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.

Fowler’s Position

Fowler’s position is used when a patient is eating, is having difficulty breathing, or is ordered by a doctor. This position is easily recognized because the patient will be sitting “straight up.” Semi-Fowler’s is sitting “half-way up,” and is used when patients cannot be laid flat, but wish to be in a more relaxed position than Fowler’s.

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.

Making an Occupied Bed

If a patient is bedridden or on bedrest, the bed linens will need to be changed while the patient is in the bed. For safety reasons, the nurse’s aid should avoid making an occupied bed if the patient is able to get out of bed. Bed linens should be changed according to the facility’s policy or anytime they are wet or soiled.

Measuring the Apical Pulse

The apical pulse rate is the most accurate non-invasive measurement of heart rate because it is measured directly over the apex of the heart. Apical pulse is preferred in cases when the radial pulse is difficult to palpate, when the pulse is irregular, greater than 100 beats per minute, or less than 60 beats per minute when measured by other means (electronic, radial, etc.).

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.
