单选题 The nurse is preparing to care for a client diagnosed with catatonic schizophrenia. In anticipation of this client's arrival, what should the nurse do?
A. Notify security.
B. Prepare a magnesium sulfate drip.
C. Place a specialty mattress overlay on the bed.
D. Communicate the client's nothing-by-mouth status to the dietary department.

【正确答案】 C

【答案解析】The nurse should first focus on meeting the client's immediate physical needs and preventing complications related to the catatonic state. The need for intervention from security personnel is unlikely. A magnesium sulfate drip isn't indicated. Nutritional status should be addressed after the client is fully assessed and admitted.
