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].

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.

Applying Restraints

Restraints have very strict guidelines for use due to the number of complications that can result. Use of restraints is associated with increased physical and psychosocial health issues. Restraints are only considered necessary when restraint-free alternatives have failed and the patient or others are at risk of harm without the restraints. It is illegal to use restraints for the staff’s convenience or to punish the patient.

Moving the Resident to the Side of the Bed

Residents are usually kept in the center of the bed for safety reasons. However, moving a resident to the side of the bed is an important step to take before turning a resident onto his or her side. Performing this action allows the resident to end up side lying in the center of the bed and not smashed up against the side rail.

Removing Personal Protective Equipment

It is important to follow the correct procedure while removing personal protective equipment to avoid contaminating your skin or clothing. The most common source of contamination in this process stems from improper removal of gloves. Gloves are often the most soiled piece of equipment. To avoid contaminating your skin or the other equipment worn, gloves should always be removed first. Then remove the goggles, gown, and mask, in that order.

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.

Measuring and Recording Output from a Urinary Drainage Bag

Accurate measurement of urination (aka, the output portion of intake and output) allows medical personnel to assess kidney and bladder function. Changes in output quantity or quality can reflect health status changes including new-onset infection or renal injury.
