**Core Concept**
The management of a large for gestational age baby with hypoglycemia (blood sugar of 35 mg/dl) involves understanding the pathophysiology of neonatal hypoglycemia and the role of glucagon in glucose metabolism.

**Why the Correct Answer is Right**
Neonatal hypoglycemia is a common issue in large for gestational age babies due to the transient adaptation to the intrauterine environment, leading to impaired glucose production and increased glucose utilization. Glucagon, a hormone produced by the pancreas, plays a crucial role in stimulating glycogenolysis and gluconeogenesis to maintain blood glucose levels. In the setting of neonatal hypoglycemia, glucagon therapy is often employed to rapidly increase blood glucose levels.

**Why Each Wrong Option is Incorrect**
**Option A:** This option might be incorrect if the management plan does not address the underlying cause of hypoglycemia, such as impaired glucose production or increased glucose utilization. Without addressing the root cause, glucagon therapy may not be effective in preventing future episodes of hypoglycemia.
**Option B:** This option may be incorrect if it involves the administration of glucose without addressing the underlying pathophysiology of neonatal hypoglycemia. Glucose therapy may provide temporary relief but does not address the underlying issue of impaired glucose production or increased glucose utilization.
**Option C:** This option might be incorrect if it does not involve the administration of glucagon, which is a critical component of managing neonatal hypoglycemia.

**Clinical Pearl / High-Yield Fact**
In neonates, hypoglycemia can lead to serious complications, including seizures, brain damage, and even death. Early recognition and management of neonatal hypoglycemia are crucial to prevent these complications.

**Correct Answer:** C. Administer glucagon to rapidly increase blood glucose levels.
