Flashcards in cardiac medications Deck (56)
s/s of dig toxicity
nausea, vommiting, anorexia, bradycardia, visual disturbances, cardiac dysrythmias, yellow and green halos
pt on digoxin should do what?
take pulse daily, do not take if HR less than 60
normal serum dig
monitor potassium for (when taking dig)
can lead to toxicity
do not give dig with ??
antacids, makes drug ineffective
antidote for dig toxicity
digoxin immuno fab
hypokalemia and dig
hypokalemia increases effects of drugs and can lead to toxicity
first time someone takes nitro what should you do?
have them laying when they take it then test for orthostatic hypotension
do not apply nitro patches or ointment where?
near pacemaker or ICD
withdrawal symptoms of ca channel blockers and beta blockers
common se of nitroglycerin
HA pt can take tylenol for HA
what do beta blockers do?
decrease HR and myocardial contractility
calcium channel blockers action
relax coronary artery spasm, relaxes coronary artery spasms, and relaxes peripheral arteries, decreases contractility in turn decreases oxygen demands
decrease afterload, decrease peripheral resistance, reduces workload of the heart
Nitro SL tablets may have
stinging or biting feel
sodium channel blockers
decreases sodium influx into cardiac cellls, which decreases the likelyhood of ectopic foci
when administering antidysrythmics what should be done?
IV push or bolus, monitor for hypotension, compare baseline ecg to ecg after drugs are administered
adverse effects of antidysrhythmics
dizziness, fainting, nausea, vomiting
tell patient on antidysrhythmics to avoid
alcohol, caffeine, tobacco
what lab results to monitor with beta blockers?
BUN creatnine GFR AST LDH
what can beta blockers cause in a trauma situation?
side effects/ adverse effects of beta blockers
dizziness, slow hr, changes in bp, palpitations, orthostatic hypotension, confusion, GI upset, constipation
monitor what with alpha-adrenergic receptor blockers?
urine output, less than 600 daily than contraindicated with renal damage
sudden marked decreased in bp and increased hr
daily wts, can lead to edema
how long does it take for AA receptor blockers to work?
up to 4 weeks
side effects of AA blockers
dizziness, lightheadness, drowsiness, impotence, edema (fluid retention is an issue),
African americans should take
AA blockers and Ca channel blockers, beta blockers are not typically effective
asian patients are more susceptible to what?
effects of propanolol
side effects of ACE inhibitors
angioedema, cough, dysgeusia, weakness, hyperkalemia, renal impairment
nis for ACE inhibitors
BUN, creatnine, urine protein, bruising, petichae, bleeding
Teaching: avoid salt substitutes with K in them
rise slowly cause you can have orthostatic hypotension
how to take and record bp
report any occurrences of bleeding
report dizziness longer than a week
take with out food to increase absorption
food taste may diminish during first month of therapy
Hyperkalemia is possible
african americans will not respond to an ace inhibitor unless
it is taken with a diuretic
