reflects the force exerted by the blood in the arteries during heart contraction (systole) and relaxation (diastole)
occurs during ventricular systole of the heart & represents the max. amount of pressure exerted on the arteries
occurs during ventricular diastole of the heart & represents the min. amount of pressure exerted on arteries
what is the normal systolic and diastolic bp?
- systolic <120
- diastolic <80
what is the range for prehypertension?
- systolic 120-139
- diastolic 80-89
what is the range for stage 1 HTN?
- systolic 140-159
- diastolic 90-99
what is the range fpr stage 2 HTN?
- systolic >160
- diastolic >100
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
what could hypotension be the result of?
- fluid depletion
- heart failure
whats pulse pressure?
what is postural (orthostatic) hypotension?
bp falls when a client changes position from lying to sitting or standing
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
name factors that affect bp?
- circadian rhythms
- ethnicity- african americans have higher bp
- gender- males higher bp till women postmenopausal
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
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
