While being catheterized for urinary retention, the patient becomes diaphoretic

1 -- Some patients may experience a vasovagal response and become pale, sweaty and hypotensive if the bladder is rapidly drained. The vasovagal response is not to be an expected response in each patient during catheterization. The nurse should be aware that it is a possible response in some patients and be able to recognize and respond to it. Draining 500 mL increments and clamping the catheter for 5 to 10 minutes between increments may prevent this response. Removing the urinary catheter or replacing fluids will not address the symptoms.
