A patient with a spinal cord lesion at T4 tells the nurse that he has a headache and feels flushed. The blood pressure is significantly elevated to 190/100. The first action by the nurse is to:

Choice A reason: Rechecking all of the patient's vital signs is a good practice, but it is not the priority action in this scenario. The patient's symptoms indicate a potential case of autonomic dysreflexia, a life-threatening condition that requires immediate action to reduce blood pressure and address the cause. Rechecking vital signs alone will not resolve the underlying issue.Choice B reason: Elevating the patient's knees and lowering the head of the bed is not an appropriate action in this situation. This position could potentially increase intracranial pressure and exacerbate the patient's condition. The focus should be on measures that will help lower the blood pressure and alleviate the symptoms of autonomic dysreflexia.Choice C reason: The priority action is to elevate the head of the bed immediately and notify the provider. Elevating the head of the bed helps to decrease blood pressure and improve venous return. Promptly notifying the provider ensures that the patient receives timely medical intervention to address the underlying cause of autonomic dysreflexia, which is critical for preventing further complications.Choice D reason: Administering PRN Tylenol for the patient's headache is not the priority in this situation. While pain management is important, the patient's symptoms suggest a more severe condition (autonomic dysreflexia) that requires immediate attention to lower blood pressure and address the root cause. Pain medication alone will not resolve the underlying issue and could delay necessary interventions.
