At BoardVitals, we pride ourselves on bringing you the most up-to-date questions to ensure you’re prepared to pass the boards. When exams like the USMLE cover such a wide array of topics, it’s easy to get stuck on a specialty section that isn’t your strong suit. We’ve partnered with Dr. Roger Seheult, MD at MedCram to make videos reviewing and explaining those particularly complicated questions.

Check out one of our collaborative videos featuring a practice question from our USMLE Step 1 question bank. Try answering the question before you watch the explanation video.

Question: A 35-year-old female was being evaluated for diabetes. She visited a diagnostic center to get a glucose tolerance test done. The attending staff at the center accidentally administered 10 times the dose of oral glucose which was supposed to be given. After some time she showed neurologic disturbances and they sent her to the ED by ambulance. At the ED she was found to have lactic acidosis. The physicians strongly suspect an inborn defect of carbohydrate metabolism. Which of the following enzymes is probably deficient in the patient which led to lactic acidosis?

A. Glycogen Synthase
B. Liver phosphorylase
C. Pyruvate dehydrogenase
D. Phosphofructokinase 1
E. Muscle phosphorylasetokin
