The nurse is caring for a client experiencing autonomic dysreflexia. Which of the following does the nurse recognize as the source of symptoms?
Autonomic nervous system.
Central nervous system.
Sympathetic nervous system.
Peripheral nervous system.
The Correct Answer is A
Autonomic dysreflexia is a medical emergency characterized by a sudden onset of excessively high blood pressure, sweating, and headache. It is caused by an overactivity of the autonomic nervous system in response to a noxious stimulus below the level of a spinal cord injury.
Choice B is incorrect because the central nervous system includes the brain and spinal cord, while autonomic dysreflexia is caused by a spinal cord injury.
Choice C is incorrect because the sympathetic nervous system is part of the autonomic nervous system and is involved in the response to autonomic dysreflexia.
Choice D is incorrect because the peripheral nervous system includes the nerves that extend from the brain and spinal cord to the rest of the body.

Correct Answer is B
Explanation
During a seizure, the nurse's priority is to ensure the client's safety by protecting them from injury. The nurse should loosen any tight clothing and move furniture or objects that may harm the client. The client should be turned onto their side to prevent aspiration, and suctioning the mouth is not indicated during the seizure. Restraints are not appropriate during a seizure, and inserting a tongue blade between the teeth can cause injury.
