While caring for a client receiving total parenteral nutrition (TPN), it is most important for the nurse to monitor which of the client's lab values?

Serum protein.

Serum osmolarity.

Urinary ketones.

Capillary glucose.

Answer and Explanation

The Correct Answer is D

A. Serum protein is an indicator of the client’s overall nutritional status, but it is not as immediately critical to monitor as glucose levels in clients receiving TPN. Protein levels change more slowly over time and are not an acute concern.

B. While serum osmolarity is important in evaluating hydration status and electrolyte balance, it is not the primary lab to monitor during TPN administration. Glucose fluctuations are more likely to cause immediate complications.

C. Urinary ketones are typically monitored in clients with diabetic ketoacidosis (DKA), not in clients receiving TPN. Ketones are a byproduct of fat metabolism and are not a priority in TPN management.

D. Capillary glucose is the most important lab to monitor in clients on TPN because TPN solutions contain high amounts of glucose, which can lead to hyperglycemia. Monitoring glucose levels helps prevent complications such as hyperglycemia or hypoglycemia and is critical in managing the client's metabolic response to TPN.

Correct Answer is D

Explanation

Choice A: Milk products, canned salmon, and fresh oysters are sources of calcium and may be included in the diet but are not primary sources of potassium.

Choice B: Cranberry juice, butter, and hard candy are not significant sources of potassium and may not address the client's hypokalemia.

Choice C: Hard cheese, whole-grain cereals, and dried vegetables are not primary sources of potassium and may not provide an adequate potassium intake.

Choice D: Potatoes, bananas, and oranges are all good dietary sources of potassium and should be encouraged for a client with hypokalemia. Increasing potassium-rich foods can help correct low potassium levels.

A. Salad greens with tomatoes. B. One slice of cheese pizza. C. Roasted turkey sandwich. D. Baked potato with low fat butter

Correct Answer is C

Explanation

Choice A: Salad greens with tomatoes do not provide a significant source of protein.

Choice B: One slice of cheese pizza may contain saturated fats from cheese and processed meats, so it may not be the best choice if the goal is to reduce saturated fat intake.

Choice C: A roasted turkey sandwich can be a good alternative source of protein without the same level of saturated fats found in hamburgers. Turkey is typically leaner than beef, and if prepared without excessive fats or sauces, it can be a healthier choice.

Choice D: Baked potato with low-fat butter is primarily a source of carbohydrates and fats but does not provide a significant source of protein.
