FCCN Level I Questions And Answers 100% Correct!!

Tachycardia - ANSWER-Decrease coronary artery perfusion by decreasing filling time. -Decreasing the frequency of Bradycardia - ANSWER coronary filling. S1 - ANSWER-Closure of mitral and tricuspid valve. Ventricular systole. S2 - ANSWER-Closure of aortic and pulmonic valve. Ventricular diastole. S3 - ANSWER-Heard between S1 and S2. Systole - ANSWER-Pressure in arterial during ejection of blood in the circulation. Diastole - ANSWER-Pressure remain in arterial, measuring the relaxation of the ventricle. Heart failure - ANSWER-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 - ANSWER-Dyspnea, orthopnea, arrythmia, fluid in the lungs, crackles, wheezing. Right heart failure - ANSWER-Pheripheral edema, ascites, weight gain, cirrhosis. Edema - ANSWER-not part of intravascular volume Systolic dysfunction - ANSWER-Ventricle not properly ejecting blood into circulation during ventricular contraction. Diastolic dysfunction - ANSWER-Ventricle not relaxing/ not filling properly Hypovolemia - ANSWER-Decrease blood volume. Deficient venous return result from hemorrhage, burns, diarrhea, polyuria (DI). sS: cool, clamped, low bp, tachy. Decrease preload, -tx: colloids, blood. increase afterload. Tx: inotropic, ex dopamine, vasodilator, tx shock etiology. Cardiogenic shock - ANSWER-Heart suddenly cannot pump blood, caused by severe heart attack. SS: SOB, tachycardia, cool, pale, clamped, low bp, pulmonary edema. High afterload, low preload, tx: reperfuse- IV, blood, aspirin, oxygen, nitro, morphine, surge
