Final answer:
Headache, stiff neck, and light sensitivity are symptoms that raise suspicion for bacterial meningitis, which is an inflammation of the meninges and can be lethal if untreated.
Step-by-step explanation:
Meningitis is a serious condition characterized by inflammation of the protective membranes covering the brain and spinal cord, known as the meninges. The presence of a headache and stiff neck, in conjunction with a complaint that sunlight is "too bright", also referred to as light sensitivity or photophobia, would lead a nurse to suspect the possibility of bacterial meningitis. Light sensitivity is a common symptom associated with meningitis due to the inflammation of the meninges and the resulting irritation it causes, which can affect the optic nerve and the patient's response to light. Additional symptoms of bacterial meningitis to look out for include fever, vomiting, confusion or altered consciousness, and in severe cases, it can lead to brain damage, hearing loss, or even death if not treated urgently with appropriate antibiotics.
