Sample Exam Questions: Pediatrics Written Exam
These multiple choice, “choose the one best answer” questions have been used on the Pediatrics Written Exam in the past, but have since been retired. The Written Exam contains some matching sets, and approximately one-quarter of the questions use visual exhibits. There are no true/false, K-type or negatively-worded “except” questions on the exam. These items are not meant to be a study guide, but rather samples of the type of questions seen on the certification and osteopathic continuous certification exams.
