The nurse assesses a patient with a recent spinal cord injury at the level of thoracic 5 vertebrae. The patient's blood pressure is 184/95 mm Hg, has a flushed face and blurred vision. What priority action would the nurse complete first?

Choice A reason: Notifying the health care provider of the patient's status is an important action, but not the first priority. The nurse should first assess the patient for any possible triggers of the autonomic dysreflexia, which is a life-threatening condition that occurs in patients with spinal cord injury above the level of T6. It is characterized by a sudden and severe increase in blood pressure, flushing, sweating, headache, and blurred vision.

Choice B reason: Assessing patient for tight clothing around the waist or a full bladder is the first priority action. These are common triggers of autonomic dysreflexia, which cause irritation or stimulation of the nerves below the level of injury. The nurse should remove any tight clothing, catheterize the patient if needed, or perform a bowel evacuation to relieve the pressure and prevent further complications.

Choice C reason: Reviewing the medication administration record for an antihypertensive order is a secondary action, after identifying and removing the trigger of autonomic dysreflexia. The nurse should administer the prescribed antihypertensive medication, such as nifedipine or nitroglycerin, to lower the blood pressure and prevent stroke, seizure, or cardiac arrest.

Choice D reason: Initiating oxygen via a nasal cannula and elevating patient's legs is not an appropriate action for a patient with autonomic dysreflexia. Oxygen therapy is not indicated for this condition, unless the patient has hypoxia or respiratory distress. Elevating the patient's legs can worsen the blood pressure by increasing the venous return and the cardiac output. The nurse should keep the patient in a sitting position to promote the blood flow to the lower extremities and reduce the blood pressure.
