This pattern of scarring is caused by impaired:
a. nutritional status.
b. collagen synthesis.
c. epithelialization.
d. contraction.

Answer to Question 1

ANS: B
Impaired production of collagen can cause surface overhealing, leading to a keloid or a hyper-trophic scar. Nutritional deficiencies would lead to healing problems, but not extended scarring. Necrosis or steroid use leads to impaired epithelialization. Impaired contraction would lead to drawing of tissues, not raised.

Answer to Question 2

ANS: B
Eosinophils serve as the body's primary defense against parasites. Monocytes and neutrophils are phagocytic. Macrophages are not active against parasites; they act as long-term defense against infections.
