The commonest earliest complication of TV and GJ is
**Core Concept**
The question refers to the commonest earliest complication of Total Parenteral Nutrition (TPN) and Gastrojejunostomy (GJ) tube placement. This involves understanding the potential risks associated with the initiation of parenteral nutrition and the placement of a GJ tube.
**Why the Correct Answer is Right**
The correct answer is related to the development of hyperglycemia due to the rapid infusion of glucose-containing parenteral nutrition solutions. This can occur because the body's insulin response may not be able to keep pace with the glucose load, leading to elevated blood glucose levels. The liver's glycogen stores are depleted, and the body's ability to store glucose as glycogen is limited, making it difficult to manage glucose levels.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not directly relate to the complications of TPN and GJ tube placement. While infections can occur with any invasive medical device, it is not the earliest complication of TPN and GJ.
**Option B:** This option is incorrect because it refers to a complication that can occur with TPN, but it is not the earliest complication. Cholestasis and liver dysfunction can occur with long-term TPN, but they are not the immediate consequences of initiating parenteral nutrition.
**Option C:** This option is incorrect because it refers to a complication that can occur with TPN, but it is not the earliest complication. Electrolyte imbalances can occur with TPN, but they are not the immediate consequence of initiating parenteral nutrition.
**Clinical Pearl / High-Yield Fact**
To manage glucose levels in patients receiving TPN, it is essential to monitor blood glucose levels closely and adjust the glucose infusion rate accordingly. This can help prevent hyperglycemia and its associated complications.
**Correct Answer:** C. Hyperglycemia
