A nurse is caring for a client who has chronic kidney failure. An assistive personnel reports that the client has a blood pressure of 190/110mm Hg. Which of the following actions should the nurse take first?

A. Report the blood pressure reading to the charge nurse: While notifying the charge nurse is important, the nurse should first validate the high reading by rechecking the blood pressure. Acting on a single, unverified reading could lead to unnecessary interventions or missed opportunities for accurate assessment. B. Administer an antihypertensive medication: Administering antihypertensive medication based solely on a report without rechecking the blood pressure could be unsafe. Verification ensures that treatment is based on accurate clinical data and prevents unnecessary medication administration. C. Remeasure the client's blood pressure: The first action should always be to recheck an unusually high or abnormal vital sign reading to confirm its accuracy. Errors can occur during measurement, and accurate confirmation is critical before proceeding with further interventions in a client with chronic kidney failure. D. Instruct the client to remain in bed: While keeping the client in bed can help prevent complications if severe hypertension is confirmed, it is not the priority action. Verifying the blood pressure reading must occur first to determine the appropriate course of action.
