split your dose between meals 3 and 4 to make sure some medication is being taken when you eat": Repaglinide is a rapid-acting meglitinide that must be taken immediately before each meal. Splitting doses between meals is unsafe and can lead to hypoglycemia or inadequate glycemic control.

B. "With the extra meal, you should begin taking an extra dose of medication": Repaglinide’s action is meal-dependent, meaning each dose should correspond to a carbohydrate-containing meal. Adding a dose with the additional meal maintains proper postprandial glucose control and prevents hyperglycemia, ensuring safe and effective therapy.

C. "As long as you feel fine, the extra meal won't affect your medication": Blood glucose may rise with the extra meal if no additional repaglinide is taken. Relying on subjective feelings is unsafe because hyperglycemia may be asymptomatic initially.

D. "Go back to eating 3 times a day for better sugar control": Restricting meals unnecessarily may reduce the patient’s dietary flexibility and quality of life. The safer approach is adjusting medication to match carbohydrate intake rather than restricting meals.
