2. Right Answer: A
Explanation: (A) Because the extremity may continue to swell and the cast could constrict circulation, the nurse should elevate the limb and observe for capillary refill, warmth, mobility of toes and circulation. (B) Although muscle tone may diminish over time in the affected limb, this is not the immediate concern. (C) The limb has been immobilized already by the cast, and therefore immobilization is not a concern.

(D) Because of the increased risk of atherosclerosis, the fat percentage of the total caloric intake is reduced.
5. Right Answer: D
Explanation: (A) The nurse should discourage the child from coughing, clearing the throat, or putting objects in his mouth. These may induce bleeding. (B) Cool, clear liquids may be given when child is fully alert. Warm liquids may dislodge a blood clot. The nurse should avoid red- or brown-colored liquids to distinguish fresh or old blood from ingested liquid should the child vomit. (C) Gargles and vigorous toothbrushing could initiate bleeding. (D) Postoperative hemorrhage, though unusual, may occur.
