How do we plan for nutrition related interventions?
set goals/outcomes. Individualize utilizing assessment data. use "SMART" goals and outcomes
what assessment data do we use to plan for our patients?
factors influencing patient nutritional status. Short and long-term goals (medical and personal)
interventions to promote oral intake?
oral care prior to eating, provide a rest period before meal, patient input on meal planning, position the patient and provide assistive devices, placement of food and orientation to food.
What is enteral nutrition?
providing nutrition through GI tract via NG, jejunal or gastric tubes
