Final answer:
A nurse recommends mineral oil as a laxative that should not be taken with meals because it can interfere with nutrient absorption. Mineral oil acts as a lubricant to ease stool passage.
Step-by-step explanation:
When a nurse recommends a laxative that should not be taken with meals, she is likely talking about mineral oil. It is recommended to take mineral oil at least 2 hours before or after meals because it can interfere with the absorption of nutrients from food if taken too closely to meal times. Mineral oil works as a lubricant laxative, helping the stool to pass more easily. On the other hand, other types of laxatives like Dulcolax (a stimulant laxative), Metamucil (a fiber supplement), and Colace (a stool softener) do not have such strict guidelines regarding meal consumption.
