A nurse is administering the first dose of ramipril to a client who has hypertension. The client reports feeling dizzy and lightheaded. Which of the following should the nurse administer?

A. 15 g of carbohydrates: This is used for hypoglycemia, not for hypotension. B. Naloxone: Naloxone is an opioid antagonist, not relevant for ramipril-related symptoms. C. Diphenhydramine: This is an antihistamine and not indicated for ramipril-related dizziness. D. Fluid bolus: Dizziness and lightheadedness after starting an ACE inhibitor like ramipril may be due to hypotension. A fluid bolus can help restore blood volume and alleviate these symptoms.
