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.

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.

Perineal Care of the Female Resident

Perineal care should be performed during a bath, after using the bedpan, and/or after incontinence. Proper technique is important for maintaining hygiene, preventing infection, and avoiding skin breakdown. Because of the close proximity between a woman’s urethra, vagina, and anus, it is essential to only wipe in a front to back motion. Wiping in the opposite direction is associated with a greater risk for developing a urinary tract infection.

Perineal Care of the Male Resident

Perineal care should be performed during a bath, after using the bedpan, and/or after incontinence. Special care should be used when performing perineal care on an uncircumcised male. Failure to retract and wash the area under the foreskin can result in infection. Failure to return the foreskin to its normal position can result in paraphimosis.

Prone Position

Prone position is not used as commonly as other patient positions. This position allows for full extension of the hips and the knees and gives many bony prominences a break from continuous pressure. However, placing patients in prone position does not come without the risks of pressure ulcers.

Performing Ostomy Care

Residents who have had a portion of their intestines removed due to illness or trauma may have a temporary or permanent ostomy, which is an opening in the abdomen that is created for the elimination of urine or feces. The portion of the intestine that is connected to the abdominal wall and is visible is called the stoma. A pouch is placed over the stoma to collect feces.

Measuring the Radial Pulse

The radial artery, located in the wrist, is easy to feel and an efficient location to measure heart rate. Changes to the rhythm or strength of the radial pulse can indicate heart disease, damage to the arm, or body fluid status. It is important to remember to check the radial pulse on both sides as differences between left and right can indicate injury or disease processes.
