10 minute topic Cardiovascular medications Flashcards
Nitroglycerin use/function
stable angina
vasodilator
decreases O2 demand
Can be used in HF
Nitroglycerin use in variant angina
prevents or reduces coronary artery spasm and that provides more oxygen to the myocardium itself
Nitroglycerin cautions
use cautiously with antihypotensives due to risk of orthostatic hypotension
IV nitroglycerin
given to control angina that did not respond to other meds or to keep BP low
Nitroglycerin PT teaching
HA is common Orthostatic hypotension Flushing is common Reflex tachycardia will develop a tolerance (need to have a nitrate free period)
Nitroglycerin interactions with food
ETOH causes hypotension
Instructions for nitrate use
Chest pain → stop activity & rest →sublingual nitro x3, 5min apart, →unrelieved 911
Nitroglycerin storage
Glass container in a dark place, can’t get too warm so not in a pants packet
metoprolol tartrate (Lopressor) & atenolol (Tenomin) category
Beta blockers
metoprolol tartrate (Lopressor) action
antidysrhthmic (blocks conduction through SA and AV nodes) and antihyperstensive
Decreases heart rate and contractility therefore it decreases oxygen demand by the myocardium
Blocks renin release
metoprolol tartrate (Lopressor) nursing consideration
monitor bradycardia and hypotension
Use in caution with HF
Avoid use in PT’s with asthma due to bronchospasm
Can mask hpyoglycemic sx in DM
streptokinase (Streptase) alteplase (Activase), Reteplase (Retavase) category
thrombolytics
thrombolytics action
these medications dissolve clots that have already formed
thrombolytics used to tx what
treat MI (with MI best to give within 6 hours of infarct), DVT, massive pulmonary emboli and ischemic strokes
thrombolytics nursing considerations
do not use in active bleeding
monitor PT, aPTT, INR, fibrinogen levels, CBC
Monitor for allergic reaction (urticaria, itching, flushing)
ASA (salicylic acid), enteric coated is called (Ecotrin), clopidogrel (Plavix) category
Antiplatelet agents
Antiplatelet agents use
Acute MI- Primary
Prevention of reinfarction
Prevention of stroke
Acute coronary syndromes
Antiplatelet agents nursing considerations
can cause GI upset
use cautiously in PT’s with ulcers
Tinnitus is possible side effect or indication of toxicity
Antiplatelet agents teaching
take with food
report tinnitus
increased bleeding risk
Eptifibatide (Integrilin) category
Glycoprotein IIB/IIIA inhibitors
Glycoprotein IIB/IIIA inhibitors use
prevent the binding of fibrogen, in turn by blocking platelet aggregation. It is used in combination with ASA therapy
Glycoprotein IIB/IIIA inhibitors nursing consideration
can cause active bleeding, need to report s/sx of bleeding
Diuretics use
reduce preload
