Answer to Question 1

ANS: B
A patient with a stage IV pressure ulcer would heal by secondary intention. A surgical wound and a paper cut would heal by primary intention. A patient with a sunburn would heal without needing either primary or secondary intention.

Answer to Question 2

ANS: B
Most of the factors that interfere with the production of collagen in healing tissues are nutrition-al. Scurvy, for example, is caused by lack of ascorbic acidone of the cofactors required for collagen formation by fibroblasts. The results of scurvy are poorly formed connective tissue and greatly impaired healing. Healing is not associated with vitamin D, melanin, or cholesterol.
