Answer to Question 1

C
Nonpetroleum-based lotion is preferred because it prevents the absorption of latex proteins through the skin, which can cause latex allergy. Both types of lotion help prevent the skin from drying and becoming chafed. Neither prevents microorganisms from adhering to the skin.

Answer to Question 2

B
Trough levels are typically obtained approximately 30 minutes before administering the next dose of the drug. Therefore, the trough cannot be collected with the morning routine laboratory studies. The vancomycin peak should be obtained 2 hours after the next dose infuses. Peak level must be measured when absorption is complete. This depends on all the factors that affect absorption. Trough levels would be inaccurate if the specimen is obtained while the drug infuses.
