As we all know, you have to know the information, but I feel like with orals, they want to make sure you're thinking and not just a robot.
For example, 70 yo patient getting an AVR and upon induction his BP drops to 70/50 and the HR goes to 110, what do you do next doctor?
A failing answer is, give some neo to get the BP up. (Even if you explain why you're giving Neo over something else and why, it's still not a "consultant" answer.
This is just an brief example but they want to make sure you're not a robot.
A better answer, first I'd ensure adequate oxygenation and ventilation, then I'd check his rhythm, then I'd ...etc etc. etc...... That's more like a consultant answer. You're going through the entire process and that is basically what Ho teaches. To get that most out of Ho, you should already have the background knowledge and they just teach how to answer questions. Yes, there will be questions that you have no clue how to answer. "I'm not sure" and move on, to goal is to get more questions to show what you DO know.
You really have to explain your thinking in a organized and reasonable way. You can't "just intubate" or "just give some neo". If they want the drug they'll say, "What drug doctor?" and then just tell them the drug and move on...don't explain how the drug works because that's not what they asked you.
Also, be careful quoting studies because you can dig a hole if you don't know the details. We all know PA catheters have shown no benefit in non-cardiac surgery. If they ask, "do you want a PA?" I would simply say NO and explain why other monitors are adequate.
The orals are tricky but can be done with, as everyone else is saying.......
