The United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge (CK) is a pivotal exam that medical students and graduates must pass to become licensed physicians in the United States. A Step 2 CK rapid review offers a focused approach to revisiting high-yield topics and sharpening test-taking strategies, making it an essential component of effective exam preparation.
Understanding the USMLE Step 2 CK
The Step 2 CK assesses an examinee’s ability to apply medical knowledge and clinical science for patient care, emphasizing health promotion and disease prevention. A Step 2 CK rapid review enhances preparation by focusing on high-yield topics and core competencies, ensuring efficient recall and application of knowledge, critical for transitioning into unsupervised medical practice.
Exam Structure and Content
The Step 2 exam exam has up to 316 multiple choice questions. For exams on or after May 7, 2026, it is divided into 16 blocks of 30 minutes each, with up to 20 questions per block. The test day is about 9 hours long, including breaks. The exam still measures how well you apply medical knowledge to patient care, with a strong focus on health promotion and disease prevention.
Before May 7, 2026, the exam had eight 60 minute blocks. If your question bank still uses 40 question blocks, practice with 20 questions in 30 minutes instead.

Practice Questions
Creating practice questions that mimic the style and complexity of the USMLE Step 2 CK exam can be a valuable tool for your Step 2 CK review. Here are a few sample questions:
1. A 30-year-old woman presents to the emergency department with 1 day of abdominal pain that started near the umbilicus and moved to the right lower quadrant. She has nausea but no vomiting. Her last menstrual period was two weeks ago. Temperature is 37.8°C (100°F). Examination shows right lower quadrant tenderness with rebound tenderness. Urine hCG is negative. Which of the following is the most likely diagnosis?
- A. Ectopic pregnancy
- B. Appendicitis
- C. Ovarian torsion
- D. Pelvic inflammatory disease
Answer: B
Explanation: Pain that moves from the area around the navel to the right lower quadrant, with low grade fever and rebound tenderness, is classic for appendicitis. A negative hCG makes ectopic pregnancy unlikely.
2. A 3-year-old boy is brought to the clinic by his parents who are concerned about his failure to speak in sentences. They also report that he does not respond to his name, has poor eye contact, and engages in repetitive play. Which of the following is the most likely diagnosis?
- A. Hearing impairment
- B. Autism spectrum disorder
- C. Intellectual disability
- D. Normal variation of development
Answer: B
Explanation: Poor response to his name, poor eye contact, delayed speech and repetitive play are core features of autism spectrum disorder. A hearing test is still part of the early workup to rule out hearing loss.
3. A 7-year-old girl presents with erythematous, indurated, scaly plaques over her earlobes in a symmetric pattern. Her mother reports that the patient recently received a pair of earrings as a birthday present. What is the mechanism of this reaction?
A. Anaphylactic (type I)
B. Cytotoxic (type II)
C. Immune complex-mediated (type III)
D. Cell-mediated/delayed (type IV)
E. Autoimmune disease (type V)
Answer: D. Cell-mediated/delayed (type IV)
Explanation: The patient’s symptoms are consistent with allergic contact dermatitis, commonly caused by nickel in earrings. This reaction is a type IV hypersensitivity, mediated by T-cells responding to the allergen.
4. A 32-year-old woman presents with a 3-month history of fatigue, weight gain, and constipation. Physical examination reveals dry skin and a delayed relaxation phase of deep tendon reflexes. Laboratory tests show elevated thyroid-stimulating hormone (TSH) and low free thyroxine (T4) levels. What is the most likely diagnosis?
A. Graves’ disease
B. Hashimoto’s thyroiditis
C. Subacute thyroiditis
D. Pituitary adenoma
E. Iodine deficiency
Answer: B. Hashimoto’s thyroiditis
Explanation: The patient’s clinical presentation and laboratory findings are indicative of hypothyroidism, most commonly caused by Hashimoto’s thyroiditis, an autoimmune destruction of the thyroid gland.
