How much urine is too much to drain at one time when a new insertion of a foley catheter is done?
300-450 ml
450-600 ml
750-1000 ml
200-500 ml
The Correct Answer is C
A. 300–450 mL:
This amount is acceptable to drain at one time. It is not considered excessive or dangerous.
B. 450–600 mL:
This is within a safe limit and does not pose risk for bladder spasms or hypotension.
C. 750–1000 mL:
Draining more than 750–1000 mL at once can lead to bladder spasms, hypotension, and hematuria due to rapid decompression of a distended bladder. This is too much to drain at once.
D. 200–500 mL:
This range is considered a safe and appropriate amount to drain in one go for most patients.

Correct Answer is B
Explanation
A. 60:
This is the diastolic pressure, not the pulse pressure.
B. 80:
Pulse pressure = Systolic – Diastolic → 140 – 60 = 80. This is the correct calculation.
C. 140:
This is the systolic pressure, not the pulse pressure.
D. 200:
This is not a relevant value in this context and is mathematically incorrect.
Correct Answer is B
Explanation
A. Measure the patient's urinary output:
Measuring output is important but not the priority. First, the nurse must ensure that urine can drain freely.
B. Ensure that the catheter tubing is not kinked:
This is the priority. A kinked catheter can cause bladder distention and discomfort, leading to a sensation of urgency despite the catheter being in place.
C. Provide perineal care to the patient for comfort:
Comfort is important, but it does not address the potential cause of the urinary sensation.
D. Reassure the patient that the sensation is to be expected:
Sensation may be expected in some patients, but it’s essential to rule out mechanical obstruction first.
