Cardiac Flashcards
this occurs when there is a blockage of the coronary arteries
myocardial infarction
does heparin dissolve clots already formed
no - it prevents cloth growth
signs and symptoms of MI
-pain in jaw, back, epigastric (feels like heartburn), shoulder
-SOB
-nausea
-sweating
-pale cool skin
-anxiety
what are the key words to listen for re MI when pt is describing the pain
sudden, crushing, radiating
what are the risk factors for MI
S-stress, smoking, simulants
O-obesity
D-diabetes, HTN
D-diet - high cholesterol (animal fats)
A-african american males & 50+ years old
if troponin is over what number, it means MI occured
0.4ng/ml
what medications are given to lower cholesterol
statins
what are the cautions for statins
no grapefruit
liver toxicity
muscle pain
what is antidote for heparin
protamine sulfate
signs of right sided heart failure
peripheral edema
weight gain
JVD - big neck veins
abdominal growth
signs of left sided heart failure
pulmonary edema (fluid in lungs)
crackles in lungs
pink frothy sputum
orthopnea (difficulty breathing when lying flat)
what causes right sided heart failure
HTN
pulmonary HTN
fibrotic lungs (stiff)
left sided HF
what causes left sided heart failure
weak heart (after heart attack)
CAD
ACS
patient with heart failure who is constipated. what would nurse recommend
a. walking
b. increase fiber
c. stool softeners
d. drink more water
a. walking
b. increase fiber
c. stool softeners
risk factors for heart failure
HTN - #1 risk factor
atrial fibrillation
mitral valve regurgitation
cardiomyopathy
which food item should the heart failure pt avoid
select all that apply
chips
fruits
veggies
grilled chicken and ff
canned beans
bread
canned beans
grilled chicken and ff
chips
all have sodium
a client with CHF took cold medicine for her flu. she presents with new productive cough with pink forthy sputum and worsening crackles
what action should the nurse do first
- assess lung sounds
- give bumetanide IV push
- notify HCP
- clock out for lunch
- give bumetanide IV push
new, sudden, worsening, rapid symptoms
#1 action is furosemide = body dried
priority interventions for pulmonary edema crisis
HOB 45 degrees
Oyxgen
Push furosemide + morphine, positive inotropes
End sodium & fluids — stop IV fluids
what to watch for if pt is on digoxin
take apical 1 min before
look for toxicity - 2.0+ = vision changes & N/V
watch potassium. 3.5 -5.0 is normal
if pt is on furosemide, what do you need to watch for
potassium. K+ wasting
what do beta blockers do for heart
blocks both BP and HR
LOL = LOW
cautions for beta blockers (LOL)
bradycardia
wheezing (asthma & COPD)
bad for HF pts
hides S/S of blood sugar for diabetics
calcium channel blockers do what for heart
calms BP & HR
nitroglycerin is what kind of medication
vasodilator
lisinopril & losartan do what
lowers BP
nursing interventions for heart failure pts - 7
diet - low sodium & fluid
risk for falls - change position slowly
BP & BNP should not increase
elevate legs with pillows
daily weights
sex - only if can do 2 flight of stairs with no SOB
stockings
do you massage pt’s legs if they have CHF
never
what OTC meds can a pt have with HF
none. no NSAIDS, no cough or flu meds, no Antacids
-this is comprised of lipid deposition in intimal layer of artery
-narrows vessel and impairs blood flow
-smooth muscle proliferates, fibrous cap with lipid center
atherosclerosis
what can create chronic endothelial injury which can lead to atherosclerosis
HTN
tobacco use
hyperlipidemia
diabetes
toxins
hyperhomocysteinemia
this is the break down of aminoacids. it can be from diet, lifestyle or hereditary
hyperhomocysteinemia
when the plaque ruptures in artery.
thrombus formation
total occlusion or narrowing of vessel.
what can occur
myocardial infarction
this is the pain that occurs if you have chronic endothelial injury and then you exercise
angina
nonmodifiable risk factors of artherlosclerosis
age
gender - men younger - 55- , men and women- 55+
race - african, native, asian and mexican americans
hereditary - 40-60% genetic disposition
modifable risk factors of atherosclerosis
HTN
tobacco use
sedentary lifestyle
high serum lipids
obese
metabolic syndrome
stress
diabetes
homocysteine
substance abuse
what is metabolic syndrome
high blood pressure,
high blood sugar,
excess body fat around the waist,
and abnormal cholesterol levels.
is LDL or HDL the bad cholesterol
LDL
this occurs when there is complete blockage and damage to vessel, but blockage starts to dissolve
non ST segment elevation MI
why does angina occur
no oxygen to heart but not long enough to cause damage
