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?

Equally important to correct positioning is correct body alignment. Correct alignment prevents undue strain on any joints, bones, muscles, tendons, or ligaments. It also helps prevent pressure ulcers in patients who have limited mobility. For proper body alignment:

The head, neck, and spine should be in a straight line.
The hips should be in line with the back.
The arms and legs should be relaxed.

Sim’s position is comfortable for patients when they wish to sleep or relax while lying on their stomachs.

Achieving Sim’s Position

Start with the patient lying supine (flat on their back) with the body in proper alignment.
Stand on the side of the bed opposite the direction the patient will be facing and raise the bed to a comfortable working height. Lower the side rail. Move first the upper trunk (shoulders and chest), then the lower trunk (abdomen and hips) toward you. A draw sheet can be used for this movement. Raise the side rail.
Walk to the other side of the bed (the one the patient will be facing). Lower the side rail.
Bend the patient’s knee that will be on top once the patient is on their side.
On the side that will be on top (away from the mattress), place one hand on the patient’s shoulder and the other hand on the hip and roll the patient toward you until they are lying partially on their abdomen.
Slide the patient’s lower shoulder until it is not under the patient and move the lower arm to the patient’s side.
Place a pillow under the patient’s head to maintain proper alignment.
The patient’s upper arm should be slightly flexed with a pillow supporting it in line with that shoulder.
Place a pillow behind the patient’s back to help them stay in position.
Place a pillow under the slightly bent upper leg to maintain alignment with the hip.
Ask the patient if they are comfortable. Make adjustments as necessary.
Lower the bed back to the lowest position.
Document the position per institutional or unit policy. Report any difficulty getting the patient into position, or maintaining position to the nurse per policy.

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.

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.

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.

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.

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.
