The client reports having trouble sleeping the previous night.
The client reports dizziness when ambulating to the bathroom.

The client ate 60% of their breakfast.
The Correct Answer is B
A. Trouble sleeping the previous night may not be directly related to the decision to withhold antihypertensive medication.
B. Dizziness when ambulating could indicate hypotension, which can be exacerbated by antihypertensive medication. The nurse should collect further data to ensure the patient's blood pressure is safe for medication administration.
C. Urine output is important to monitor but does not directly indicate a need to withhold antihypertensive medication unless associated with other symptoms.
D. Eating 60% of breakfast does not indicate a need to collect further data before administering antihypertensive medication.
