An older adult is admitted to the hospital following a closed head injury from a fall that resulted in a 5-minute period of unconsciousness. Which priority nursing assessment indicates neurological deterioration in the patient?

Choice A reason: Eyes are deviated to the right is an assessment finding that indicates increased intracranial pressure and possible herniation of the brain. It is a sign of cranial nerve III palsy, which affects the movement of the eye and the size of the pupil. It is a medical emergency that requires immediate intervention.

Choice B reason: Amnesia to the cause of the trauma is an assessment finding that indicates memory loss and possible concussion. It is a sign of damage to the temporal lobe, which is involved in memory formation and retrieval. It is not a medical emergency, but it requires further evaluation and monitoring.

Choice C reason: Complaint of mild headache is an assessment finding that indicates pain and discomfort. It is a common symptom of traumatic brain injury, but it is not specific or severe. It can be managed with analgesics and rest.

Choice D reason: Pupils constrict from 5 mm to 2 mm with direct light stimulus is an assessment finding that indicates normal pupillary response. It is a sign of intact cranial nerve II and III function, which control the vision and the pupil size. It is not a cause for concern or notification.

Choice A reason: Maintaining pressure to the puncture site and observing for drainage is the priority nursing intervention for a patient who had a lumbar puncture. It helps to prevent bleeding, hematoma, and cerebrospinal fluid leakage, which can cause complications such as infection, headache, or nerve damage.

Choice B reason: Completing a pain assessment and administering an ordered analgesic, as needed, is an important nursing intervention for a patient who had a lumbar puncture, but it is not the priority. Lumbar puncture can cause mild to moderate pain and discomfort at the puncture site, which can be relieved by analgesics, ice packs, or massage.

Choice C reason: Informing the patient they may feel pressure and sharp pain in their lower back for several hours is an important nursing intervention for a patient who had a lumbar puncture, but it is not the priority. Lumbar puncture can cause transient sensations of pressure and pain in the lower back, which can be reduced by lying flat, avoiding sudden movements, and drinking fluids.

Choice D reason: Assessing pulses distal to the lumbar puncture site every two hours is not an appropriate nursing intervention for a patient who had a lumbar puncture. Lumbar puncture does not affect the blood circulation to the lower extremities, unless there is a complication such as hematoma or nerve compression. Therefore, the nurse should monitor the neurological status, vital signs, and signs of infection or bleeding.
