ANS: B
Most of the factors that interfere with the production of collagen in healing tissues are
nutritional. 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.
Vitamin D deficiency will not directly affect healing; ascorbic acid does.
Melanin deficiency will not directly affect healing; ascorbic acid does.
Cholesterol deficiency will not directly affect healing; ascorbic acid does.
MULTIPLE RESPONSE
1. A nurse remembers the primary actions of the complement cascade include (select all
that apply):
a. Increased vascular permeability
b. Vasoconstriction
c. Chemotaxis
d. Opsonization
e. Cell killing
f. Increased clotting
ANS: A, C, D, E
The actions of the complement cascade include increased vascular permeability and
vasodilation, chemotaxis, opsonization, and cell killing. It does not involve
vasoconstriction or increased clotting.
2. The nurse is assessing a patient with a diagnosis of inflammation. The nurse would
expect to find which of the following signs and symptoms consistent with acute
inflammation? (Select all that apply.)
a. Heat
b. Erythema
c. Pain
d. Swelling
e. Exudates
f. Loss of function
ANS: A, B, C, D, F
The classic symptoms of acute inflammation include redness (erythema), heat, swelling,
pain, and loss of function. Exudates would indicate infection, not inflammation.
3. The nurse identified each of the following clinical manifestations of inflammation.
Which would the nurse classify as a local response? (Select all that apply.)
a. Fever
b. Redness
c. Swelling
d. Heat
e. Pain

ANS: B, C, D, E
Local manifestations of inflammation are the result of the vascular changes associated
with the inflammatory process, including vasodilation and increased capillary
permeability. The symptoms include redness, heat, swelling, and pain.
4. Physical barriers that offer the body protection from damage and infection are located
in the (select all that apply):
a. Gastrointestinal tract
b. Genitourinary tract
c. Respiratory tract
d. Lymph system
e. Hematopoietic system
ANS: A, B, C
The physical barriers that cover the external parts of the human body offer considerable
protection from damage and infection. These barriers are composed of tightly associated
epithelial cells of the skin and of the linings of the gastrointestinal, genitourinary, and
respiratory tracts.

1. Neutrophils:
a. are phagocytic cells.
b. produce histamine.
c. produce antibodies.
d. are elevated during an allergic response.
