Part 4 Flashcards
Physical exam definition
Process by which the clinician investigates the body of a patient for signs of disease
Always approach patients from the…
right (patient right)
128 Hz tuning fork
Larger fork that tests for vibratory sensation
512 Hz tuning fork
Smaller tuning fork to allow for Weber & Renne’ hearing test
Pan-optic opthalmoscope
Gives a more magnified image of the retina
Diaphragm of stethescope
Large dial on end of stethoscope that listens to high pitched sounds
Bell of stethoscope
Small dial on end of stethoscope that listens to low pitched sounds
The 5 vital signs (sometimes a 6th is included)
1) Temp
2) Blood pressure
3) Respiration rate
4) Heart Rate
5) BMI
6) SOMETIMES Pulse ox
Temperature is regulated by what organ
hypothalamus
Normal oral temp
98.6F/37c
5 ways to measure temp
1) oral
2) Axillary
3) Rectal (patient unconscious, restless, cannot close mouth)
4) Tympanic membrane
5) laser thermometer of the forehead temporal artery
Hypothermic thermometer
Accurate for temperatures a normal thermometer is not, below 94 degrees F
Noninfectious causes of pyrexia
- ovulation
- thyroid storm
- drug effect
- trauma
- cancer
Hyperpyrexia
Fever greater than 104 degrees F, typically resulting from infection
Hypothermia
Temp less than 95 degrees F, exposure to cold, shock, hypothyroidism, hypoglycemia
6 pulse sites
1) radial (easiest)
2) carotid (have to listen for presence of plaque that could be released by pressure)
3) femoral (at about the femoral triangle)
4) apical (on the heart, says nothing about perfusion)
5) Dorsalis pedis
6) Posterior tibial pulse
Carotid baroreceptor mechanism and nerve responsible
Massaging of carotid can cause baroreceptor reflex to stimulate thanks to glossopharangeal nerve that results in a drastic drop in blood pressure and syncope episode
Sinus tachycardia and some common causes
Rapid regular >100 beats, caused by
- heart disease
- fever
- exercise
- anemia
- dehydration
- hyperthyroidism
- drugs
- smoking
-anxiety
Sinus bradycardia and common causes
Slow regular <50 bpm, caused by
- heart disease
- hypothyroidism
- irregular electrolytes
- athlete
Pulsus alternans deinition and cause
Alternating strong and weak pulse, indicates left ventricular heart failure
Pulsus bisferiens and cause
Biphasic pulse, indicates aortic valve problem
Dicrotic pulse and cause
2 distinguishable palpable pulses, indicates low cardiac output
Pulsus parvus et tardus definition and cause
Pulse is weak and has late carotid upstroke, caused by aortic valve stenosis
Pulsus paradoxus definition and cause
Typically SBP falls 3-10mm during inspiration, pulse gets weaker, caused by asthma, COPD, etc…. Note this has NOTHING TO DO WITH PULSE BUT RATHER BP
