A patients injury has initiated an immune response that involves
inflammation. What are the first cells to arrive at a site of inflammation?
A) Eosinophils
B) Red blood cells
C) Lymphocytes
D) Neutrophils - ANSWER: D) Neutrophils
Neutrophils are the first cells to arrive at the site where inflammation occurs.
Eosinophils increase in number during allergic reactions and stress responses,
but are not always present during inflammation. RBCs do not migrate
during an immune response.
Lymphocytes become active but do not migrate to the site of inflammation.
A nurse is admitting a patient who exhibits signs and symptoms of a
nutritional deficit. Inadequate intake of what nutrient increases a patients
susceptibility to infection?
A) Vitamin B12
B) Unsaturated fats
C) Proteins
,2|Page
D) Complex carbohydrates - ANSWER: C) Proteins
Depletion of protein reserves results in atrophy of lymphoid tissues,
depression of antibody response, reduction in the number of circulating T
cells, and impaired phagocytic function. As a result, the patient has an
increased susceptibility to infection. Low intake of fat and vitamin B12affects
health, but is not noted to directly create a risk for infection. Low intake of
complex carbohydrates is not noted to constitute a direct risk factor for
infection.

B) 200 cells/mm3 of blood
C) 325 cells/mm3 of blood
D) 450 cells/mm3 of blood - ANSWER: B) 200 cells/mm3 of blood
