Question
Answer
show Amount of blood returning to Right Heart. Lower preload = lower work load for Right Heart. Higher = higher work load  
🗑
Afterload   show
🗑
Hypertension adversely alters what? Can result in?   show
🗑
show Sympathetic(Epi, NE, and Dopa) Blocker = Lowers BP. Anti-hypertensive  
🗑
show given PO, act by interfering with angiotension II(strong vasoconstrictor)resulting in Lower BP. Anti-hypertensive  
🗑
Vasotec   show
🗑
Thiazides   show
🗑
show light sensitive, fast acting , rescue med for acute rise in BP. Given IV drip and require close monitor. Anti-hypertensive  
🗑
show Reduces = lower BP  
🗑
show Drops preload AND afterload in tx of Left sided heart failure(MI). Relaxes smooth muscle surrounding blood vessels = Lower BP and hypotension. Anti-hypertensive  
🗑
show Morphine sulfate, ACE inhibitors, Inderal, Nipride, Thiazides, Vasotec or M.A.I.N.T.V.  
🗑
Vasopressors   show
🗑
show Lack of prefusion = death as absence of O2 and build up of acids take toll on cellular function  
🗑
show sympathomimetic to tx hypotension. In low dose promotes renal vasodilation and diuresis. In high doses stimulates Alpha1 receptors = vasoconstriction. Vasopressor  
🗑
Levophed (norepinephrine)   show
🗑
show Heart failure (MI), by acting as a cardiac stimulant in moderate doses. Beta1 agonist promoting + inotropic and chronotropic.  
🗑
show promote availibility of free Ca+ within myocardium = improved stroke volume. Vasopressor  
🗑
Digitalis, Lanoxin, and Digitoxin   show
🗑
show caused by high levels of digitalis or decrease tolerance. Pts with decrease tol. may have normal levels. Cause from single exposure or chronic overmed. Risks = taking w/quinidine, verapamil, amiodarone. MI commonly given diuretics w/digoxin. Diuretics cau  
🗑
show sympathomimietic w/good Beta1 agonist effects to tx heart failure by improving stroke volume and vasodilation = lower workload on heart

🗑
Calan (verapamil)   show
🗑
show Tx of Premature Ventricular Contractions(PVCs) and othe ventticular arrythmias. Action by reducing sodium influx. Increases resting potential slowing nerve impulse conduction. Higher dose = production of Methemoglobin and seizure. Met reduces availability  
🗑
Inderal ( propranolo)   show
🗑
