Hypertension Flashcards
What causes Primary Hypertension?
causes unknown
risk factors: genetics, hyperlipidemia, ethnicity, diabetes, obesity, age, stress, smoking, alcohol
What causes Secondary Hypertension?
medications
renal or endocrine cause
What are some HTN related diseases?
Heart failure
MI
CVA
Kidney failure
Retinopathy
Non-Pharmacological Treatments for HTN?
Diet
Exercise
Weight
Quit Tobacco
Decrease alcohol
Stress reduction
What drugs treat HTN?
Diuretics
ACE
Angiotensin 2 Receptor Blockers
Calcium Channel Blockers
Beta-andrenergic antagonists
Alpha 1 adrenergic antagonists
Central acting alpha 2 adrenergic agonists
direct acting vasodilators
How do thiazide diuretics work?
pushing out Na from distal tubule and keeping it out, therefore water follows
What is the name of a thiazide diuretic?
hydrochlorothiazide (HCTZ)
Contraindications for HCTZ?
hypokalemia
anuria (failure to produce urine)
pregnancy and lactation
Side effects of HCTZ?
hypotension
headache
hypokalemia
hyperuricemia (gout attacks)
What do you monitor while on HCTZ?
serum drug levels of other meds (digoxin)
When should you take HCTZ?
MORNING
What is the angiotensin-converting enzyme inhibitor? (ACEIs)
lisinopril
What is the angiotensin 2 receptor blockers? (ARBs)
losartan
What combines to make Angiotensin 1?
Angiotensin and Renin
What combines to make Angiotensin 2?
Angiotensin 1 and ACE
What does Angiotensin 2 do?
Increase in aldosterone production: fluid increases in blood due to reabsorption of Na+
What do ACE inhibitors do?
prevents conversion of angiotensin 1 to angiotensin 2
decrease blood pressure
Most common side effect of lisinopril?
cough
What are contraindications of lisinopril?
women of reproductive age (teratogens)
history of angioedema
african americans
Nursing considerations for lisinopril?
hold if systolic BP <90
monitor potassium and sodium
monitor ambulation
Avoid NSAIDS
MOA of losartan?
blocks angiotensin 2 from acting on target organs and tissues
Contraindications of losartan?
pregnancy and lactation
hypotension
Side effects of losartan?
hypotentions
headache
TERATOGEN
What do calcium channel blockers do?
inhibit calcium ion movement across cardiac and arterial muscle cell membranes
(VASODILATION)
