A medical assistant is preparing a patient who has a history of syncope during blood draws for venipuncture. In which of the following positions should the assistant place the patient?
Prone
Trendelenburg
Supine
Fowler's
The Correct Answer is B
A. Prone: The prone position (lying face down) is not suitable for venipuncture or for patients at risk of syncope.
B. Trendelenburg: The Trendelenburg position (lying flat with the legs elevated) can help prevent syncope by increasing venous return to the heart and improving blood flow to the brain.
C. Supine: While the supine position (lying flat on the back) is appropriate for venipuncture, the Trendelenburg position is preferred for patients with a history of syncope.
D. Fowler's: The Fowler's position (sitting or semi-sitting) is not suitable for preventing syncope during blood draws.
