The following can occur due to meningococcal infection-
**Core Concept**
Meningococcal infection, caused by Neisseria meningitidis, is a severe bacterial infection that can lead to meningitis and sepsis. The infection can cause inflammation of the meninges, leading to complications such as brain damage, hearing loss, and even death.
**Why the Correct Answer is Right**
The correct answer is related to Waterhouse-Friderichsen syndrome, a rare but life-threatening complication of meningococcal sepsis. This syndrome occurs due to adrenal hemorrhage, which leads to acute adrenal insufficiency. The adrenal glands are responsible for producing hormones such as cortisol and aldosterone, which regulate the body's response to stress and maintain electrolyte balance. In Waterhouse-Friderichsen syndrome, the adrenal glands are damaged, leading to a deficiency of these hormones.
**Why Each Wrong Option is Incorrect**
* **Option A:** While meningococcal infection can cause meningitis, it is not the primary cause of this condition.
* **Option B:** Hearing loss is a possible complication of meningococcal infection, but it is not the most severe or life-threatening consequence.
* **Option C:** Meningococcal infection can cause a rash, but this is not the most significant complication associated with the infection.
**Clinical Pearl / High-Yield Fact**
Meningococcal infection can progress rapidly to sepsis and Waterhouse-Friderichsen syndrome, making early recognition and treatment critical to prevent long-term damage and death.
**Correct Answer:** C.
