Answer to Question 1

D
Patients with severe depression benefit more from a combination of drug therapy and psycho-therapy than from either component alone, so this patient should ask the provider about nondrug therapies. Once a drug has been selected for treatment, it must be used for 4 to 8 weeks before its efficacy can be assessed. Until a drug has been used at least 1 month without success, it should not be considered a failure. Adding a second medication, changing to a different medication, and increasing the dose of this medication should all be reserved until the current drug is deemed to have failed after at least 4 weeks.

Answer to Question 2

B
When tolerance develops, a dose increase may be needed, because a decreased response may occur with prolonged use. Psychologic dependence involves cravings for drug effects and does not define tolerance. Physical dependence occurs when the drug becomes necessary for the brain to function normally, meaning the patient should be weaned from the drug slowly to prevent an abstinence syndrome. Patients may have a decreased sensitivity to drug side effects over time as the brain adapts to the medication.
