Section B of a POLST include orders on medical interventions, including use of oxygen, suction, IV fluids, airway support and advanced interventions such as intubation, mechanical ventilation, and other intensive care-related procedures. Section D includes non-emergency treatment decisions including whether the patient should receive antibiotics, medically assisted nutrition and hydration, and dialysis. Some of these POLST orders may indicate medical interventions outside the scope of a nursing assistant. Specific activities may require delegation of certain medical interventions identified in the POLST sections B and D, depending on the task, equipment available, and competency of the nursing assistant.
