Heart valves on the right side of the heart - correct answer Tricuspid Valve, Pulmonary Valve
How does blood flow through the tricuspid valve? -
... [Show More] correct answer Blood flows from the right atrium, to the right ventricle
How does blood flow through the pulmonary valve? - correct answer Blood flows from the right ventricle, to the pulmonary arteries
Heart valves on the left side of the heart - correct answer Aortic valve, mitral valve
How does blood flow through the mitral valve? - correct answer Blood flows from the left atrium, to the left ventricle
How does blood flow through the aortic valve? - correct answer Blood flows from the left ventricle, into the aortic arch
What does S1 sounds like? What is happening in heart? - correct answer S1 is the first heart sound heard (the "lub" in "lub-dub"). The sound is caused by the closure of the mitral and triscupid valves at the start of systole
What does S2 sound like? What is happening in the heart? - correct answer S2 is the second heart sound heard (the "dub" in "lub-dub"). The sound is caused by the closure of the aortic and pulmonic valves - representing the end of systole
What does S3 sound like? What is happening in the heart? - correct answer S3 is an extra heart sound, called a gallop. It happens right after S2, and signifies atrial or mitral regurgitation, left ventricular heart failure, or volume overload.
What does S4 sound like? What is happening in the heart? - correct answer S4 is an extra heart sound, called a gallop. It happens before S1, and signifies HTN, acute MI, aortic stenosis, pulmonary stenosis, pulmonary HTN
What are the types of coronary ischemia? - correct answer Stable angina, unstable angina, and AMI
What interventions are needed for coronary ischemia? - correct answer Stress echo, nuclear perfusion imaging or cardiac catheterization
What is stable angina? - correct answer Exercise-induced chest pain relieved by rest or nitroglycerin
What is unstable angina? - correct answer Angina that is either new in onset or differs from a patient's typical stable angina pattern. Pain at rest does not respond to nitroglycerin. Precursor to MI.
What causes unstable angina? - correct answer Rupture of plaque with w/thrombus and incomplete occlusion of coronary artery
What EKG changes are seen with unstable angina? - correct answer T-wave inversion, or ST depression, occasionally ST elevation.
What are AHA core measures for chest pain? - correct answer EKG within 10 minutes, thrombolytic within 30 minutes, cath-lab within 90 minutes
Classic signs/symptoms of MI - correct answer Chest pressure/pain, radiates to jaw/left arm, not relieved by sublingual nitro, SOB, diaphoretic, pallor, anxiety, nausea/vomiting
Atypical MI symptoms - correct answer Fatigue, palpitations, dizziness, acute CHF, pulmonary edema, silent myocardial ischemia, sudden cardiac arrest
Who is at risk for atypical MI presentation? - correct answer Women, eldery, diabetics
What does t-wave inversion indicate? - correct answer Ischemia [Show Less]
