1. True
2. False
Nitroglycerin preparation(s) presently available include(s):
1. Isosorbide dinitrate
2. Isosorbide-5-mononitrate
3. Nitroglycerin
4. C only
5. A, B & C
Nitroglycerin administration changes in myosin light chain phosphorylation state.
1. True
2. False
Nitric oxide (NO) was previously known as endothelium-derived relaxing factor.
1. True
2. False
Pharmacological action(s) of nitroglycerin administration include(s):
1. Preferential venular versus arteriolar dilation
2. Venodilation associated with nitroglycerin administration paradoxically increases venous return thus elevating right and left ventricular chamber size.
3. Following nitroglycerin administration end-diastolic pressures tend to increase slightly without much change in systemic vascular resistance.
4. A&B
5. A&C
6. A,B & C
One of the advantages of using organic nitrates in treating vascular ischemia is their ability to "recruit" coronary collaterals.
1. True
2. False
Which one(s) of the following statements is/are correct concerning organic nitrate pharmacology?
1. Nitroglycerin exhibits anti-thrombotic effects.
2. Nitroglycerin (nitrates generally) likely reduces the frequency of angina.
3. Nitroglycerin administration increases the time required to identify ischemic ECG changes during treadmill testing.
4. Nitrate monotherapy does not affect survival or reduce cardiovascular death frequency in chronic coronary artery disease patients.
5. B & C
6. A,B & C
7. A,B,C & D
Tachyphylaxis to nitrate use is sufficiently common in clinical settings to warrant consideration of a nitrate-free time period, perhaps from 8-12 h to 2-3 days.
1. True
2. False
In smooth muscle, nitrate administration tends to slightly increase cytosolic calcium concentration.
1. True
2. False
