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 C
Explanation
A. Emptying the drainage bag when half full:
This helps prevent backflow and tension on the catheter. It is an appropriate action.
B. Kinking the catheter tubing to obtain a urine specimen:
While not ideal, temporary kinking (with care) may be done to collect a specimen. This is not the worst safety breach.
C. Placing the drainage bag on the side rail of the patient's bed:
The bag must be kept below bladder level to prevent reflux and infection. Side rails can move, leading to unsafe positioning.
D. Securing the catheter tubing to the patient's thigh:
Properly securing the catheter prevents traction and reduces the risk of injury or dislodgement.
Correct Answer is F,E,A,C,B,D
Explanation
1. Clean injection port:
This is done after clamping and before connecting the syringe to prevent introducing infection.
2. Inject prescribed solution:
Done only after the syringe is connected to the port.
3. Twist needleless syringe into port:
This ensures a secure and sterile connection before irrigation.
4. Remove clamp and allow to drain:
This step ensures the irrigant and urine can flow out properly after irrigation.
5. Clamp catheter just below specimen port:
Done early to allow retention of solution during irrigation and prevent backflow.
6. Draw up prescribed amount of sterile solution ordered:
First step—preparing the exact amount of irrigation fluid needed.
