_____ is a process in which the ventricles dilate, hypertrophy
and become more spherical. this process is driven primarily by
SNS and RASS activation Correct Answers cardiac remodeling
_____ reduced venous pressure which decreases preload to
improve cardiac output, decrease congestive symptoms and
improve exercise capacity Correct Answers vasodilators
______ exerts a positive inotropic action on the heart. that is, the
drug increases the force of ventricular contraction, and can
therby increase cardiac output Correct Answers digoxin
______ reduce blood volume, decrease venous pressure, arterial
pressure(afterload), pulmonary edema, peripheral edema, and
cardiac dilation which help patients with heart failure Correct
Answers diuretics

Answers no they are negative inotropes and can worsen heart
failure
are thiazide diuretics effective in patients with decreased
glomerular filtration? Correct Answers no, the patient requires

can digoxin and verapamil be used together Correct Answers
verapamil can increase digoxin levels by 60% leading to digoxin
toxicity
, contrast dihydropyridines and nondihydropyridines Correct
Answers dihydropyridines work on arterioles and non-
dihydropyridines work on arterioles and heart
define afterload Correct Answers the load against which a
muscle must overcome in order to contract
define preload Correct Answers the arterial pressure that the
left ventricle must overcome to eject blood
dehydration from diuretic use can promote thromboembolism.
