Answer to Question 1

A
The Volutrol is filled with the desired amount of IV fluid (50 to 100 mL) by opening the clamp between the Volutrol and the main IV bag. After the Volutrol is filled with the desired amount of fluid, the clamp is closed and the clamp on the air vent of the Volutrol is checked and opened if necessary. The injection port on the Volutrol is cleaned, and the medication is injected through the port.

Answer to Question 2

synergistic effect
A synergistic effect is a drug interaction in which the combined effect of two drugs is greater than the sum of the effects of each individual agent acting independently. In other words, 1+1 = 3 or more. The use of a combination of drugs to treat hypertension is an example of synergism. Each drug lowers blood pressure but in a different way; the summed effect produces a greater reduction in hypertension than is produced by the effects of each medication.
