单项选择题
A 32-year-old black man is admitted to the hospital in vaso-occlusive sickle cell crisis. He complains of chest pain, shortness of breath, severe myalgia, and arthralgia. Which of the following may be effective in relieving the client's joint pain
A．Applying ice packs to the joints.
B．Performing active resistive range-of-motion exercises.
C．Applying warm compresses to the joints.
D．Applying transcutaneous electrical nerve stimulation (TENS).
答案
参考答案：C
解析：Warm compresses increase blood flow to the affected joint, relieving pain. Ice causes decreased blood flow to the affected joint, increasing pain. The nurse should turn the client frequently to prevent skin breakdown and conserve the client's energy. TENS application is reserved for chronic pain.
