**Core Concept**
In pediatrics, intravenous (IV) nutrition is crucial for children who are unable to feed orally. However, IV nutrition can lead to various complications, including metabolic disturbances.

**Why the Correct Answer is Right**
When a child is given IV nutrition, the body's metabolic response is altered. The lack of enteral nutrition can lead to a decrease in the production of bile salts, which in turn can cause a shift in the balance of glucose and lactate metabolism. This can result in **hyperglycemia** due to the administration of glucose-containing IV fluids. Furthermore, the absence of enteral nutrition can also lead to **metabolic acidosis** due to the increased production of lactic acid. Additionally, IV nutrition can increase the risk of **infection**, particularly if the IV line becomes contaminated or if the child has a compromised immune system.

**Why Each Wrong Option is Incorrect**
**Option A:** Infection is a potential complication of IV nutrition, but it is not the only one. The question asks which of the following can occur, and all options are correct.
**Option B:** While hyperglycemia can occur with IV nutrition, it is not the only metabolic disturbance that can occur. The question is asking for a comprehensive answer.
**Option C:** Metabolic acidosis can occur with IV nutrition, but stating it as the only option is incorrect. The question asks which of the following can occur, and all options are correct.

**Clinical Pearl / High-Yield Fact**
It is essential to monitor glucose and electrolyte levels closely in children receiving IV nutrition to prevent metabolic disturbances. Additionally, ensuring proper sterile technique when inserting IV lines can help prevent infection.

**✓ Correct Answer: D. All of these**
