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.
A clinic nurse is caring for a patient admitted with AIDS. The nurse has
assessed that the patient is experiencing a progressive decline in cognitive,
behavioral, and motor functions. The nurse recognizes that these symptoms
are most likely related to the onset of what complication?
A) HIV encephalopathy
B) B-cell lymphoma
C) Kaposis sarcoma
D) Wasting syndrome - ANSWER: A) HIV encephalopathy
HIV encephalopathy is a clinical syndrome characterized by a progressive
decline in cognitive, behavioral, and motor functions. The other listed

support. The nurse should respond with an open-ended question to help the
patient to identify fears about being diagnosed with a life-threatening chronic

Immediate deferral to spiritual care is not a substitute for engaging with the
patient. The nurse should attempt to foster hope, but not in a way that
downplays the patients expressed fears.
A nurse is working with a patient who was diagnosed with HIV several
months earlier. The nurse should recognize that a patient with HIV is
considered to have AIDS at the point when the CD4+ T-lymphocyte cell
count drops below what threshold?
A) 75 cells/mm3 of blood
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
When CD4+ T-cell levels drop below 200 cells/mm3 of blood, the person is said to
have AIDS

A patient with a family history of allergies has suffered an allergic response
based on a genetic predisposition. This atopic response is usually mediated by
what immunoglobulin?
A) Immunoglobulin A
B) Immunoglobulin M
C) Immunoglobulin G
D) Immunoglobulin E - ANSWER: D) Immunoglobulin E
Atopy refers to allergic reactions characterized by the action of IgE
antibodies and a genetic predisposition to allergic reactions.
A patient has developed severe contact dermatitis with burning, itching,
