|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔Only if needed for angina or hypertension and if
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



EF is preserved. May use amlodipine or felodipine
|\ |\ |\ |\ |\ |\ |\




Common ACEI medications - CORRECT ANSWERS ✔✔Benazapril,
|\ |\ |\ |\ |\ |\ |\



Captopril, Enalapril, Lisinopril, Quinapril, Ramipril |\ |\ |\ |\




Uses of ACEIs - CORRECT ANSWERS ✔✔HPTN, CHF, Proteinuria, Diabetic
|\ |\ |\ |\ |\ |\ |\ |\ |\



nephropathy, prevent unfavorable heart remodeling as result of chronic
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



HPTN



MOA of ACEIs - CORRECT ANSWERS ✔✔ACEIs inhibit ACE which
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



converts Angiotensin I to Angiotensin II. This prevents the actions of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



Angiotensin II which are vasoconstriction and Na2+ and H2O rentention.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



ACEIs also inhibit the breakdown of bradykinin. Bradykinin causes
|\ |\ |\ |\ |\ |\ |\ |\ |\



vasodilation which leaded to reduced SVR and increased CO. |\ |\ |\ |\ |\ |\ |\ |\

, Side effects of ACEIs - CORRECT ANSWERS ✔✔Cough, angioedema, fetal
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



renal malformations, increased GFR and creatinine, hyperkalemia, and
|\ |\ |\ |\ |\ |\ |\ |\



hypotension



ACEIs are contraindicated in - CORRECT ANSWERS ✔✔bilateral renal
|\ |\ |\ |\ |\ |\ |\ |\ |\



artery stenosis and C1 esterase inhibitor deficiency
|\ |\ |\ |\ |\ |\




ACEIs are ____ effective in AAs and they have a(n) _____ risk for
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



angioedema - CORRECT ANSWERS ✔✔less, increased |\ |\ |\ |\ |\




If an ACEIs is not tolerated/contraindicated give - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



✔✔ARBs



Which antihypertensives are contraindicated in patients which asthma or
|\ |\ |\ |\ |\ |\ |\ |\ |\



COPD? - CORRECT ANSWERS ✔✔non-selective beta blockers can cause
|\ |\ |\ |\ |\ |\ |\ |\ |\



bronchospam. They include propranolol, pindolol, nadolol, sotalol, timolol, |\ |\ |\ |\ |\ |\ |\ |\



carvidelol, and labetalol. |\ |\




MOA of digoxin - CORRECT ANSWERS ✔✔Digoxin slows down the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



Na2+/K+ ATPase pump. Na2+ builds up in cell and then leaves via the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



Na2+/Ca2+ exchange instead. Ca2+ then builds up in the cell, leading to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



increased inotrophy (contractility). Increased contractility results in increased
|\ |\ |\ |\ |\ |\ |\



cardiac output and slight diuresis. Digoxin also increased the activity of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



vagus nerve, leading to decreased heart rate d/t decreased conduction
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



through the AV node. |\ |\ |\
