A female patient taking an ACE inhibitor learns that she is pregnant. What will the nurse tell this patient?

Choice A reason: ACE inhibitors are teratogenic, risking fetal harm, so monitoring while continuing is unsafe. Stopping the drug is critical, making this incorrect for safe pregnancy management. Choice B reason: ARBs are also contraindicated in pregnancy due to similar teratogenic risks. Switching to an ARB is not safe, so this is incorrect compared to stopping the medication. Choice C reason: ACE inhibitors can cause fetal abnormalities, so the patient must stop the medication and contact her provider immediately for safer alternatives. This is the correct action. Choice D reason: Continuing ACE inhibitors, even adjusted, is dangerous in pregnancy due to teratogenicity. Immediate cessation and provider consultation are required, making this incorrect.
