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].

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.

Feeding the Patient

Not all patients will need help feeding themselves. Some patients will only need assistance opening cartons or cutting their food. To promote independence, always let the patient do as much as he or she can before assisting. It is vitally important that the nurse’s aide verifies that the patient receives the correct meal tray. Patients may have special diets that play a critical role in their health (i.e., pureed diet, gluten-free diet, food allergies, etc.). Feeding the wrong food to the wrong patient could result in serious complications.

Orthopneic Position

Patients with respiratory illnesses such as chronic obstructive pulmonary disease (COPD) find ways to help themselves breathe more easily. This can include sleeping with extra pillows to keep them propped up or leaning forward to ease the work of breathing. The orthopneic position is one forward-leaning position used to help patients breathe comfortably when they are having difficulty.

Passive Range of Motion Exercises

Range of motion exercises are used to help prevent or decrease contractures, improve flexibility of joints, and improve strength [1]. Bedridden patients as well as those with reduced mobility may greatly benefit from passive range of motion exercises. However, do not perform these exercises without an order to do so, as it may be contraindicated in certain situations.

Tympanic Membrane Temperature with Electronic Thermometer

A tympanic membrane thermometer uses an infrared sensor to measure the temperature of the tympanic membrane (ear drum). This type of thermometer is considered an accurate and reliable predictor of a patient’s core temperature because the tympanic membrane’s blood supply is sourced from the carotid artery, which is the same artery that carries blood to the hypothalamus in the brain.

Measuring the Respirations

Respiration is a vital sign that is measured frequently in the healthcare setting. Taking this measurement requires no equipment and relatively little time. However, it is a measurement that must be taken accurately, as a change in respiration may indicate the worsening of a patient’s condition.
