LESSON 9 part 2 Flashcards
Muscle aches
myalgia
Give nursing interventions for CAD
Monitor vital signs
Monitor ecg
Monitor labs
Monitor for myalgia
Characterized by episodes of paroxysms of pain or pressure in the anterior chest
Angina Pectoris
What is the cause of angina pectoris
insufficient coronary blood flow
Classification or Types of Angina
Stable angina
Unstable angina
Intractable or refractory angina
Variant angina
Silent ischemia
There is predictable and ‘consistent pain’ that occurs on exertion and ‘relieved by rest and or nitroglycerin’
stable angina
The symptoms increase in frequency and severity and ‘may not be relieved with rest or nitroglycerin’
Unstable angina
There is severe incapacipating chest pain
Intractable or refractory angina
There is pain at rest, with reversible ST segment elevation
Variant Angina
There is objective evidence of ischemia, but the patient reports no pain
Silent Ischemia
Angina is usually caused by
atherosclerotic disease
This ‘can precipitate an attack’ by increasing myocardial oxygen demand
physical exertion
This can cause ‘‘vasoconstriction and elevated blood pressure’’ with increase oxygen demand
exposure to cold
Gives long term and short term reduction of myocardial oxygen consumption through selective vasodilation within three minutes
nitroglycerin
blocks the beta-adrenergic stimulation of the heart
beta blockers
have negative inotropic effects
calcium channel blockers
Prevent platelet aggregation
antiplatelet
inadequate blood supply to peripheral tissues causes ______
pallor
another term for unstable angina
crescendo angina/ pre-infarction angina
what position is allowed if patient has angina?
semi fowler position
nitroglycerin is given at what route?
sublingual
nitroglycerin should only be given with how many doses and every what minutes?
3 doses only, every 5 minutes
what is the mg of a nitroglycerin
0.6 mg
abnormal contraction; squeezing out of blood by arteries
vasospasm
it is absorbed in the small intestine
bile acid
example of a bile acid sequestrants
cholestyramine (questran)
medicines that help lower your LDL (bad) cholesterol
bile acid sequestrants
depolarization:
______ out ______ in
potassium OUT
sodium IN
another term for unstable angina
crescendo angina
another term for variant angina
prinzmetal
how many mg of nitroglycerin should be given
0.6
angina that is caused by coronary VASOSPASM
variant angina
