BKAT 9r Exam 2023/2024
Adenosine, when is it used? - Answer- Paroxysmal supraventricular tachycardia
Adenosine, what is the effect - Answer-
... [Show More] slows the heart
adenosine what is the dosage given - Answer- 6mg IV push rapidly followed by 20mls of NS.
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.
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.
Mr Adams, a 68 yo patient, complains of feeling "a little funny in his chest". His EKG shows atrial fibrillation/flutter. Which of the following medications could be used to treat his cardiac rhythm? - Answer- 1)Levophed
2)nifedipine
3)Cardizem *
4)adenosine
A patient becomes apneic and pulseless. The monitor shows asystole. The drug that would most likely be used initially is - Answer- 1)amiodarone
2)atropine
3)epinephrine *
4)lidocaine
When feeding a patient using continuous tube feedings, the most important intervention in preventing 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 [Show Less]
