Monitoring a patient’s blood pressure during ambulation primarily helps detect which of the following?

• A. Dizziness or lightheadedness.
• B. Infection.
• C. Dehydration.
• D. Cognitive impairment.

Answer: (A)

Monitoring blood pressure during ambulation assesses how well the body maintains blood flow to the brain as you move and change posture. The primary concern is orthostatic or exertional drops in blood pressure that can cause dizziness or lightheadedness. If the patient becomes dizzy, lightheaded, or faint, it signals they may not safely tolerate walking at that moment, and you should stop the activity and reassess to prevent a fall.

Infection isn’t identified by this check during ambulation; dehydration can contribute to blood pressure changes, but the main purpose here is to detect symptoms of inadequate cerebral perfusion. Cognitive impairment isn’t diagnosed through blood pressure monitoring alone.
