A.
Physical exertion

B.
Eat

C.
Stand up

D.
D. Lie down

The correct answer and Explanation is :

The correct answer is C. Stand up.

Orthostatic (or postural) hypotension refers to a sudden drop in blood pressure when a person stands up from a sitting or lying position. It is diagnosed when there is a significant decrease in systolic (top number) blood pressure by at least 20 mmHg or a decrease in diastolic (bottom number) blood pressure by at least 10 mmHg within three minutes of standing. The condition may lead to dizziness, lightheadedness, fainting, or falls, particularly in elderly or frail patients.

When a nurse checks for orthostatic hypotension, the patient is typically asked to:

1. Lie down for several minutes – The nurse will measure the patient’s baseline blood pressure and heart rate while lying flat to get an accurate resting blood pressure.
2. Sit up – The patient’s blood pressure and heart rate are measured again after sitting to observe any early changes in pressure as the body adjusts to the change in position.
3. Stand up – This is the critical step. The nurse will measure blood pressure and heart rate within one to three minutes of the patient standing to check for signs of orthostatic hypotension.

This method allows the nurse to determine how well the cardiovascular system responds to positional changes, which can help identify issues with autonomic regulation or fluid balance. Orthostatic hypotension may be caused by dehydration, blood loss, certain medications (like diuretics or antihypertensives), prolonged bed rest, or neurological disorders such as Parkinson’s disease. It can also occur in elderly individuals due to decreased responsiveness in blood vessels.

Careful monitoring and management are essential in preventing complications such as falls or fainting. If the condition is identified, treatment may include adjusting medications, increasing fluid intake, or advising gradual positional changes to minimize symptoms.
