Warfarin prevents clot formation in the atria of clients with atrial fibrillation."

The nurse is preparing to administer digoxin to a client with heart failure. The nurse obtains an apical pulse rate for 1 minute and determines a rate of 52 beats/minute. What is the first action by the nurse?

Withhold the medication and notify the physician of the heart rate.

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

what is stroke volume

amount of blood out of ventricles with each beat

how to treat a venous occlusion

anticoagulants, complete bedrest,elevate extremity, warm wet packs to area

do NOT elevate with peripheral disease?

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

calcium. cal channel blockers therefore need to be used carefully in HF patients

whats a blood pressure formula

cardiac output x peripheral resistence

signs of PE

decreased O2, increased HR, heart attack like pain, short of breath

A nurse is caring for a client with left-sided heart failure. To reduce fluid volume excess, the nurse should anticipate using:

edema, engorged liver,decreased kidney function, ascites (from organs getting full) JVD, and even GI tract not good due to it being engorged as well

what is preload

filling pressure right before heart contracts

what is the lubb, then what is the dubb, in a heart beat

lubb is the 1st sound, which is systole, the 2nd sound dubb is diastole

normal is greater than 55%, 60-70% is what we like, but in end stage HF patients, 10%

S/S or pernicious anemia

the afterload is the: and what meds help:

systolic BP, and is the resistance, any sort of vasoconstriction, medications that help are dilators (nitrates)

what is the ejection fraction

the % of blood ejected from left ventrical

how do calcium channels blockers work and who uses them most

they block calcium ions block calcium ions, dialate heart vessels and therefore decrease the workload of the heart, clients with arrhythmias use these. they increase preload

iorn is usually ordered

tid 30 mins before meals

s and s of sickle cell anemia

tissue pain, ischemia, swelling, fever

what two things counter act with iron

vit d and calcium
