What is primary prot/cal malnutrition?
nutritional needs are not met. decreased protein intake and decreased intake of necessary vitamins and minerals.
What is secondary prot/cal malnutrition?
alteration or defect in absorption, digestion, indigestion or metabolism.
What are some things that can lead to secondary prot/cal malnutrition?
GI obstruction, CA, malabsorption issues, drugs, infectious disease
7 nursing diagnoses related to malnutrition?
risk for aspiration, diarrhea, deficient in knowledge, imbalanced nutrition, readiness for enhanced nutrition, feeding self-care deficit, impaired swallowing.
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
When do we begin EN?
an order from the MD and formal type determined by RD. Feedings begin after the xray verifies placement of tube.
