Why should the nurse caution the client who has received a heart transplant to change positions slowly?
A. Rapid position changes can create shear forces and disrupt 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 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.
C
Because the new heart is denervated, the baroreceptor and other mechanisms that compensate for blood pressure drops when positions are changed do not function, allowing orthostatic hypoten-sion to persist in the postoperative period.
