Answer to Question 1

B
The sodium pump is the mechanism by which sodium and potassium are moved into or out of cells regardless of the concentration.

Answer to Question 2

B
Such intramuscular (IM) injections must not exceed 2 mL at each site, and the sites of injection should be rotated to allow for proper absorption and to minimize the hazards of local inflamma-tion. When administering an IM iron preparation, it is important to change the needle after drawing up the medication and use a 19- to 20-gauge, 3-inch needle for injection since iron is irritating to the tissues. The Z-track technique for IM injection is recommended.
