Didactic Year Exams

Tame the whirlwind of PA-1 year with 1,800 didactic-level questions created to help you excel in Subject Exams and the End of Didactic Year Exam.


Just like the actual exam

Tame the whirlwind of PA-1 year. Authored & peer-reviewed by PA-Cs who excelled in PA school and on the PANCE. Each question is written to help you build a strong foundation of knowledge, digest the information you’re learning, and ace your subject exams.

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 10-month-old boy presents to the emergency department with his mother due to complaints of vomiting, intermittent abdominal pain, and lethargy. On physical exam, a sausage-shaped mass is palpated in the right upper quadrant of the abdomen, and a sensation of emptiness is found in the right lower quadrant. Which of the following diagnostic testing methods is recommended to confirm the diagnosis of intussusception?
A Computed tomography scan
B Magnetic resonance imaging
C Plain radiography
D Ultrasound
Correct Answer Distractors
Intussusception is the most common abdominal emergency seen in young children. It occurs when a part of the intestine invaginates or telescopes into itself, causing a bowel obstruction. Intussusception generally occurs between 6 and 36 months of age, with boys affected more frequently than girls. Most cases have an idiopathic etiology. Patients generally present with complaints of vomiting, intermittent or colicky abdominal pain, lethargy, and rectal bleeding. Vomiting is initially nonbilious, but when the obstruction occurs, it becomes bilious. Parents may report the child draws their legs up toward the abdomen or kicks their legs in the air due to the pain. Lethargy is commonly seen and may be intermittent in nature. Stools can be a mixture of mucus, blood, and sloughed mucosa, with an appearance described as currant jelly. Diarrhea may also occur in the early stages of the condition. Patients may often not have the classic signs of intussusception, which can delay the diagnosis and cause the condition to become more life-threatening. Ultrasound has a high sensitivity and specificity in the diagnosis of intussusception and is the method of choice at many hospitals. The classic finding on ultrasound is the target sign, which occurs when layers of intestine are within the intestine. Treatment options include nonoperative reduction or surgical intervention. Younger patients with an idiopathic cause to the intussusception are generally responsive to nonoperative intervention. Nonoperative reduction is with a therapeutic enema under fluoroscopic or ultrasound guidance. The two types of therapeutic enemas used are hydrostatic with either water-soluble or barium contrast or pneumatic air insufflation. Surgery is indicated when the patient is unstable, nonoperative reduction is unsuccessful, or there is peritonitis or intestinal perforation.
