  d. It increases serotonin levels and improves mood.

Question 2

Answer to Question 1

ANS: A
Unlike most other weight-loss drugs, which act in the brain to curb appetite, orlistat acts in the gastrointestinal (GI) tract to reduce absorption of fat.
Orlistat does not act to increase metabolism, suppress appetite, or increase serotonin levels and improve mood.

Answer to Question 2

ANS: B
In reducing fat absorption, orlistat can reduce the absorption of fat-soluble vitamins. To avoid deficiency, patients should take a daily multivitamin supplement 2 hours before or after taking orlistat.
The question does not concern minimization of GI effects, and Metamucil will not accomplish this.
If vitamin-rich foods are eaten at the same time orlistat is taken, the drug would also absorb those nutrients.
Taking a daily multivitamin at the same time as orlistat is not appropriate, because it would not be absorbed.
