## **Core Concept**
The core concept being tested here is the normal hemoglobin level in newborns. Hemoglobin is a crucial protein in red blood cells that carries oxygen throughout the body. Newborns have different hemoglobin levels compared to adults due to the physiological changes that occur at birth.

## **Why the Correct Answer is Right**
Newborns typically have higher hemoglobin levels than adults, which is essential for adapting to the extrauterine environment. The normal hemoglobin range for newborns is approximately 16 to 20 g/dL, with an average of around 18 g/dL. This higher level helps to ensure that the newborn's tissues receive adequate oxygen.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 10-12 g/dL is lower than the expected range for newborns and is more in line with normal hemoglobin levels for adult women.
- **Option B:** 12-14 g/dL is still lower than the typical range for newborns and could be considered within the normal range for adult men but not for newborns.
- **Option D:** 25-30 g/dL is higher than the normal range for newborns and would not be considered a standard value for this population.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that newborns have a higher hemoglobin level than adults, with a normal range of approximately 16 to 20 g/dL. This knowledge is crucial for pediatric healthcare providers to assess the health status of newborns accurately.

## **Correct Answer:** C. 16-20 g/dL.
