Level 4 - Exam 1: Heart Failure Questions and Answers Already Passed While assessing a 68-year-old with ascites, the nurse also notes jugular venous distention (JVD) with the head of the patient's bed elevated 45 degrees. The nurse knows this finding indicates a. decreased fluid volume. b. jugular vein atherosclerosis. c. increased right atrial pressure. d. incompetent jugular vein valves. ANS: C The jugular veins empty into the superior vena cava and then into the right atrium, so JV...

Cardiac output correct answer: Volume of blood ejected per minute; 4-8 liters per minute; dependent on body size Cardiac index correct answer: Compares individual differences in the body; computed by cardiac output/body surface area; 2.5-4 liters per minute Stroke volume correct answer: Amount of blood per beat; cardiac output/heart rate Ejection fraction (EF) correct answer: The percentage of blood emptied from the left ventricle during systole (normal 60%) (below= SOB, crackles, a...

what is the most common cause of heart failure? specifically left sided? right sided? - correct answer -MC is CAD (coronary artery disease) -L sided: *CAD* & HTN -R sided: *L sided HF* & pulmonary dz decreased ejection fraction, thin ventricular walls, dilated LV chamber, and an S3 gallop (filling of dilated ventricle) is associated with systolic or diastolic heart failure? - correct answer systolic (MC form of CHF) *(the sound is actually heard in the diastole though) -memory trick: ...
