A nurse in an emergency department is assessing a client who has a basilar skull fracture and serosanguineous nasal discharge following a motor vehicle crash. Which of the following findings should the nurse identify as reliable for determining that the discharge is cerebrospinal fluid?
Papilledema.
Halo sign.
Racoon's eyes.
Elevated WBCs.
The Correct Answer is B
Choice A rationale:
Papilledema refers to swelling of the optic disc in the eye, which can occur due to increased intracranial pressure. While it may be present in cases of basilar skull fracture, it is not a reliable finding for determining the discharge of cerebrospinal fluid (CSF).
Choice B rationale:
The halo sign is a reliable finding for determining that the nasal discharge is cerebrospinal fluid. The halo sign is characterized by a ring of blood surrounded by a clear or yellowish fluid (CSF) on a dressing or tissue. This occurs because blood from the fracture mixes with the clear CSF, creating a distinct appearance.
Choice C rationale:
Racoon's eyes, also known as periorbital ecchymosis, is a term used to describe bruising around the eyes. While it can be seen in basilar skull fractures, it is not specific to cerebrospinal fluid leakage and, therefore, not reliable for identifying the nasal discharge as CSF.
Choice D rationale:
Elevated white blood cells (WBCs) in the nasal discharge can indicate infection, inflammation, or an immune response. However, it does not provide direct evidence that the discharge is cerebrospinal fluid, so this is not a reliable finding for determining the nature of the nasal discharge in this context.

Correct Answer is B
Explanation
Choice A rationale:
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
Choice B rationale:
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
Choice C rationale:
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
Choice D rationale:
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.
Correct Answer is D
Explanation
Choice A rationale:
Severe headache can be a symptom of a subdural hematoma, but it is not the earliest manifestation of a change in neurological status. Other symptoms may appear before a severe headache, such as an altered level of consciousness.
Choice B rationale:
Bradycardia can occur with a subdural hematoma, especially as intracranial pressure increases. However, it is not the earliest manifestation of a change in neurological status. Changes in heart rate may occur later in the progression of the condition.
Choice C rationale:
Widened pulse pressure can also occur in patients with a subdural hematoma due to increased intracranial pressure. However, it is not the earliest manifestation of a change in neurological status. Other neurological signs would likely appear before changes in pulse pressure are evident.
Choice D rationale:
Change in level of consciousness is the earliest manifestation of a change in neurological status with a subdural hematoma. As intracranial pressure increases, the brain's functioning can be affected, leading to alterations in consciousness, ranging from mild confusion to unconsciousness.
