A client is admitted following a motor vehicle collision. When assessing the client's level of consciousness, the nurse notes that the client no longer responds to commands. The nurse initiates a painful stimulus and the client responds by pulling the arms inward with elbows and wrists flexed and extending the legs with the toes pointed downward. Which action should the nurse implement?

The correct answer is **a. Report the finding to the healthcare provider.** Choice A rationale: The nurse should report the finding of the client's response to a painful stimulus to the healthcare provider. This response, known as a decorticate posturing, is an abnormal motor response that indicates a severe brain injury or dysfunction. It is a sign of impaired consciousness and requires immediate medical attention and intervention. Choice B rationale: While documenting the client's response to pain is important, the primary action the nurse should take is to report the finding to the healthcare provider. Decorticate posturing is a neurological emergency that requires prompt medical evaluation and treatment. Choice C rationale: Initiating seizure precautions is not the appropriate action in this case. Decorticate posturing is not a seizure, but rather an abnormal motor response indicating a severe brain injury or dysfunction. Seizure precautions would not be the appropriate intervention. Choice D rationale: Administering a prescribed PRN analgesic is not the appropriate action in this case. Decorticate posturing is a neurological emergency that requires immediate medical attention, not just pain management. Administering an analgesic would not address the underlying neurological issue.
