When evaluating a patient who is taking orlistat, which is an intended therapeutic effect?
Decreased weight
Increased appetite
Decreased hyperactivity

The Correct Answer is A
A. Decreased weight: Orlistat is a medication used for weight management by inhibiting the absorption of dietary fats. Its intended therapeutic effect is to promote weight loss by reducing the amount of fat absorbed from the diet.
B. Increased appetite: Orlistat does not increase appetite; rather, it may help control appetite by promoting satiety through its mechanism of action.
C. Decreased hyperactivity: Orlistat is not indicated for the treatment of hyperactivity.
D. Increased wakefulness: Orlistat does not affect wakefulness; it primarily acts in the gastrointestinal tract to inhibit fat absorption.
