interference with normal appetite or assimilation of nutrients, caused by disease or inadequate diet.

What is over nutrition?

intake of more calories than required for bodily needs

Dysphagia is ___

difficulty swallowing

warning signs of dysphagia?

coughing while eating, voice tone/quality changing after eating, abnormal gag relux, abnormal swallowing triggers

Complications from dysphagia?

aspiration pneumonia (silent aspiration), dehydration, decreased nutrition intake, wt loss

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.

Polymeric EN is _

milk based

"Specifically" EN is __

specific to nutrient needs

Complications with EN? What are risk factors for these complications?

aspiration which can lead to pneumonia. Laying flat, GERD, nasotracheal suctioning, artificial airway, decreased LOC

Interventions with EN to improve the efficiency of EN?

keep HOB elevated at 30-45* at all times, measure gastric residual volumes (GRV) every 4-6 hours or immediately prior to feeding.
