Shearing forces-rationale: friction, impaired circulation, localized pressure, and shearing forces are all risk factors of pressure ulcer development; trapeze use reduces shearing forces. shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis) can occur as clients slide down in bed or are pulled up in bed. subcutaneous skin layers adhere to the sheets while deeper layers, muscle, and bone slide in the direction of movement. to reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move him up in bed, and keep the head of the bed no higher than 30 degrees.client needs category: physiological integrityclient needs subcategory: basic care and comfortcognitive level: applicationreference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1196.
