NUR 230 - Cardiovascular System Exam
Questions| Already Answered| GRADED
A+
To auscultate the right ventricle, you should have the patient do what? - ANSWER-Lean forward
To auscultate the left ventricle, you should have the client lay in what position? - ANSWER-Left lateral
In infants and children under 7 years old, the PMI is located in the ___ intercostal space - ANSWER-4th
Endocardium - ANSWER-Thin inner lining of the heart
Myocardium - ANSWER-Middle layer of muscle in the heart that has contracting, mechanical pump
Epicardium - ANSWER-Fibrous outer layer of the heart
Pericardium - ANSWER-Protective fibrous sac that surrounds the heart
If you have decreased pericardial fluid (<10mL) between pericardial layers, what would you hear upon
auscultation? - ANSWER-"Rub" and decreased heart sounds
(Left/Right) ventricle is 2-3x thicker, and stronger, than the other because it pumps blood into systemic
circulation - ANSWER-Left
AV valves - ANSWER-Prevent backward flow to atria when ventricles contract
Semilunar valves - ANSWER-Prevent backward flow to ventricles when ventricles contract
What are the two AV valves? - ANSWER-1. Tricuspid
, 2. Mitral (bicuspid)
What are the two semilunar valves? - ANSWER-1. Pulmonic
2. Aortic
S1 - ANSWER-Produced by closure of the mitral and tricuspid valves
S1 is best heard where? - ANSWER-Apex of heart
S2 - ANSWER-Produced by closure of the aortic and pulmonic valves
S2 is best heard where? - ANSWER-Base of the heart
S3 - ANSWER-This heart sound may be heard if ventricular wall compliance is decreased and structures
in ventricular wall vibrate; this can happen with heart failure or valvular regurgitation
S4 - ANSWER-This heart sound may be heard on atrial systole if resistance to ventricular filling is
present; usually this is abnormal and can be caused by left ventricular hypertrophy, CAD,
cardiomyopathy or aortic stenosis
Left coronary artery (LCA) has what two branches? - ANSWER-1. Left anterior descending artery (LAD)
2. Circumflex
This artery supplies the left atrium, left ventricle and part of the right ventricle - ANSWER-Left coronary
artery
This artery supplies blood to the right atrium, right ventricle, and part of the posterior wall of left
ventricle - ANSWER-Right coronary artery
After blood travels through myocardial capillaries, it returns via what? - ANSWER-Coronary veins to the
coronary sinus, which empties in the right atrium
