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. Oral (also known as sublingual) temperature measurement using an electronic monitor is a convenient and accurate method of assessment. It is quick, typically 20 to 30 seconds, and does not require the patient to change position. Oral temperatures are appropriate for most patients; however, patients who cannot breathe through their nose or cannot hold their mouth closed for the duration of the assessment for any reason should have their temperature taken via another route (axillary, tympanic, rectal, etc.).

Obtaining Oral Temperature with an Electronic Monitor

  1. Gather your supplies. These include:
    • Gloves
    • Thermometer
    • Thermometer probe covers
  2. Perform hand hygiene and don gloves (per institutional policy).
  3. Ask the patient if they have had anything to drink or eat in the past 15 minutes or whether they have smoked in the last 2 minutes (food, drink, and smoking can alter the temperature of the oral cavity).
  4. Turn the thermometer on and slide a disposable probe cover over the probe stem until the cover äóìclicksäó into place.
    • Check that you are using the correct probe. Typically, blue indicates that the probe is for oral and/or axillary temperatures while red indicates that the probe is used for rectal temperatures.
  5. Ask the patient to open his mouth and gently place the tip of the probe under the tongue in the posterior portion of the mouth. If needed, press the äóìStartäó button on the thermometer.
  6. Ask the patient to close his mouth around the probe and keep the tip of the probe under his tongue.
  7. The probe should stay in place until the monitor audibly signals (beeps) that the measurement has completed and the final measurement is shown on the display.
  8. Gently remove the probe from the patient’s mouth, then press the ejection button on the probe to remove the probe cover. Discard the probe cover and place probe back in storage position.
  9. Remove gloves and perform hand hygiene.
  10. Document the temperature in the patient’s record and inform the nurse of any significant change from previous temperature per institutional or unit protocol.
  11. Disinfect the thermometer and return it to the storage or charging location per institutional or unit protocol.

Rectal Temperature with Electronic Thermometer

A rectal temperature provides the most accurate core body temperature reading compared to other non-invasive methods. 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.

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.

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.

Applying Elastic Support Hose

Elastic stockings are worn to prevent deep vein thrombosis (DVT) and reduce the pooling of blood in vessels. Many hospitals and care facilities use elastic stockings in patients with reduced mobility, such as surgical patients and/or the elderly. There are a few risks in wearing elastic stockings; however, these risks can be prevented with proper application and care.

Dressing and Undressing a Patient

Patients who have suffered a stroke or have weakness or injury to one side of their body may struggle with dressing and undressing. In order to help these patients regain their strength and independence, it is important that the nurse’s aide only assist them as needed. The nurse’s aide may need to teach patients how to dress and undress safely with their limitations.

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.
