Final answer:
If a nurse suddenly sees bright red drainage from a urinary catheter, this may indicate urine retention. It is important to notify a healthcare provider to identify the underlying cause and prevent complications.
Step-by-step explanation:
If a nurse suddenly sees bright red drainage from the urinary catheter, it may indicate urine retention. Urine retention occurs when the bladder is unable to fully empty, leading to a buildup of urine in the bladder. This can be caused by various factors, such as an obstruction in the urinary tract or weak bladder muscles.
For example, if there is a blockage in the urethra or a problem with the sphincter muscles that control urination, urine may back up into the bladder and cause it to overflow. The bright red color in the drainage could be a result of blood mixing with the urine due to bladder irritation or injury.
If a nurse observes this symptom, it is important to notify the healthcare provider immediately. The underlying cause of urine retention needs to be identified and treated to prevent complications such as urinary tract infections or kidney damage.
