Stool specimens are collected to test for a variety of disorders from colon cancer to parasites. While it is not the most pleasant job, it is important that the collection is done correctly for accurate results.

How to Collect a Stool Specimen

  1. Gather the following supplies:
    • Gloves
    • Specimen pan (aka, hat) for the toilet or a bedpan
    • Specimen cup and lid
    • Appropriate label
    • Tongue blades
    • Biohazard bag
    • Toilet tissue or perineal care supplies
  2. Give the patient privacy by closing the door or curtain.
  3. Perform hand hygiene and don gloves.
  4. Ask the patient to urinate in the toilet or in the bedpan.
    • If in the bedpan, empty the urine into the toilet, and then clean and dry the bedpan.
    • If in the toilet, flush the urine, and then place the specimen pan toward the back of the toilet.
  5. Place the patient on the bedpan or help him onto the toilet. Give the patient time and privacy (while maintaining safety) to have a bowel movement. Return when the patient calls or signals that he is done.
    • If the patient is able to clean himself after the bowel movement, provide a trash receptacle for him to dispose of his toilet tissue. The tissue should not be placed in the specimen pan or bedpan with the stool.
  6. Assist the patient with perineal care and hand hygiene if necessary. Remember to discard the supplies in a container separate from the stool.
  7. Help the patient back to the bed.
  8. Note the amount and characteristics (color, consistency, smell) of the stool.
  9. If the stool is formed (has shape):
    • Use a tongue blade to scoop 2 tablespoons of stool into the specimen container, including any blood, mucus, or other discharge.
    • Take the sample from the center or from two different places per the order.
    • Wrap the tongue blade in toilet tissue and dispose appropriately.
  10. If the stool is unformed (liquid):
    • Carefully pour approximately 2 tablespoons of the stool into the specimen container.
  11. Place the lid on the specimen container and make sure the lid is tight.
  12. Change gloves.
  13. Place the patient’s name label on the container with the date, time, and initials of the collector per policy. This label may go on the outside of the biohazard bag, depending on institutional policy.
  14. Place the specimen container into a biohazard bag.
  15. Empty the remaining stool into the toilet and flush. Clean or dispose of the bedpan or specimen pan.
  16. Remove gloves and perform hand hygiene.
  17. Document the bowel movement per unit or institutional policy.
  18. Transport the specimen to the lab per institutional policy.

Offering the Bedpan

When a resident is bed-bound, they must use a bedpan to urinate and defecate. This can be embarrassing for the resident, so it should be done with sensitivity to the resident’s privacy and dignity. There are two types of bedpans. A regular bedpan is the deeper and more rounded of the two. A fracture pan has a relatively flat upper end with a trough at the lower end. Fracture pans are used for residents who have difficulty, or restrictions against, moving their hips and/or backs.

Logrolling the Resident

Logrolling is a technique used to roll a resident onto their side without the resident helping, and while keeping the resident’s spine in a straight line. This is especially important for residents who have had spinal surgery or injury.

Nail Care (Fingers and Toes) for CNAs

Nail care of both the feet and the hands should be performed as part of the patient’s daily hygiene routine. The status of the patient’s nails can reflect their overall health. Nail issues can also lead to infection that can spread systemically (ex, ingrown nails or fungus). You should never clip a patient’s nails with nail clippers, and always review your institution’s policy about what nail care is allowed.

Using a Gait / Transfer Belt to Assist the Resident to Ambulate

Walking (aka, ambulating) helps residents maintain mobility and independence, and prevents complications. However, ambulation must be done safely so that the resident does not have a fall or injury. A gait or transfer belt, when properly used, can increase resident safety. Gait belts can vary between facilities, so make sure you know how to use the one in your facility.

Partial Bed Bath

Bathing is an important part of a patient’s health routine. A partial bed bath focuses on bathing sensitive areas that cause discomfort if not cleansed frequently, such as the face, hands, axillae, back, and perineum. Though patients receiving a bed bath are typically confined to the bed, some are able to wash themselves and should be encouraged to do so to promote independence.
