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 A
Explanation
Choice A rationale:
Tender, bleeding gums could be a sign of phenytoin-induced gingival hyperplasia, a serious adverse effect of phenytoin. This condition requires immediate medical attention to prevent further complications.
Choice B rationale:
Increased facial hair is not a common adverse effect of phenytoin and may not require immediate medical attention. It could be due to other factors or conditions.
Choice C rationale:
Constipation is a common side effect of many medications, including phenytoin. While it should be monitored, it does not require immediate reporting to the provider unless severe or persistent.
Choice D rationale:
A skin rash can be an adverse effect of phenytoin, but it does not necessarily require immediate reporting unless it is severe, accompanied by other symptoms, or indicative of a serious allergic reaction.
Correct Answer is B
Explanation
Choice A rationale:
Hemoptysis, which is the coughing up of blood, is not typically associated with a urinary tract infection (UTI). It is more commonly related to respiratory or pulmonary issues.
Choice B rationale:
Hematuria, the presence of blood in the urine, is a common finding in a UTI. Inflammation and infection in the urinary tract can lead to the presence of blood cells in the urine.
Choice C rationale:
Hyperglycemia, an elevated blood glucose level, is not directly related to a UTI. It may be seen in individuals with diabetes, but it is not a typical finding in a UTI.
Choice D rationale:
Hypocalcemia, a low level of calcium in the blood, is not a characteristic finding in a UTI. UTIs primarily affect the urinary system and do not directly involve calcium metabolism.
