A nurse is preparing to administer a client's antihypertensive medication. When using clinical judgment, which of the following findings indicates the nurse should further assess the client before administering medication?

Choice A rationale While monitoring nutritional intake is important for overall health, eating only 60 percent of breakfast is not a direct contraindication for administering antihypertensive medication. Poor appetite might be relevant if the patient were taking insulin or had significant electrolyte imbalances, but it does not typically alter the immediate safety profile of a blood pressure drug. Unless the patient is experiencing nausea or vomiting that prevents oral intake, this finding does not require urgent assessment before medication. Choice B rationale Reporting trouble sleeping is a common subjective finding in hospitalized patients and does not usually necessitate withholding or delaying antihypertensive therapy. While chronic sleep deprivation can influence long-term blood pressure trends, it is not an acute assessment finding that indicates a high risk for an adverse drug event. The nurse should document the sleep issue and address it later, but it does not take priority over evaluating signs of hemodynamic instability before dosing. Choice C rationale Dizziness when ambulating is a classic symptom of orthostatic hypotension or significantly low blood pressure. Antihypertensive medications further lower blood pressure, which could exacerbate this dizziness and increase the client's risk for falls and injury. The nurse must assess the client's current blood pressure and heart rate, perhaps performing orthostatic vitals, to determine if it is safe to proceed with the medication. This finding indicates a potential safety risk that requires immediate clinical judgment. Choice D rationale A urine output of 400 mL over 8 hours averages to 50 mL per hour, which is well above the minimum safe threshold of 30 mL per hour. This indicates that the client has adequate renal perfusion and kidney function at this time. Since the output is within normal limits, it does not provide a reason to delay antihypertensive administration. In fact, maintaining controlled blood pressure is essential for protecting long-term renal health and preventing hypertensive kidney damage.