5. A 65-year-old man with a history of hypertension and smoking presents with sudden onset of severe, tearing chest pain radiating to the back. Blood pressure is 180/110 mmHg in the right arm and 160/100 mmHg in the left arm. A chest X-ray shows a widened mediastinum. What is the most likely diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
E. Tension pneumothorax
Answer: C. Aortic dissection
Explanation: The patient’s symptoms, differential blood pressure in the arms, and widened mediastinum on imaging are classic signs of an aortic dissection.
6. A 24-year-old woman presents with a 2-day history of dysuria, increased urinary frequency, and suprapubic discomfort. She denies fever, flank pain, or vaginal discharge. Urinalysis reveals positive nitrites and leukocyte esterase. What is the most appropriate next step in management?
A. Obtain a urine culture and await results before initiating treatment
B. Start empirical antibiotic therapy for uncomplicated cystitis
C. Perform a pelvic examination
D. Order a renal ultrasound
E. Advise increased fluid intake only
Answer: B. Start empirical antibiotic therapy for uncomplicated cystitis
Explanation: The patient’s presentation is consistent with uncomplicated cystitis. Empirical antibiotic therapy should be initiated without awaiting urine culture results.
7. A 58-year-old man presents with progressive difficulty swallowing solids and liquids over the past few months. He also reports unintentional weight loss. A barium swallow study shows a “bird-beak” appearance of the distal esophagus. What is the most likely diagnosis?
A. Esophageal cancer
B. Achalasia
C. Gastroesophageal reflux disease
D. Esophageal stricture
E. Diffuse esophageal spasm
Answer: B. Achalasia
Explanation: The “bird-beak” appearance on barium swallow is characteristic of achalasia, a condition caused by the failure of the lower esophageal sphincter to relax, leading to dysphagia for both solids and liquids.
8. A 45-year-old woman presents with fatigue, pallor, and shortness of breath on exertion. Laboratory studies reveal hemoglobin 8.2 g/dL, MCV 70 fL, and low serum ferritin. What is the most likely cause of her anemia?
A. Vitamin B12 deficiency
B. Iron deficiency anemia
C. Anemia of chronic disease
D. Sickle cell anemia
E. Thalassemia
Answer: B. Iron deficiency anemia
Explanation: Microcytic anemia (low MCV) with low ferritin is classic for iron deficiency anemia, often due to chronic blood loss or dietary deficiency.
9. A 60-year-old man presents with sudden-onset left-sided weakness and slurred speech that began 90 minutes ago. On examination, he has right gaze preference and left-sided hemiplegia. CT scan shows no hemorrhage. What is the most appropriate next step in management?
A. Begin aspirin therapy immediately
B. Administer IV alteplase if within 4.5 hours of symptom onset
C. Start heparin infusion
D. Schedule carotid endarterectomy
E. Observe and repeat imaging in 24 hours
Answer: B. Administer IV alteplase if within 4.5 hours of symptom onset
Explanation: Acute ischemic stroke within the therapeutic window should be treated with IV thrombolysis unless contraindicated. Early intervention improves functional outcomes.
10. A 28-year-old man presents with polyuria, polydipsia and nocturia. His BMI is 34 kg/m², he has acanthosis nigricans, and his mother has type 2 diabetes. Fasting glucose is 180 mg/dL, HbA1c is 8.5%, and there are no ketones in his urine. What is the most likely diagnosis?
A. Type 1 diabetes mellitus
B. Type 2 diabetes mellitus
C. Diabetes insipidus
D. Secondary diabetes from corticosteroids
E. Maturity-onset diabetes of the young (MODY)
Answer: B. Type 2 diabetes mellitus
Explanation: Adult onset with hyperglycemia, polyuria, and polydipsia, without ketosis, is typical for type 2 diabetes. Insulin resistance and beta-cell dysfunction are the underlying mechanisms.
