Final answer:
Suctioning a patient is performed in medical settings to remove secretions or foreign substances from the airway. The best suction catheter for oropharyngeal suctioning is typically a Yankauer or tonsil tip catheter.
Step-by-step explanation:
In medical settings, suctioning a patient is performed when there is a need to remove secretions or foreign substances from the airway. This may be necessary in cases of excessive mucus production, choking, or respiratory distress. To determine if suctioning is required, healthcare professionals assess the patient's airway, breathing, and oxygen levels. If necessary, a suction catheter is used to clear the oropharynx. The best suction catheter for oropharyngeal suctioning would typically be a Yankauer or tonsil tip catheter, which are designed specifically for the oropharynx. These catheters have a larger diameter and a bulbous tip to help remove secretions effectively.
