CCT Exam - Cardiac Medications With Complete Solutions And 100% Correct Verified Answers| Well Graded A+ Type II antiarrhythmics - CORRECT ANSWERS-Beta-blockers: reduce rate and conduction Type III antiarrhythmics - CORRECT ANSWERS-potassium channel blockers: prolong the refractory period **may produce PR arrhythmias like torsade’s de pointes i.e. amiodarone, sotalol Type IV antiarrhythmics - CORRECT ANSWERS-calcium channel blockers: slow conduction velocity, (prolongs QRS) and lengthens the refractory period (prolongs QT interval) i.e. verapamil, diltiazem Nitrates - CORRECT ANSWERS-decrease the heart's oxygen demand (reduce afterload) i.e. nitroglycerin, isosorbide mononitrate, isosorbide dinitrate Epinephrine - CORRECT ANSWERS-causes vasoconstriction, increased HR and contractility Atropine - CORRECT ANSWERS-antimuscarinic agent: blocks the effect of acetylcholine at the sinus and AV nodes Lack of oxygen to the brain will cause... - CORRECT ANSWERS-the brain to become acidic and will cause permanent damage or death within 5-6 minutes Isuprel - CORRECT ANSWERS-adrenergic agonist: stimulates beta receptors causing increased HR and force of contraction as well as slight vasodilation Alpha blockers - CORRECT ANSWERS-block alpha-1 receptors to inhibit norepinephrine at the receptor site i.e. doxazosin, prazosin, terazosin Verapamil - CORRECT ANSWERS-antianginal, antihypertensive, antiarrhythmic -- smooth muscle relaxation, widening of blood vessels to increase oxygen delivery to heart. Decreases conduction through the AV node.

CCT Exam - Cardiac Medications With Complete
Solutions And 100% Correct Verified Answers| Well
Graded A+

Type II antiarrhythmics - CORRECT ANSWERS-Beta-blockers: reduce rate and
conduction

Type III antiarrhythmics - CORRECT ANSWERS-potassium channel blockers: prolong
the refractory period

**may produce PR arrhythmias like torsade’s de pointes

i.e. amiodarone, sotalol

Type IV antiarrhythmics - CORRECT ANSWERS-calcium channel blockers: slow
conduction velocity, (prolongs QRS) and lengthens the refractory period (prolongs QT
interval)

i.e. verapamil, diltiazem

Nitrates - CORRECT ANSWERS-decrease the heart's oxygen demand (reduce
afterload) i.e. nitroglycerin, isosorbide mononitrate, isosorbide dinitrate

Epinephrine - CORRECT ANSWERS-causes vasoconstriction, increased HR and
contractility

Atropine - CORRECT ANSWERS-antimuscarinic agent: blocks the effect of
acetylcholine at the sinus and AV nodes

Lack of oxygen to the brain will cause... - CORRECT ANSWERS-the brain to become
acidic and will cause permanent damage or death within 5-6 minutes

Isuprel - CORRECT ANSWERS-adrenergic agonist: stimulates beta receptors causing
increased HR and force of contraction as well as slight vasodilation

Alpha blockers - CORRECT ANSWERS-block alpha-1 receptors to inhibit
norepinephrine at the receptor site

i.e. doxazosin, prazosin, terazosin
Verapamil - CORRECT ANSWERS-antianginal, antihypertensive, antiarrhythmic --
smooth muscle relaxation, widening of blood vessels to increase oxygen delivery to
heart. Decreases conduction through the AV node.
