NUR 550 CORRECT STUDY QUESTIONS AND
ANSWERS SET A+
✔✔What murmur is associated with mitral valve prolapse? - ✔✔Mid-systolic click with
late systolic murmur.
✔✔Where is mitral valve prolapse best heard? - ✔✔Apex.
✔✔Classic auscultation finding of MVP? - ✔✔Mid-systolic click.
✔✔MVP is often associated with what type of patient? - ✔✔Young, thin female patient,
though it can occur in many groups.
✔✔What maneuver makes MVP click occur earlier? - ✔✔Standing or Valsalva.
✔✔What maneuver delays MVP click? - ✔✔Squatting.
✔✔What murmur is associated with tricuspid regurgitation? - ✔✔Holosystolic murmur at
the left lower sternal border.
✔✔What increases the murmur of tricuspid regurgitation? - ✔✔Inspiration.
✔✔Why does inspiration increase right-sided murmurs? - ✔✔Inspiration increases
venous return to the right heart.
✔✔Tricuspid regurgitation is associated with what systemic findings? - ✔✔JVD,
hepatomegaly, ascites, peripheral edema.
✔✔Tricuspid regurgitation can contribute to what type of heart failure? - ✔✔Right-sided
heart failure.
, ✔✔What is an innocent murmur? - ✔✔A benign murmur without structural heart
disease.
✔✔Typical quality of an innocent murmur? - ✔✔Soft, systolic, short, no radiation, and
no symptoms.
✔✔What findings make a murmur concerning? - ✔✔Diastolic murmur, loud murmur,
radiation, symptoms, cyanosis, syncope, abnormal pulses, or signs of HF.
✔✔Why is echocardiography preferred for murmur evaluation? - ✔✔It visualizes valve
structure, blood flow, chamber size, and cardiac function.
✔✔What is a ventricular septal defect? - ✔✔Opening between the ventricles causing
left-to-right shunting.
✔✔Classic murmur of VSD? - ✔✔Harsh holosystolic murmur at the left lower sternal
border.
✔✔What is an atrial septal defect? - ✔✔Opening between the atria causing left-to-right
shunting.
✔✔Classic heart sound finding in ASD? - ✔✔Fixed split S2.
✔✔Stable angina is caused by what? - ✔✔Temporary myocardial ischemia from fixed
coronary artery disease.
✔✔Stable angina pattern? - ✔✔Predictable chest discomfort with exertion or stress,
relieved by rest or nitroglycerin.
✔✔Unstable angina pattern? - ✔✔New, worsening, prolonged, or rest chest pain.
✔✔Why is unstable angina dangerous? - ✔✔It may progress to myocardial infarction.
✔✔Does unstable angina cause troponin elevation? - ✔✔No, troponins are typically
negative because there is no myocardial necrosis.
✔✔What is myocardial infarction? - ✔✔Myocardial ischemia with cell death/necrosis.
✔✔Classic MI symptoms? - ✔✔Chest pressure, radiation to arm/jaw/neck/back,
diaphoresis, nausea/vomiting, dyspnea.
✔✔Women, older adults, and diabetics may have what kind of MI symptoms? -
✔✔Atypical symptoms such as fatigue, dyspnea, weakness, nausea, or epigastric
discomfort.
