Exam 3 Flashcards
Heart health history questions
chest pain, SOB, skin color changes, fatigue, edema, past medical/family history
Heart assessment
- look for apical impulse
- look for heave
- palpate precordium
Heart assessment: apical pulse
4th or 5th intercostal space, midclavicular line
Heart assessment: heave
sustained forceful thrusting of ventricle, abnormal
Heart assessment: palpate pericardium
- use palmar aspect of 4 fingers
- L sternal border, apex, and base
- search for any pulsations
- a thrill is a palpable vibration
- should not feel any pulsations - means turbulent blood flow
Anatomy of the heart
- layers: pericardium, myocardium, endocardium
- 2 atriums
- 2 ventricles
- 2 AV valves
Blood flow through the heart: oxygenated
lungs, pulmonary vv, L atrium, bicuspid AV valve, L ventricle, aortic semilunar valve, aorta, body tissues
Blood flow through the heart: deoxygenated
body tissues, vena cava, R atrium, tricuspid AV valve, R ventricle, pulmonary semilunar valve, pulmonary aa, lungs
Cardiac cycle
Diastole, systole, diastole again
Diastole process
ventricles relax, AV valves open, pressure higher in atria, blood pours rapidly into ventricles, toward end, atria contract and push out last amount of blood
Systole process
- ventricles full of blood = higher pressure in ventricles than atria
- AV valves swing shut (S1) = beginning of systole
- ventricle walls contract, builds pressure
- valves open, blood ejected rapidly
- after ventricle blood is ejected, valves swing shut, closure of SL valves = S2
S1 heart sound
- occurs with closure of AV valves
- signals beginning of systole
- usually loudest at apex
S2 heart sound
- occurs with closure of semilunar valves
- signals end of systole
- loudest at base
Murmurs
- noisy flow, gentle, blowing, swooshing sound
- blood circulating normally makes no sound
- some conditions create turbulent blood flow and collision currents
Auscultation spots
aortic valve, pulmonic valve, Erb’s point, tricuspid valve, mitral valve
Aortic valve location
2nd ICS - R sternal border
Pulmonic valve location
2nd ICS (L sternal border)
Erb’s point lcoation
3rd ICS - L sternal border
Tricuspid valve location
4th or 5th ICS - L sternal border
Mitral valve location
5th ICS (mid-clavicular line)
Heart Auscultation process summary
Listen with diaphragm of stethoscope
- firmly on chest, 5 areas
Locate apical pulse: 5th ICS, MCL
- count x 30 seconds
Identify S1 + S2
Listen for murmurs with bell
Heart auscultation pattern
z pattern from base to apex
If rate/rhythm of heart is irregular,
check for pulse deficit by auscultating the apical beat while simultaneously palpating radial pulse
Carotid arteries assessment
palpate each artery one at a time, use gentle pressure
Carotid artery assessment findings
- should be normal strength and same bilaterally
- diminished pulse
- increased pulse
Diminished pulse can mean
cardiogenic shock
Increased pulse feels
full + strong, can be from exercise anxiety fear
Jugular veins
lets you assess central venous pressure and judge hearts efficiency as a pump
Jugular veins assessment process
- stand on right side of patient
- position patient supine at 30-45 degree angle
- use pen light to see better
Jugular veins findings
- may or may not see jugular
- should disappear by 45 degrees
- full distended jugular vv above 45 degrees signify increased CVP and heart failure
PVS
vv and aa to perfuse the lower part of the body + carotid and jugular veins
Lymphatic system
- retrieves excess fluid + plasma proteins
- forms part of immune system
- absorb lipids from small intestine
- lymph nodes
Pulse assessment locations
brachial, radial, popliteal, posterior tibial
Pulse strength = 0
0 = absent
Pulse strength: 1+
- weak or thready
- hard to palpate
- associated with decreased PO, peripheral arterial disease, aortic valve stenosis
Pulse strength: 2+
expected, normal, easy to palapte, strong
Pulse strength: 3+
- full and bounding
- pounds under fingertips
- associated with exercise, anxiety, fever, anemia, hyperthyroidism
Bilateral edema
may be related to heart disease
Unilateral edema
may be related to DVT
Swelling/edema +1
mild pitting, slight indentation, no perception of swelling
Swelling/edema +2
moderate pitting, indentation subsides rapidly
Swelling/edema +3
deep pitting, indentation remains for a short time, legs swollen
Swelling/edema +4
very deep pitting, indentation lasts a long time, legs grossly swollen
Inspect and palapte PVS
- color and temp of extremities
- hair distribution
- swelling/edema
- capillary refill
Unexpected findings of PVS
- PAD arterial
- PVD venous
- DVT
PAD arterial
- leg pain/cramps
- skin changes on arms./legs
- legs cool to touch
- swelling in arms/legs
- lymph node enlargement
- medications
- smoking history
- shiny dry leg skin with sparse hair growth
PVD venous
- aching tiredness in legs
- varicosities
- lower leg edema
- brown discolored skin
- ulcers at ankles
- weepy pruritic dermatitis
- shallow non-healing ulcers in lower leg
DVT
- immobility
- localized tenderness
- sharp deep pain
- warm skin
- pitting edema in leg
- tenderness to severe pain in leg
- cancer
- obesity
- hormones
S3 heart sound
due to vibration of ventricles that resist early, rapid filling
S4
due to vibration of noncompliant ventricles when atria contract and push blood into them
Major risk factors for heart disease and stroke
high blood pressure, smoking, high cholesterol, physical inactivity
Developmental changes: before birth
- formaen ovale allows oxygenated blood from placenta to be shunted to L side of heart
- ductus arteriosus shunts blood into aorta
Developmental cardiovascular system changes: aging adults
- increase in systolic bp
- increased risk fo dysrhythmias
- CO decreases
Signs of heart disease in children
poor weight gain, DOE, developmental delay, tachycardia, tachypnea, cyanosis, clubbing
In pregnant patients, resting pulse rate
increases 10-20bpm
- bp decreases
In older adults, systolic bp
rises and orthostatic hypotension may occur
3 mechanisms keep blood moving toward the heart
- contraction of skeletal mm
- pressure gradient caused by breathing
- intraluminal valves - one direction
Organs that aid the lymphatic system
spleen, tonsils, thymus
Spleen
- destroys old blood cells
- make antibodies
- stores RBCs
- filters organisms
Tonsils
- respond to local inflammation
Thymus
develops T lymphocytes
Peripheral artery disease causes
smoking, diabetes, obesity, elevated cholesterol, HTN
COVID-19 can increase risk for
DVT
In healthy infants and children, lymph nodes are
commonly palpable
PVS findings in pregnant women
- diffuse bilateral pitting edema
- varicose veins
PVS findings in aging adults
