单选题 A client who has been using crutches at home for t week reports that he is having trouble using the crutches because his armpits hurt and his fingers tingle. What would be the nurse's most appropriate response

A、 "You need to do more arm exercises. It sounds like your muscles need strengthening. "
B、 "That's normal. As you adjust to the crutches, the discomfort will diminish. "
C、 "Be sure to take your pain medication before ambulating. That will help your discomfort. "
D、 "Let me watch you ambulate. Your crutches or technique may need some adjustment. "

【正确答案】 D

【答案解析】The nurse should reevaluate the client's use of his crutches because pressure on the axillae from the crutches can lead to "crutch paralysis" secondary to pressure on the brachial plexus nerves. This pressure can result from crutches that are used inappropriately or sized incorrectly.
