What condition would contraindicate examination of the pharynx?

Rationale: A. Peritonsillar abscess may be evaluated with careful oral examination, though manipulation can be uncomfortable. B. Acute epiglottitis is a medical emergency in which examination of the pharynx can precipitate complete airway obstruction. Therefore, direct visualization of the throat should be avoided, and airway management is the priority. C. Uvulitis can be examined carefully; it is not an absolute contraindication. D. Bacterial tracheitis affects the lower airway and does not specifically contraindicate pharyngeal examination, though caution is advised if airway compromise is present.
