Correct Answer is A

Explanation

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.

A. Minimize the amount of fluid taken while on this drug. B. Discontinue the medication if adverse effects occur. C. Take the medication on an empty stomach to enhance absorption. D. Use artificial saliva, sugarless gum, or hard candy to counteract dry mouth.

Correct Answer is D

Explanation

A. Minimize the amount of fluid taken while on this drug: Increasing fluid intake is actually recommended to manage potential constipation, another common side effect of anticholinergic medications.
B. Discontinue the medication if adverse effects occur: Discontinuing medication without consulting a healthcare provider is not advisable. Patients should be educated to report any adverse effects to their healthcare provider for appropriate management.
C. Take the medication on an empty stomach to enhance absorption: Benztropine is typically taken with food to minimize gastrointestinal side effects. Taking it on an empty stomach may increase the risk of nausea or stomach upset.
D. Use artificial saliva, sugarless gum, or hard candy to counteract dry mouth: Anticholinergic medications such as benztropine commonly cause dry mouth as a side effect. Stimulating saliva production with these measures can help alleviate dry mouth symptoms.
