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 C
Explanation
Verify that the client has adequate IV access.
Choice A rationale:
Administering vasopressin to the client might be necessary to manage the hemorrhage, but before any medication administration, it is crucial to ensure the client has adequate IV access. Vasopressin is a vasoconstrictor and can help control bleeding from esophageal varices, but its effectiveness relies on IV access to deliver the medication promptly.
Choice B rationale:
Requesting blood from the blood bank is essential for a client experiencing significant bleeding. However, the priority action is to verify IV access to administer any necessary blood products.
Choice C rationale:
This is the correct choice. Before initiating any interventions, ensuring the client has appropriate IV access is a priority. Adequate IV access is necessary to administer fluids, medications, or blood products promptly and effectively stabilize the client's blood pressure.
Choice D rationale:
Inserting an indwelling urinary catheter is not the priority action in this situation. While monitoring urine output is important, it should be secondary to addressing the client's hypotension and hemorrhage.
Correct Answer is ["B","D"]
Explanation
Choice A rationale:
Lurasidone does not necessarily need to be taken on an empty stomach. It can be taken with or without food.
Choice B rationale:
Avoiding grapefruit juice is essential with lurasidone as it can interfere with the drug's metabolism and increase the risk of side effects.
Choice C rationale:
Changing positions slowly is relevant for medications that can cause orthostatic hypotension, but lurasidone is not typically associated with this side effect.
Choice D rationale:
Lurasidone can cause insomnia in some individuals, so it is important for the client to be aware of this potential side effect. It is best taken in the evening to minimize this effect.
Choice E rationale:
While involuntary movements (extrapyramidal symptoms) can occur with some antipsychotic medications, lurasidone has a lower risk of causing these side effects compared to older antipsychotics. It is not a major concern with lurasidone treatment.
