NREMT Paramedic Cognitive ExamMedicalEasy
A 40-year-old male presents with sudden onset of severe headache, described as 'the worst headache of my life.' He is alert but reports photophobia and neck stiffness. His vital signs are stable, and neurological examination is non-focal. What condition should be HIGHLY suspected?
- ATension headache
- BSubarachnoid hemorrhage
- CMigraine headache
- DCluster headache
Show answer & explanationAnswer & explanation
Correct answer: B. Subarachnoid hemorrhage
The sudden onset of a 'thunderclap' headache, described as the 'worst headache of my life,' combined with photophobia and neck stiffness (meningismus), is a classic presentation of a subarachnoid hemorrhage (SAH). This is a medical emergency requiring immediate investigation.
Why the other options are wrong
- A. Tension headaches are usually dull, bilateral, and do not present with sudden severe onset or meningismus.
- C. Migraines typically have associated features like aura, throbbing pain, and are often unilateral, but usually don't present as the 'worst headache of life' with sudden onset and meningismus.
- D. Cluster headaches are severe, unilateral headaches associated with autonomic symptoms (e.g., lacrimation, rhinorrhea) but not typically described as 'worst headache of life' with sudden onset and neck stiffness.
Subarachnoid Hemorrhage (SAH)
Subarachnoid hemorrhage is bleeding into the subarachnoid space, often caused by a ruptured aneurysm, and classically presents as a sudden, severe 'thunderclap' headache.
- Sudden onset, 'worst headache of my life' is a hallmark symptom.
- Associated with neck stiffness (meningismus) and photophobia.
- Requires immediate neuroimaging (CT scan) and neurosurgical consultation.
