What is the drug of choice for symptomatic bradycardia? - answers - -atropine
What medication is given for cardiac arrest? What medication is given for prinzmetal's
angina? - answers - -arrest: epi
-prinzmetals: ccb
What is the anatomical location of the pmi? - answers - -5th ics/ mcl
Valvular heart disease result in murmurs. Where is the murmur associated with mitral
regurgitation heard? - answers - -the apex
What does sinus tachycardia result in? - answers - -decreased diastolic filling
-decreased co
What percentage does atrial kick (or contractions) contribute to co? What dysrhythmia
does the loss of this kick occur with? - answers - -accounts for 25% of co -> loss with a
fib
A big concern with a fib is pulse deficit. What does this mean? - answers - -widened
pulse value between the apical pulse and the radial pulse
A fib presents as quivering on the strip with no real contractions. What does this
increase the risk of? How should patients be treated for this? - answers - -increases
the risk of clots -> treated with anticoagulant
What drug is given for rvr associated with uncontrolled a fib? - answers - -diltiazem
(ccbs)
What is the first-line medication for htn? - answers - -ace inhibitor - typically lisinopril
An increase in preload will result in increased co as a result of what? - answers - -frank
starling's law -> stretching of wall during preload increase the force of contraction
What kind of inotropic effect does metoprolol have? What does this mean? - answers -
-negative inotropic effect -> decreases myocardial workload
Does acidosis or alkalosis decrease myocardial contractility? - answers - -acidosis

Vasodilation is a result of
A. Decreased o2
B. Increased co2
C. Decreased co2
, D. Acidosis - answers - -answer: a, b, d

Untreated strep throat is a risk factor for rf and rhd. What should a person do if they
present with s/s of strep? - answers - -go to doctor's office to get culture -> if positive
then get antibiotics
What is a hallmark sign of aortic regurgitation? - answers - -widened pulse pressure
(aka water-hammer pulse)
A defibrillator must be in synchronous mode in order to avoid hitting the t wave. What
should it be aiming for?
A. P wave
B qrs complex
C qt interval
D r wave - answers - -answer: r wve
