Exam 2 Hypertension Flashcards
hypertension
high blood pressure
systolic blood pressure
BP when the heart contracts; the top #
diastolic blood pressure
BP when the heart is resting
hypertension levels
systolic: 130+
diastolic: 80+
diuretics MOA
-increases urine flow
-lowers blood pressure by reducing the fluid inside blood vessels
-increase Na+ excretion–> hyponatremia
hyponatremia
low sodium in the blood
high sodium levels
hypernatremia
diuretics indications
hypertension and edema
edema
excess accumulation of fluid in the body
micturition
urination
warnings for diuretics
most diuretics contain sulfa moiety, which should be watched in patients with sulfa allergies
thiazide diuretics
potassium depleting diuretics that excrete potassium, sodium, and water
examples of thiazide diuretics
hydrochlorothiazide, indapamide, chlorthalidone, metolazone
which is the most preferred thiazide diuretic?
chlorthalidone
important patient-counseling for thiazide diuretics
can cause photosensitivity
hypokalemia levels
low levels of potassium in the blood that can cause weakness and leg cramps
loop diuretics
potassium depleting diuretics that can cause hypokalemia
examples of loop diuretics
furosemide, bumetanide, torsemide
furosemide
Lasix
bumetanide
Bumex
warnings for loop diuretics
electrolyte depletion and dehydration if given in excessive amounts
when should loop diuretics be taken?
in the morning
potassium sparing diuretics MOA
-does not excrete potassium in urine
-increase K+ level
examples of potassium sparing diuretics
spironolactone, eplerenone, triamterene
