I think interventions a and b are not important for the moment. My struggle is to choose between c and d as my first intervention if I ever find myself in the situation to assess an inebriated patient. I know that nail gun incidents can lead to tetanus infections and I would want to know whether my patient has been immunized and how long it has been since he has been immunized (to determine if he is still protected by the vaccine or not). But then, wouldn't I want to know his current blood alcohol level first to help me make a decision as to my next interventions? I know I cannot give the tetanus shot to a person who has been consuming alcohol, for that might lead to a dangerous systemic reaction. So, I guess, I'm a bit confused at to which of c and d I should do first.
P.S. Also, I have not received any private message. I would prefer that we discuss this problem here on the forum so I can understand better how the prioritization has been done.
