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?

The correct answer is choice c. Omega-3 fatty acids.

Choice A rationale:

Magnesium is generally abundant in a vegan diet, as it is found in many plant-based foods such as nuts, seeds, and leafy green vegetables.

Choice B rationale:

Vitamin A can be obtained from plant sources in the form of beta-carotene, which the body can convert into vitamin A. Therefore, vegans are not at high risk for vitamin A deficiency if they consume a variety of colorful fruits and vegetables.

Choice C rationale:

Omega-3 fatty acids are primarily found in fish and other seafood, which are not part of a vegan diet. While some plant-based sources like flaxseeds, chia seeds, and walnuts provide ALA (a type of omega-3), they may not be sufficient to meet the body’s needs for EPA and DHA, the more active forms of omega-3 fatty acids.

Choice D rationale:

Potassium is readily available in a wide range of fruits and vegetables, such as bananas, potatoes, and spinach, making it unlikely for vegans to be deficient in this nutrient.

Choice A rationale:

Stopping caffeinated beverages is a positive step in managing gastroesophageal reflux disease (GERD) as caffeine can exacerbate symptoms by relaxing the lower esophageal sphincter (LES). However, this choice is not the best-contributing factor to GERD among the options provided.

Choice B rationale:

Correct Choice. Drinking warm milk before bed is a contributing factor to GERD. Milk is slightly acidic and can increase gastric acid production, potentially leading to reflux symptoms. It is important for individuals with GERD to avoid foods or drinks that can relax the LES or increase gastric acid production.

Choice C rationale:

Stopping alcohol consumption is generally beneficial for managing GERD, as alcohol can relax the LES and increase stomach acid production. However, among the choices, this is not the most relevant contributing factor to GERD.

Choice D rationale:

Following a low-fat, high-protein diet is generally recommended for managing weight and promoting overall health. While it is beneficial for weight management, it is not a key contributing factor to GERD symptoms, especially when compared to other choices like drinking warm milk before bed.
