Exam 2 Flashcards
(132 cards)
general survey
physical appearance, body structure, mobility and behavior
physical appearence
age appropriate, sexual development, alert and oriented, skin tone, facial features are symmetric
body structure
height normal, adequate nutrition, weight, symmetry, posture, position, body build
mobility
gait and range of motion
behavior
facial expression, mood and affect, speech, dress, personal hygiene
when is body temp at low and high
diurnal cycle= 1-1.5 degree change with trough early morning and peak late afternoon to eve
Hyperthermia
Pyrogens secreted by bacteria during infection, tissue breakdown after tissue injury or death, neurological disorders that increase pressure on the brain
Hypothermia
Prolong exposure to cold, room temp IV fluids infused rapid, induced medically to decrease damage to tissue
Pulse assessment
Stroke volume, rate, rhythm, force, elasticity
Stroke volume
Amount of blood pumped by the heart with every beat
Rate of pulse
Normal 60-100 bpm
Bradycarida less than 60 bpm
Tachycardia greater than 100 bpm
Force of pulse
4 point scale, weak to bounding
Elasticity of pulse
Artery should feel straight springy and resilient
What causes weak pulse
Heart failure, hypovolemia, hypothermia, severe aortic stenosis
What causes bounding pulse
Fever, anemia, hyperthyroidism, bradycardia, aging, atherosclerosis
Systolic pressure
When heart contracts
Diastolic pressure
When heart is at rest
Pulse pressure
Difference btw systolic and diastolic pressure which reflects stroke volume (30-40 mm/hg)
Mean arterial pressure
The pressure that forces blood into tissues averaged over cardiac cycle, normal 80-100 mm/hg
SBP +2(DBP) / 3 = MAP
what all influences blood pressure?
Age-gradual rise through childhood into adult years, Race- a black adult’s BP is higher than a white adult; hypertension is twice as high among blacks than whites, Weight- higher in obese, Emotions- increase BP while emotions are elevated, Gender- after puberty females are lower than males; after menopause females are higher, Diurnal rhythm- trough in morning and peak in late afternoon and early eve., Exercise- increases and then back to resting BP 5 mins. after exercise stopped, Stress- increases with stressors, such as pain, occupational stress, lifestyle stress
Cardiac output
as more blood is pumped into blood vessels (increased CO), BP increases
Peripheral vascular resistance
constricted blood vessels increases BP because heart has to force blood against the increased resistance
Volume of circulating blood
more blood circulating or fluid in the blood circulating; greater BP
Viscosity
more blood cells and elements in blood; greater BP
