Why is it important to position a patient with legs dangling before standing?

• A. To prevent orthostatic hypotension and dizziness.
• B. To improve leg muscle strength.
• C. To calm anxiety.
• D. To reduce risk of infection.

Answer: (A)

This item is about safely transitioning to an upright position to prevent a drop in blood pressure, known as orthostatic hypotension. When you stand quickly, gravity pulls blood into the legs, reducing the amount returning to the heart. That lowers cardiac output and blood pressure, which can cause dizziness or fainting. Letting the legs hang before standing gives blood time to shift back to the central circulation and lets the body’s automatic adjustments stabilize blood pressure and ensure the brain still gets enough blood. This makes standing safer and reduces fall risk. The other options don’t address this immediate cardiovascular change: strengthening muscles happens with longer-term exercise, calming anxiety is not the primary physiological issue here, and infection risk isn’t influenced by leg position.
