A nurse aide is taking a resident's blood pressure while the resident is lying down, then again after the resident stands up, to check for orthostatic hypotension. What symptom should the nurse aide watch for that would confirm this condition?
- AAn increase in body temperature after standing
- BDizziness or lightheadedness upon standing, along with a drop in blood pressure
- CA slower pulse rate that returns to normal within seconds
- DA significant increase in blood pressure upon standing
Show answer & explanationAnswer & explanation
Correct answer: B. Dizziness or lightheadedness upon standing, along with a drop in blood pressure
Orthostatic (postural) hypotension occurs when blood pressure drops significantly upon standing, often causing dizziness, lightheadedness, or fainting due to insufficient blood flow to the brain. This is why blood pressure is checked in both lying and standing positions.
Why the other options are wrong
- A. Body temperature is unrelated to orthostatic blood pressure changes.
- C. Pulse changes alone, without symptoms or BP drop, do not confirm this condition.
- D. Orthostatic hypotension involves a drop in blood pressure, not an increase.
Orthostatic Hypotension
A drop in blood pressure that occurs when a person changes from lying or sitting to standing, often causing dizziness or fainting.
- BP checked lying, sitting, then standing for comparison
- Symptoms include dizziness, lightheadedness, fainting
- Increases fall risk, especially in elderly residents
Memory trick: 'Stand up fast, blood pressure drops, dizziness stops you in your tracks.'
