Correct answer: E — Vasovagal syncope

Pallor, sweating, bradycardia, hypotension, and light-headedness around a needle stimulus are typical of vasovagal syncope. Anaphylaxis would more likely include urticaria, airway symptoms, or hypotension after allergen exposure. The pearl is to place the patient supine, elevate legs, maintain airway, and monitor recovery.
