Elimination care helps residents meet a basic need safely and with dignity. The CNA assists with bedpans, urinals, commodes, and toilets, changes incontinent residents promptly to protect their skin, and observes and reports the color, amount, and character of urine and stool. For a resident with a , the CNA keeps the drainage bag below the bladder, keeps the tubing secured and free of kinks, and reports problems rather than performing sterile procedures.

Why this matters

Elimination care tests both dignity and observation. Residents find this care embarrassing, so the CNA's matter-of-fact, private, respectful manner is itself therapeutic. At the same time, urine and stool are windows into health — a change in color, amount, or frequency is often the first clue of infection, dehydration, or . The exam rewards knowing both the dignity rules (privacy, promptness, respect) and the safety concepts (, bag below the bladder, clean down away from the meatus).

The college version

1. Bedpans, urinals, commodes, and toilets

A is used by a resident who cannot get out of bed, and a urinal is a container for urine, often used by male residents in bed. A standard bedpan is the usual size; a fracture pan is smaller and flatter and is used for residents who cannot raise their hips or who have a fracture, so they do not have to be lifted or moved much. A is a portable bedside chair with a built-in pan, for residents who can get out of bed but cannot walk to the bathroom. A toilet transfer means helping a resident move to the toilet, done toward the resident's strong side and with the assistive equipment the care plan orders. With every method, the CNA protects privacy, keeps the resident covered and warm, and cleans and dries the skin afterward.

2. Incontinence care and catheter care

is the loss of bladder or bowel control. Incontinent residents are checked and changed promptly, because urine and stool left on the skin break it down and lead to skin breakdown, irritation, and pressure injuries; perineal care and a dry barrier product protect the skin. A resident with a urinary catheter has a tube draining urine into a drainage bag. The CNA understands three safety concepts: the drainage bag is kept below the level of the bladder so urine flows down by gravity and does not flow back and cause infection; the tubing is secured so it does not pull on the resident and is kept free of kinks so urine drains freely; and the tubing is cleaned downward, away from the meatus (the opening where the catheter enters the body), so germs are not pushed toward the body. The CNA observes and reports — and never pulls on, disconnects, or performs sterile care on the catheter, which is outside scope.

3. Bowel elimination

Bowel elimination is the passing of stool. Constipation is infrequent, hard, difficult-to-pass stool; if stool becomes hard and stuck and cannot be passed, it is called impaction. The CNA observes and reports stool frequency, consistency, color, and any blood, and reports a resident who has not had a bowel movement for several days or who shows signs of impaction (such as liquid stool leaking around a blockage). An is a surgically created opening (stoma) on the abdomen through which stool or urine empties into a pouch. The CNA observes the stoma and the pouch, reports changes in color or drainage, and empties the pouch as directed — but never inserts anything into the stoma.

How it works

  1. The CNA answers the call light promptly, offers the right equipment, and protects privacy.
  2. The CNA observes and records urine and stool — amount, color, and character.
  3. The CNA cleans the resident and changes soiled items promptly to prevent skin breakdown.
  4. For a catheter, the CNA keeps the bag below the bladder, keeps tubing secured and unkinked, and cleans down the tubing away from the meatus, then reports any concern to the nurse.

Common confusions

ConstipationImpactionConstipation is hard, infrequent stool; impaction is stool stuck and unable to be passed
CatheterOstomyA catheter drains urine from the bladder; an ostomy is a surgical opening for stool or urine
IncontinenceNeglectIncontinence is loss of control and needs prompt, dignified care; leaving a resident wet is neglect

Quick review

Topic Recap

Elimination care helps residents manage urine and stool safely and with dignity. The CNA offers the right equipment — standard or fracture pan, urinal, commode, or toilet — protects privacy, and observes and reports output. Incontinent residents are changed promptly to prevent skin breakdown. For catheters, the CNA keeps the bag below the bladder, secures the tubing, and cleans down the tubing away from the meatus, while reporting rather than performing sterile care. Constipation, impaction, and ostomy care all depend on the CNA's observation and reporting.

Knowledge Check

  1. Which bedpan is used for a resident who has a hip fracture and cannot raise their hips?
  2. Why is the catheter drainage bag kept below the level of the bladder?
  3. In which direction is catheter tubing cleaned relative to the meatus?
  4. A resident has not had a bowel movement in four days and is uncomfortable. What should the CNA do?
  5. Why is prompt changing of an incontinent resident important?

Answers and Rationales

  1. A fracture pan. It is smaller and flatter than a standard bedpan, so the resident does not have to be lifted or moved much, which protects an injured hip.
  2. To let urine drain by gravity and prevent it from flowing back into the bladder, which could cause a urinary tract infection.
  3. Downward, away from the meatus. Cleaning away from the body keeps germs from being pushed toward the catheter opening, reducing infection risk.
  4. Report the finding to the nurse. Four days without a bowel movement signals constipation that may need treatment; removing an impaction or giving an enema is outside CNA scope unless specifically delegated and trained.
  5. Because urine and stool left on the skin break it down, causing irritation, skin breakdown, and pressure injuries. Prompt changing keeps the skin clean and dry.

The same idea, in plain words

Explain it like I’m 10

Elimination is how the body gets rid of urine and stool, and helping with it is one of the most personal kinds of care a CNA gives. Think of it like a private bathroom routine the CNA helps make safe and dignified when a resident cannot manage alone — offering the right equipment, giving privacy, and cleaning up promptly. Where it stops being exact: some elimination care is outside CNA scope. The CNA does not insert or remove catheters, does not perform sterile procedures, and does not give enemas or remove impactions unless specifically delegated and trained. The CNA's job is to assist, observe, and report.

Simple Example

A resident recovering from a hip fracture cannot get out of bed. The CNA offers a fracture pan, which is smaller and flatter than a standard bedpan, so she can stay in a safer position without much movement. Afterward, the CNA cleans her, observes the urine and skin, and reports that her urine is darker than usual and she has not had a bowel movement in several days.

Worked example

  1. The CNA checks the care plan for each resident's elimination needs, equipment, and schedule, and answers call lights promptly, because a resident who waits too long may have an accident or fall trying to hurry.
  2. The CNA provides privacy and the correct equipment — a standard or fracture pan, urinal, commode, or help to the toilet — and positions the resident safely.
  3. The CNA observes the urine and stool: amount, color, odor, and anything unusual such as blood or cloudiness, and notes when the last bowel movement occurred.
  4. The CNA cleans the resident, performs perineal care, and changes wet or soiled linen promptly to protect the skin.
  5. The CNA documents output and reports to the nurse: no urine output, dark or bloody urine, pain with urination, blood in the stool, no bowel movement for several days, signs of impaction, a catheter that is not draining or has been pulled, or a stoma that looks dark or changed.

Key takeaways

  • High yield: Use a fracture pan, not a standard bedpan, for a resident with a fracture or who cannot raise their hips.
  • High yield: Change incontinent residents promptly; urine and stool on skin cause breakdown and pressure injuries.
  • High yield: Keep the catheter drainage bag below the bladder so urine does not flow back and cause infection.
  • High yield: Secure the catheter tubing and keep it free of kinks; never pull on it.
  • High yield: Clean catheter tubing downward, away from the meatus, so germs are not pushed toward the body.
  • Report no bowel movement for several days and signs of impaction.
  • An ostomy is observed and its pouch emptied as directed; never insert anything into the stoma.
