Amiodarone what is the effect - ANSWER - slowing the heart
Amiodarone, when is it used - ANSWER - V-fib, v tach, atrial tachyarrhythmia's
amiodarone what is the dosage given - ANSWER - 150 mg over 10 min if a pulse. no pulse give 300 mg rapidly and then 150 mg rapid for the next dose.
atropine, what does it do - ANSWER - speeds up the heart; increased conduction through the AV node
Atropine, when is it used - ANSWER - 1st drug given for bradycardia. can be given through the ETT
atropine, what is the dose given - ANSWER - dosing 0.5 mg IV every 5 min. max is 3mg
Warning: a dose <0.5 will actually cause the heart to slow.
dopamine, what is the effect - ANSWER - speeds the heart up and contractility increases. 1 / 3
pg. 2 it helps manage hypotension when there is no hypovolemia involved
dopamine when is it used - ANSWER - 2nd line drug for symptomatic bradycardia.
dopamine what is the dosage - ANSWER - 2-10 mcg for vasoconstriction 10-20 mcg for contractility effect for bradycardia give 2-10.we titrate until the we get the proper effect of the drug.
epinephrine, what does it do - ANSWER - increase heart rate and blood pressure
epinephrine when is it used - ANSWER - cardiac arrest, symptomatic bradycardia, severe hypotension, and anaphylaxis
epinephrine what is the dose - ANSWER - cardiac arrest 1 mg (10ml of 1:10,000 solution) premix every 3 minutes bradycardia 2-10 mcg/min titrate to effect for hypotension (remember to tank them up first) no dose on the study guide.
magnesium sulfate, when is it used - ANSWER - used for cardiac arrest only if torsade's de pointes or hypomagnesium is suspected
magnesium sulfate, what is the dose - ANSWER - 1-2 grams (2-4 ml of 50% solution) diluted in 10 ml of D5W IV (no time given)
vasopressin what is the effect - ANSWER - increased blood pressure
vasopressin what is the dose - ANSWER - 40 units IV for V fib and pulseless V tach. can be placed in the ETT. can take the place of epinephrine for either the 1st or 2nd dose or may not be used at all.

2) aspirate stomach contents q4h for residual 3) check the position of the feeding tube each shift 4) turn the patient frequently
Upon recognizing ventricular fibrillation in a safe environment, the nurse should then - ANSWER - 1)perform a precordial thump 2)establish unresponsiveness * 3)give amiodarone IV 4)check the ECG leads
The most important step in preventing central venous catheter related sepsis is: - ANSWER - 1)use of a transparent membrane dressing 2)changing the catheter weekly 3)using antibiotic ointment under the dressing 4)thorough handwashing *
