Pharm hypertension 3 Flashcards
olol are
Bate blockers
propranolol, metoprolol, atenolol, esmolol.
Where do you take the pulse on a Beta 1 blocker
Apical pulse for 1 min
pulse less then 60bpm hold medication
What are the Beta 1 blockers
Adrenergic blockers
propranolol
Beta1- adrenergic blockers: propranolol M.O.A.
Blocks beta1 receptors= decreases heart rate and cardiac contractility lowering cardiac output (BP)
Reduces peripheral vascular resistance.
adverse effects of Beta1 blockers
hypotension. bradycardia, vertigo, syncope.
Avoid Beta1 in ?
Asthmatics
blocks the bate2 receptors in lungs
why should Beta1 blockers be used cautiously in diabetics?
can mask symptoms of hypoglycemia such as tachycardia
What to teach patients when on Beta1 blocker
change position slowly
take with food to increase absorption
What are the Aplha1 blockers?
prazosin (Minipres)
M.O.A. of Alpha blockers
Blocks alpha1- adrenergic receptors on blood vessels
(blockage leads to arteriolar/ venous vasodilation)
Adverse effects with Alpha1 blockers
postural hypotension, vertigo, syncope
Nursing intervention for Alpha1 blockers
teach patient to take first dose at bedtime to minimize hypotension.
Angiotensin- converting enzyme inhibitors also known as
ACE inhibitors
ACE inhibitors
enalapril (Vasotec)
Lisinopril (Zestril)
block the conversion of angiotensin to angiotensin 2 leads to vasodilation, excretion of Na+/H2O, retention of K+.
Often prescribed for antihypertensive effects in the diabetic: helps to minimize the effects of diabetes on the kidneys.
ACE inhibitor
