FCCN Level I Questions with 100% Correct Solutions Graded to Pass

Tachycardia - Decrease coronary artery perfusion by decreasing filling time. Bradycardia - Decreasing the frequency of coronary filling. S1 - Closure of mitral and tricuspid valve. Ventricular systole. S2 - Closure of aortic and pulmonic valve. Ventricular diastole. S3 - Heard between S1 and S2. Systole - Pressure in arterial during ejection of blood in the circulation. Diastole - Pressure remain in arterial, measuring the relaxation of the ventricle. Heart failure - Impaired cardiac functioning and or excessive workload demand. Forward movement is restricted. Increase preload-give diuretics, diurese. Increase afterload- give ACE, ARBs to dilate artery, Calcium chan blockers-improve contractility. Ss:sob, edema, cool skin, n/v, fatigue, PND, anorexia. Might result to hypertrophy. Left heart failure - Dyspnea, orthopnea, arrythmia, fluid in the lungs, crackles, wheezing. Right heart failure - Pheripheral edema, ascites, weight gain, cirrhosis. Edema - not part of intravascular volume Systolic dysfunction - Ventricle not properly ejecting blood into circulation during ventricular contraction. Diastolic dysfunction - Ventricle not relaxing/ not filling properly
