**Core Concept**
Newborns undergo a series of physiological changes and adaptations at birth, including respiratory, cardiovascular, and renal adjustments. These changes are crucial for the transition from a fetal to an adult-like state.

**Why the Correct Answer is Right**
The correct answer will be a finding that is not typical or expected in a healthy newborn. Newborns may exhibit various normal physiological changes, such as grunting, nasal flaring, and tachypnea, due to the sudden change in oxygenation and ventilation at birth. However, certain findings may indicate underlying pathology or complications.

**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect because newborns often experience some degree of respiratory distress due to the transition from the fetal to the adult respiratory system.

**Option B:**
This option is incorrect because newborns may exhibit some degree of jaundice, which is a common and usually benign condition.

**Option C:**
This option is incorrect because newborns may experience some degree of hypoglycemia, which can be due to the sudden drop in glucose levels after birth.

**Option D:**
This option is incorrect because newborns may experience some degree of bradycardia, which can be a normal response to the stress of birth.

**Clinical Pearl / High-Yield Fact**
Newborns are at risk for hypoglycemia due to the sudden drop in glucose levels after birth, especially if they are premature or have a low birth weight. This can be prevented with early feeding and monitoring of glucose levels.

**Correct Answer: D. Bradycardia**
