A 20-year-old man comes to the emergency department because of fever and altered mental status. Physical examination reveals a petechial rash on his trunk and arms and a positive Kernig sign. Two hours later he becomes hypotensive, and fluid resuscitation does not restore his blood pressure. A comprehensive metabolic panel is obtained and shows a sodium level of 119 mEq/L and potassium level of 6.0 mEq/L. A repeat physical examination shows generalized abdominal tenderness elicited upon deep palpation.
