Exam 2 shortened Flashcards
(151 cards)
primary HTN
no known cause
associated with risk factors
secondary HTN
specific disease states
medications such as estrogen, steroids, immunosuppressants
malignant HTN
severe with rapid progression
individuals 30-50 years old
pulmonary HTN
vasoconstriction
increased vascular resistance
poor tissue perfusion
right sided HF
hypoxemia
rebound HTN
abrupt d/c of meds
white coat HTN
in clinical setting
isolated systolic HTN
elderly
structural and functional change associated with age
decrease in elasticity of everything including blood vessels
not able to handle blood, increased stroke volume
cerebrovascular morbidity and mortality
normal BP
systolic <120
AND
diastolic <60
elevated BP (pre HTN)
systolic: 120-129
AND
diastolic: <80
stage 1 HTN
systolic: 130-139
OR
diastolic 80-89
stage 2 HTN
systolic: >140
OR
diastolic >90
hypertensive urgency (BP, organ damage, treatment)
very high BP
no organ damage
fast acting agents (ACE, BB)
normalize BP within 24-48 hours
hypertensive emergency (BP, organ damage, med, treatment)
BP >180/120
organ damage
IV vasodilators
reduce BP by 25% within one hour
gradual reduction over 6 hours
not too fast, can cause organ failure from sudden decrease in perfusion
signs and symptoms of PVD
claudication of the foot arch, hands, and/or lower limbs
pain may occur at rest
increased sensitivity to cold with numbness
diminished distal pulses
cool extremities
nursing care for PVD
monitor every 15, 30, 60 minutes
assess extremity and compare:
-pulse
-BP
-infection
-bleeding
limited ROM with bed rest for 24 hours
avoid crossing legs, standing still, trauma to extremities, constriction
wear closed toe shoes and white socks
night light and skid-free rugs
no smoking
legs lower than heart
avoid cold temps
arterial vs venous pain
arterial: claudication, numbness, and tingling
venous: feeling of fullness with prolonged standing or sitting
arterial vs venous pulse
arterial: decreased or absent bilaterally
venous: difficult to find or full
arterial vs venous color
arterial: pale, elevated leg; dusky/red, dependent leg
venous: cyanotic on dependency
arterial vs venous temperature
arterial: cool
venous: warm
arterial vs venous edema
arterial: absent or mild
venous: present
arterial vs venous skin
arterial: dry
venous: moist
arterial vs venous ulcers
arterial: toes and gangrene
venous: superficial with gangrene
raynaud’s
vasospasms of hands/feet
affects 17-50 years old
more common in women
worse in cold and stress
connective tissue, autoimmune disorder
blanching/cyanosis
numbness
throbbing pain
raynaud’s treatment
calcium channel or adrenergic blockers
sympathectomy
decrease cold temp
no smoking
wear gloves
avoid drugs that increase vasospasm (OTC decongestants)
