Final answer:
The nurse should administer an antihypertensive medication first to help lower the patient's high blood pressure.
Step-by-step explanation:
The nurse should administer an antihypertensive medication first to help lower the patient's high blood pressure of 200/110 mm Hg.
One option for an antihypertensive medication is a calcium channel blocker such as amlodipine or diltiazem. These medications relax and widen the blood vessels, decreasing blood pressure.
Managing the patient's high blood pressure is important to prevent complications and organ damage associated with chronic kidney disease.
