When a patient receiving tube feedings asks about the need for insulin, what is the correct response from the nurse?

The correct response emphasizes the fact that tube feedings can indeed lead to temporary hyperglycemia in some patients. This phenomenon occurs because tube feedings generally contain a concentrated source of nutrients, including carbohydrates, which can elevate blood glucose levels. Even in individuals without diabetes, this could result in transient spikes in their blood sugar levels.

Patients receiving tube feedings, especially those with other underlying health issues, may require monitoring of their blood glucose to manage these fluctuations appropriately. The need for insulin would be specifically tied to how the individual patient responds to the tube feedings, rather than a blanket requirement for all patients receiving such nutrition support.

The other options do not accurately address the relationship between tube feedings and insulin requirements. The assertion that insulin is necessary for all patients receiving tube feedings overlooks the individualized nature of care. Claiming that insulin is given to prevent infection during tube feedings misrepresents the purpose of insulin, as it is primarily concerned with glucose metabolism, not infection control. Lastly, stating that insulin is administered solely based on a doctor's order fails to acknowledge the importance of assessing the patient's specific needs and responses to nutrition.
