NSG 3160 EXAM 3 NEWEST EXAM 2025
QUESTIONS AND ANSWERS | A+ GRADE
VERIFIED ANSWERS
Right side of the heart pumps to... Correct Answer Lungs
Left side of heart pumps... Correct Answer simutaneously
to body
Septum Correct Answer wall that separates two pumps
atrioventricular valves Correct Answer separate atria and
ventricles
heard at apex, located at bottom of heart: 5th rib
intercostal space
Apical pulse is also called Correct Answer Mitral
area/PM/Apex
Right AV valve = Correct Answer tricuspid valve, 5th
intercostal space at left sternal border
Left AV valve = Correct Answer Mitral valve, 5th
intercostal space at left midclavicular line
Semilunar (SL) valves Correct Answer between ventricles
and arteries
3 cusps that look like half moons
heard at BASE, located at TOP of heart
,pulmonic valve Correct Answer located on right side of
heart, 2nd L intercostal space
aortic valve Correct Answer located on left side of heart,
2nd R intercostal space
Diastole phase Correct Answer ventricles relax, heart fills
with blood
2/3 of cycle
AV valves (tricuspid and mitral) are OPEN
pressure in atria is higher than in ventricles.
1st filling phase is called early or protodiastolic filling.
2nd filling is called presystole or atrial systole
Systole phase Correct Answer blood pumped from
ventricles and fills pulmonary and systemic arteries
1/3 of cardiac cycle
ventricular pressure is now HIGHER than that of atria,
causing atria to close. After blood ejection, pressure falls
in ventricles. When pressure falls below pressure in aorta,
some blood flows backward towards ventricle, causing
aortic valve to shut.
S1 or Lub Correct Answer closer of AV valve
S2 or Dub Correct Answer closure of semilunar valve
S3 heart sound Correct Answer ↑ventricular filling
pressure (e.g., mitral regurgitation, HF), common in dilated
ventricles. VIBRATIONS heard over chest. A gallop.
,Occurs immediately after S2 (LUB DUB DUB). May be
early sign of heart failure.
S4 heart sound Correct Answer occurs at end of Diastole,
at presystole. HEARD BEST AT APEX w/ pt turned to
LEFT LATERAL so heart is closer to chest wall.
VIBRATION is very soft and low pitch. Occurs jsut before
S1 (DUB LUB DUB)
murmur Correct Answer abnormal swishing sound caused
by improper closure of the heart valves. turbulent blood
flow.
Automaticity Correct Answer contracts by itself,
independent of any signals or stimulation from body.
SA node Correct Answer "pacemaker" of heart
P wave Correct Answer atrial depolarization
PR interval Correct Answer beginning of P wave to
beginning of QRS complex
QRS complex Correct Answer depolarization of the
ventricles
T wave Correct Answer repolarization of ventricles
Cardiac Output (CO) Correct Answer Amount of blood
pumped in 1 minute (4-6 L)
CO=SV x R
, carotid artery Correct Answer located in groove b/w
trachea and sternomastoid muscle. palpate only 1 at a
time.
jugular vein Correct Answer Vein that carries blood from
the R atrium into the superior vena cava
Risk factor for CVD Correct Answer elevated cholesterol
High BP
Known diabetes or blood sugar levels above 11 mg/dL
Obesity
Cig smoking
Low physical activity
gender
length of hormone replacement therapy
Aging adult heart Correct Answer hemodynamic changes
(increase in systolic BP caused by THICKENING &
STIFFENING of large arteries. Diastolic BP may decrease
after 5th decade of life. Heart size and heart rate do not
change. INCREASE in AP diameter (difficulty palpating
apical pulse). SYSTOLIC MURMUR. DYSRHTHMIAS
(INCREASE in presence of supra-ventricular and
ventricular dysrhythmias.
Bruit Correct Answer blowing, swooshing sound indicating
BLOOD FLOW TURBULENCE heard through a
stethoscope when an artery is partially occluded
