Immunology Practice Test 8
Immunology NCLEX Practice Test
Immunology is a key topic within the NCLEX test plan, located under Nursing Science → Clinical Foundations → Immunology. This section covers immune defense, hypersensitivity, and immunotherapy monitoring within nursing scope. Each test contains 50 questions designed to mirror the difficulty and variety of the real exam.
This is the 8th part of the Immunology series. To explore all practice tests under this topic, use the “Back to Main Topic” button at the end of the page.

It’s a perfect space to reinforce challenging topics and sharpen your recall through quick, focused repetitions. Short, powerful, and repeatable!
Immunology Practice Test 8
A client is brought to the emergency unit with chest tightness and audible wheezing after exposure to pollen. Which antibodies are responsible for this presentation?
- Ig G
- Ig A
- Ig E
- Ig M
Explanation: Answer reason: Allergen cross-linking of IgE triggers degranulation with histamine and leukotrienes, causing bronchoconstriction, mucus production, and wheezing. This mechanism best explains acute chest tightness and audible wheeze after allergen exposure. IgG is more associated with secondary immune responses and some type II/III hypersensitivity processes rather than classic atopy/asthma. IgA is primarily mucosal protection and IgM is an early-response antibody, neither of which drives immediate allergic bronchospasm.
Which blood cells are involved in immune response?
- Red blood cells
- White blood cells
- Platelets
- Plasma cells
Explanation: Answer reason: Neutrophils and macrophages provide rapid phagocytic defense, while lymphocytes (T cells and B cells) drive antigen-specific immunity and immunologic memory. Red blood cells mainly transport oxygen and carbon dioxide and do not perform immune surveillance or effector functions. Platelets primarily function in hemostasis, and plasma cells are differentiated B lymphocytes rather than the broad blood-cell category responsible for overall immune responses.
