  c. liver's inability to metabolize water-soluble drugs.

Answer to Question 1

B
Water-soluble drugs penetrate the bloodbrain barrier slowly and in insignificant amounts. A dose high enough to affect the brain would invariably cause adverse systemic side effects. The other effects are not related.

Answer to Question 2

A
When a patient does not respond to a drug, or when symptoms reappear after a good response to the drug, the nurse should assess for compliance. Is the patient taking the drug? Is the patient taking less of the drug than ordered? The other options are less relevant or of no value.
