Cardiovascular drugs Flashcards
drug allergy, hyponatremia,
hypokalemia, cirrhosis and renal,
liver and adrenal gland dysfunction is contraindication of what medication?
Acetazolamide
The nurse is assessing the client for possible evidence of digitalis toxicity. The nurse acknowledges that which is included in the signs and symptoms for digitalis toxicity?
Pulse below 60 beats/min and irregular rate
When a client first takes a nitrate, the nurse expects which symptom that often occurs?
Headaches
Total loss of blood supply d/t necrosis or death of cardiac tissue
Myocardial Infarction
The heart requires a large amount of ______ to meet the demands placed on it
Oxygen
Most preferred medication used in Angina Pectoris (insufficient blood supply) type of MI
Morphine
Oxygenated blood is delivered to the brain through openings in this part of the heart
Aortic arch
Describe the difference in chest pain vs. muscle pain:
Muscle pain is localized
Chest pain radiates
Describe the difference in chest pain vs. muscle pain:
Muscle pain is localized
Chest pain radiates
Poor blood supply to an organ
Ishchemia
Poor blood supply to the heart disease
Ischemic heart disease
Anterior infarct can inhibit this ventricle from supplying oxygenated blood to systemic circulation
Left ventricle
intense but subsides
within 15 mins of rest or medication and caused
mainly by atherosclerosis and can be triggered
by exertion or stress (cold, emotions) and
exacerbated by smoking, alcohol, coffee and
some drugs.
Chronic Stable Angina
early stage of progressive
artery disease characterized by pain increasing
in severity and frequency and may even occur at
rest
Unstable Angina
from spasms of the
smooth muscle that surrounds the coronary
arteries and occurs at rest without any triggers
but usually occurring at the same time of day
Vasospastic Angina
BP measure that refers to the contraction of the heart
Systolic
BP measure that indicates when the heart is at rest
Diastolic
Effect of alpha 1 drugs
Vasoconstriction
Reduce BP by reducing HR through beta 1 blackade; Cause reduced secretion of renin. Ex- Propranolol, Atenolol
Beta alpha 1 blockers
