- 14.For the treatment of MI, one of these drugs decreases heart rate by the sympathetic nervous system and prevents the development of angina pectoris. Reduces cardiac output by blocking beta and epinephrine.

Calcium Channel blockers
- B.
Beta Adrenergic blockers
- C.
Nitroglycerin
- D.
Morphine sulfate
- E.
IV drug
- 15.For the treatment of MI, one of these drugs decreases the heart workload by dilating blood vessels, increasing cardiac oxygen demand in stable angina. Alleviates chest pain by improving blood flow.
- A.
Calcium Channel blockers
- B.
Beta Adrenergic blockers
- C.
Nitroglycerin
- D.
Morphine sulfate
- E.
IV drug
- 16.What's the name of a non-selective beta-blocker that blocks both beta 1 and 2 receptors, reduces force of contraction and heart rate- used to treat tachycardia, hypertension and prevent MI?
- 17.For the treatment of MI, which one of these drugs FALLS UNDER THE CATEGORY that relies on the principle that calcium needs to move from extracellular space into intracellular space to create cardiac contractions. This type of drug blocks the calcium channels that are especially concentrated in the SA node and AV node this effect and smooth the cardiac muscles, causing dilation of the blood vessels. Used to treat angina and lower BP.
- A.
Inderal
- B.
Propranolol
- C.
Verapamil ( calan, isoptin)
- D.
Phenytoin
- E.
Lidocaine
- 18.For the treatment of MI, one of these drugs slows down the conduction of the AV node and causes depression of the myocardial contractility and causes dilation of coronary arteries. Also, the side effects include dizziness, sleepiness, headache, peripheral edema, hypotension, nausea, constipation.
- A.
Inderal
- B.
Propranolol
- C.
Verapamil ( calan, isoptin)
- D.
