Monitoring Nutritional Improvement in a Client with Anorexia: Evaluating Laboratory Findings

QUESTION

The nurse is caring for a client who has anorexia and is severely malnourished. A nasogastric (NG) feeding tube is inserted, and tube feedings are started. Which of the following laboratory findings is the best indication that the client’s nutritional status is improving? Sodium has increased from 130 to 144 mg/dL. Creatinine has dropped from 1.9 to 0.5 mg/dL. Albumin level has increased from 2.5 to 4 g/dL. Blood urea nitrogen (BUN) level has dropped from 15 to 11 mg/dL.

ANSWER

Monitoring Nutritional Improvement in a Client with Anorexia: Evaluating Laboratory Findings

Introduction

Caring for a client with anorexia and severe malnutrition requires close monitoring of their nutritional status and overall health. The effectiveness of interventions, including nasogastric (NG) tube feedings, can be assessed through laboratory findings that reflect improvements in various physiological parameters. This essay examines the provided laboratory findings and identifies the best indication of the client’s nutritional status improvement.

Evaluating Laboratory Findings

Sodium Increase from 130 to 144 mg/dL

While sodium levels can fluctuate due to multiple factors, an increase in sodium levels from 130 to 144 mg/dL does not necessarily directly reflect nutritional status improvement. Sodium levels can be influenced by hydration status and other factors, making it a less reliable indicator of nutritional improvement in this context.

Creatinine Drop from 1.9 to 0.5 mg/dL

Creatinine is a waste product that reflects kidney function and muscle mass. A significant drop in creatinine from 1.9 to 0.5 mg/dL suggests improved kidney function, potentially due to enhanced nutritional intake. However, creatinine is not a direct marker of nutritional status but rather an indicator of overall health and renal function.

Albumin Level Increase from 2.5 to 4 g/dL

Albumin is a protein synthesized in the liver that reflects long-term nutritional status. An increase in albumin level from 2.5 to 4 g/dL is a strong indicator of improved nutritional status. Albumin levels rise slowly, making it a reliable marker of long-term changes in nutritional intake and absorption.

Blood Urea Nitrogen (BUN) Level Drop from 15 to 11 mg/dL

BUN is a marker of kidney function and protein breakdown. A decrease in BUN level from 15 to 11 mg/dL suggests improved kidney function and potentially decreased protein breakdown. While this change is positive, BUN is not a direct marker of nutritional status improvement.

Conclusion

Among the provided laboratory findings, the increase in albumin level from 2.5 to 4 g/dL is the best indication that the client’s nutritional status is improving. Albumin reflects long-term nutritional intake and synthesis, making it a reliable marker of overall nutritional status. While other laboratory findings may indicate improvements in kidney function and overall health, albumin stands out as the most relevant marker of the client’s nutritional improvement in the context of severe malnutrition and NG tube feedings.
