The practical nurse (PN) is assigned to care for a client who had an endoscopic procedure in which a local anesthetic was sprayed on the throat. Which priority action should the PN include in this client's plan of care?

A. Observe for belching: While belching is a normal gastrointestinal function, it is not a priority safety concern after a local anesthetic is applied to the throat. It does not directly indicate airway protection or swallowing ability. B. Inquire about a sore throat: Sore throat is a common minor side effect after endoscopy, but it does not pose an immediate risk to the client. Assessing discomfort is secondary to ensuring safety. C. Assess the gag reflex: The priority is to assess the gag reflex before allowing the client to eat or drink. Local anesthetic can temporarily suppress the reflex, increasing the risk of aspiration if swallowing occurs prematurely, making this a critical safety intervention. D. Instruct the client to speak: Asking the client to speak can help assess vocal cord function but does not provide reliable information about airway protection or swallowing safety, which are more urgent concerns post-procedure.
