Cardiovascular System Flashcards
Define cardiovascular
the heart and blood vessels
List the general assessment tools used for the cardiovascular system
inspection, palpation, auscultation, and in some rare cases percussion
What is an important exam that is directly related to the cardiovascular system when a pt is experiencing abnormalities?
ophthalmoscopic exam of the eyes allows for the only direct visualization of the arteriovenous system
What is hypercholesterolemia?
high cholesterol
Hypercholesterolemia may cause….
xanthelasma and arcus senilis
What is xanthelasma?
yellowish plaques on eyelids
What is this?
xanthelasma
What is arcus senilis?
extreme whitish ring around the iris
common in people 40 years old and younger
What is this?
arcus senilis
Doing an opthalmoscopic exam when assessing the cardiovascular system may help diagnose….
hypertension or diabetic retinopathy (proliferative and nonproliferative)
What is this?
copper wiring, indicitive of hypertension
What is this?
nonproliferative diabetic retinopathy, visible with the “tortorous” blood vessels
Doing an oral exam when assessing the cardiovascular system may help diagnose…
petechiae on the palate, often seen with infective endocarditis (this infection begins in the oral cavity)
What is JVD? What is it indicitive of?
bulging/distention of the jugular vein
indicitive of CVP, which is in the right atrium of the heart
The angle of Louis is important for calcuating _____
JVD
What is another name for the angle of Louis?
sternal angle or manubrium sternal angle
Is the jugular notch easily palpable on all patients?
yes
Where can you find the angle of Louis?
2nd rib is in line with it
How far is the heart from the angle of Louis?
5cm inferior to the angle of Louis is the base of the heart
base of heart = superior portion of heart
What is the “point” of the heart called?
the apex
If you detect JVD through observation, it is time to measure for _____ next
JVP
If you detect JVD through observation, it is time to measure for JVP next
How do you measure JVP?
bed at 30-45 degree angle
find the angle of Louis and position a ruler on the angle
use anything else vertical, like a tongue depresser and line that up with the highest point that you see the jugular vein bulging
you’re essentially making a right angle, take the height and add 5cm to the height
JVP= anything larger than 8cm is too high and deemed abnormal
6-8cm is WNL and CVP is okay
Which patients should you be measuring JVP?
senior patients (60+ years old)
What is a normal JVP?
6-8cm
What is an abnormal JVP?
8cm water or higher
When measuring JVP, what else should you be doing in this area?
auscultate and palpate the carotid pulse
What does COPD stand for?
chronic obstructive pulmonary disease
What does COPD include?
usually includes emphysema and chronic bronchitis
What is emphysema?
air sacs of lungs are damaged and enlarged, causing breathlessness
How does COPD affect PMI?
PMI will be shifted because the heart gets displaced from the enlarged lungs (over inflated)
PMI is usually lower in cases of COPD and more to the right
the apex of the heart hits the ________ chest wall every time it beats. This is called the ____
the apex of the heart hits the anterior chest wall every time it beats. This is called the PMI
Describe where you are palpating when assessing PMI
palpate till the 5th intercostal space and then feel for the mid-clavicular area on the left side
What does PMI stand for?
Point of Maximal Impulse
What is normal PMI?
width of impulse should be 2-3cm
What is an abnormal PMI?
larger than 3cm, this is indicitive of cardiomegly
What is cardiomegaly?
enlarged heart
How many fingers should you palpate with when assessing PMI?
4 fingers, feel for the apex
What does SV stand for?
stroke volume
What does a vigourous stroke volume mean? Example of cause?
increased stroke volume
blood volume is being ejected with each beat
vigorous exercise would appear as a bounding pulse
How do you confirm heaves or thrills after palpation?
with a stethoscope
How do you assess for thrills? What do thrills indicate?
palpate with metacarpals to feel for vibrations, called thrills
this is indicitive of turbulent blood flow
How do you assess for heaves? What are heaves/what does this mean?
palpate with your hand to the heart for heaves
heaves are sustained impulses
this usually means that ventricles are enlarged
What are the 4 positions for ausculatation of the heart?
1) supine
2) left lateral decubitus
3) upright
4) upright leaning forward
List the pt postion(s) for a normal heart auscultation
supine and upright
both of these positions you should be able to hear all areas of the heart
List the pt position(s) for abnormal heart auscultation (or was unheard in other positions)?
left lateral decubitus and upright leaning forward
only use these positions if:
- you cannot hear the mitral valve area or base of heart
- if it sounds abnormal
the b of “lub” is _________ than p in “dup”
the b of “lub” is harsher than p in “dup”
What is the first sound of the heart?
S1= closure of the AV valves “lub”
AV= atrioventricular valve
mitral valve + tricuspid valve.
What is the second sound of the heart?
S2= closure of the semilunar valves “dup”
What are the 4 valve areas of the heart?
aortic, pulmonic, tricuspid, and mitral valve areas
T/F
The mitral closes slightly before the tricuspid, and aortic slightly before the pulmonic, so there are 4 sounds, but indistinct
true
Which heart valve area is the loudest?
mitral
What position should the stethoscope be held when auscultating the heart?
angled slightly anteirorly
Which valvular area should you start with when auscultating the heart?
aortic
List the order of valvular areas you should auscultate
1) aortic
2) pulmonic
3) tricuspid
4) mitral
