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 B
Explanation
Choice A reason: This is incorrect because preparing the client for an X-ray is not the first action that the nurse should take. An X-ray can help diagnose possible injuries or fractures, but it is not an urgent test. The nurse should first assess the client's level of consciousness and neurological status using a standardized tool such as the Glasgow Coma Scale.
Choice B reason: This is the correct answer because calculating a Glasgow Coma Score is the first action that the nurse should take. The Glasgow Coma Scale is a tool that measures the level of consciousness based on the eye-opening, verbal response, and motor responses. It can help determine the severity of brain injury and guide further interventions.
Choice C reason: This is incorrect because dimming the lights and turning off the TV are not the first actions that the nurse should take. These are environmental modifications that can help reduce sensory stimulation and prevent agitation or seizures, but they are not as important as assessing the level of consciousness and neurological status.
Choice D reason: This is incorrect because providing analgesics is not the first action that the nurse should take. Analgesics can help relieve pain and discomfort, but they can also alter the level of consciousness and mask neurological signs. The nurse should first assess the level of consciousness and neurological status, and then administer analgesics as prescribed.
Correct Answer is C
Explanation
Choice A Reason: Seasonal allergies are not a cause of delirium, but a common condition that affects the respiratory system and causes symptoms such as sneezing, runny nose, itchy eyes, or coughing.
Choice B Reason: History of GERD is not a cause of delirium, but a chronic condition that affects the digestive system and causes symptoms such as heartburn, regurgitation, chest pain, or difficulty swallowing.
Choice C Reason: Benzodiazepines are a cause of delirium, especially in older adults or those with cognitive impairment. Benzodiazepines are a class of drugs that act on the central nervous system and cause sedation, relaxation, and reduced anxiety. However, they can also impair memory, attention, orientation, and judgment, and lead to confusion, agitation, hallucinations, or delusions.
Choice D Reason: Completed antibiotics 10 days ago are not a cause of delirium, but a treatment for bacterial infections. Antibiotics can have side effects such as nausea, diarrhea, rash, or allergic reactions, but they do not cause delirium unless they are toxic or interact with other medications.
