Step 1 First Aid Rapid Review: 1076
Questions and Verified Answers | 100%
Correct | Grade A (2026/2027)
This "Rapid Review" section at the end of First Aid for the USMLE Step 1 is a highly condensed, high-yield
compilation designed for final review, containing over 1,000 classic clinical vignettes, associations, and
lab findings. This specific 1076-question version referenced is a popular student-curated set
that mirrors the Rapid Review section of First Aid, covering pathology, microbiology, pharmacology, and
classic disease presentations.
Key Characteristics of the 1076 Rapid Review
• Active Recall Focus: Cards are structured to show a clinical scenario/finding and require
naming the diagnosis.
• Structure: It focuses on high-yield "classic" presentations, such as "Achilles tendon Xanthoma"
leading to "Familial Hypercholesterolemia".
• Content Mix: Covers major organ systems, including cardiovascular, endocrine, neurology, and
renal, along with key pharmacological agents.
• Usage: Best utilized in the final 1–2 weeks before the exam (the "dedicated" period) for rapid
pattern recognition.
Examples of 1076 Rapid Review Content
• Diagnosis: Budd-Chiari Syndrome (post-hepatic venous thrombosis). Scenario: Abdominal
pain, ascites, hepatomegaly.
• Diagnosis: Waterhouse-Friedrichsen syndrome. Scenario: Adrenal hemorrhage, hypotension,
DIC.
• Diagnosis: Crohn's Disease. Scenario: Alternating areas of transmural inflammation and
normal colon (skip lesions).
• Diagnosis: Wernicke encephalopathy. Scenario: Atrophy of the mammillary bodies (thiamine
deficiency).
• Diagnosis: IgA deficiency. Scenario: Anaphylaxis and/or angioedema following blood
transfusion.
