Answer to Question 1

A
Theophylline is a medication that is affected by smoking, which increases serum drug levels. The other factors do not affect the pharmacokinetics of this drug.

Answer to Question 2

D
This folic acid level is very low. Alcohol is known to interfere with the absorption of folate. The nurse should immediately notify the physician. Increasing calories will not in itself increase folate levels. A dietary assessment may be warranted but is not the best response. Sodium is not related.
