CNA Toileting and Elimination 2 — Questions and Answers
Question 1: How should a CNA position a female patient for bedpan use?
- Flat on her back with legs together
- In a semi-recumbent position with head of bed raised, hips flat on the bedpan (Correct answer)
- On her side with the bedpan placed behind her
- Standing at the bedside with the bedpan on the floor
Correct answer: In a semi-recumbent position with head of bed raised, hips flat on the bedpan
Raising the head of the bed places the patient in a more natural position for elimination, reduces strain, and improves comfort and success.
The fracture bedpan or regular bedpan should be placed with the patient's buttocks centered on it. Raising the head of the bed 30–45 degrees (if not contraindicated) uses gravity to assist elimination and is more comfortable and physiologically natural for the patient. The CNA should provide privacy, a call light, and toilet tissue within reach.
Question 2: A patient has a urinary catheter. What is the correct position for the drainage bag?
- At the same level as the bladder for accurate measurement
- Above the level of the bladder to prevent reflux
- Below the level of the bladder to maintain gravity drainage (Correct answer)
- Attached to the side rail at any height for convenience
Correct answer: Below the level of the bladder to maintain gravity drainage
The catheter drainage bag must always be kept below bladder level to use gravity for drainage and to prevent urine from flowing back into the bladder, which increases infection risk.
Urine drains from the bladder through the catheter tube into the collection bag by gravity. If the bag is raised above bladder level, drainage ceases and urine can reflux into the bladder, introducing bacteria and dramatically increasing the risk of catheter-associated urinary tract infection (CAUTI). The bag should never touch the floor either, to prevent contamination.
Question 3: A CNA notices a patient's urine output for the past 8 hours is only 100 mL. What should the CNA do?
- Encourage the patient to drink more fluids and reassess in 8 hours
- Record it on the intake and output sheet and immediately report it to the nurse (Correct answer)
- Assume the patient simply did not drink enough and continue regular care
- Compare to the prior shift's output and document only if there is a trend
Correct answer: Record it on the intake and output sheet and immediately report it to the nurse
Normal adult urine output is approximately 30 mL/hour or more. 100 mL over 8 hours (12.5 mL/hr) represents oliguria, which may indicate dehydration, renal failure, or hemodynamic compromise — requiring immediate nursing assessment.
Oliguria (urine output < 30 mL/hr) is a significant clinical sign that warrants prompt reporting. Causes range from dehydration (often correctable) to acute kidney injury, urinary obstruction, or systemic hemodynamic compromise. The nurse needs this information promptly to initiate assessment and intervention. Documentation alone without reporting is insufficient.
Question 4: What should a CNA do when a patient reports straining and pain during a bowel movement?
- Administer a stool softener from the medication cart
- Give the patient a suppository for immediate relief
- Document the complaint and report it to the nurse (Correct answer)
- Advise the patient to drink more water and try again later
Correct answer: Document the complaint and report it to the nurse
Pain and straining during defecation are clinical symptoms requiring nursing assessment. The CNA documents and reports — not treats — these findings.
Straining and pain during bowel movements can indicate constipation, hemorrhoids, anal fissure, fecal impaction, or other conditions requiring clinical assessment. Medications (stool softeners, suppositories) require a nurse's or physician's order. The CNA's role is to document the complaint accurately and report it to the charge nurse who will assess and determine appropriate intervention.
Question 5: When assisting an incontinent patient with perineal care, in which direction should the CNA wipe?
- Back to front to reach all areas effectively
- Front to back to prevent fecal contamination of the urethral area (Correct answer)
- In circular motions for thorough cleaning
- Any direction using disposable wipes
Correct answer: Front to back to prevent fecal contamination of the urethral area
Front-to-back wiping prevents bacteria from the anal area from contaminating the urethra, significantly reducing urinary tract infection risk.
The urethra is proximal (anterior) and the anal opening is distal (posterior). Wiping from front to back moves contaminated material away from the urethral opening. Wiping back to front introduces fecal bacteria near the urethral opening, which is the primary mechanism of urinary tract infection in women. This principle applies to both male and female patients.
Question 6: A patient has a colostomy. What is the CNA's primary role in colostomy care?
- Creating and repositioning the stoma with specialized tools
- Emptying and changing the ostomy pouch, cleaning the peristomal skin, and reporting any stoma changes to the nurse (Correct answer)
- Prescribing the appropriate pouch system for the patient's anatomy
- Diagnosing complications such as stomal stenosis
Correct answer: Emptying and changing the ostomy pouch, cleaning the peristomal skin, and reporting any stoma changes to the nurse
CNA colostomy care focuses on pouch management, skin protection, and observation, with all clinical findings reported to the nurse.
CNAs can be trained to empty and change ostomy pouches, clean and dry the peristomal skin, and apply skin barriers as part of their care plan responsibilities. The CNA should report any changes: bleeding from or around the stoma, discoloration (pale, dark, dusky), retraction, prolapse, or skin breakdown. Clinical assessment and product selection remain with the nurse and wound/ostomy specialist.
