Final answer:
When teaching a patient about lorcaserin, nurses should instruct that blood glucose levels may need to be monitored more frequently, especially in someone with diabetes. This is because weight loss and the medication can affect how the patient responds to their current diabetes treatment.
Step-by-step explanation:
The most appropriate answer to the student's question about what a nurse should include when teaching a patient about the drug lorcaserin [Belviq] for weight loss is ' You may need to check your blood glucose levels more often.' Lorcaserin is used to help with weight management in conditions such as obesity, often in combination with diet and exercise. However, since the patient also has diabetes, there's a need for careful monitoring of blood glucose levels as the weight loss and the drug itself could alter the patient's response to insulin or other diabetes medications. To ensure safe and effective use of lorcaserin, patients should be advised that they might have to check their blood glucose more frequently to avoid complications such as hypoglycemia or hyperglycemia.
It is not recommended to say that lorcaserin is safe during pregnancy or to guarantee the absence of serious adverse effects without more information. Additionally, there is no upfront recommendation to increase the insulin dose as it would depend on frequent monitoring and the patient's current blood glucose levels.
