Choice A rationale Metformin should be taken with meals to help reduce stomach or bowel side effects that may occur during the first few weeks of treatment. Taking it in the afternoon with tea would not align with the prescribed timing. Choice B rationale Waiting 2 hours after eating the evening meal to take metformin is not recommended. Metformin should be taken with meals to help reduce gastrointestinal side effects. Choice C rationale Taking metformin when beginning the evening meal is correct as it helps reduce gastrointestinal side effects and ensures proper absorption. Choice D rationale If the client does not eat an evening meal, they should not wait until bedtime to take metformin. It should be taken with food to minimize gastrointestinal side effects.
