A client admitted after a motor vehicle accident arrives with a Glasgow coma score (GCS) of 14 with a mild headache. 4 hours later, the client's GCS has decreased to 10, and now has a dilated pupil on the left side. Which of the following acute traumatic brain injuries does the nurse suspect the client has suffered?
Laceration
Acute subdural hematoma
Intracerebral hemorrhage
Epidural hematoma
The Correct Answer is D
Choice A reason: This is incorrect because laceration is not an acute traumatic brain injury, but a type of wound that involves tearing or cutting of the skin or other tissues. Laceration can occur as a result of a motor vehicle accident, but it does not cause changes in the GCS or pupil size. The nurse should assess the client's skin for any signs of laceration, such as bleeding, swelling, or infection.
Choice B reason: This is incorrect because acute subdural hematoma is not likely to cause a dilated pupil on the left side. Acute subdural hematoma is a type of traumatic brain injury that involves bleeding between the dura mater and the arachnoid mater, which are two layers of the meninges that cover the brain. An acute subdural hematoma can cause a rapid decrease in the GCS, but it usually causes a dilated pupil on the same side as the injury, not on the opposite side.
Choice C reason: This is incorrect because intracerebral hemorrhage is not likely to cause a dilated pupil on the left side. Intracerebral hemorrhage is a type of traumatic brain injury that involves bleeding within the brain tissue itself. Intracerebral hemorrhage can cause a gradual decrease in the GCS, but it usually causes neurological deficits that correspond to the location of the bleeding, such as weakness, numbness, or aphasia, not pupillary changes.
Choice D reason: This is correct because epidural hematoma can cause a dilated pupil on the left side. Epidural hematoma is a type of traumatic brain injury that involves bleeding between the dura mater and the skull. Epidural hematoma can cause a lucid interval, which is a period of normal consciousness followed by a sudden decrease in the GCS, and a dilated pupil on the opposite side of the injury, due to compression of the third cranial nerve. The nurse should notify the provider immediately and prepare for emergency surgery.

Correct Answer is D
Explanation
Choice A Reason: This is incorrect because nystagmus is not a response to stimuli, but a condition that causes involuntary eye movements. Nystagmus can be caused by various factors, such as inner ear disorders, brain lesions, or drug toxicity, but not necessarily by cervical spine injury.
Choice B Reason: This is incorrect because decorticate positioning is a response to stimuli that indicates damage to the cerebral cortex or the corticospinal tract. Decorticate positioning is characterized by flexion of the arms and extension of the legs. It does not indicate cervical spine injury, which affects the spinal cord below the brainstem.
Choice C Reason: This is incorrect because lack of any response to stimuli can indicate various levels of brain damage or coma, but not specifically cervical spine injury. Lack of any response can also be influenced by other factors, such as sedation, hypothermia, or shock.
Choice D Reason: This is correct because decerebrate positioning is a response to stimuli that indicates damage to the brainstem or the upper cervical spine. Decerebrate positioning is characterized by extension and outward rotation of the arms and legs. It indicates a severe and life-threatening injury that can impair vital functions, such as breathing and blood pressure.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because turning off the lights and TV and closing the door may increase the client's anxiety and confusion. The nurse should provide adequate lighting and familiar objects to help orient the client.
Choice B Reason: This is incorrect because using restraints may increase the risk of injury, infection, and psychological distress for the client. The nurse should use restraints only as a last resort and with a physician's order.
Choice C Reason: This is incorrect because asking for a sedative may not address the underlying cause of the agitation. The nurse should use non-pharmacological interventions first, such as calming music, massage, or aromatherapy.
Choice D Reason: This is correct because identifying the cause of the agitation may help resolve it. The nurse should assess for possible triggers, such as pain, hunger, thirst, infection, or environmental factors.
