The Nurse Reminds the Client Who Has Received a Heart

The nurse reminds the client who has received a heart transplant to change positions slowly.Why is this instruction a priority?

A) Rapid position changes can create shear and friction forces, which can tear out internal vascular sutures.
B) The new vascular connections are more sensitive to position changes, leading to increased intravascular pressure.
C) The new heart is denervated and is unable to respond to decreases in blood pressure caused by position changes.
D) The recovering heart diverts blood flow away from the brain when the client stands, increasing the risk for stroke.
