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 A
Explanation
Choice A Reason: This is correct because the patient's Glasgow Coma Scale score is 9. The Glasgow Coma Scale is a tool that assesses the level of consciousness of a patient with a head injury by measuring three parameters: eye opening, verbal response, and motor response. The patient's eye opening score is 3 (opens eyes to verbal command), verbal response score is 4 (confused speech), and motor response score is 2 (withdraws from pain). The total score is the sum of these three scores, which is 9.
Choice B Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 11. To get a score of 11, the patient would need to have a higher motor response score, such as 4 (withdraws to touch) or 5 (localizes to pain).
Choice C Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 15. To get a score of 15, the patient would need to have the highest scores for all three parameters, such as 4 (opens eyes spontaneously), 5 (oriented speech), and 6 (obeys commands).
Choice D Reason: This is incorrect because the patient's Glasgow Coma Scale score is not 13. To get a score of 13, the patient would need to have a higher verbal response score, such as 5 (oriented speech).
Correct Answer is D
Explanation
Choice A Reason: Head trauma is not one of the top causes of blindness in the United States, but rather a possible cause of it. Head trauma can damage the optic nerve, retina, or brain, leading to vision loss or impairment.
Choice B Reason: Cardiovascular disease is not one of the top causes of blindness in the United States, but rather a risk factor for it. Cardiovascular disease can affect the blood supply and oxygen delivery to the eyes, leading to conditions such as glaucoma, macular degeneration, or retinal vein occlusion.
Choice C Reason: Syphilis is not one of the top causes of blindness in the United States, but rather a rare cause of it. Syphilis is a sexually transmitted infection that can affect the eyes, leading to inflammation, scarring, or detachment of the retina.
Choice D Reason: This is the correct choice. Diabetic retinopathy is one of the top causes of blindness in the United States, affecting about 4.1 million adults. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina, leading to bleeding, swelling, or leakage of fluid. It can cause blurred vision, floaters, or blindness if left untreated.
