CNA Catheter Care and Urinary Management 2 — Questions and Answers
Question 1: When performing catheter insertion in a female patient, in which direction should the perineal area be cleaned?
- Front to back (meatus toward anus) (Correct answer)
- Back to front (anus toward meatus)
- In circular motions starting from the outside
- Side to side across the meatus
Correct answer: Front to back (meatus toward anus)
Cleaning front to back prevents contamination of the urethral meatus with rectal bacteria.
Question 2: How far should a urinary catheter typically be inserted in an adult male patient before inflating the balloon?
- 2–3 inches
- 4–6 inches
- 7–9 inches (Correct answer)
- 10–12 inches
Correct answer: 7–9 inches
In adult males, the catheter should be inserted 7–9 inches to ensure the balloon is fully in the bladder and past the prostate.
Question 3: What type of technique must be maintained throughout urinary catheterization?
- Clean technique
- Sterile technique (Correct answer)
- Surgical aseptic technique
- Medical aseptic technique
Correct answer: Sterile technique
Sterile technique is required during catheterization to prevent introducing bacteria into the bladder.
Question 4: Which fluid is used to inflate the balloon of an indwelling Foley catheter?
- Normal saline
- Sterile water (Correct answer)
- Air
- Distilled tap water
Correct answer: Sterile water
Sterile water is the standard fluid used to inflate the Foley balloon, as saline can crystallize and prevent deflation.
Question 5: The CNA encounters resistance while inserting a catheter into a male patient. What is the correct action?
- Apply firm pressure to push through the obstruction
- Withdraw slightly, rotate, and retry gently
- Stop and notify the nurse immediately (Correct answer)
- Use a larger catheter to dilate the urethra
Correct answer: Stop and notify the nurse immediately
Resistance during catheter insertion may indicate obstruction such as an enlarged prostate, and the nurse must be notified immediately.
Question 6: To which part of the body should the catheter tubing be secured to prevent urethral trauma in a male patient?
- Inner thigh
- Lower abdomen (Correct answer)
- Hip
- Upper thigh
Correct answer: Lower abdomen
Securing the catheter to the lower abdomen in males reduces pressure on the penoscrotal angle and prevents urethral trauma.
Question 7: A patient has a severely distended bladder and a catheter is inserted. How much urine should be drained at one time to avoid complications?
- Up to 200 mL, then clamp for 30 minutes
- Up to 500 mL, then clamp for 15–30 minutes (Correct answer)
- All urine should be drained at once without stopping
- Up to 1,000 mL, then clamp for 1 hour
Correct answer: Up to 500 mL, then clamp for 15–30 minutes
Draining more than 500 mL at once from a severely distended bladder can cause hypotension and bladder spasms.
