A 30-year-old client with 7 months pregnancy reports severe leg cramps at night. Which nursing action would be most effective in helping her cope with these cramps
A．Suggesting that she walk for 1 hour twice per day.
B．Advising her to take over-the-counter calcium supplements twice per day.
C．Teaching her to dorsiflex her foot during the cramp.
D．Instructing her to increase milk and cheese intake to 8 to 10 servings per day.
参考答案：C
解析：Common during late pregnancy, leg cramps cause shortening of the gastrocnemius muscle in the calf. Dorsiflexing or standing on the affected leg extends that muscle and relieves the cramp. Although moderate exercise promotes circulation, walking 2 hours per day during the third trimester is excessive. Excessive calcium intake may cause hypercalcemia, promoting leg cramps; the physician must evaluate the client's need for calcium supplements. If the client eats a balanced diet, calcium supplements or additional servings of high-calcium foods may be unnecessary.
