A nurse is caring for a client who has quadriplegia from a spinal cord injury and reports having a severe headache. The nurse obtains a blood pressure reading of 210/108 mm Hg and suspects the client is experiencing autonomic dysreflexia. Which of the following actions should the nurse take first?

Choice A Reason: This choice is incorrect because slowing the rate to 50 mL/hr may not be enough to prevent cerebral edema, which is a common complication of head injury. Cerebral edema is a swelling of the brain tissue due to increased fluid accumulation. It can cause increased intracranial pressure (ICP), which can lead to brain damage or death. Therefore, the nurse should limit the fluid intake of the client with head injury to avoid worsening the condition.

Choice B Reason: This choice is incorrect because increasing the rate to 250 mL/hr may cause fluid overload, which can also increase the ICP and worsen the cerebral edema. Fluid overload is a condition in which the body has too much fluid, which can impair the function of the heart, lungs, and kidneys. Therefore, the nurse should avoid giving too much fluid to the client with head injury.

Choice C Reason: This choice is correct because slowing the rate to 20 mL/hr may help to maintain adequate hydration and electrolyte balance, while preventing fluid overload and cerebral edema. This is a conservative approach that can be used until the client's neurological status and ICP are assessed and monitored.

Choice D Reason: This choice is incorrect because continuing the rate at 125 mL/hr may not be appropriate for the client with head injury, depending on their individual needs and condition. The nurse should adjust the fluid rate according to the client's vital signs, urine output, serum osmolality, and ICP. Therefore, the nurse should not assume that this rate is optimal for the client without further evaluation.

Choice A: Evaluating chest expansion is the first action that the nurse should take, because it assesses the client's respiratory status and potential for pneumothorax, which is a life-threatening condition that can result from chest trauma. The nurse should compare the movement of both sides of the chest and listen for breath sounds.

Choice B: Checking pupillary response to light is an important action, but not the first one, because it assesses the client's neurological status and potential for brain injury. The nurse should observe the size, shape, and symmetry of the pupils and their reaction to light.

Choice C: Checking the client's response to questions about place and time is another important action, but not the first one, because it assesses the client's level of consciousness and orientation. The nurse should ask the client simple questions such as their name, date, and location.

Choice D: Assessing the capillary refill is a less important action, and not the first one, because it assesses the client's peripheral circulation and tissue perfusion. The nurse should press on the client's nail beds or fingertips and observe how quickly the color returns.
