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.

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.

Performing the Heimlich Maneuver

The Heimlich Maneuver, also known as abdominal thrusts, is used to remove an object that is blocking a resident’s airway and preventing air from reaching the lungs. It only takes four to six minutes for brain damage to occur from lack of oxygen, so prompt action is vital.

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.

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.

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.

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.
