Digoxin (Lanoxin) is called what, and does what?, and therefore makes it what?
a cardiac glycoside, it increases cardiac output by slowing heart rate and increasing force of contraction. This is a POSITIVE inotropic action
what keeps fluid in the vascular system
albumin

arterial
an arterial clot is called what and looks like what
ascemia, sudden pain, distal pulses abs, numb, tingling cramping and grangreous
what are some negative inotropics, and what does this mean
beta blockers and calcium channel blockers, this means that they weaken the force of the heart rate, muscles dont have to work as hard, and decreases O2 demand
what meds treat afib
beta blockers, cal channel blockers and anticoagulants
what do ace inhibitors/angiotension receptor blockers (ARBs) do
block vasoconstriction. the 1st line to decrease afterload and promote fluid and sodium loss. they supress the renin angiotension aldosteron system. Also reduce preload and afterload
The nurse is reviewing a patient's diet. The patient has been diagnosed with hypertension. The nurse recommends reducing or avoiding caffeine for patients with hypertension because:
caffeine increases the heart rate and causes vasoconstriction
contractility is influenced by what and therefore you need to watch what medications
