A 30-year-old male was involved in a motor vehicle accident. The glass from the shattered win-dow cut his face and neck. The scar, however, was raised and extended beyond the original boundaries of the wound.
 
  This pattern of scarring is caused by impaired:
  a. nutritional status.
  b. collagen synthesis.
  c. epithelialization.
  d. contraction.

Question 2

A 10-year-old male is diagnosed with a parasite. Which lab result should the nurse check for a response to the parasite?
 
  a. Monocytes
  b. Eosinophils
  c. Neutrophils
  d. Macrophages

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.
