Chapter 32: Skin Integrity and Wound Care

The nurse considers the impact of shearing forces in the development of pressure injuries in clients. Which client would be most likely to develop a pressure injury from shearing forces?

a client sitting in a chair who slides down Shear results when one layer of tissue slides over another layer. Shear separates the skin from underlying tissues. The small blood vessels and capillaries in the area are stretched and possibly tear, resulting in decreased circulation to the tissue cells under the skin. Clients who are pulled, rather than lifted, when being moved up in bed (or from bed to chair or stretcher) are at risk for injury from shearing forces. A client who is partially sitting up in bed is susceptible to shearing force when the skin sticks to the sheet and underlying tissues move downward with the body toward the foot of the bed. This may also occur in a client who sits in a chair but slides down. The client that is most likely to develop a pressure ulcer from shearing forces would be a client sitting in a chair who slides down.

Upon review of a postoperative client's medication list, the nurse recognizes that which medication will delay the healing of the operative wound?

corticosteroids Clients who are taking corticosteroids or require postoperative radiation therapy are at high risk for delayed healing and wound complications. Corticosteroids decrease the inflammatory process, which may delay healing. Antihypertensive drugs, potassium supplements, and laxatives do not delay wound healing.

A nurse is caring for a client who has an avulsion of her left thumb. Which description should the nurse understand as being the definition of avulsion?

Tearing of a structure from its normal position An avulsion involves tearing of a structure from its normal position on the body. Tearing of the skin and tissue with some type of instrument with the tissue not aligned is a laceration. Cutting with a sharp instrument with wound edges in close approximation and correct alignment is an incision. A puncture of the skin is simply a puncture.
