What is postural hypotension?

1. High blood pressure

2. Normal blood pressure

3. Low blood pressure while standing up

4. Low blood pressure while sitting down

The correct answer is: Low blood pressure while standing up

Postural hypotension, also known as orthostatic hypotension, refers to a drop in blood pressure that occurs when an individual stands up from a sitting or lying position. This condition can cause dizziness or lightheadedness due to insufficient blood flow to the brain during the sudden change in posture. When a person stands up, gravity pulls blood down into the legs, and if the body fails to adequately compensate for this shift, blood pressure drops. This is why low blood pressure while standing is the characteristic sign of postural hypotension. Understanding this condition is crucial for caregivers and CNAs, as they need to be aware of its symptoms to provide proper support and assistance to those at risk, especially older adults who may experience these changes in blood pressure more frequently.
