Sample Questions and Answers

Question 1. A 24-year-old woman develops generalized urticaria, wheezing, hypotension, and lip swelling within minutes of eating peanuts. What is the most appropriate initial treatment?

A. Oral diphenhydramine

B. Intramuscular epinephrine

C. Intravenous corticosteroids

D. Nebulized albuterol only

Correct Answer: B. Intramuscular epinephrine

Explanation:
Intramuscular epinephrine is the first-line treatment for anaphylaxis and should be administered immediately when anaphylaxis is suspected. Delaying epinephrine increases the risk of respiratory failure, cardiovascular collapse, and death. Although antihistamines, corticosteroids, and bronchodilators may be used as adjunctive therapies, they should never replace epinephrine. Candidates taking the American Board of Allergy and Immunology (ABAI) exam should recognize the prompt diagnosis and emergency management of anaphylaxis as a high-yield topic.

Question 2. Which immunoglobulin is primarily responsible for mediating immediate (Type I) hypersensitivity reactions?

A. IgA

B. IgG

C. IgE

D. IgM

Correct Answer: C. IgE

Explanation:
Immunoglobulin E (IgE) binds to mast cells and basophils. Upon re-exposure to an allergen, cross-linking of allergen-specific IgE triggers the release of histamine and other inflammatory mediators, resulting in allergic symptoms such as urticaria, allergic rhinitis, asthma, or anaphylaxis. Understanding the immunologic mechanisms underlying allergic disease is essential for diagnosing and managing hypersensitivity disorders and is a core competency tested on the ABAI certification exam.

Question 3. A patient with moderate persistent asthma continues to experience symptoms despite daily low-dose inhaled corticosteroid therapy. According to current asthma management principles, the next appropriate step is to:

A. Discontinue inhaled corticosteroids.

B. Increase therapy by adding a long-acting beta₂-agonist (LABA) or stepping up controller treatment.

C. Prescribe antibiotics indefinitely.

D. Use only a short-acting beta₂-agonist as needed.

Correct Answer: B. Increase therapy by adding a long-acting beta₂-agonist (LABA) or stepping up controller treatment.

Explanation:
When asthma remains uncontrolled despite appropriate adherence and inhaler technique, treatment should be stepped up according to evidence-based asthma guidelines. This often includes adding a LABA to an inhaled corticosteroid or increasing controller therapy, depending on the patient’s clinical status. Before escalating treatment, clinicians should confirm medication adherence, proper inhaler technique, and evaluate environmental triggers or comorbid conditions contributing to poor asthma control.

Question 4. Which patient is the best candidate for allergen immunotherapy?

A. A patient with seasonal allergic rhinitis whose symptoms remain uncontrolled despite appropriate medications and allergen avoidance

B. A patient with an acute bacterial pneumonia

C. A patient with viral pharyngitis

D. A patient with asymptomatic food sensitization only

Correct Answer: A. A patient with seasonal allergic rhinitis whose symptoms remain uncontrolled despite appropriate medications and allergen avoidance

Explanation:
Allergen immunotherapy is indicated for patients with IgE-mediated allergic diseases, such as allergic rhinitis or allergic asthma, whose symptoms persist despite pharmacologic treatment and environmental control measures. Immunotherapy modifies the immune response over time and can significantly reduce symptom severity and medication requirements. Appropriate patient selection, contraindications, and monitoring are important concepts commonly evaluated on the ABAI board examination.

Question 5. A child has recurrent sinopulmonary infections, chronic otitis media, and markedly reduced serum IgG levels. Which diagnosis should be considered first?

A. Selective IgA deficiency

B. Primary immunodeficiency disorder

C. Seasonal allergic rhinitis

D. Chronic urticaria

Correct Answer: B. Primary immunodeficiency disorder

Explanation:
Recurrent, severe, or unusual infections—particularly involving the respiratory tract—combined with low immunoglobulin levels should raise suspicion for a primary immunodeficiency disorder. Early recognition is critical because delayed diagnosis may result in permanent organ damage and recurrent complications. Physicians should evaluate quantitative immunoglobulin levels, vaccine antibody responses, lymphocyte function, and other immune studies when clinically indicated. Recognition and management of primary immunodeficiency disorders are major topics on the ABAI certification exam.

Description

Preparing for the American Board of Allergy and Immunology (ABAI) Certification Exam requires an in-depth understanding of allergic diseases, clinical immunology, asthma management, immunodeficiency disorders, hypersensitivity reactions, diagnostic testing, and evidence-based patient care. Whether you are completing fellowship training or preparing for board certification, practicing with realistic exam-style questions is one of the most effective ways to reinforce your knowledge and improve your readiness for the examination.

This American Board of Allergy and Immunology (ABAI) Exam Practice Questions and Answers resource is designed to help physicians prepare with comprehensive multiple-choice questions, detailed answer explanations, and content aligned with the major domains tested on the board exam.

Prepare with Confidence for the ABAI Certification Exam

The American Board of Allergy and Immunology certification demonstrates advanced expertise in diagnosing, treating, and managing allergic, immunologic, and respiratory disorders. Board-certified allergists and immunologists are expected to apply current clinical guidelines, interpret diagnostic studies, manage complex immune-mediated conditions, and provide evidence-based patient care.

Consistent practice with realistic board-style questions helps strengthen clinical reasoning, improve diagnostic accuracy, and build the confidence needed to perform well on exam day.

Why Choose This ABAI Practice Test?

A high-quality practice test allows you to evaluate your current knowledge while identifying areas that require additional study before taking the certification examination.
