单项选择题
A client on prolonged bed rest has developed a pressure ulcer. The wound shows no signs of healing even though the client has received skin care and has been turned every 2 hours. Which factor is most likely responsible for the failure to heal
A．Inadequate vitamin D intake.
B．Inadequate protein intake.
C．Inadequate massaging of the affected area.
D．Low calcium level.
答案
参考答案：B
解析：A client on bed rest suffers from a lack of movement and a negative nitrogen balance. Therefore, inadequate protein intake impairs wound healing. Inadequate vitamin D intake and low calcium levels aren't factors in poor healing for this client. A pressure ulcer should never be massaged.
