A nurse is preparing a child who has suspected bacterial meningitis for a lumbar puncture. Which of the following cerebrospinal fluid findings supports the diagnosis?

Choice A rationale:
Placing a toddler in a side-lying position on the affected side after administering otic medication is not recommended. This position can cause the medication to leak out, reducing its effectiveness, and can also increase the risk of infection. It's important to keep the medication in the ear canal for an adequate amount of time to allow it to work properly.
Choice B rationale:
Allowing the medication to reach room temperature prior to administration is not a critical step for otic medications. While warming certain medications can reduce discomfort, this is not a specific requirement for ear drops. Ensuring the cleanliness of the ear, proper positioning, and correct administration technique are more important.
Choice C rationale:
The correct choice. Sitting the child in an upright position is the recommended approach for administering otic medication. This position helps ensure that the medication remains in the ear canal and is not immediately expelled. It also facilitates better penetration of the medication into the ear canal, increasing its effectiveness.
Choice D rationale:
Gently pulling a child's ear upward is a technique used for administering otic medications to straighten the ear canal and allow better access to the medication. However, this step alone is not sufficient. Proper positioning of the child is equally important to prevent the medication from leaking out.

Choice A rationale:
A 2 cm scalp laceration, while a concern, is not the nurse's priority in this scenario. The child's head injury could potentially be serious, but priority should be given to neurological assessments and signs of increased intracranial pressure.
Choice B rationale:
Nasal discharge negative for glucose is not indicative of a major issue in this context. While cerebrospinal fluid (CSF) leaking from the nose after head trauma is a concern, it is not mentioned in this scenario, and this choice does not take precedence over other neurological signs.
Choice C rationale:
This is the correct answer. Asymmetric pupils can be a sign of a serious neurological issue, such as a brain injury or increased intracranial pressure. It requires immediate attention and further evaluation to assess the child's neurological status and determine the extent of the injury.
Choice D rationale:
A negative Babinski reflex is a normal finding in this context and does not require immediate priority attention. The Babinski reflex is typically present in infants and disappears as the child grows older. Its absence is expected in older children and adults.
