Final answer:
The correct statement indicating understanding of orlistat use is to stop taking it and call a doctor if urine darkens. Orlistat blocks fat absorption and should be taken with meals, not on a no-fat diet. It doesn't affect hunger.
Therefore, option is correct.(c)
Step-by-step explanation:
A client who has been prescribed orlistat for binge-eating disorder and is morbidly obese understands the teaching if they say, "I will stop taking orlistat and call my doctor if my urine gets darker in color." Orlistat works by inhibiting the absorption of dietary fats, which can lead to fat-soluble vitamins and other substances being excreted in the stool. Dark urine could indicate a liver problem, one of the serious side effects of orlistat, and therefore necessitates immediate medical attention. Orlistat should be taken with meals containing fat (up to three times per day), not just once in the morning, and it is important to follow a reduced-calorie, low-fat diet, but not a no-fat diet since some fat is needed for orlistat to work. Finally, orlistat does not directly affect hunger or satiety during meals.
