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.

  1. Gather your supplies:
    • Gloves
    • Graduated measuring container. Make sure that the measurement on the container reflects the accuracy required by the doctor or institutional policy.
    • Antiseptic wipes
    • Paper towels or an absorbent pad
  2. Give the resident privacy by closing the door or curtain.
  3. Perform hand hygiene and don gloves.
  4. Lay the paper towels or absorbent pad on the floor below the urinary drainage bag.
  5. Place the measuring container on the towels or pad.
  6. Without allowing the drain to touch any part of the measuring container, open the drain and allow all urine to drain into the container.
  7. Clamp the drain and clean the end with an antiseptic wipe. Place the drain back in its holder.
  8. Note the amount of urine in the container. Note the characteristics of the urine. What is the color? Is there sediment or blood present? Does it smell strongly? Is there a decrease or increase in the amount of urine versus the last time the bag was emptied?
  9. Remove the paper towel or absorbent pad.
  10. Pour the urine into the toilet and rinse the measuring container. Pour the rinse water into the toilet and flush.
  11. Disinfect and store or dispose of the measuring container.
  12. Remove gloves and perform hand hygiene.
  13. Record the quantity and characteristics of the urine in the appropriate section of the resident’s chart per institutional or unit policy. Report any changes to the nurse per policy.

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.

Logrolling the Resident

Logrolling is a technique used to roll a resident onto their side without the resident helping, and while keeping the resident’s spine in a straight line. This is especially important for residents who have had spinal surgery or injury.

Putting on Personal Protective Equipment

Personal protective equipment is worn to protect the mouth, nose, eyes, clothing, and skin from unwanted pathogens. In the health care setting, a patient’s condition often prompts the use of personal protective equipment; however, a health care worker is able to wear personal protective equipment whenever he or she deems it is necessary (e.g., during procedures with the potential for excessive contact with bodily fluids).

Measuring Blood Pressure

Many factors can interfere with obtaining an accurate blood pressure. The most common mistakes that lead to inaccurate blood pressures are a result of improper technique, including: not supporting the patient’s arm, using the wrong sized cuff, positioning the cuff too low on the patient’s arm, improper positioning of the cuff’s artery marker, and attempting to measure blood pressure through clothing.

Measuring the Apical Pulse

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.).

Nail Care (Fingers and Toes) for CNAs

Nail care of both the feet and the hands should be performed as part of the patient’s daily hygiene routine. The status of the patient’s nails can reflect their overall health. Nail issues can also lead to infection that can spread systemically (ex, ingrown nails or fungus). You should never clip a patient’s nails with nail clippers, and always review your institution’s policy about what nail care is allowed.
