A nurse is caring for a patient with a Fentanyl (Duragesic) patch. She assesses the patient and finds him to be abnormally sleepy, is slurring words, has a glassy far away look in the eyes and is extremely unsteady when attempting to ambulate to the bathroom approximately 10 feet away. These signs/symptoms that the patient is exhibiting appear to be ones related to toxicity. What is the next priority nurse action?
