Dysrhythmia Treatments Exam Questions With Correct
Answers.
Atropine Class - accurate answers-Anticholinergic
Atropine Ax - accurate answers-Blocks effects of PSNS, so SNS is unopposed
Atropine is used for... - accurate answers-Brady dysrhythmias & Heart Blocks
(not 3rd)
Atropine Desired Effects - accurate answers-Increased HR
Atropine S/E - accurate answers-Increased RR
Decreased motility
Urinary retention
Dry eyes, blurred vision
Dry exocrine glands (no sweat)
Epinephrine Class - accurate answers-Adrenergic agent
Sympathominmetic drug???
Epinephrine Ax - accurate answers-Activates fight or flight
Stim SNS
Epinephrine is used for... - accurate answers-Sx hypotension/syncope
associated with heart blocks and bradycardias
Cardiac arrest to stim SNS
Heart rate too slow
Epinephrine acts on... - accurate answers-Alpha 1/2
Beta 1/2
Epinephrine: Alpha 1/2 Fx - accurate answers-Alpha 1: vascular smooth
muscle
constrict to increase BP, bld flow to important areas
shrinks swollen mucous membranes
Alpha 2: in brain
constrict/same
, Epinephrine: Beta 1/2 Fx - accurate answers-Beta 1: heart and kidneys
increase HR and contractility
dilate coronary arteries so increased perfusion to kidneys and increased renin
production
Beta 2: lungs, skeletal muscle, visceral organs
bronchodilation
vasodilator skeletal muscles to increase O2 and energy
Digoxin (Cardiac Glycoside) Class - accurate answers-digitalis glycosides
Digoxin (Cardiac Glycoside) Ax - accurate answers-prolongs refractory period
by decreasing firing rate of SA and slowing conditioning through the AV node
Digoxin (Cardiac Glycoside) is used for... - accurate answers-ANY tachy
rhythms (Atrial or Vent or HB)
Digoxin (Cardiac Glycoside): What must you check before admin? - accurate
answers-Apical HR
Digoxin (Cardiac Glycoside): S/S of dig tox - accurate answers-N/V/D
Decreased HR
AV heart blocks
Confusion
Vision changes
Digoxin (Cardiac Glycoside) Desired Fx - accurate answers-Decreased HR
Increased force of contraction
Increased renal perfusion
Antidysrhythmic drugs Ax - accurate answers-Diminish/obliterate rhythm
disturbances by decreasing automaticity of cardiac tissue from the SA node,
altering rate of conduction of electrical impulses through the heart, and
altering the refractory period of cardiac muscles bw consecutive contractions
Antidysrhythmics Class 1a Def - accurate answers-Membrane stabilizing agent
Blocks Na channels (in atria, BoH, Purkinje) and affects Phase 0
(deoplarization)
