A client with a spinal cord injury and subsequent urine retention receives intermittent catheterization every 4 hours. The average catheterized urine volume has been 550mL. What should the nurse do（）
A. Increase the frequency of the catheterizations.
B. Insert an indwelling urinary catheter.
C. Place the client on fluid restrictions.
D. Use a condom catheter instead of an invasive one.
参考答案：A
解析：
As a rule of practice, if intermittent catheterization for urine retention typically yields 500mL or more, the frequency of catheterization should be increased. Indwelling catheterization is less preferred because of the risk of urinary tract infection and the loss of bladder tone. Fluid restrictions aren’t indicated in this case; the problem isn’t overhydration, rather it’s urine retention. A condom catheter doesn’t help empty the bladder of a client with urine retention.
