A nurse is reviewing a client's laboratory results for the effectiveness of total parenteral nutrition (TPN). Which of the following laboratory values is the best indicator for the nurse to monitor for the short-term effectiveness of the TPN?

Choice A rationale:
Crohn's disease is not commonly associated with obesity. Crohn's disease is a chronic inflammatory bowel disease that can lead to weight loss due to malabsorption and other gastrointestinal symptoms.
Choice B rationale:
Peptic ulcer disease is not directly linked to obesity. Peptic ulcers are primarily caused by Helicobacter pylori infection or the use of nonsteroidal anti-inflammatory drugs (NSAIDs).
Choice C rationale:
Gastroesophageal reflux disease (GERD) is commonly associated with obesity. Excess weight, especially around the abdominal area, can contribute to increased pressure on the stomach and lower esophageal sphincter, leading to the backflow of stomach acid into the esophagus and causing symptoms of GERD such as heartburn and regurgitation.
Choice D rationale:
Celiac disease is not typically associated with obesity. Celiac disease is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. Individuals with celiac disease often experience weight loss and malabsorption due to intestinal damage.

Choice A rationale:
Citrus fruits. Citrus fruits are generally not associated with high allergy risk, especially in comparison to some other allergenic foods. While any food has the potential to cause an allergic reaction, citrus fruits are less likely to be a significant concern for toddlers in terms of allergies. They are rich in vitamin C and are generally considered healthy choices for most individuals.
Choice B rationale:
Bananas. Bananas are also not commonly associated with high allergenicity. They are typically well-tolerated by most individuals and are often recommended as an early solid food for infants. The risk of allergies to bananas is relatively low, making them a safe choice for toddlers.
Choice C rationale:
Milk. While milk allergies are more common in infants and young children, they tend to decrease with age. Additionally, the question refers to toddlers, who are past the age where milk is typically introduced. While milk allergies can occur, they are not usually the highest risk for allergies in toddlers.
Choice D rationale:
Eggs. Eggs are known to be one of the top allergenic foods, especially in young children. They can trigger severe allergic reactions, including anaphylaxis, in susceptible individuals. The protein in egg whites is often responsible for these reactions. Because of the high allergy risk associated with eggs, they are the highest concern among the options listed for allergies in toddlers.
