Procedure

Equipment needed: rectal thermometer, disposable probe cover, lubricant, tissue, and gloves

  1. Perform hand hygiene and put on gloves.
  2. Explain the procedure to the patient and ask for their assistance in following directions.
  3. Raise the side rail on the patient’s left side for safety. If the bed can be raised, adjust it to a comfortable working height.
  4. Assist the patient into Sims’ position (left side lying).
  5. Adjust the linens to expose only the buttocks.
  6. Apply a disposable cover to the temperature probe. Be sure the probe cover is secure and locked into place.
  7. Apply an adequate amount of lubricant to the probe cover. Ensure the tip and 1-2 inches of the probe is lubricated.
  8. Using one hand, separate the buttocks to expose the anus.
  9. With the other hand, insert the lubricated probe 1-1.5 inches into the rectum in the direction of the umbilicus. If there is any resistance, stop the procedure immediately, withdraw the probe carefully, and notify the medical professional. Do not force the probe into the rectum.
  10. Hold the probe in place until the thermometer signals completion (depending on the device, it may flash or beep). Read the temperature on the electronic display screen.
  11. Gently remove the probe and eject the disposable probe cover into the waste bin.
  12. Use a tissue to wipe away any excess lubricant or feces found around the patient’s anus. Dispose of the tissue in the proper waste receptacle.
  13. Assist the patient back into a comfortable position and, if raised, return the bed to the lowest setting.
  14. Return the thermometer to its base unit.
  15. Remove gloves and perform hand hygiene.
  16. Record temperature, method used (rectal), date, and time in the patient’s chart.
  17. Alert the medical professional of any changes in the patient’s condition.

Important Information

A rectal temperature provides the most accurate core body temperature reading compared to other non-invasive methods [1]. This makes a rectal temperature desirable; however, this procedure comes with more patient discomfort and more safety risks (bowel perforation, mucosal damage, and/or vagus nerve stimulation) than the other temperature measurement methods [2]. In order to avoid these risks, the nurse’s assistant must communicate with the patient throughout the procedure, encouraging him or her to relax, take deep breaths, and remain still.

Prior to performing a rectal temperature, the nurse’s assistant should verify with the nurse that the patient does not have any of the following contraindications: diarrhea, hemorrhoids, rectal bleeding, rectal disease, recent rectal surgery, bleeding tendencies, neutropenia, or certain heart conditions [3].

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.

Supine Position

Supine position is a natural and comfortable position for most people. For this reason, it is a highly utilized position for nursing procedures. Unfortunately, this position puts pressure on many bony prominences that can lead to discomfort and/or pressure ulcers if the pressure is not relieved every so often (typically every two hours or less).

Applying a Condom Catheter

Condom catheters are used for men who are incontinent. These catheters are external and are meant to be used short-term and changed daily.

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.

Assisting the Resident to Sit on the Side of the Bed

Having the resident sit on the side of the bed is otherwise referred to as dangling. When a resident quickly changes position, especially from lying to sitting or standing, there can be a rapid drop in the resident’s blood pressure. This drop in blood pressure may cause dizziness or lightheadedness.

Oral Temperature Measurement with an Electronic Monitor

Body temperature is one of the vital signs frequently measured in healthcare settings. Changes in a body temperature can indicate improvement or worsening of a patient’s condition, so accurate measurement is important.
