The nurse assesses a client with a history of migraine headaches. Which clinical manifestation would the nurse identify as an early sign of a migraine with an aura?

Choice A reason: Completing a halo test with the fluid is the initial intervention that the nurse should perform, as it can help to determine if the fluid is cerebrospinal fluid (CSF) or not. CSF is the fluid that surrounds and protects the brain and spinal cord, and it can leak from the nose or ears after a head injury. A halo test involves placing a drop of the fluid on a piece of filter paper or gauze and observing the color and shape of the stain. If the fluid is CSF, it will form a yellowish ring around a central blood spot, creating a halo effect.

Choice B reason: Taping a sterile gauze pad under the nose and monitoring the amount of fluid is not the initial intervention that the nurse should perform, as it does not help to identify the type of fluid. It may also increase the risk of infection or pressure on the brain if the fluid is CSF.

Choice C reason: Documenting the presence of rhinorrhea is not the initial intervention that the nurse should perform, as it does not help to diagnose or treat the condition. Rhinorrhea is the medical term for a runny nose, which can have many causes, such as allergies, colds, or sinus infections. It is not a specific sign of a head injury or CSF leakage.

Choice D reason: Informing the physician of the assessment is an important intervention that the nurse should perform, but not the initial one. The nurse should first confirm if the fluid is CSF or not, as this can affect the management and prognosis of the patient. The nurse should then report the findings and the patient's vital signs, neurological status, and other relevant information to the physician.

Choice A reason: This is correct. Monitoring of neurologic status is a priority intervention for a patient with bacterial meningitis, as the infection can cause inflammation and damage to the brain and spinal cord. The nurse should assess the patient's level of consciousness, pupillary response, cranial nerve function, and signs of increased intracranial pressure.

Choice B reason: This is incorrect. Infusion of large volumes of isotonic intravenous fluids is not indicated for a patient with bacterial meningitis, as it can worsen the cerebral edema and increase the intracranial pressure. The patient should receive adequate hydration, but not excessive fluids.

Choice C reason: This is incorrect. Standard precautions are not sufficient for a patient with bacterial meningitis, as the infection can be transmitted through respiratory droplets. The patient should be placed on droplet precautions, which include wearing a mask, gloves, and gown, and limiting the contact with other patients and visitors.

Choice D reason: This is incorrect. Distraction activities to reduce long periods of sleep are not appropriate for a patient with bacterial meningitis, as the patient may need rest and sedation to reduce the agitation and pain. The nurse should provide a quiet and dark environment, and avoid unnecessary stimuli that can increase the intracranial pressure.
