Chapter 20: Nitric oxide & related mediators MULTIPLE CHOICE

1)The effects exerted by nitric oxide include

1. stimulation of platelet aggregation
2. vasoconstriction
3. inhibition of smooth muscle proliferation
4. increased atherogenesis
5. inhibition of host defenses

2.    The primary action of inhaled nitric oxide is

1. vasoconstriction
2. pulmonary vasodilation
3. bronchoconstriction
4. cardiac stimulation
5. respiratory distress

3.    Nitric oxide causes vasodilation by

1. decreasing formation of cyclic GMP
2. increasing formation of cyclic GMP
3. decreasing formation of cyclic AMP
4. increasing formation of cyclic AMP
5. increasing calcium influx

4.    In the gastrointestinal tract, nitric oxide serves to

1. inhibit gastric emptying
2. stimulate gastric emptying
3. inhibit peristalsis
4. inhibit gastric acid formation
5. cause constipation

5.    Nitroprusside produces its effects by acting as

1. a nitric oxide donor
2. a substrate for nitric oxide synthase
3. an inducer of nitric oxide synthase
4. an inhibitor of nitric oxide degradation
5. an agonist at nitric oxide receptors
