Which task cannot be performed by a caregiver under nurse delegation?

Injecting medications other than insulin typically falls outside the scope of tasks that can be delegated to caregivers under nurse delegation policies. Nurse delegation allows registered nurses to assign certain basic healthcare tasks to trained caregivers, but there are specific limitations regarding medications. The administration of injections, especially those that are not routine like insulin, generally requires a higher level of oversight and training, as it involves understanding potential reactions, dosage calculations, and the complexities of various medications.

In contrast, tube feedings, colostomy care, and assisting with daily living activities are often within the scope of nurse delegation. These tasks are more aligned with the day-to-day care that caregivers provide and typically don't involve the same level of risk or complexity associated with medication administration. Thus, while caregivers play a crucial role in supporting patients, certain high-stakes medical interventions remain strictly within the nursing domain to ensure safety and proper care.
