Which of the following interventions is crucial when caring for a child receiving intravenous glucose?

Monitoring blood glucose levels is crucial when caring for a child receiving intravenous glucose because this intervention directly addresses the risk of hyperglycemia (high blood sugar) that can occur with the administration of glucose. When children are given intravenous glucose, especially in the context of certain medical conditions or stress responses, their bodies can struggle to regulate blood sugar levels effectively. Regularly checking blood glucose levels ensures that any fluctuations can be identified and managed promptly, preventing complications such as diabetic ketoacidosis or other metabolic imbalances.

The administration of potassium supplements is generally not a routine intervention associated with glucose administration unless there is a specific medical indication for it, such as in the case of certain disorders or electrolyte imbalances. A high-sodium diet is unrelated to the care of a child receiving intravenous glucose, as sodium intake is typically managed based on the child's overall health status and fluid balance rather than the glucose administration itself. Conducting regular blood transfusions is entirely unrelated to the management of intravenous glucose and would be indicated only in specific conditions such as anemia or significant blood loss. Thus, monitoring blood glucose levels is a critical component of care in this context to ensure safety and adjust treatment as needed.
