A nurse is teaching a group of parents about appropriate food choices for toddlers. Which of the following choices by the parents demonstrates an understanding of the teaching?

Choice Arationale:
A white blood cell (WBC) count of 5,200/mm3 is within the normal range, which typically varies but is approximately 4,500-11,000/mm3. This result indicates a normal immune response and does not require provider notification.

Choice Brationale:
A hemoglobin (Hgb) level of 14 g/dL falls within the normal range for adults, which is generally between 12-16 g/dL for women and 13.5-17.5 g/dL for men. This result is not a cause for concern, and the nurse does not need to notify the provider about it.

Choice C rationale:
A potassium (K+) level of 3.2 mEq/L is considered hypokalemia. The normal range for potassium is around 3.5-5.0 mEq/L. Hypokalemia can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. The nurse should notify the provider to address this electrolyte imbalance promptly.
Choice D rationale:
A magnesium (Mg) level of 1.6 mEq/L is below the normal range of approximately 1.7-2.2 mEq/L. While mild hypomagnesemia might not require immediate intervention, it's important to monitor and potentially address this electrolyte imbalance, especially if the client's symptoms worsen. However, it does not warrant immediate notification of the provider.

Choice A rationale:
Temperature 38.4°C (101.1°F) An elevated temperature could indicate an infection, which would not be a therapeutic response to total parenteral nutrition (TPN). TPN is provided to support the client's nutrition and help improve their condition; an elevated temperature might suggest ongoing illness.
Choice B rationale:
BMI 18.5 A BMI of 18.5 is considered within the normal range, indicating that the client's malnutrition is improving due to the TPN therapy. A higher BMI suggests a better nutritional status, which is a therapeutic response to the intervention.
Choice C rationale:
BUN 25 mg/dL Blood Urea Nitrogen (BUN) levels can be affected by various factors, including hydration status, renal function, and protein intake. While BUN levels might be monitored to assess renal function and overall nutritional status, a specific BUN level of 25 mg/dL does not directly indicate a therapeutic response to TPN.
Choice D rationale:
Hgb 10 g/dL Hemoglobin (Hgb) level of 10 g/dL is within the normal range for hemoglobin levels. Adequate nutrition, as provided by TPN, can support the production of red blood cells and maintain hemoglobin levels. Therefore, an Hgb level of 10 g/dL can be considered a positive therapeutic response to TPN.
