题目：
During the first 24 hours after a client is diagnosed with addisonian crisis, which of the following should the nurse perform frequently
A．Weigh the client.
B．Test urine for ketones.
C．Assess vital signs.
D．Administer oral hydrocortisone.
答案：
参考答案：C
解析：Because the client in addisonian crisis is unstable, vital signs and fluid and electrolyte balance should be assessed every 30 minutes until he's stable. Daily weights are sufficient when assessing the client's condition. The client shouldn't have ketones in his urine, so there is no need to assess the urine for their presence. Oral hydrocortisone isn't administered during the first 24 hours in severe adrenal insufficiency.
