Final answer:
The nurse is employing a Yankauer suction technique using a tonsil tip catheter to clear mouth secretions.
Step-by-step explanation:
The nurse at the health care facility is using a Yankauer suction technique to remove secretions from the mouth of a client with chest congestion. The Yankauer (also spelled Yankeur) is a rigid, plastic suction tool which is often used for oral suctioning. It is specifically designed to allow for effective suction without causing damage to the surrounding tissue. The Yankauer suction tip is a rigid, curved instrument that is commonly used for suctioning secretions from the mouth and pharynx. It is designed to effectively remove oral secretions while minimizing the risk of aspiration. This technique is essential when clients are unable to clear their own secretions due to a decrease in consciousness or if they have an excessive amount of mucus.
