Answer to Question 1

Correct Answer: 1

Dobutamine (Dobutrex) is a medication that mimics the fight-or-flight response of the sympathetic nervous system. The physiologic effect is improved perfusion and oxygenation of the heart, with increased stroke volume and heart rate, and increased cardiac output. Increased cardiac output, in turn, increases tissue perfusion and oxygenation. This medication will not reduce the heart rate, respiratory rate, or blood pressure.

Answer to Question 2

Correct Answer: 1

Intravenous nitroglycerin must be mixed in glass bottles and infused through special, non-PVC tubing, because up to 4080 of nitroglycerin can be absorbed by PVC bags or tubing. This medication must be infused with an infusion pump and used within 4 hours of reconstitution. The patient receiving intravenous nitroglycerin should be on bed rest, not assisted out of bed.
