Just like the actual exam

Each question is written to resemble the format and topics on the exam, meaning you won’t see any negatively phrased questions, no “all of the following except,” no “A and B”…you know what we mean. Most importantly, all questions include selective distractors (incorrect answer choices), which will help you think critically.

  • Must address important content
  • Must be well structured


A 34-year-old man presents with a laceration on his right lower lip crossing the vermilion border. In order to decrease swelling during the procedure, you decide to perform a regional nerve block. Which of the following is the correct location for the injection in order to anesthetize this area?

A Junction of the gum and mucosa in between teeth 1 and 2
B Junction of the gum and mucosa in between teeth 25 and 26
C Junction of the gum and mucosa in between teeth 28 and 29
D Junction of the gum and mucosa in between teeth 7 and 8

Intussusception occurs when one segment of the intestine telescopes into another, usually the ileum into the colon. Constriction of the mesentery results in engorgement of the intussusceptum and bowel ischemia, causing the presenting symptoms. Intussusception occurs most commonly before the age of 2 years and is rare before 2 months. It often develops due to a lead point, which drags one portion of the bowel into another. In infants, it typically occurs due to lymphoid hyperplasia from a viral illness and in older children due to Meckel diverticulum, intestinal polyps, lymphoma, and immunoglobulin A vasculitis (formerly Henoch-Schӧnlein purpura). Intussusception is difficult to diagnose due to the variation in the common presentations of intermittent pain and lethargy. Classically, patients will present with a sudden onset of severe abdominal pain with the legs drawn to the chest and then will appear well until the next episode of pain. Another common presentation is an infant with unexplained lethargy. Although the classic teaching is to look for currant jelly stools, these are rarely present, with occult bleeding occurring in the majority of cases and gross bleeding present in half of the cases. Ultrasound is the initial image modality of choice. When there is a high suspicion of intussusception, patients should undergo an immediate air-contrast enema, which is both diagnostic and therapeutic.

CT of the abdomen and pelvis (A) is an imaging modality that can be helpful in diagnosing intussusception, but it is rarely needed and typically would not be the first diagnostic test in the evaluation. Upper GI series (C) can be helpful in diagnosing volvulus in infants and newborns. Midgut volvulus presents in infants with bilious vomiting and abdominal distension. An X-ray of the abdomen (D) is generally nondiagnostic for intussusception. In severe cases, when bowel perforation complicates intussusception, it may identify abdominal free air.


Written with a purpose

Understanding why an answer choice is incorrect is just as important as knowing why one is correct. That’s why every Rosh Review question includes detailed explanations for the correct and incorrect answer choices. These comprehensive summaries link the most important components of a topic—from risk factors to diagnostics and treatment—giving you the context to build relationships between them.

Q: Which nerve block would relieve severe dental pain of the right lower premolar?

Reveal Answer

A: Inferior alveolar.

I loved Rosh Review! It is laid out well, aesthetically pleasing to use, has a phone app so it’s convenient to use in little bits of downtime, and you can get CMEs. I went through all 1500ish of the questions and thought they were relevant to clinical practice in the ED. I really liked the pictures and graphs explaining questions and the “one step further” was a great pearl.
