What positioning error occurred if the base of the skull superimposes the odontoid process on the AP open mouth image?
the head was rotated
the chin was too extended
the chin was too flexed
the patient's mouth wasn't fully opened
the chin was too extended
Rationale: If the base of the skull superimposes the odontoid process, the chin needs to be tucked down to align with the teeth. This will push the base of the skull up.
