answers 2025\2026 A+ Grade
S1
- correct answer 1st Try= TRICUSPID
LUB
R 2nd intercostal space
S2
- correct answer Aortic/Pulmonic
DUB
L 2nd intercostal space
Apical
- correct answer Apex of L Ventricle= Max impulse= oxygenated blood
L mid clavicular 5th intercostal space
bounding Apical = ?
- correct answer Pressure- BP and fluid (high salt, renal failure, urine retention)
Vascular resistance (too much cholesterol, arterial sclerosis)
,Which valves close tougher and what found do they make?
- correct answer Tricuspid R and Bicuspid (AV valve closes/ventricles filled=LUB)
Aortic L and Pulmonic L (emptying of blood through arteries= DUB)
inadaquate tissue perfusion
- correct answer diminished supply of nutrients necessary for metabolic function
buildup of metabolic waste
function of cardiovascular system
- correct answer 1. transporting nutrients and oxygen to body
2. removing wastes and carbon dioxide
3. maintaining adequate perfusion of organs and tissue
Heart facts
- correct answer R side sits more forward than L
>clenched fist
Female<male
Systolic VS Diastolic
- correct answer Systolic= ventricular CONTRACTION (S1-S2)
Diastolic= Ventricular RELAXATION (S2-S1)
S3 and S4, when and where
- correct answer S3
- children
- pregnant women 3rd trimester
- young adults
, S4
- children
- athletes
- healthy elderly
Ventricular gallop and atrial gallop
- correct answer Ventricular= S3- vibrations caused by the AV valves being open and blood flowing into
the ventricles
Atrial= S4- atrial contraction/ejection of blood into ventricles
S3/ S4 indication
- correct answer may be associated with Myocardial infarction or heart failure
S1 best auscultation site
- correct answer apex
S2 best auscultation site
- correct answer 2nd intercostal
When is a Split S1 abnormal
- correct answer if you can hear it over the apex
heard toward the end of inspiration
aortic valve closes > pulmonic valve= T-DUB
S3 and S4 best ausculation
- correct answer apex
Low pitch
Opening snap
- correct answer Mitral stenosis
Left 3rd to 4th ICS
