A nurse is providing teaching about natural food sources that contain folate to a client who plans to become pregnant. The nurse should identify which of the following foods contains the highest amount of folate.

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.

Choice A rationale:
1 cup cooked green peppers. Green peppers are a good source of vitamin C but do not contain a significant amount of folate. Folate is important for preventing neural tube defects in a developing fetus.
Choice B rationale:
1 cup mashed potatoes. While potatoes contain some folate, especially in their skins, they do not have as high an amount as other options. Additionally, mashed potatoes may not retain all of their folate content after cooking and preparation.
Choice C rationale:
1 cup cooked carrots. Carrots are not a substantial source of folate. They are more known for their beta-carotene content, which is converted into vitamin A in the body.
Choice D rationale:
1 cup cooked lentils. Lentils are an excellent source of folate, providing a substantial amount per serving. Folate is essential for preventing neural tube defects in the early stages of pregnancy. Including folate-rich foods like lentils in the diet can be highly beneficial for individuals planning to become pregnant.
