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
Choice A rationale:
Providing pin care when the client is 4 hours postoperative is not appropriate. The client has just undergone skeletal traction placement, and pin care is usually initiated after 24 hours to allow for initial wound healing.
Choice B rationale:
Removing the weights from the traction while repositioning the client in bed is unsafe and not recommended. The weights should remain in place to provide continuous traction and alignment for the fractured hip.
Choice C rationale:
Assessing the client's circulation every 4 hours is essential to monitor for any signs of impaired circulation, such as swelling, pallor, or decreased pulses. Early detection of circulatory compromise is critical to prevent complications like compartment syndrome.
Choice D rationale:
Requesting the client to perform ankle exercises on the affected extremity is not appropriate after skeletal traction placement. Ankle exercises could disrupt traction and hinder the healing process of the fractured hip.
Correct Answer is B
Explanation
Choice A rationale:
An INR (International Normalized Ratio) of 0.8 is within the normal range for someone not on anticoagulation therapy. The aPTT (activated partial thromboplastin time) of 85 seconds is prolonged, but it is not a reason to withhold heparin in itself. Therefore, the nurse should not withhold the medication for these values.
Choice B rationale:
An INR of 2 indicates the client's blood is taking twice as long to clot compared to the average, which can increase the risk of bleeding. The aPTT of 60 seconds is within the normal range. However, the elevated INR suggests the client might be overly anticoagulated, so the nurse should withhold the medication and notify the provider.
