Answer: The correct answer is : Evaluate the presence of a gag reflex
Explanation: Because of the administration of a local anesthetic during bronchoscopy, fluids and food should be withheld until the gag reflex returns to prevent aspiration. Ice chips must not be given until the gag reflex returns. Coughing should not be encouraged because it might initiate bleeding from the biopsy site. Lying flat will increase the risk for aspiration.
