Final answer:
Nasotracheal suctioning should not be delegated to a Nursing Assistant Personnel because it is more invasive and requires clinical skill and assessment, typically done by registered nurses.
Step-by-step explanation:
The task that should NOT be delegated to a Nursing Assistant Personnel (NAP) is B. Nasotracheal suctioning. Nasotracheal suctioning is a procedure to remove respiratory secretions from a patient's airway with the aid of a suction catheter. It requires clinical skill and assessment and thus falls within the scope of practice for licensed personnel, such as registered nurses, rather than NAPs. NAPs can typically take on tasks such as C. Pulse oximetry, D. Oral care, and A. Oropharyngeal suctioning under certain conditions, but more invasive procedures like nasotracheal suctioning must be performed by the licensed nursing staff.
