A.

Decreased weight

B.

Increased appetite

C.

Decreased hyperactivity

D.

Increased wakefulness

Answer and Explanation

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.

Correct Answer is A

Explanation

A. Carbidopa prevents the breakdown of levodopa in the periphery, specifically in the gastrointestinal tract and peripheral tissues, allowing more levodopa to reach the brain and be converted to dopamine. This enhances the effectiveness of levodopa therapy in managing the symptoms of Parkinson's disease.
B. Carbidopa is not the biologic precursor of dopamine. It is a peripheral decarboxylase inhibitor that does not cross the blood-brain barrier.
C. Carbidopa does not directly allow for larger doses of levodopa to be given. However, by

inhibiting the peripheral breakdown of levodopa, it enhances the availability of levodopa to the central nervous system, potentially improving therapeutic efficacy.
D. While levodopa-carbidopa combination therapy may have fewer drug-food interactions compared to levodopa alone, the primary reason for combining these medications is to enhance the effectiveness of levodopa by preventing its peripheral breakdown.

Correct Answer is B

Explanation

B. A lithium level of 0.9 mEq/L is within the therapeutic range for lithium maintenance therapy, which typically ranges from 0.6 to 1.2 mEq/L. Therefore, it is considered therapeutic.
C. Lithium is commonly monitored with blood levels to ensure therapeutic efficacy and to prevent toxicity.
