Final answer:
A patient can safely go without urinating for 6-8 hours after Foley catheter removal. Urine output increases about 30 minutes after fluid ingestion, with diuresis peaking around one hour and normalizing after three hours.
Step-by-step explanation:
After removing a patient's Foley catheter, it is generally considered safe for them to go without urinating for 6-8 hours (Option B). However, this can vary depending on the individual's health status and the reason for catheterization. If it has been more than 8 hours without the patient being able to urinate, medical advice should be sought. It's essential to monitor the patient for signs of urinary retention, discomfort, or distention.
Regarding urine production following fluid intake, the kidneys will start to increase urine output approximately 30 minutes after drinking a large glass of water. This process, known as diuresis, peaks after about one hour and returns to normal production after about three hours.
