Correct Answer is C
Explanation
A) The chair should be placed on the client's stronger (right) side to facilitate a safer and more controlled transfer. The client can use their stronger side to assist in the movement.
B) The bed should be at a comfortable height, ideally level with the chair, to allow a smooth transfer. Raising the bed too high can make it difficult for the client to place their feet firmly on the ground, reducing stability.
C) Locking the wheels on the bed ensures stability and prevents movement while assisting the client with the transfer. This is a crucial safety measure to reduce the risk of falls or injuries during the transfer process.
D) The chair should be positioned at a 45° angle to the bed to allow for a more natural pivot and smoother transfer. A 90° angle can make the movement more difficult and awkward for the client.
Correct Answer is B

C) Red bone marrow is primarily involved in hematopoiesis, not calcium storage.
