The nurse uses the palms of the hands when handling a wet cast to:
 
  a. Assess dryness of the cast. c. Keep the patient's limb balanced.
  b. Facilitate easy turning. d. Avoid indenting the cast.

Question 2

What effect does immobilization have on the cardiovascular system?
 
  a. Venous stasis
  b. Increased vasopressor mechanism
  c. Normal distribution of blood volume
  d. Increased efficiency of orthostatic neurovascular reflexes

Answer to Question 1

ANS: D
Wet casts should be handled by the palms of the hands, not the fingers, to prevent creating pressure points. Assessing dryness, facilitating easy turning, or keeping the patient's limb balanced are not reasons for using the palms of the hand rather than the fingers when handling a wet cast.

Answer to Question 2

ANS: A
Because of decreased muscle contraction, the physiologic effects of immobilization include venous stasis. This can lead to pulmonary emboli or thrombi. A decreased vasopressor mechanism results in orthostatic hypotension, syncope, hypotension, decreased cerebral blood flow, and tachycardia. An altered distribution of blood volume is found, with decreased cardiac workload and exercise tolerance. Immobilization causes a decreased efficiency of orthostatic neurovascular reflexes, with an inability to adapt readily to the upright position and pooling of blood in the extremities in the upright position.
