Alright I’m gonna shoot my shot and ask for some advice. As an LT, my rig has 3 medics. Well, one of my crew members for the life of him cannot grasp the concepts, differences or similarities between the following: pulmonary edema, emphysema, L/R heart failure. Correct me if I’m wrong, but this is not difficult and now I’m questioning how this individual passed to become a medic since the test clear as day has these questions on it. I have pulled the individual aside and worked with them on these concepts, ran scenarios, even made flash cards but nope nothing is clicking. We ran a call last night with a pt who has textbook emphysema and he had not even the slightest clue how to approach it. I brought it to the attention of some other elders in my department in hopes they could help but man I’m at a loss here. Any advice on how to approach this? Obviously this is stuff you NEED to know like the back of your hand.
