All right, so let's go back to the questions from our previous session before we continue with our case. I gave you this first question about optimal location for needle decompression, and historically choice B was the only correct answer on the screen. However, some recent cadaver studies and observational studies show mixed results, and that perhaps a lateral approach at the fourth and fifth intercostal space anterior axillary line may be a better option, or at least equivalent. So I put both of these as possible correct answers. The answer to our question about traumatic hemothorax is C, 1,500 mLs. However, I want the biggest learning point here from this question to be that the decision to perform operative exploration should really weigh heavily on the patient's physiology, hemodynamics, and transfusion requirements. So always keep those in mind. And lastly, respiratory rate is not part of the ABC score, as you heard from Dr. Valenzuela. The four components are penetrating mechanism, positive FAST exam, systolic less than 90, and heart rate greater than 120. So now back to our case. On arrival to the ICU, the patient is still hypotensive, and the team is working hard to round out his resuscitation and correct his coagulopathy. First question for this section, which of the following is not a component of the lethal diamond of trauma? Dr. Valenzuela talked about the lethal triad of trauma. Can we go back one slide, please? Thank you. Let's make sure that the question is up. You may have to refresh it. And when you do, it does show up. So just refresh your page if it's showing an old question. I'll give you a couple more seconds. All right. Fortunately, the hospital does have access to thrombolystography, a technology that allows us to evaluate the blood's ability to clot. They get the following results. So next question, based on this tag curve, which of the following would most benefit the patient? Cryoprecipitate, FFP, tranexamic acid, or platelets? Let's go back one slide, please. I'll give you a few seconds to answer this one. All right. Now, while the patient continues to be transfused, the team thinks about important sources of bleeding. Hemorrhage into which of the following does not have the potential to lead to hemorrhagic shock? Can we go back one, please? All right. Now, while the patient continues to be transfused, the team thinks about important sources of bleeding. Hemorrhage into which of the following does not have the potential to lead to hemorrhagic shock? Can we go back one, please? Oh, we're looking pretty good on this one. All right.
