A nurse on a medical-surgical unit is caring for a group of clients. Which of the following clients should the nurse see first?

Hypertensive crisis is a severe increase in blood pressure that can lead to organ damage or other complications. Prompt assessment and intervention are necessary to prevent further escalation of blood pressure and potential complications. While all the clients mentioned require attention, the client with elevated blood pressure and a headache poses a higher immediate risk. The nurse should assess the client's blood pressure, evaluate for signs of target organ damage, and initiate appropriate interventions, which may include administering antihypertensive medications as prescribed and monitoring closely for any changes in the client's condition. The client who is postoperative and reports intermittent nausea can be assessed and managed after addressing the client with the elevated blood pressure and headache. The client scheduled for surgery in 2 hours can be addressed according to the scheduled timeline.
