I am a new nurse as well! I would think ABC, airway breathing circulation. So, breathing is high, how is the O2 sat, what has the patient been running for BP, maybe sepsis or dehydrated because of low BP and high HR. What are current labs and urine output. Maybe they need fluids, I would let doctor know of changes. I had a situation where this happened and I am currently a nurse aide, and the patient became a rapid response! However his BP was in the 80's, from previous 120's and he had fluctuating temp and chance of LOC...
