## **Core Concept**
Neonatal meningitis is a serious infection that occurs in newborns, typically within the first month of life. It is often caused by bacteria, with Group B Streptococcus (GBS) and Escherichia coli (E. coli) being the most common pathogens. The presentation of neonatal meningitis can be subtle and nonspecific.

## **Why the Correct Answer is Right**
The correct answer, **seizures and vomiting**, reflects the common clinical manifestations of neonatal meningitis. Newborns with meningitis may exhibit nonspecific symptoms such as lethargy, irritability, feeding difficulties, and temperature instability. However, more specific signs like seizures and vomiting are indicative of central nervous system involvement. Seizures are particularly concerning and can be a direct result of the infection causing inflammation of the meninges, leading to increased intracranial pressure and neurological damage.

## **Why Each Wrong Option is Incorrect**
- **Option A:** While lethargy and poor feeding are indeed common presentations of neonatal illness, they are nonspecific and can be seen in a wide range of conditions, not just meningitis.
- **Option B:** Jaundice and hepatomegaly are not typical primary presentations of neonatal meningitis but can be seen in other neonatal conditions such as infections, metabolic disorders, or biliary atresia.
- **Option D:** Diarrhea and abdominal distension are more commonly associated with gastrointestinal issues rather than directly with meningitis.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that neonatal meningitis can present without the classic signs of meningismus (like neck stiffness) seen in older children and adults. Therefore, a high index of suspicion is crucial in newborns with risk factors for infection, and clinicians should not hesitate to perform a lumbar puncture when suspecting meningitis.

## **Correct Answer:** C. seizures and vomiting
