Adenosine what if the patient does not respond to the 6mg - ANSWER - if no response in 1-2 min give 12 mg and flush. may repeat.
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

aspiration is to: - ANSWER - 1) keep the head of the bed elevated *
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 *
