HNF 471 UNDERSTANDING LAB VALUES IN NUTRITION
ASSESSMENT EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED GRADED A++
Lab values
Measurements used to assess nutritional status.
Nutrition intervention
Strategies to improve a patient's nutritional health.
Trends in lab values
Consistent patterns indicating health changes.
Serum
Liquid part of blood without cells.
Plasma
Fluid component of blood containing proteins.
Hydration status
Body's fluid balance affecting lab results.
Overhydration
Excess fluid diluting lab values.
Dehydration
Fluid deficit causing elevated lab values.
Inflammation
Body's response affecting lab value interpretation.
Basic Metabolic Panel (BMP)
, Tests for Na, K, Cl, CO2, BUN, Creatinine and glucose. Sometimes Ca
Hyponatremia
Low sodium levels, < 135 mEq/L.
Hypernatremia
High sodium levels, > 145 mEq/L.
Hypokalemia
Low potassium levels, < 3.5 mEq/L.
Hyperkalemia
High potassium levels, > 5.0 mEq/L.
BUN
Blood urea nitrogen, reflects kidney function.
Creatinine
Waste product indicating kidney health.
Comprehensive Metabolic Panel (CMP)
Includes BMP (except CO2) plus liver and protein tests, phosphurus, total cholestrol,
liver enzymes, albumin, totial bilirubin, total calcium
Albumin
Protein maintaining oncotic pressure in blood. CMP
Positive acute phase responders
Lab values increase during inflammation.
Negative acute phase responders
Lab values decrease during inflammation.
Factitious hyponatremia
