TERM 1 Creatinine Height index DEFINITION 1 somatic protein assessmentLower the number the more severe malnutrition. Normal is considered 1 Creatine phosphate stored in muscle, creatinine is not stored in muscle but is cleared and excreted by the kidney Limitations =Depends on a complete collection of urine for 24 hours, therefore it is difficult to conduct Does not account for age, disease, physical training, frame size, or weight status TERM 2 Nitrogen balance DEFINITION 2 somatic protein assessmentNitrogen excretion should = nitrogen intakenegative nitrogen balance (excretion > intake) Indicates catabolism, inadequate nitrogen intake, malnutritionpositive nitrogen balance (intake > excretion) indicates anabolismnot routinely used for acute-care patients, more common in critical carelimitations 24hr urine collection error, failure to account for renal impairment,inability to measure nitrogen loss from wounds, burns, diarrhea, and vomiting TERM 3 albumin DEFINITION 3 visceral protein assessmentnormal levels = 3.5-5.0 g/dLFunction: blood transport proteinHalf life: 17-21 daysLimitations Long half life Affected by inflammation, stress or trauma Hydration status (higher levels with dehydration) TERM 4 Transferrin DEFINITION 4 visceral protein assessmentNormal levels are 215-380 mg/dL Function: iron transport, indicator of protein throughout body (bc short half life)Half life: 8-10 daysLimitations (affected by) Iron status Diseases: hepatic and renal disease, inflammation, and congestive heart failure TERM 5 prealbumin/transythretin DEFINITION 5 visceral protein assessmentNormal = 19-43 mg/dLFunction: transport of thyroxine and associated with RBPHalf life: 2-3 days (respond to short term modifications in nutritional intake)Affected by Decreases with illness, inflammation, stress or trauma Liver disease, malabsorption, hyperthroidism TERM 6 Retinal binding protein (RBP) DEFINITION 6 visceral protein assessment Normal 2.1-6.4 mg/dLFunction: transport protein for Vitamin AHalf life: 10-12 hoursAffected by many conditions: Elevated with renal failure Decreased w/hyperthyroidism, Cystic Fibrosis, liver failure, Vitamin A deficiency and metabolic stress. TERM 7 mean corpuscular volume (MCV) DEFINITION 7 hematologicalAnemia measure by changes in red blood cell sizeReduced in iron and copper deficienciesElevated in folic acid and vitamin B12 deficiencies TERM 8 mean corpuscular hemoglobin DEFINITION 8 hematologicalamount of hemoglobin per cellAffected by iron deficiency and other nutritional anemias TERM 9 skin DEFINITION 9 protein, vitamin c, zincfatty acids, vitamin aniacinVitamin kdehydration TERM 10 nails DEFINITION 10 ironproteinvitamin a or ccalories TERM 21 cardiac system DEFINITION 21 thiamin TERM 22 gastrointestinal system DEFINITION 22 protein, calories, zinc, vitamin c TERM 23 urinary tract DEFINITION 23 hydration status TERM 24 musculoskeletal system DEFINITION 24 vitamin d, calciumproteinvitamin cthiamin TERM 25 nervous system DEFINITION 25 proteinthiamin, B6niacin, vitamin B12calcium, magnesium
