HFHS Critical Care Exam Questions AND Correct Answers
5 points/location of Cardiac Assessment Landmarks -
✔✔Aortic- R sternal border, 2nd ICS
Pulmonic- L sternal border, 2nd ICS
Erbs point- L sternal border, 3rd ICS
Tricuspid- L sternal border, 4th ICS
Mitral- L MCL, 5th ICS
s1- closure of mitral-tricuspid
s2- closure of aortic-pulmonic
accelerated idioventricular rhythm - ✔✔Rate: 50 - 100
usually (usually slow)
P wave: Obscured by ventricular waves (occur during
ventricular contraction) - SA node slower than faster
ventricular pacing than should be
QRS: Wide QRS
Conduction: Ventricular only
Rhythm: Regular
-No PR interval
,- benign rhythm that is sometimes seen during acute MI
or early after reperfusion. - Rarely sustained, does not
progress to vfib, rarely requires treatment
Acidosis on EKG - ✔✔Low amplitude of QRS
ACLS bradycardia - ✔✔1mg atropine every 3-5 mins up
to 3mg
-If not effective consider transcutaneous pacing or
dopamine/epi infusion
ACLS tx for stable tachycardia - ✔✔Vasovagal
maneuvers; adenosine 6mg then 12mg then progress to
procainamide/amio bolus and inufsion
ACLS tx for unstable tachycardia - ✔✔synchronized
cardioversion
Adenosine - ✔✔-Antiarrhythmic
, -Drug of choice in treating SVT
-Very short acting (~ 15 sec). Effects blunted by
theophylline and caffeine (both are adenosine receptor
antagonists).
-Slows conduction of AV node, resetting electrical
conduction upset during SVT
Afterload - ✔✔the amount of resistance to ejection of
blood from the ventricle
-affected by SVR, intrathoracic pressure
-affects stroke volume/CO
Amiodarone - ✔✔Antiarrhythmic
Slow conduction rate/prolongs refractory period of
SA/AV node
-Decreases HR, afterload
--May prolong QT interval
Assist control vent mode - ✔✔"resting mode"
Fully supports pt w/ every breath
