24. 2. Poorly controlled diabetes is a serious risk factor for postoperative wound infection. Other factors that delay wound healing include advanced age, nutritional deficiencies (vitamin C, protein, zinc), inadequate blood supply, use of corticosteroid, infection, mechanical friction on the wound, obesity , anemia, and poor general health.
36. 3. When assessing a client with dark skin, the nurse should observe for skin that is darker, brownish, purplish, or bluish compared to surrounding skin. Fluorescent light casts a blue light, making skinassessment difficult; natural or halogen light sources help to accurately assess the skin . Risk assessment using the Braden Scale should be performed on all clients. A Braden score of 12 indicates a high risk for pressure ulcer, and the lower the Braden score, the higher the risk (no risk 19 to 23, at risk 15 to 18, moderate risk 13 to 14, high risk 10 to 12, and very high risk 9 or below). The nurse should touch the skin to assess consistency and temperature differences.
42. 1, 2, 3, 5, 6. Risk factors associated with skin cancer include age, exposure to chemical pollutants , exposure to the sun , genetics, and immunosuppression. As individuals age, the risk of developing skin cancer increases. Long-time exposure to the sun and exposure to chemical pollutants (nitrates, coal , tar, etc.) increases the risk of skin cancer. Individuals who have less skin pigmentation (ie, fair, blue-eyed people) have a higher risk of skin cancer because they tend to incur sunburns rather than tan. Family history plays a role in cancer. Regardless , immunosuppressed individuals are at a higher risk for the development of any type of cancer, as the body's defenses are not functioning properly.
