handwashing - Handwashing for CNAs

Handwashing for CNAs

Handwashing is considered the single most important practice to prevent the spread of infection. Even when hands look clean, they could potentially be crawling with dangerous microorganisms and pathogens. Using soap and friction during handwashing helps loosen the oils on the skin, allowing dirt and pathogens to be rinsed away.

Measuring the Apical Pulse - Measuring the Apical Pulse

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.).

Measuring the Radial Pulse 1 - Measuring the Radial Pulse

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.

Tympanic Membrane Temperature 768x512 - Tympanic Membrane Temperature with Electronic Thermometer

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.

Rectal Temperature with Electronic Thermometer - Rectal Temperature with Electronic Thermometer

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.

Axillary Temperature - Axillary Temperature with Electronic Thermometer

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.

Nail Care 768x432 - Nail Care (Fingers and Toes) for CNAs

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.

Perineal Care of the Female Resident 768x432 - Perineal Care of the Female Resident

Perineal Care of the Female Resident

Perineal care should be performed during a bath, after using the bedpan, and/or after incontinence. Proper technique is important for maintaining hygiene, preventing infection, and avoiding skin breakdown. Because of the close proximity between a woman’s urethra, vagina, and anus, it is essential to only wipe in a front to back motion. Wiping in the opposite direction is associated with a greater risk for developing a urinary tract infection.

Partial Bed Bath 768x432 - Partial Bed Bath

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.

Sim’s Position 1 768x305 - Sim's Position

Sim’s Position

The position a patient is placed in is often ordered by the physician, or recommended by a speech, occupational, or physical therapist. The position dictates whether a patient is sitting, lying, standing; or if they are on their side, back, or prone (face-down). Positioning is also determined by the patient’s current needs, such as: Are they eating? Sleeping? Having surgery on their back? Are they receiving nutrition through a nasogastric tube?

Moving the Resident to the Side of the Bed - Moving the Resident to the Side of the Bed

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.

Supine Position 768x512 - Supine Position

Supine Position

Supine position is a natural and comfortable position for most people. For this reason, it is a highly utilized position for nursing procedures. Unfortunately, this position puts pressure on many bony prominences that can lead to discomfort and/or pressure ulcers if the pressure is not relieved every so often (typically every two hours or less).

Read More
Prone Position 768x512 - Prone Position

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.

Transferring the Resident from a Bed with a Mechanical Lift

A mechanical lift is used to transfer residents who cannot support their own weight. When used properly, mechanical lifts prevent injuries for both residents and health care workers. It is important that a nurse’s assistant be trained to use the mechanical lift before attempting to operate it. Most facilities require at least two health care workers to assist when using a mechanical lift.

Assisting the Resident to Sit on the Side of the Bed

Having the resident sit on the side of the bed is otherwise referred to as dangling. When a resident quickly changes position, especially from lying to sitting or standing, there can be a rapid drop in the resident’s blood pressure. This drop in blood pressure may cause dizziness or lightheadedness.

Offering the Bedpan - Offering the Bedpan

Offering the Bedpan

When a resident is bed-bound, they must use a bedpan to urinate and defecate. This can be embarrassing for the resident, so it should be done with sensitivity to the resident’s privacy and dignity. There are two types of bedpans. A regular bedpan is the deeper and more rounded of the two. A fracture pan has a relatively flat upper end with a trough at the lower end. Fracture pans are used for residents who have difficulty, or restrictions against, moving their hips and/or backs.

Feeding the Patient 768x432 - Feeding the Patient

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.

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.

Indwelling Catheter Care

Indwelling catheters allow urine to drain from the bladder. They are used when residents are unable to urinate on their own or when the process of cleaning the resident after urination would be difficult for the resident to tolerate (such as during end of life care). Caring for the catheter appropriately is a vital part of preventing infection and skin breakdown.
