Module 6 Flashcards
what personal habits should be asked about in relevant history
Smoking
Diet
Exercise
Alcohol intake
what family history should be asked about in relevant history
Diabetes
Hypertension
CAD
Hyperlipidemia
Fainting; transient loss of consciousness
syncope
Profuse sweating
Diaphoresis
what are possible causes of chest pain
Cardiac Aortic Musculoskeletal Pleural Gastrointestinal Pulmonary Psychoneurotic
what are the four chambers of the heart
Right atria
Right ventricle
Left atria
Left ventricle
what are the four valves of the heart
Two atrioventricular
Tricuspid and Mitral
Two semiluunar
Pulmonic and Aortic
what is the full circulation
Superior and Inferior vena cava
Right atrium Tricuspid valve Right ventricle Pulmonic valve Pulmonary arteries Lungs Pulmonary veins Left atrium Mitral valve Left ventricle Aortic valve Aorta Head and Body
what occurs during systole
Ventricles contract and atria relax
Pressure in the ventricles rises
Blood is ejected
what occurs during diastole
Atria contract and ventricles relax
As ventricular pressure falls below atrial pressure
Blood flows in a relatively passive manner
Then the atria contract to eject the remaining blood
what equipment do you need
Marking pencil
Centimeter ruler
Stethoscope with bell and diaphragm
Sphygmomanometer
what techniques are used
Inspection
Palpation
Percussion
Auscultation
what do you look for in the general assessment
Color- General and Lips and mucus membranes
Ease of respirations
Signs of distress
Blood Pressure- Both upper extremities in at least two positions
what do you inspect for in the extremities
Color Temperature Hair distribution Capillary refill Skin turgor Skin integrity Venous pattern Nails
Dilated and swollen
Evaluate venous incompetence- Trendelenburg test
Varicose Veins
how do you Assess Jugular Venous Distension
Place person in supine position
Note the jugular vein
Gradually raise the head of the bed until the jugular vein is no longer visible in the neck
Sharp, quick dorsiflexion of the foot with the knee slightly bent
Positive sign is calf pain
Homan’s sign
what do you assess the peripheral pulse for
rhythm, contour, amplitude, and symmetry
what are the peripheral pulse locations
Carotid Brachial Radial Femoral Popliteal Dorsalis pedis Posterior tibial
Generally the larger the artery
the greater the expected amplitude
Low-pitched bowing sound over a peripheral vessel
Usually indicates a narrowed vessel
bruit
how do you check the carotid arteries
Listen for bruits
what do you inspect the chest for
Contour
Heaves or lifts
Pulsations
what do you palpate the chest for
Thrills
Pulsations
PMI
2nd RICS @ SB
aortic
2nd LICS @ SB
pulmonic
3rd-5th LICS @ SB
right ventricle
5th LICS @ or just medial to the LMCL
Normal location of PMI in an adult
apical
do you generally percuss the chest
no
how do you auscultate the chest
Make sure room is warm
Make sure stethoscope is warm
Take time to isolate each sound and each pause in the cycle
Avoid “jumping the stethoscope from one site to another
how is sound transmitted
the direction of blood flow
where are specific sounds heard best
over areas where the blood flows after it passes through a valve
auscultation should be performed..
in at least the five cardiac areas
what are cardiac auscultation areas named for
the locations where the valves are best heard
how should assessment be processed
in an systematic order
From the base of the heart to the apex OR
From the apex of the heart to the base
what is the base of the heart
Aortic area
Pulmonic area
what is the apex of the heart
Mitral area
2nd RICS @ RSB
aortic
2nd LICS @ LSB
pulmonic
3rd LICS @ LSB
Erb’s point
4th or 5th LICS @ LSB
tricuspid
5th LICS in LMCL
mitral
how to remember the cardiac areas
All people enjoy their meals
describe S1 sounds
Closure of mitral and tricuspid valves at the beginning of systole
Heard loudest at the apex: Mitral area
Almost synchronous with carotid pulsation
May be “split”
describe S2 sounds
Closure of aortic and pulmonic valves at the beginning of diastole
Heard loudest at the base: Upper precordium
May have a physiologic split
when is S3 normal
< 30 yoa
Pregnancy
when is S3 abnormal
Fluid overload
Mitral or tricuspid regurgitation
Variation during first rapid filling phase during diastole
Heard best at apex
S3
Sound:
Ken - tuc-ky
Slosh-ing in
S1-3
Variation during 2nd rapid filling phase
Heard best at apex
S4
Sound
Ten-nes-see
A stiff wall
S1, S2, S4
when is S4 abnormal
Hypertension
Left venticular hypertrophy
Mitral or tricuspid regurgitation
Mitral valve opening snap
Valvular stenosis
Ejection clicks
semilunar valves
Inflammation of the pericardium
Grating sound heard with the heartbeat
pericardial friction rub
Relatively prolonged extra sounds heard during systole or diastole
heart murmurs
what are causes of heart murmurs
Increased blood flow across normal valves
Forward flow through a stenosed valve
Backward flow through an incompetent valve
how do you describe heart murmurs
Location Timing and duration pitch character intensity
what are the intensity grades of heart murmurs
I: very faint II: faint III: moderately loud IV: loud V:very loud VI: very loud
what is normal for infants
HR very fast
Apical impulse usually in 4th LICS just left of the MCL
Murmurs are frequent in the newborn in the first 48 hours
when is Acrocyanosis normal
in infants is normal
Bluish coloration of hands and feet
Disappears within a few days after birth
what should you watch for in children
squatting
what is common in children
venous hum
Caused by turbulent blood flow in the internal jugular veins
is a physiologic event in childhood
Heart rate varies in a cyclic pattern, usually faster on inhalation and slower on exhalation
sinus arrhythmia
where is the apical impulse in children(<7)
in 4th LICS just left of the MCL until around age 4
what increases throughout pregnancy
Pulse rate gradually increases throughout
At term is 10-15 bpm faster
what gradually falls in the first 16-20 weeks
BP
what are heard in 90% of pregnant women
