USMLE Sample Questions: Types & Examples

Step 1

One of the most common formats for step 1 is a Single-Best-Answer Question. It is linked to a single question with four or more response possibilities (for example, A, B, C, D, and E). You can go through the USMLE Step 1 practice questions to gain a better understanding of the exam.

Several questions require you to interpret graphic or graphical materials. You must choose the best response to the question. Other possibilities may be partially correct, but only one best solution exists. This is the most common and standard multiple-choice question structure on the exam.

Step 2

For Step 2, these are the most common formats:

• Patient scenarios can be presented in either a Vignette (paragraph) or Chart/Tabular format for any Single Item or Sequential Item Set. The chart/tabular form of test items is intended to mirror patient charts but not to be an exact copy of a patient chart. 
• A patient-centered vignette is linked to a single question with four or more response possibilities.
• A sequential item set can be linked to two or three questions about the information delivered. Each question is related to the first patient scenario but tests a different point. 
• The abstract item format comprises a summary of an experiment or clinical inquiry provided in a way that a physician is likely to encounter, such as an abstract accompanying a research report in a medical journal.

Step 3

Patient scenarios, pharmaceutical commercials, and abstracts are among the multiple-choice question forms in Step 3.

Computer-based case simulations are interactive simulations of a patient-care situation designed to assess your clinical management approach, including diagnosis, treatment, and monitoring.

USMLE Step 1 Sample Questions 

Here are some USMLE  step 1 practice questions to help you prepare well for the exam:

A 27-year-old lady visits the office for preconception counseling. She claims that a friend recently gave birth to a baby with a neural tube defect and wants to reduce her chances of having a child with this issue.

(E) Triglyceride lipolysis

(Answer: A)

Sample Question From Step 2

A 10-year-old kid is brought in for a follow-up exam two days after being treated in the emergency room for hives, hoarseness, and light-headedness. His symptoms started 15 minutes after he was stung by a bee and lasted around 60 minutes before he was treated.
