Client #1: 45-year-old male admitted to the hospital for migraine and dehydration Client reports a history of hypertension and has an allergy to codeine Client #2: 68-year-old client admitted to the hospital with influenza.

Client has a history of chronic hypertension Client #4: 54 year old client admitted to the hospital with acute myocardial infarction (MI). Client has allergy to lisinopril. The nurse is caring for a group of clients with orders for calcium channel blocker. For which client should the nurse question the order?

A. Client #1: A 45-year-old male with migraine, dehydration, and a history of hypertension could safely receive a calcium channel blocker if indicated for blood pressure management. No contraindications are present in his profile that would make the order unsafe. B. Client #2: A 68-year-old with influenza and chronic stable angina may benefit from a calcium channel blocker to manage angina symptoms. There are no absolute contraindications based on his current condition or history. C. Client #3: A 39-year-old post-spinal surgery with chronic hypertension could be prescribed a calcium channel blocker for blood pressure control. His surgical status does not contraindicate the use of this medication unless there are specific hemodynamic concerns. D. Client #4: A 54-year-old with acute MI and a lisinopril allergy should raise concern because calcium channel blockers, particularly non-dihydropyridines (like verapamil or diltiazem), may interact with ACE inhibitors and affect cardiac function. Post-MI clients require careful selection of antihypertensive therapy.
