单项选择题
The nurse is caring for a client who recently underwent a total hip replacement. The nurse should（）
A. ease the client onto a low toilet seat.
B. allow the client’s legs to be crossed at the knees when out of bed.
C. use soft chairs when the client is sitting out of bed.
D. limit client hip flexion when sitting.
答案
参考答案：D
解析：
Instruct the client to limit hip flexion to 90 degrees while sitting. Supply an elevated toilet seat so the client can sit without having to flex his hip more than 90 degrees. Instruct the client not to cross his legs, to avoid dislodging or dislocating the prosthesis. Caution the client against sitting in chairs that are too low or too soft; these chairs increase flexion, which is undesirable.
