Nursing Priority Diagnosis
"Imbalanced nutrition: less than body requirements related to decreased desire to eat secondary to Anorexia, nausea and vomiting" (Carpenito, 2013, p. 449).

"Intake of nutrients insufficient to meet metabolic needs" (Carpenito, 2013, p. 447).

2. Nutritional history
a. Include family, significant others, or caregiver in assessment
3. Etiological factors for reduced nutritional intake
4. Patient attitude towards eating and food
5. Lab values that indicate nutritional wellbeing or deterioration
a. Serum albumin – indicates degree of protein depletion (2.5 g/dL indicates severe depletion; 3.8 to 4.5 g/dL is normal)
b. Transferin - important for iron transfer and typically decreases as serum decreases
c. Red blood cell and white blood cell counts – usually decreased in malnourished patients; indicates anemia and decreased resistance to infection
d. Serum electrolyte values – potassium is typically increased and sodium is typically decreased in malnutrition
