SDN Members don't see this ad. (About Ads) Only done 100 questions and 2 questons I have serious issues with. 1st is a bleeding kid with elevated PTT and normal PT. Answer choices include Hemophilia A and VWD. Answer was Hemophilia A because "WVD is primarly a platelet disorder." Bullshyt. According to Goljan and Harrison's VWD also has an elevated PTT. The question should have included a bleeding time. 2nd is a kid with Hirshprung's disease. Stool is seen and evacuated during a digital rectal exam. In Hirshprung's, the rectal vault is supposed to be EMPTY with proximal dilatation.
