NGR6002 Bate's Physical Exam
Final Study guide exam with
100% correct answers
Explain Systole - answer Ventricular Contraction; Aortic & Pulmonic
valves open, Mitral & Tricuspid valves close. Blood flows from the
ventricles through the aortic valve into the aorta to systemic
circulation.
Closure of the mitral valve during Systole is the first heart sound,
S1, representing the beginning of systole. S1 loudest at apex of
heart.
Explain Diastole - answer Ventricular relaxation; Blood flows from
atrias into ventricles. The mitral and tricuspid valves are open and
the aortic and pulmonic valves are closed. Aortic valve closure
creates the second heart sound, S2, marking the end of systole.
Loudest at base of heart.
S3 - answer Ventricular filling. Ken-Tuck-Y or "lub-dub-dub", usually
pathologic after 40 y/o: CHF or MI
S4 - answer Atrial contraction; Tenn-e-ssee or "dub-lub-dub", best
heard in mitral and tricuspid areas. usually pathologic after 40 y/o:
CHF, MI
Murmurs: where to hear them best - answer Longer duration than
heart sounds.
Mitral valve murmurs heard best at and around the apex. Best to
position patient onto the left side in the left lateral decubitus
position because it brings the left ventricle closer to the chest wall.
USE BELL
, Aortic murmurs: USE DIAPHRAGM, have patient sit and lean
forward, exhale completely and stop breathing in expiration. Press
stethoscope at left sternal border and at apex.
PMI: where do you find it - answer Point of maximal impulse; Have
patient exhale and hold breath; palpate 4-5th ICS, medial to the
MCL.
Five zones of cardiac auscultation - answer A: aortic
P: pulmonic
E: Erb's point
T: Tricuspid
M: Mitral
What does standing vs. squatting test for when auscultating cardiac
sounds? - answer Standing: venous return to the heart decreases,
as does peripheral vascular resistance. Arterial blood pressure,
stroke volume, and volume of blood in left ventricle all go down.
Standing: Increases mitral valve prolapse
Increases cardiomyopathy murmur
Decreases aortic stenosis murmur
