Choice A rationale:

Fever is a common sign of meningitis, regardless of its cause. It is often accompanied by other symptoms such as headache and irritability.

Choice B rationale:

A high-pitched cry is a classic sign of meningitis in infants and young children, especially in bacterial meningitis cases. The inflammation in the meninges can cause irritation of the central nervous system, leading to this specific cry.

Choice C rationale:

Altered mental status is a significant sign of meningitis, especially when bacterial pathogens are involved. It can range from lethargy and confusion to more severe manifestations like seizures and coma.

Choice D rationale:

Weight loss is not typically associated with meningitis. The condition usually presents with acute symptoms such as fever, headache, and neck stiffness, rather than chronic symptoms like weight loss.

Choice E rationale:

A stiff neck is a hallmark sign of meningitis, particularly in cases of bacterial meningitis. It is caused by the irritation and inflammation of the meninges surrounding the spinal cord.
