Answer to Question 1

ANS: B
Once a medication is absorbed, it must travel throughout the body via circulating body fluids to their sites of action. This process is called distribution. The bloodstream and lymphatic system usually carry the drug throughout the body. The organs that have the greatest blood supply receive the medication faster, and areas of skin and fat receive the medication more slowly.

Answer to Question 2

ANS: A, B, C
The nurse is responsible for checking that the medication order is correct. This may mean that you need to check the order you have in a medication Kardex and get clarification from the prescriber for any orders that are unclear.
