Mod. 1 Vital Signs
Question | Answer |
---|---|
Vital Signs | "Cardinal Signs"; indicate: pt. condition, presence of life, disease; crucial to correct dx.; temperature, pulse, respirations, blood pressure |
Body Temperature | balance between heat produced/heat lost in body; maintained by hypothalamus |
heat production | muscle contraction, metabolism, fever, emotional states |
heat loss | urine, feces, water vapor from lungs, perspiration(evaporation), conduction, convection, radiation |
conduction | transfer of heat from one object to another through contact |
convection | transfer of heat through air currents |
radiation | transfer of heat in form of waves |
temp. sites | oral, rectal, axillary, aural(tympanic), skin |
temperature range | 97-99 degrees farenheit |
oral temperature | most convenient; may be affected by eating, drinking, smoking, chewing gum, talking |
rectal temperature | most accurate, 1 degree higher than oral; used commonly in infants/young children, unconscious pt., mouth-breathers; DO NOT USE in NEWBORNS; note site on chart |
axillary temperature | 1 degree lower than oral; use in toddlers/preschoolers, mouth-breathers/mouth problems; note site on chart |
aural (tympanic) temperature | easily accessible; good for children under 6, uncooperative pt., pt. who can't take oral temp. |
pyrexia | fever, above 100.4 degrees F; heat prod. > heat loss |
hyperpyrexia | temp above 105.8 degrees F; serious condition; above 109.4 generally fatal |
hypothermia | body temp below 97 degrees F; heat loss > heat prod. Below 93.2 generally fatal |
low-grade fever | temp between 99 deg. F and 100.4 deg. F |
temperature variations | time of day (lower overnight/morning), age(higher infants/children, lower/elderly), exercise(higher), emotional states(higher), environment(cold/lower, hot/higher), pregnancy(higher) |
febrile | describes pt. w/ fever |
afebrile | describing pt. w/o fever |
stages of fever | onset, course, subsiding |
