The following medications are used to treat an exacerbation of congestive heart failure.  Each one of them is actually used to counteract mechanisms the body has naturally set in place in response to a drop in blood pressure and presumed drop in tissue perfusion.  For each medication, explain its affect(s) on A, B, and C.  If you feel it has no effect on a particular parameter, then say "no effect".

Specifically for each:

1. A)  affect on TPR (total peripheral resistance) and how/why it changes it


2. B)  affect on cardiac output (contractility, heart rate, stroke volume) and how/why it changes it


3. C)  blood volume/pressure and how/why it changes it


4. ACEIs (ACE inhibitors)


5. Beta blockers


6. Digoxin


7. Nitrates (nitroglycerin, isosorbide)


8. Diuretics like Lasix
