6.1 Positioning, Alignment, and Pressure Injury Prevention
Key Takeaways
- Good positioning keeps the resident in natural body alignment, protects joints, supports breathing and circulation, and reduces pressure on bony prominences.
- Pressure injury prevention depends on frequent observation, scheduled repositioning (commonly every 2 hours in bed and every 1 hour in a chair), clean dry skin, nutrition and hydration support, and prompt reporting.
- Use pillows, wedges, heel protectors, and facility-approved devices to support the body; never leave a resident resting directly on tubing, wrinkles, or hard edges.
- Report redness that does not blanch, pain, warmth, open areas, blisters, drainage, new swelling, or a resident who cannot tolerate a position; never massage a reddened bony area.
Positioning Is Preventive Care
Positioning means placing and supporting the resident so the head, spine, hips, shoulders, arms, legs, and feet stay as close to normal alignment as the resident can tolerate. The goal is not to make every resident look identical. The goal is to follow the care plan, protect weak or painful body parts, prevent avoidable strain, and help the resident breathe, rest, eat, move, and interact safely. On the Texas clinical skills test, Positioning a Resident on the Side (lateral position) is one of the randomly assigned skills, so the candidate must know support points cold.
A resident who slides down in bed may look comfortable for a moment, but the body is usually under stress. The neck may be flexed, the hips pulled forward, the heels pressed into the mattress, and the skin over the tailbone sheared. Shearing happens when skin stays against a surface while the deeper tissue slides in the opposite direction. Friction is the surface rubbing of skin against linen. Both damage tissue, often before the skin ever opens. Raising the head of the bed above 30 degrees increases sliding and shear over the sacrum, which is why prolonged high-Fowler's without a knee support is a common trap.
Alignment Check
| Area | What to check | Why it matters |
|---|---|---|
| Head and neck | Head supported, chin not forced to chest | Helps breathing, swallowing, and comfort |
| Shoulders and hips | Body not twisted, shoulders and hips stacked in line | Reduces strain and sliding |
| Arms and hands | Weak arm supported on a pillow, fingers not trapped | Prevents pain, swelling, and contracture |
| Knees and ankles | Slight knee support when ordered, ankles neutral | Limits joint stress and footdrop |
| Heels and elbows | Bony areas floated or padded per care plan | Reduces pressure injury risk |
| Tubes and linens | No tubing, call-light cord, crumbs, or wrinkles under skin | Prevents device-related pressure and breakdown |
Common positions include supine, lateral, Sims', Fowler's, semi-Fowler's, and chair sitting. Supine is lying on the back. Lateral is lying on the side. Sims' is a side-lying position with the upper leg flexed and supported. Fowler's raises the head of the bed (commonly 45-60 degrees) for breathing, eating, or comfort; semi-Fowler's is roughly 30 degrees. For side-lying, place a pillow behind the back for support, one between the knees to keep hips aligned, and support the upper arm so the shoulder is not pulled. Any position becomes unsafe if the resident slides, twists, or rests too long on one area.
Pressure injuries form over bony prominences. High-risk areas include the back of the head, ears, shoulders, spine, elbows, sacrum, coccyx, hips, knees, ankles, and especially the heels. A wheelchair user also needs attention to the buttocks, tailbone, shoulder blades, elbows, and backs of the thighs. A device meant to help -- oxygen tubing, a urinary drainage tube, a brace, or a wheelchair footrest -- can create a device-related pressure injury when it presses into skin.
The nurse and care plan set the turning schedule. A common standard is repositioning at least every 2 hours when in bed and every 1 hour (with weight shifts every 15 minutes if able) when in a chair, but the exact interval depends on skin risk, diagnosis, mobility, pain, support surface, and orders. The aide does not skip turns because a resident is asleep; instead, follow the plan, use gentle communication, and report refusal or intolerance.
Before repositioning, explain what you will do, provide privacy, wash hands, raise the bed to working height if allowed, lock the bed wheels, and use good body mechanics. Ask the resident to help -- bending a knee, holding an assist bar when allowed, or turning the head supports independence and makes the move safer. Move the resident without dragging. Use lift sheets, draw sheets, slide sheets, or a second staff member as the care plan requires. Pulling on arms, shoulders, or under the armpits can dislocate a shoulder or tear skin.
If the resident is heavy, weak, unable to follow directions, or attached to equipment, get help before the move.
After positioning, lower the bed, place the call light within reach, confirm personal items are accessible, and make sure the resident is not pressed against a side rail. Use side rails only as the care plan and facility policy direct -- improper rail use can become entrapment or an unauthorized restraint. Skin observation is part of every bath, brief change, repositioning, and transfer. Look for redness that does not fade after pressure is relieved (non-blanchable erythema, an early Stage 1 sign), warmth, swelling, pain, blisters, open skin, drainage, or odor.
In residents with darker skin tones, early injury may show as color change, warmth, firmness, bogginess, or pain rather than bright redness.
Keep skin clean and dry, but do not scrub fragile skin and never massage a reddened bony area -- it can deepen tissue damage. Moisture from urine, stool, sweat, drainage, or spills raises risk; change wet linens promptly and apply barrier products only as directed. Nutrition and hydration matter because skin cannot repair without protein and fluid, so encourage allowed meals and fluids and report poor intake.
Report Immediately
Report any open area, blister, new drainage, bleeding, unusual odor, non-blanching redness, sudden pain, new numbness, swollen limb, refusal of turns, or equipment that no longer fits. Also report repeated sliding, inability to maintain alignment, or a resident who says a position causes shortness of breath. Early reporting lets the nurse reassess the care plan before harm increases.
A resident who needs help turning is found on her back with the head of the bed raised. She has slid toward the foot of the bed, and the skin over her tailbone looks red. What should the nurse aide do first?
During a brief change, a nurse aide notices that oxygen tubing has left a deep mark behind the resident's ear. The skin is tender but not open. Which action best protects the resident?
A resident with left-sided weakness is placed in a side-lying position. His weak arm is hanging forward without support, and his top knee is resting directly on the lower knee. What is the best correction?
