Medications Flashcards
What does digoxin do?
increases force of myocardial contractions, slows HR by decreasing conduction thru SA, AV nodes.
What does digoxin treat?
mild to moderate chronic atrial fibrillation
True of False Dig toxicity may result in hyperkalemia
TRUE
What does Atropine do?
decreases GI mobility, preop to inhibit salivation/secretions, increases HR
What is Atropine used to tx?
sinus bradycardia
What classification of meds may increase Atropine effects?
Anticholinergics
What are some side effects of Atropine?
dry mouth, nose, throat, decreased diaphoresis, constipation
What classification is Epinephrine?
Sympathomimetic(adrenergic agonist)
What does Epinephrine do?
increases contractility, HR, BP, CO-cardiac stimulation
What three rescue medications can be given ET Tube?
epinephrine, atropine, lidocaine
What medication is given first after shock?
Epinephrine
What are some side effects of epinephrine?
tachy, palpitations, anxiety, HA, eye irritation, dizziness, excessive doses can cause acute hypertension
What classification is Quinidine?
Antiarrhythmics
What are some side effects of Quinidine?
diarrhea, hypotension, N, V,
What does Amiodarone do?
suppresses arrhythmias, prolongs action potential, slows sinus rhythm
What is Amiodarone used for?
tx of ventricular fibrillation, hemodynamically unstable ventricular tachycardia.
What should you remember about Amiodarone?
long half life can be toxic to eyes and lungs.
What classification is Diltiazem?
Calcium Channel Blocker
What does Diltiazem do?
Decreases HR, contractility, slows SA and AV conduction, decreases PVR by vasodilation
What is Diltiazem used to tx?
Angina, Hypertension, temporary control of A. Fib/flutter, PSVT.
What classification is Adenosine?
Antiarrhythmic
What does Adenosine do?
depresses left ventricular function, restores normal sinus rhythm
What is adenosine used to treat?
PSVT
What classification is Verapamil?
Calcium Channel Blocker
What does Verapamil do?
decreases HR, myocardial contractility, slows SA, AV conduction, decreases PVR by vasodilation
What does Verapamil tx?
SVT, hypertension, A Fib./flutter
