The nurse is assisting the neurologist with a lumbar puncture on a patient with possible meningitis. Which post-procedure teaching point is the highest priority for the patient?

Choice A reason: This is incorrect. Administering a dose of a prescribed antiepileptic drug is an appropriate intervention, but it should be done during the seizure, not after. Positioning the person supine is also not recommended, as it can compromise the airway and increase the risk of aspiration.

Choice B reason: This is incorrect. Wrapping the patient in warm blankets and hyperextending their neck are both harmful actions, as they can increase the body temperature and obstruct the airway. The patient should be kept cool and comfortable, and their head should be tilted to the side or supported with a pillow.

Choice C reason: This is incorrect. Offering the patient a crossword to work on to promote mental stimulation is not an essential intervention, and it may not be feasible or appropriate for a patient who has just experienced a prolonged seizure. The patient may need rest and observation, not cognitive tasks.

Choice D reason: This is correct. Establishing that the patient has a patent airway after the seizure ends and assessing for breathing are the most important interventions, as they ensure the oxygenation and ventilation of the patient. The nurse should also monitor the vital signs, neurological status, and blood glucose levels of the patient.

Choice A reason: Assessing the patient for potential visual deficits is not the primary purpose of evaluating pupillary response. Visual deficits may result from damage to the optic nerve or the occipital lobe, but they are not directly related to pupillary response.

Choice B reason: Assessing the patient's level of consciousness is an important part of the neurological assessment, but it is not done by evaluating pupillary response alone. Level of consciousness is determined by observing the patient's responsiveness to verbal and physical stimuli, as well as their orientation to person, place, time, and situation.

Choice C reason: Assessing the patient for increased intracranial pressure is the best explanation for evaluating pupillary response. Increased intracranial pressure is a life-threatening condition that can result from brain swelling, bleeding, or infection. It can cause compression of the brainstem and the cranial nerves, leading to changes in pupillary size, shape, and reactivity. Pupillary response is a sensitive indicator of intracranial pressure and brainstem function.

Choice D reason: Assessing the patient for cerebrospinal fluid leakage is not the main reason for evaluating pupillary response. Cerebrospinal fluid leakage can occur after a craniotomy due to a tear in the dura mater, the membrane that covers the brain and spinal cord. It can cause symptoms such as headache, nausea, vomiting, and meningitis. However, it does not affect pupillary response unless it causes increased intracranial pressure.
