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:
Preparing an endotracheal tube for intubation is not the first action the nurse should take in this situation. Intubation is an invasive procedure and should be reserved for cases where other, less invasive methods of airway management have failed.
Choice B rationale:
Inserting a plastic oral airway may help maintain the airway in some situations, but it is not the first action to take when the client's airway is obstructing and their oxygen saturation is low.
Choice C rationale:
Providing oxygen using a manual resuscitation bag (bag-valve-mask device) is the correct first action. This allows the nurse to manually assist the client's breathing and deliver oxygen more effectively than just providing supplemental oxygen through a nasal cannula or face mask.
Choice D rationale:
Performing a head tilt with a chin-lift is a basic airway maneuver, but it may not be sufficient in this situation, especially if the airway is completely obstructed. Providing oxygen with a manual resuscitation bag takes precedence.
Correct Answer is C
Explanation
Choice A rationale:
The nurse should not cross the client's legs when sitting in the recliner following a total left hip arthroplasty. Crossing the legs can put strain on the operative hip and may increase the risk of dislocation or other complications.
Choice B rationale:
Providing a heating pad to the operative hip is not recommended. Heat can increase blood flow to the area and may lead to increased swelling and potential complications in the postoperative period.
Choice C rationale:
Placing a pillow between the legs when turning the client to their side is the correct action. This technique is known as the "abduction pillow”. or "wedge pillow.”. It helps maintain proper hip alignment and prevents the operated leg from crossing the midline, reducing the risk of dislocation and promoting healing.
Choice D rationale:
Having the client lean forward when assisting them out of the bed is not appropriate after a total left hip arthroplasty. Leaning forward can put strain on the hip joint and increase the risk of injury.
