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:
(Fluticasone) Fluticasone is a corticosteroid inhaler used for the long-term management of asthma symptoms and prevention of asthma attacks. It is not suitable for treating acute asthma
attacks. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
Choice B rationale:
(Albuterol) Albuterol is a short-acting beta-agonist bronchodilator and the preferred medication for relieving acute asthma symptoms and treating asthma attacks. It works by quickly relaxing the airway muscles, making it easier to breathe during an asthma attack. Therefore, this is the correct choice for medications to treat an acute asthma attack.
Choice C rationale:
(Salmeterol) Salmeterol is a long-acting beta-agonist bronchodilator used for the prevention of asthma symptoms but should not be used for treating acute asthma attacks. It has a slower onset of action compared to short-acting beta-agonists like albuterol. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
Choice D rationale:
(Beclomethasone) Beclomethasone is a corticosteroid inhaler used for long-term asthma management and prevention of asthma symptoms but is not appropriate for treating acute asthma attacks. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
Correct Answer is D
Explanation
Choice A rationale:
Severe headache can be a symptom of a subdural hematoma, but it is not the earliest manifestation of a change in neurological status. Other symptoms may appear before a severe headache, such as an altered level of consciousness.
Choice B rationale:
Bradycardia can occur with a subdural hematoma, especially as intracranial pressure increases. However, it is not the earliest manifestation of a change in neurological status. Changes in heart rate may occur later in the progression of the condition.
Choice C rationale:
Widened pulse pressure can also occur in patients with a subdural hematoma due to increased intracranial pressure. However, it is not the earliest manifestation of a change in neurological status. Other neurological signs would likely appear before changes in pulse pressure are evident.
Choice D rationale:
Change in level of consciousness is the earliest manifestation of a change in neurological status with a subdural hematoma. As intracranial pressure increases, the brain's functioning can be affected, leading to alterations in consciousness, ranging from mild confusion to unconsciousness.
