wall in 10% of pop
Ramus artery - correct answer20% of the population has it. Tertiary left main; runs along the LV,
between the LAD & circumflex
SVR - correct answerSystemic Vascular Resistance- the resistance the LV has to overcome to
eject. (Afterload)
PVR - correct answerPeripheral vascular resistance: the resistance the RV has to overcome to
eject
S1 - correct answerClosure of the MV and TV; Systole; 1/3 of the cardiac cycle "Lub"
S2 - correct answerClosure of the pulmonic and aortic valve; Diastole; 2/3 of the cardiac cycle;
DUB
S3 - correct answerAuscultated in fluid overload; when preload is elevated; KENTUCKY
S3 is normal in which popuation(s)? - correct answerNormal in kids, high CO like pregnancy
(3rd trimester)
S4 - correct answerAtrial gallop (pre-systolic); sound caused by vibration of atria ejecting into
non compliant ventricle; Tennessee

Indications for ACE Inhibitors - correct answerCHF/Systolic Failure, AMI (EF <40%), Anterior
wall MI, HTN, Diabetic Renal Nephropathy
-prils Angiotensin Converting Enzyme
Effects of ACE Inhibitors - correct answerVasodilation, decrease preload & afterload, prevention
of myocardial remodeling, reduce progress of diabetic nephropathy
What do you want to monitor for in ACE inhibitor administration? - correct answerHypotension,
hyperk, cough/angioedema, renal function
Cardioselective B-Blockers - correct answerBlocks B1--> Bisoprolol, metoprolol SR, Atenolol,
Esmolol, Acebutolol, Nebivolol
Alpha & Beta Blocking Medications - correct answerLabetalol, Carvedilol (Coreg)
Non-selective Beta Blocking Medications - correct answerBlocks B1 + B2; Propanolol, Timolol,
Nadolol, Sotalol
Indications for Beta Blockers - correct answerHTN, Secondary prevention of MI (metoprolol +
carvedilol), Cardiac arrhythmias, angina, Afib, CHF/Systolic HF
Effects of B Blockers - correct answerDecreases HR/BP, negative inotrope by decreasing
myocardial workload, decreases preload, blocks stress catecholamines (epi + NE), decreases
morbidity/mortality, decreases arrhythmias
What should you monitor for in B blocker administration? - correct answerLow HR, Low BP,
AV Blocks, HF, signs of shock, bronchospasm; cocaine use
B blocker reversal agent - correct answerGlucagon
How do Angiotensin Receptor Blockers work? - correct answerThey block AT1 receptors that
hormones act on which are found in the heart, blood vessels, and kidneys. Block Angiotensin 2
to help lower BP
