CCRN exam Question And Answers 2025
S1 "lub" - correct answers ✅✅closure of AV (mitral and tricuspid)
valves
marks the end of diastole and the beginning of systole
SYSTOLE
S2 "dub" - correct answers ✅✅closure of the seminar (pulmonic
and aortic) valves
marks the end of systole and the beginning of diastole
DIASTOLE
systolic murmur
"lub.... shhhhb.....dub" - correct answers ✅✅semilunar valves are
OPEN during systole
- aortic stenosis
-pulmonic stenosis
AV valves are CLOSED during systole
- mitral insufficiency (will causes large, giant V-waves on the
pulmonary artery occlusion pressure tracing if the patient has a
pulmonary artery catheter)
- tricuspid insufficiency
diastolic murmur
,CCRN exam Question And Answers 2025
"lub...... dub.......shhhhb" - correct answers ✅✅semilunar valves
are CLOSED during diastole
- aortic insufficiency
- pulmonic insufficiency
AV valves are OPEN during diastole
- mitral stenosis (associate with atrial fibrillation due to atrial
enlargement that occurs over time)
- tricuspid stenosis
when are the AV valves OPEN and semilunar valves CLOSED -
correct answers ✅✅diastole
when are the AV valves CLOSED and the semilunar valves OPEN -
correct answers ✅✅systole
abnormal heart sounds in adults - correct answers ✅✅S3 (occurs
early in diastole, right after S2)
S4 (occurs right before S1)
pericardial friction rub (d/t pericarditis)
murmurs (valvular disease)
what causes S3 - correct answers ✅✅pulmonary hypertension
cor pulmonale (right sided heart failure)
mitral, aortic or tricuspid insufficiencies
, CCRN exam Question And Answers 2025
what causes S4 - correct answers ✅✅causes by atrial
contraction of blood into a noncompliant ventricle
associate with myocardial ischemia, infarction, hypertension,
ventricle hypertrophy and aortic stenosis
normal pule pressure - correct answers ✅✅40-60 mmHg
(systolic-diastolic=pulse pressure)
narrowing pulse pressure - correct answers ✅✅a decrease in
systolic blood pressure with little change or even an increase in
diastolic blood pressure
most often seen with hypovolemia or a severe drop in cardiac
output
systolic blood pressure - correct answers ✅✅is an indirect
measurement of cardiac output and stoke volume
widening pulse pressure - correct answers ✅✅a decrease in
diastolic pressure with little change to the systolic pressure
can indicate vasodilation or a drop is SVR
