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 earphones are not used in the Rinne test. The Rinne test compares air conduction and bone conduction of sound using a tuning fork.
Choice B Reason: This is incorrect because electrodes are not used in the Rinne test. Electrodes are used in electroencephalography (EEG), which measures brain activity.
Choice C Reason: This is incorrect because a probe is not used in the Rinne test. A probe is used in tympanometry, which measures the pressure and mobility of the eardrum.
Choice D Reason: This is correct because a tuning fork is used in the Rinne test. The tuning fork is placed on the mastoid process behind the ear and then moved near the ear canal to compare the sound perception.
Correct Answer is D
Explanation
Choice A Reason: To administer medications and electrolytes is not the best reply for why the client will need the NG tube, because this is not the primary purpose of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Medications and electrolytes can be given through the IV route.
Choice B Reason: To dilate the stomach as a presurgical preparation is not the best reply for why the client will need the NG tube, because this is not a valid indication for the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Dilation of the stomach is not a goal of presurgical preparation, but rather an adverse effect of gastric obstruction.
Choice C Reason: You will not be able to eat for several days is not the best reply for why the client will need the NG tube, because this is not a complete or accurate explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. The client will not be able to eat for several days because of the NPO diet, which is necessary to rest the inflamed peritoneum and reduce the risk of complications.
Choice D Reason: To remove secretions and decompress your stomach is the best reply for why the client will need the NG tube, because this is a clear and correct explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration, which are common symptoms of acute peritonitis. By removing secretions and decompressing the stomach, the NG tube can reduce pain, inflammation, and infection in the abdominal cavity.
