PEM practice questions - frequently asked questions

Plain answers about how PEM Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real PEM exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The PEM exam spans 28 domains: Trauma (12% of the exam); Resuscitation (10% of the exam); Infectious Diseases (8% of the exam); Procedures (5% of the exam); Special Populations (3% of the exam); Neonatal Conditions (2% of the exam); Toxicology (4% of the exam); Child Abuse and Maltreatment (4% of the exam); Behavioral Health Conditions and Psychosocial Issues (3% of the exam); Cardiovascular (3% of the exam); Pulmonary (8% of the exam); Hematologic and Oncologic (4% of the exam); Gastrointestinal (3% of the exam); Neurologic/Neurosurgical (3% of the exam); Environmental Emergencies (3% of the exam); Allergic, Rheumatologic, and Immunologic (2% of the exam); Eyes, Ears, Nose, Oral, Neck (2% of the exam); Renal and Electrolyte (2% of the exam); Dermatologic (2% of the exam); Endocrine (2% of the exam); Obstetrics/Gynecologic (2% of the exam); Urologic (1% of the exam); Metabolic/Genetic Emergencies (1% of the exam); Musculoskeletal/Orthopedic (1% of the exam); Mass Casualty and Disaster Preparedness (2% of the exam); Emergency Medical Services and Transport (2% of the exam); Emergency Department Operations and Patient Rights (2% of the exam); Core Knowledge in Scholarly Activities (4% of the exam).
