Critical Thinking

One of my classes is online and we've been dealing with "Critical Thinking". We were presented with a scenario in which Patient A has chest pains, Patient B needs a bath, Patient C needs to be transported to the another department for testing and a doctor has requested the most recent vitals on Patient D. In this scenario you are a LVN/LPN over another LVN/LPN and a CNA.

My solution was to head over to Patient A's room as I direct the other LVN to wash Patient B and I tell the CNA to trasport Patient C for testing. I figure when I'm done I'll get the vitals for Patient D or I'll direct the other LVN or CNA to do it if they find me still in Patient A's room dealing with his chest pain.

My other class mates are telling me that I should rushed over to Patient's A's room (ignoring my LVN/CNA and other patients) and deal with his chest pain until I'm certain that he/she is not having a heart attack.

Why can't I tell my other team memebers what to do as I'm heading towards a possible emergency? It seems to me that I'm wasting resources if I rush off to Patient A's room and leave my team members standing around.
