  46. What is the 1st Korotkoff sound during BP?
    The 5th?
    • 1st - systole (clear tapping heard by the opening of the artery and blood flowing in)
    • 5th - diastole (silence)
  47. How would you find the proper size blood pressure cuff for a client?
    • Bladder length = 80% of the arm circumference
    • Bladder width = 40% of the arm circumference

    *The bladder is only the inflatable portion of the cuff, not the entire length.
  48. How high do you inflate the blood pressure cuff before realsing the air?
    20-30 mm beyond the point of brachial pulse obliteration
  49. How long do you wait between taking BP measurements in teh same arm?
    15 seconds
  50. Your client has a higher BP in the right arm than the left, which measurement do you use?
    Always use the higher of the two measurements
  51. If you did not pump the cuff up high enough, how would this affect your reading?
    this would give you a falsely low BP
  52. If the BP cuff is too small, how would this affect your reading?
    Too large?
    • Too small - false high
    • Too large - false low
  53. Errors when taking BP
    • Cuff size
    • Arm position
    • Cuff too loose
    • Deflated too quickly
    • Not inflated enough
    • 15 seconds not waited between measurements
  54. Paradoxical pulse
    • A difference in the systolic BP while during inspiration v. expiration

  55. You find your client has a 15 mm diiference in Systolic BP during inspiration v. expiration. What could this signify?
    • This is a paradoxical pulse
    • Often indicative of a serious condition (cardiac tamponade, constrictive pericarditis, emphysema)
  56. Orthostatic hypotension
    • A significant drop in BP when position is changed
    • Drop in SBP > 20 mm or increase in pulse rate > 20 bpm when position is changed
  57. What could be a cause of orthostatic hypotension?
    orthostatic hypotension is caused by: peripheral vasodilation without a compensatory increase in CO2

    • May be found with: Hypovolemia (dehydration)
