After Teaching a Client Who Is Recovering from a Heart

After teaching a client who is recovering from a heart transplant to change positions slowly,the client asks,"Why is this important?" How should the nurse respond?

A) "Rapid position changes can create shear and friction forces, which can tear out your internal vascular sutures."
B) "Your new vascular connections are more sensitive to position changes, leading to increased intravascular pressure and dizziness."
C) "Your new heart is not connected to the nervous system and is unable to respond to decreases in blood pressure caused by position changes."
D) "While your heart is recovering, blood flow is diverted away from the brain, increasing the risk for stroke when you stand up."
