Skin Care and Positioning on the CNA Exam: Preventing Pressure Injuries

The nurse aide's part in pressure injury prevention

Pressure injuries develop where skin and the tissue under it are squeezed for too long, usually over bony areas. Preventing them takes a whole team, but nurse aides see residents' skin more often than anyone else. The Agency for Healthcare Research and Quality (AHRQ) says it directly in its pressure ulcer prevention toolkit: nursing assistants can be taught to check the skin any time they are cleaning, bathing, or turning a patient, and they need to feel comfortable reporting any suspicious area.

That is exactly how the CNA exam frames it. Skin care, transfers, positioning, and turning are personal care skills in the federal training curriculum, and the right answer in a skin question is almost always to observe carefully, keep the skin protected, and tell the nurse. Once that pattern is clear, practice CNA skin care and positioning questions with explanations →.

What to look at, and what to report

AHRQ lists the usual elements of a skin assessment as temperature, color, moisture, turgor, and skin integrity, meaning whether the skin is intact or has open areas or rashes. A nurse does the full assessment; you notice changes during routine care and report them.

Pay special attention to:

• pressure points AHRQ tells staff to check during routine care: the back of the head for residents on bed rest, the shoulders, back, and tailbone area (sacrum and coccyx) when turning, the heels and feet, and the arms and elbows
• skin under devices, including oxygen tubing (check the ears), urinary catheters, splints, and compression stockings, which AHRQ says should be removed to check the skin beneath
• skin folds and moist areas, because AHRQ warns that moisture-associated skin damage can be confused with a pressure injury

Report what you see, not a diagnosis. "There's a red area on her left heel that didn't fade after I repositioned her" is a useful report. "She has a stage 2 ulcer" is a nurse's judgment.

Keeping skin healthy during routine care

• Clean and dry. Clean the skin promptly after incontinence and dry it gently, especially in folds.
• Smooth linens. Wrinkles, crumbs, and objects in the bed add pressure and friction.
• Lift, don't drag. Moving a resident by sliding them across the sheet can damage fragile skin. Use the lift sheet or method your facility trains you on, with help when needed.
• Reposition on schedule. Turning intervals are set in each resident's care plan. Follow that schedule and tell the nurse if a resident refuses or can't tolerate a position.
• Protect your own view of the skin. Minimize exposure for dignity, but don't skip looking.

The side-lying position: principles behind the skill

"Positions on Side" is one of the 23 NNAAP skills. Tennessee's version, titled "Positions On Client's Right Side," was updated for testing that begins November 1, 2026. Without copying any checklist, the principles it tests are worth knowing for the written exam too:

Original practice question. While repositioning a resident, a nurse aide notices a red area on the resident's hip that does not fade after a few minutes off pressure. What should the aide do?

• A. Massage the red area firmly to improve circulation
• B. Apply lotion and check again tomorrow
• C. Keep pressure off the area and report it to the nurse
• D. Cover it with a bandage

Answer: C. A red area that persists is a change to report, and keeping pressure off it protects the tissue until the nurse assesses it. Massaging it (A), applying lotion and waiting (B), or bandaging it (D) are all treatment decisions the aide makes without the nurse, and B also delays the report by a day.

Common traps in skin and positioning questions

• Treating the area yourself, with massage, creams, or dressings the nurse hasn't ordered.
• Waiting to report until a red area becomes an open sore.
• Leaving devices in place without checking the skin underneath when you're asked to.
• Choosing your own turning schedule instead of the care plan's.
• Forgetting fall safety after repositioning: bed low, call light within reach.

Skin care overlaps with mobility. The range of motion guide and the fall prevention guide cover the movement side of the same residents.
