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.).

Measuring the Apical Pulse

  1. Gather your supplies:
    • Gloves
    • Stethoscope
    • Clock or watch with seconds displayed, or a second hand
    • Alcohol swabs
  2. Introduce yourself to the patient, perform hand hygiene, and clean the bell of the stethoscope with an alcohol swab.
  3. Ensure patient privacy by closing the curtain or door.
  4. The patient should be sitting or lying supine. Adjust the bed covers and/or the patient’s clothing so that the sternum and left side of the chest are exposed.
  5. Place the bell of the stethoscope at the fifth intercostal space, at the left midclavicular line. This is the location of the apex of the heart.
    • To find the correct location, first locate the sternal notch at the top of the sternum. Directly beside this is the second intercostal space. Count down three more to reach the fifth intercostal space.
    • The midclavicular line is an imaginary line drawn straight down from the middle of the clavicle (in this case, the left clavicle).
    • Place your stethoscope where the imaginary line and the fifth intercostal space intersect. This is generally just below the breast tissue.
    • It is kind to warm the stethoscope in your hands before placing it on the patient to avoid an unexpected chill.
  6. Listen for the “lub-dub” of normal heart sounds. These are the S1 and S2 heart sounds. You may need to adjust your stethoscope a bit to the right or left, or down to the sixth intercostal space to account for normal anatomical variances or serious heart disease.
  7. Once you regularly hear the pulse, note the second and begin counting the beats (“lub” or “dub”, not both, as they are parts of the same beat), for one full minute.
  8. Observe if the pulse rhythm is regular or irregular, such as occasionally or regularly skipped beats or delays between “lub” and “dub” on some beats.
  9. Replace the patient’s clothing and bed covers.
  10. Perform hand hygiene and clean the bell of your stethoscope with an alcohol swab.
  11. Document the pulse rate and pattern in the patient’s record, and inform the nurse of any rate or rhythm abnormality or significant change from the previous measurement per institutional or unit protocol.

Axillary Temperature with Electronic Thermometer

Compared to other temperature measurement methods, the axillary measurement is considered the least reliable. An axillary temperature measurement typically reads 0.5 to 1 degree Fahrenheit lower than an oral temperature reading [1]. For this reason, it is recommended to use this method only when other methods are contraindicated or when taking an axillary temperature is the safest method for the patient.

Measuring the Radial Pulse

The radial artery, located in the wrist, is easy to feel and an efficient location to measure heart rate. Changes to the rhythm or strength of the radial pulse can indicate heart disease, damage to the arm, or body fluid status. It is important to remember to check the radial pulse on both sides as differences between left and right can indicate injury or disease processes.

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.

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.

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.

Assisting the Resident to Transfer from the Bed to a Chair or Wheelchair

It is important to remember on which side to place the chair when assisting a patient in transferring. Putting the chair on the resident’s unaffected side allows the resident to lead with his or her strong extremity. This eases the procedure for the resident and reduces the risk of falling.
