单选题 A child with rheumatic fever complains of painful joints. What nonpharmacologic measures should the nurse use to reduce the child's pain?
A. Performing gentle passive range-of-motion (ROM) exercises.
B. Gently massaging the painful joints.
C. Using a bed cradle to keep linens off the joints.
D. Encouraging position changes in bed every 2 hours.

【正确答案】 C

【答案解析】In rheumatic fever, the joints may be so painful that even the weight of the bed linens can cause pain. A bed cradle lifts the weight of the linens off the child, reducing pain. Pain may be increased when the affected joint is moved; therefore, passive ROM exercises aren't recommended. Pain isn't likely to be relieved by massaging the joints. The child should be encouraged to change positions at least every 2 hours, to reduce the risk of skin breakdown, but this is unlikely to relieve joint pain.
