Answer to Question 1

B
Solutions are hypertonic, isotonic, or hypotonic. Infusion of isotonic solutions such as 0.9 sodium chloride (a solution of equal osmotic pressure) expand the body's intravascular fluid volume without causing a fluid shift from one compartment to another.

Answer to Question 2

D
Disconnecting the drainage tube from the catheter breaches sterile technique and can cause in-troduction of bacteria into the system. Because urine in the drainage bag can rapidly grow bacte-ria, never take a urine sample from the drainage bag.
