A nurse is carrying for four clients. Which one would the nurse see first?

A. Client who needs a beta blocker and has a blood pressure of 98/58 mm Hg: Administering a beta blocker to a client with hypotension can further lower blood pressure, increasing the risk of dizziness, syncope, or organ hypoperfusion. While this client requires careful monitoring and medication timing adjustments, it is not the most immediate priority. B. Hypertensive client with blood pressure of 178/92 mm Hg: Severe hypertension increases the risk of stroke, myocardial infarction, or organ damage, but if the client is asymptomatic and stable, immediate intervention may not be urgent. Blood pressure management can often wait for assessment of more acutely at-risk clients. C. Client who needs pain medication prior to dressing change of a surgical wound: Pain management is important for client comfort and procedure tolerance, but it is not immediately life-threatening. Administering analgesics can be scheduled shortly before the dressing change without immediate risk to the client. D. Client who had a first dose of captopril and needs to use the bathroom: This client should be seen first because captopril can cause first-dose hypotension, dizziness, or syncope, especially when standing. Immediate assistance to the bathroom is necessary to prevent falls or injury, making this the priority nursing intervention according to the principles of safety fall prevention guidelines.
