General Surgery for USMLE Step 2 CK: Exam Questions and Preparation
How General Surgery is tested on Step 2 CK and Step 3, the high-yield topics, a preparation approach and original practice questions with explained answers.
General surgery on Step 2 CK is about recognizing who needs an operation, who needs resuscitation first, and which complication to expect. Trauma, the acute abdomen and postoperative care carry much of the weight.
Step 2 CK and Step 3 test clinical judgment: given a patient, what is the most likely diagnosis, the best next step in management, or the most important thing to prevent or monitor. The practice questions here are original and written to show the style of reasoning the exam rewards; they are not real exam items. Management guidance changes, so confirm current guidelines and the official USMLE content outline.
How General Surgery is tested
Questions describe an unstable or an acutely ill patient and ask for the next step: resuscitate, image, observe or operate. Others ask for the most likely cause of a postoperative problem or the work-up of a mass.
High-yield topics
- Trauma: the primary survey, hemorrhagic shock and the FAST exam
- Acute abdomen: appendicitis, cholecystitis, cholangitis, pancreatitis, bowel obstruction and perforation
- Hernias and abdominal wall problems
- Gastrointestinal bleeding and ischemia
- Breast, thyroid and other mass evaluation
- Vascular surgery: aortic aneurysm, limb ischemia and venous disease
- Perioperative care, postoperative fever and surgical complications
Preparation approach
- Learn the order of trauma care (airway, breathing, circulation, disability, exposure) and the signs that call for the operating room.
- For each acute abdominal condition, memorize the typical patient, the best first test and the definitive treatment.
- Review postoperative complications by day after surgery.
- Practice deciding between operating now and stabilizing first, because many questions turn on that choice.
Practice questions
Question 1
A man struck by a car has a blood pressure of 80/50 mm Hg, a heart rate of 130/min and a distended, tender abdomen. A FAST exam shows free fluid in the abdomen. What is the most appropriate next step?
- A. CT scan of the abdomen
- B. Observation in the intensive care unit
- C. Exploratory laparotomy
- D. Diagnostic laparoscopy only after stabilization with a CT
- E. Abdominal ultrasound repeated in 6 hours
Answer: C. A hemodynamically unstable trauma patient with a positive FAST needs emergent laparotomy, not imaging.
Question 2
A woman has a temperature of 38.5 C one day after abdominal surgery. She has decreased breath sounds at both lung bases. What is the most likely cause of the fever?
- A. Wound infection
- B. Atelectasis
- C. Deep venous thrombosis
- D. Urinary tract infection
- E. Anastomotic leak
Answer: B. Atelectasis is the most common cause of fever in the first 48 hours after surgery. Wound infections and leaks present later.
Question 3
A man has fever, jaundice, right upper quadrant pain, hypotension and confusion. Imaging shows a dilated common bile duct with a stone. After fluids and antibiotics, what is the most appropriate next step?
- A. Elective cholecystectomy in 6 weeks
- B. Urgent biliary decompression by ERCP
- C. Observation
- D. Oral ursodeoxycholic acid
- E. Repeat ultrasound in 24 hours
Answer: B. This is severe ascending cholangitis. In addition to antibiotics, urgent biliary drainage, usually by ERCP, is required.
