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:
Administering furosemide may be appropriate for managing ascites, but it is not directly related to preventing complications. Furosemide is a diuretic that helps reduce fluid retention but does not address other potential complications of liver cirrhosis.
Choice B rationale:
Weighing the client weekly is essential to monitor changes in body weight and fluid status, which is crucial in detecting worsening ascites or fluid retention. Sudden weight gain could indicate an exacerbation of ascites or other complications, warranting timely intervention.
Choice C rationale:
Offering the client a high-sodium diet is contraindicated in managing ascites. A high-sodium diet would lead to increased fluid retention and worsen the ascites, potentially exacerbating the client's condition and increasing the risk of complications.
Choice D rationale:
Administering heparin is not relevant to preventing complications in a client with liver cirrhosis and abdominal ascites. Heparin is an anticoagulant, and its use is not indicated for this particular condition.
Correct Answer is A
Explanation
Choice A rationale:
The nurse's first priority in this situation should be to close the pinch clamp on the central venous catheter (CVC). This will prevent air from entering the client's vascular system and causing an air embolism, which can lead to serious complications. Once the clamp is closed, the nurse can then proceed with further assessments and interventions.
Choice B rationale:
Obtaining a prescription for stat ABGS (Arterial Blood Gas Studies) is not the first action the nurse should take in this situation. While ABGS may be relevant later to assess the client's respiratory status, the immediate concern is to prevent air embolism by closing the disconnected IV tubing.
Choice C rationale:
Placing the client in the left Trendelenburg position is not the first priority in this situation. The Trendelenburg position is used to increase venous return and is typically indicated in cases of hypotension or shock. Closing the clamp to prevent an air embolism should be the nurse's initial action.
Choice D rationale:
Checking the tubing for the placement of a locking adaptor is not the first action the nurse should take. While it is essential to ensure that the IV tubing is properly connected and secured, preventing the air from entering the CVC should take precedence in this urgent situation.
