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 C
Explanation
The fracture is on the diaphysis. The femur, which is the thigh bone, is made up of three parts: the head, neck, and diaphysis. The diaphysis is the long, cylindrical part of the bone between the proximal and distal ends. When reporting the location of a fracture on the femur, it is most accurate to describe the location as being on the diaphysis.
Choice A, the fracture is on the epiphyses, is incorrect because the epiphyses are the rounded ends of the bone and are not typically involved in long bone fractures.
Choice B, the fracture is on the tuberosity, is incorrect because the tuberosity is a bony prominence where muscles attach and is not typically involved in long bone fractures.
Correct Answer is B
Explanation
Provide the client with warm fluids. The shivering can occur due to the anesthesia, the effect of the surgery, or cold temperature in the operating room. The shivering increases the client's oxygen consumption and carbon dioxide production, which can cause hypoxia, hypercapnia, and acidosis. The nurse should provide warm fluids to prevent hypothermia and warm blankets to reduce shivering.
Option A, placing the client on a hypothermia blanket, is incorrect because it is used to lower body temperature, not raise it.
Option C, covering the client with a light blanket, is incorrect because it is not enough to keep the client warm.
Option D, ensuring that the room temperature is below 70°F, is incorrect because it is too cold for the client and can increase shivering.
