Which client is at greatest risk for developing a pressure injury?

Rationale: A. A client who exercises daily is at low risk for pressure injuries. Regular movement promotes adequate circulation, reduces prolonged pressure on any one area, and maintains skin integrity. Activity is actually protective against pressure injury development. B. An immobile client is at the greatest risk for pressure injuries. Pressure injuries develop when there is prolonged pressure over bony prominences (e.g., sacrum, heels, hips), which impairs blood flow and leads to tissue ischemia and breakdown. Immobility prevents repositioning, resulting in sustained pressure, decreased perfusion, and eventual tissue damage. Additional contributing factors often include moisture, friction, shear, and poor nutrition, but immobility is the primary and most significant risk factor. C. A client with a mild headache has no direct risk for pressure injury unless other factors (like immobility) are present. A headache does not affect circulation, mobility, or skin integrity. D. A client with seasonal allergies is not at increased risk for pressure injuries. Allergies may cause discomfort or respiratory symptoms but do not impair mobility or tissue perfusion in a way that contributes to pressure injury formation.
