The nurse is caring for a patient who sustained a spinal cord injury (SCI) at T1. The alarm on the monitor sounds because the patient's blood pressure is 86/50 and the heart rate is 44. The nurse's priority action would be to:

place the client in reverse Trendelenburg position.

administer intravenous (IV) fluids to increase cardiac output.

ask the patient care tech to check on the patient.

assess the patient's neurological status and repeat vital signs.
