Question: Which of the following is an example of active immunity?
Choices:
• A. Injection of pooled gamma globulin
• B. Breast-feeding
• C. Passed from mother to infant via the placenta
• D. Pneumonia vaccine
Answer: D. Pneumonia vaccine
Rationale: Active immunity occurs when the body is exposed to an antigen and produces its
own antibodies. Vaccines stimulate the immune system to develop immunity without
causing disease, making this an example of active immunity. Passive immunity, such as
gamma globulin injections or maternal antibodies, provides immediate but temporary
protection.
Question: A patient's WBC count indicates a shift to the left. What should the nurse assess
for?
Choices:
• A. Leukemia
• B. Weakness
• C. Infection
• D. Immunosuppression
Answer: C. Infection
Rationale: A “shift to the left” refers to an increase in immature neutrophils (band cells) in
the blood, typically seen during acute bacterial infections as the bone marrow responds to
the demand for neutrophils.
,Question: A lab analysis on a child with chronic nasal drainage shows elevated numbers of
eosinophils in the blood. What is the likely cause of the drainage?
Choices:
• A. Bacterial infection
• B. Allergies
• C. Viral infection
• D. Sinus infection
Answer: B. Allergies
Rationale: Elevated eosinophils are commonly associated with allergic reactions. Chronic
nasal drainage with high eosinophils suggests an allergic rather than infectious cause.
Question: A child with ill-fitting shoes develops a vesicle that bursts, releasing clear watery
fluid. How should the school nurse document this drainage?
Choices:
• A. Serous
• B. Vesicular
• C. Purulent
• D. Sanguineous
Answer: A. Serous
Rationale: Serous drainage is clear, watery fluid typically seen in blisters or minor burns.
Purulent drainage is thick and yellow/green, while sanguineous contains blood.
Question: Which of the following specialized cells are primarily associated with the immune
response?
Choices:
• A. Neutrophils
• B. Monocytes
• C. Macrophages
• D. Lymphocytes
, Answer: D. Lymphocytes
Rationale: Lymphocytes, including B and T cells, are central to adaptive immunity. They are
responsible for antibody production (B cells) and cellular immune responses (T cells).
Question: A severe, life-threatening type 1 hypersensitivity reaction is:
Choices:
• A. Angioedema
• B. Urticaria
• C. Anaphylaxis
• D. Hives
Answer: C. Anaphylaxis
Rationale: Type 1 hypersensitivity reactions are IgE-mediated. Anaphylaxis is a rapid,
systemic allergic reaction that can be fatal without immediate treatment. Other options are
milder manifestations of allergic reactions.
Question: What pathophysiologic abnormality underlies systemic lupus erythematosus
(SLE)?
Choices:
• A. Immune deficiency
• B. Type 2 hypersensitivity
• C. Autoimmunity
• D. Immunosuppression
Answer: C. Autoimmunity
Rationale: SLE is an autoimmune disorder in which the immune system attacks the body’s
own tissues, leading to inflammation and organ damage.
Question: Which term best describes the symptoms of petechiae, easy bruising, bleeding
gums, occult hematuria, or retinal hemorrhage?
Choices:
• A. Neutropenia
• B. Leukopenia
