In the end the great truth will have been learned, that the quest is greater than what is sought, the effort finer than the prize, or rather that the effort is the prize, the victory cheap and hollow were it not for the rigor of the game.  -Justice Benjamin Cardozo

Welcome back to episode 8! With Thanksgiving behind us, let’s keep up the momentum, as the In-Training Exam is right around the corner. Here is a sneak peek into the category breakdown established by ABEM for the ITE.

Roshcast episodes are 10–15 minutes long so you can focus on a few topics at a time without feeling overwhelmed. The short duration of each episode also allows you to go back and review episodes you may have missed or want to reinforce.

We begin each episode with a quick Rapid Review of the previous week’s highlights. 

* Rh immunoglobulin administration can be delayed up to 72 hours. The correct dose is 50 mcg for those less than 12 weeks gestation and 300 mcg for those 12 weeks and over.* Haloperidol and other typical antipsychotics can cause a dystonic reaction. The treatment is either benztropine or diphenhydramine. 50% of reactions occurring within 48 hours of administration and 90% occur within 5 days.* The target pH for eye irrigation should be between 7.0–7.2, but do not delay irrigation to confirm a staring pH.* Sulfonylureas commonly cause recurrent hypoglycemia as they stimulate the islet beta cells to secrete more insulin, increase the sensitivity of peripheral tissues to insulin, and have a prolonged half-life.
