**Core Concept**
The base of the umbilical cord is a sensitive area that requires careful monitoring, especially in the first few days after birth. The appearance of the base of the umbilical cord can indicate various conditions, including infection, ischemia, or necrosis.
**Why the Correct Answer is Right**
A red and swollen base of the umbilical cord at 3 days of age is a classic sign of omphalitis, an infection of the umbilical cord stump. This condition can be caused by bacteria such as Staphylococcus aureus, Escherichia coli, or Group B Streptococcus. The infection can lead to the release of inflammatory mediators, causing the cord to become red, swollen, and tender.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because a red and swollen base of the umbilical cord does not typically indicate a normal physiological response to birth or a benign condition.
* **Option B:** This option is incorrect because a blue or pale base of the umbilical cord would indicate ischemia or hypoxia, not a red and swollen appearance.
* **Option C:** This option is incorrect because a white or cheesy appearance of the base of the umbilical cord would indicate a fungal infection, not a bacterial infection.
**Clinical Pearl / High-Yield Fact**
A red and swollen base of the umbilical cord at 3 days of age is a concerning sign that requires prompt evaluation and treatment to prevent the spread of infection.
**Correct Answer: D. Omphalitis**
