|
1)decrease BP, HR, RR
2)(+) rales 3)AV blockade 4)increase glucose (inhibits release of insulin from pancreas) 5)increase AG (hypotension) 6)decrease BS |

|
How do you ASSESS a patient's airway and breathing with a pCO2 of 50 and ABG of 7.29?
|
respiratory acidosis (depressed respiration w/ CO2 retention)
|

|
How do you assess between a verapamil and nifedipine overdose?
|
VERAPAMIL
1)negative inotrope = +++ 2)vasodilation = +/- 3)AVN conduction = --- NIFEDIPINE 1)negative inotrope = +/- 2)vasodilation = +++ 3)AVN conduction = +++ (reflex tachycardia) |

2)Glucagon IV 10mg 3)Atropine 0.5-1mg IVP |
|
|
What is the MOA of glucagon?
|
bypassses the beta-receptor and increases cAMP -> increases contractility and HR
