  1. what are the 5 vital signs
    • temperature
    • pulse
    • blood pressure
    • respirations
    • pain
  2. baseline =
    ususal state of health
  3. UAP =
    unlicensed assistive personnel
  4. nurse cannot delegate what?
    the first set of anything
  5. temperature =
    heat produced - the heat lost
  6. normal range for temp =
    97.0-99.5
  7. what regulates temp
    hypothalamus
  8. mechanisms for heat production =
    • metabolism
    • shivering
    • piloerection
    • exercise
    • hormones
  9. what are some development considerations for temperature
    • neonates cannot shiver (have brown fat)
    • elderly have lower baseline temp
    • kids sensitive to changes in environmental temp
  10. pyrexia
    fever 100.4 or greater
  11. what does the hypothalamus do in regards to temp
    reset the set point for body temp
  12. febrile =
    feverish
  13. afebrile
    no fever
  14. FUO
    fever of unknown origin
  15. neurogenic fever
    caused from damage to hypothalamus
  16. antipyretics
    ibuprofen, acetaminophen, aspirin
  17. what hapens to pulse and resp with fever
    they go up
  18. oral temp avg
    98.6 or 37c
  19. oral temp advantages and disadvantages
    • advantages
    • comfortable, easily accessible, accurate surface temp
    • disadvantages
    • must wait 30 min after food, drink , smoke etc
    • must hold in mouth in posterior sublingual pocket
  20. rectal temp avg
    99.5 or 37.5
  21. rectal advantage and disadvantage
    • advantages = reliable core temp
    • dis = can't use when diarrhea, rectal surgery, bleeding, impaction, low wbc,
    • can stimulate vagus nerve not on newborns
  22. axillary avg temp
    97.7 or 36.5c
  23. axillary advantages
    safe, inexpensive, used with newborns and unconcious
  24. axillary disadvantages
    positional, long time with glass, 5-10min,
  25. tympanic avg temp
    99.5 or 37.5 c
  26. tympanic advantages
    accessible, minimal positioning, unaffected by eating and drinking, provides core temp
  27. tympanic disadvantages
    • inaccurate with position
    • need to remove hearing aids
    • dificult in children < 3months
  28. pulse locations
    • temporal
    • carotid
    • brachial
    • radial
    • femoral
    • popliteal
    • posterior tibial
    • dorsalis pedis
  29. parasympathetic NS does what to HR compared to symathetic
    • para slows
    • sympathetic speeds up
  30. apical auscultate how long
    one minute
  31. adult norm P
    60-100 bpm
  32. tachycardia
    > 100 bpm
  33. bradycardia
    < 60 bpm
  34. pulse amplitudes =
    • 0 = absent
    • 1+ = weak, thready
    • 2+ = normal
    • 3+ = increased
    • 4+ = bounding
    • doppler
  35. which is an active process in respirations
    inspiration
  36. tachypnea
    > 24 min
  37. Bradypnea
    < 10 min
  38. Dyspnea
    difficult or labored breathing
  39. BP =
    CO x peripheral resistance
  40. CO =
    stroke volume x HR
  41. stroke volume =
    volume of blood pumped by LV one time
  42. BP  determined by
    • CO
    • peripheral resistance
    • volume
    • viscosity
    • elasticity of vessel walls
  43. normal BP for adult
    100-120/60-80
  44. othostatic hypotension =
    systolic drops 20mmHg diastolic drops 10mmHg after 3 minutes
  45. orthostatic hypotension is caused by what
    peripheral vasodilation w/o compensatory rise in CO
  46. BP cuff size standards =
