A nurse is providing education on meningococcal meningitis prevention. Which statement by the nurse is accurate?
"This type of meningitis is mainly seen in infants.”
"It occurs primarily in regions with contaminated water.”
"It can cause death within hours if left untreated.”
"Fungal meningitis has a higher mortality rate than this type.”
The Correct Answer is C
Choice A rationale:
Meningococcal meningitis is not mainly seen in infants. It can affect individuals of all ages, but infants and young children are more susceptible to certain types of bacterial meningitis, such as Haemophilus influenzae type b.
Choice B rationale:
Meningococcal meningitis is primarily transmitted through respiratory droplets, close contact with an infected person, or exposure to contaminated respiratory or throat secretions. It is not primarily linked to regions with contaminated water.
Choice C rationale:
Meningococcal meningitis can progress rapidly and cause death within hours if left untreated. Therefore, early recognition and prompt medical treatment are essential to improve outcomes.
Choice D rationale:
The statement comparing meningococcal meningitis with fungal meningitis' mortality rate is not accurate. While meningococcal meningitis can be severe, fungal meningitis is generally associated with a higher mortality rate, especially in individuals with weakened immune systems.

Correct Answer is A
Explanation
Choice A rationale:
In a temperate region during summer, viral meningitis is more likely to be prevalent in the population. Viral meningitis is most commonly caused by enteroviruses, and these infections tend to be more common in the summer and early fall. Enteroviruses thrive in warm and humid conditions, contributing to the seasonal variation in viral meningitis cases.
Choice B rationale:
Bacterial meningitis can occur throughout the year and is not specifically associated with summer or temperate regions. Bacterial meningitis can result from various bacterial pathogens and is usually a more severe and life-threatening form of meningitis compared to viral meningitis.
Choice C rationale:
Fungal meningitis is not typically associated with temperate regions during the summer. Fungal meningitis is more commonly seen in individuals with compromised immune systems or in specific geographic regions with a higher prevalence of fungal infections.
Choice D rationale:
Parasitic meningitis is not prevalent in temperate regions during the summer. Parasitic meningitis is rare and is usually associated with specific parasitic infections, such as those caused by Naegleria fowleri or Angiostrongylus cantonensis, which are typically found in tropical or subtropical regions.
Correct Answer is C
Explanation
Choice A rationale:
A cloudy appearance of cerebrospinal fluid (CSF) can indicate the presence of white blood cells and bacteria, suggesting an infection. However, it is not specific to bacterial or fungal infection and can also be seen in viral meningitis or non-infectious conditions like multiple sclerosis.
Choice B rationale:
Increased pressure in the CSF may occur in meningitis due to the inflammation and accumulation of fluid. While it can raise suspicion for meningitis, it is not specific to bacterial or fungal infection and can also be observed in other intracranial conditions.
Choice C rationale:
Decreased glucose levels in the CSF are a characteristic finding in bacterial or fungal meningitis. The invading bacteria or fungi consume glucose, leading to lower levels in the CSF compared to normal blood glucose levels. This finding helps differentiate bacterial or fungal meningitis from viral meningitis, where glucose levels are usually normal.
Choice D rationale:
Elevated protein levels in the CSF can be seen in various conditions, including meningitis. While it indicates increased inflammation and breakdown of cells, it is not specific to bacterial or fungal infection and can be present in viral or other forms of meningitis.
