What is the primary reason for raising the head of the bed and letting the patient's legs dangle before helping them stand?

  1. To improve blood circulation

  2. To prevent the patient from falling

  3. To prevent orthostatic hypotension

  4. To make the patient feel more comfortable

The correct answer is: To improve blood circulation

Raising the head of the bed and letting the patient's legs dangle before helping them stand is done primarily to improve blood circulation. This position helps the blood flow from the legs back towards the heart, which can reduce the risk of dizziness or fainting when the patient stands up. Options B, C, and D are not the primary reasons for this positioning.
