A) Inflammatory phase B) Proliferative phase C) Maturation phase D) Hemostasis phase Answer: B) Proliferative phase Rationale: During the proliferative phase, granulation tissue forms, and new blood vessels appear to support tissue repair. Which risk factor is most likely to contribute to the development of pressure injuries in an immobile patient? A) Impaired sensory perception B) Increased mobility C) High-protein diet D) Good nutritional status Answer: A) Impaired sensory perception Rationale: Patients with impaired sensory perception are unable to feel pressure or discomfort, making them more susceptible to pressure injuries. Which of the following is a common cause of shear-related pressure injuries? A) Sliding down in bed with the head of the bed elevated B) Immobility in a sitting position C) Inadequate nutrition D) Chronic illness Answer: A) Sliding down in bed with the head of the bed elevated Rationale: Shear injuries occur when the skin remains in place while underlying tissues move, commonly caused by sliding down in bed with the head elevated.  Which of the following describes the inflammatory response in wound healing? A) Constriction of blood vessels and clot formation B) Migration of white blood cells to the wound site C) Formation of new collagen D) Resurfacing of the wound with new epithelial cells Answer: B) Migration of white blood cells to the wound site Rationale: During the inflammatory phase, white blood cells migrate to the wound site to fight infection and begin the healing process.
