Question 1

For maximum benefit from the anorectic agent orlistat,the dose should be taken:&#10;A) with three main meals daily.&#10;B) with the morning meal.&#10;C) with the evening meal.&#10;D) at bedtime.

Accepted Answer

Orlistat works by inhibiting the absorption of dietary fat. Therefore, it should be taken with meals containing fat. As most people consume fat with their three main meals of the day, taking orlistat with these meals will provide maximum benefit. Taking it with just the morning or evening meal may not provide adequate fat for orlistat to work effectively. Taking it at bedtime is not recommended as it may interfere with sleep and there may not be adequate fat in the stomach at that time.

Question 2

Which of the following chemical mediators stimulates feeding?&#10;A) Serotonin&#10;B) Noradrenaline&#10;C) Peptide YY&#10;D) Neuropeptide Y

Accepted Answer

Neuropeptide Y is known to stimulate feeding behavior through actions on the hypothalamus, resulting in increased appetite and food intake. Serotonin and peptide YY have been associated with reduced appetite and food intake, while noradrenaline is involved in the fight or flight response and not directly related to feeding behavior.

Question 3

In humans,there are two feeding centres located in the:&#10;A) brain stem.&#10;B) thalamus.&#10;C) hypothalamus.&#10;D) pons.

Accepted Answer

The hypothalamus is responsible for regulating hunger and satiety and contains two feeding centers: the lateral hypothalamus, which stimulates hunger, and the ventromedial hypothalamus, which promotes satiety. The brain stem, thalamus, and pons are involved in other functions such as motor control, sensory processing, and sleep/wake cycles.

Question 4

Which of the following adverse effects would NOT be expected during treatment with a stimulant anorectic?&#10;A) Bradycardia&#10;B) Elevated blood pressure&#10;C) Euphoria&#10;D) Psychological dependence
