A nurse is assessing a client who has suffered a traumatic brain injury. When the nurse applies a stimuli to the client, which of the following responses by the client indicates that the client has suffered an extensive cervical spine injury?

Choice A Reason: Hemorrhage is not a complication of an acute spinal cord injury, but rather a possible cause of it. Hemorrhage can occur due to trauma or rupture of blood vessels in or around the spinal cord, leading to compression and damage of the nerve tissue.

Choice B Reason: This is the correct choice. Spinal shock is a complication of an acute spinal cord injury that occurs within minutes to hours after the injury. It is characterized by loss of sensation, motor function, reflexes, and autonomic function below the level of injury. It is caused by transient disruption of nerve conduction and synaptic transmission in the spinal cord.

Choice C Reason: Apoptosis is not a complication of an acute spinal cord injury, but rather a cellular process that occurs after it. Apoptosis is programmed cell death that occurs in response to injury or stress. It can lead to further loss of neurons and glial cells in the spinal cord over time.

Choice D Reason: Neurogenic shock is a complication of an acute spinal cord injury that occurs within hours to days after the injury. It is characterized by hypotension, bradycardia, and peripheral vasodilation due to loss of sympathetic tone and unopposed parasympathetic activity. It is caused by disruption of autonomic pathways in the spinal cord.

Choice A reason: This is incorrect because using sign language when communicating with the client is not an appropriate action for the nurse to take. Sign language is a form of communication that uses hand gestures, facial expressions, and body movements. It is not a universal language and requires training and practice. The nurse should not assume that the client knows or prefers sign language unless they have indicated so.

Choice B reason: This is incorrect because speaking loudly and into the client's good ear is not an appropriate action for the nurse to take. Speaking loudly can distort the sound quality and cause discomfort or irritation to the client. Speaking into the client's good ear can also create a sense of imbalance and isolation. The nurse should speak at a normal volume and tone, and face the client directly.

Choice C reason: This is the correct answer because speaking directly to the client in a normal, clear voice is an appropriate action for the nurse to take. Speaking directly to the client can help them see the nurse's mouth movements and facial expressions, which can enhance understanding and communication. Speaking in a normal, clear voice can help convey the message clearly and respectfully.

Choice D reason: This is incorrect because sitting by the client's side and speaking very slowly is not an appropriate action for the nurse to take. Sitting by the client's side can make it difficult for them to see the nurse's face and hear their voice. Speaking very slowly can also make the message unclear and patronizing. The nurse should sit in front of the client and speak at a normal pace.
