The flashcards below were created by user ski4me18 on FreezingBlue Flashcards. What would you like to do?


  1. define bp
    reflects the force exerted by the blood in the arteries during heart contraction (systole) and relaxation (diastole)
  2. define systolic
    occurs during ventricular systole of the heart & represents the max. amount of pressure exerted on the arteries
  3. define diastolic
    occurs during ventricular diastole of the heart & represents the min. amount of pressure exerted on arteries
  4. what is the normal systolic and diastolic bp?
    • systolic <120
    • diastolic <80
  5. what is the range for prehypertension?
    • systolic 120-139
    • diastolic 80-89
  6. what is the range for stage 1 HTN?
    • systolic 140-159
    • diastolic 90-99
  7. what is the range fpr stage 2 HTN?
    • systolic >160
    • diastolic >100
  8. For a client to be diagnosed w/ hypertension what has to happen?
    They have to have 2 consecutive BP at the hypertensive range 2 different consecutive visits
  9. what could hypotension be the result of?
    • fluid depletion
    • heart failure
    • vasodilation
  10. whats pulse pressure?
    systolic-diastolic readings
  11. what is postural (orthostatic) hypotension?
    bp falls when a client changes position from lying to sitting or standing
  12. how does one assess someone with orthostatic hypotension?
    • take bp & hr lying down
    • take bp in sitting or stand position
    • wait 1-5 mins & reassess
    • = orthostatic hypotension if systolic blood pressure decreases more than 20 mm Hg or the diastolic bp decrease more than 10 mm Hg w/ 10-20% increase in HR
  13. name factors that affect bp?
    • age
    • circadian rhythms
    • stress
    • ethnicity- african americans have higher bp
    • gender- males higher bp till women postmenopausal
    • medications
    • exercise
  14. what kind of lifestyle modifications could you suggest to a client w/ HTN?
    • smoking cessation
    • dietary modification--- DASH (restrict NA, adequate K, Ca & Mg, restrict cholestrol & saturated fats)
    • weight control
    • modification of alcohol intake
    • physical activity
    • stress reduction
  15. which of the following techniques are correct wehn assessing a clients Bp? (select all that apply)
    have client drink a cup of coffee
    make sure the client has been sitting quiety for at least 5 mins
    average 2 or more readings, seperated by at least 2 mins
    keep the room cold to ensure vasoconstriction
    avoid taking bp readings in an arm w/ a running IV
    • make sure the client has been sitting quietly for at least 5 mins
    • average 2 or more readings, seperated by at least 2 mins
    • avoid taking bp readings in arm w/ running IV
