A nurse is caring for a client who is receiving mechanical ventilation. Which of the following actions should the nurse implement to decrease the client's risk for ventilator-associated pneumonia (VAP)? (Select all that apply.).

Choice A rationale:

The nurse should not advise the client with multiple sclerosis to schedule all physical activities for the morning hours. While some individuals with multiple sclerosis may experience increased fatigue later in the day, the best approach is to encourage the client to schedule activities at times when they feel the most energetic and to balance physical activity with rest throughout the day.

Choice B rationale:

Monitoring blood pressure is essential while taking fingolimod, a medication used to treat multiple sclerosis, as it can cause a transient decrease in heart rate and blood pressure.

Therefore, the nurse should include this statement in the teaching to ensure the client's safety and early detection of any issues.

Choice C rationale:

This is the correct statement to include in the teaching. Clients with multiple sclerosis should avoid rigorous activities that increase body temperature, as this can worsen their symptoms due to the sensitivity of demyelinated nerves to heat. Activities such as hot baths or engaging in strenuous exercise in hot weather should be avoided.

Choice D rationale:

Corticosteroids are not typically used as a long-term treatment for multiple sclerosis. Instead, they are used for short courses during exacerbations to reduce inflammation and manage acute symptoms. Long-term use of corticosteroids can lead to significant adverse effects, so the nurse should not include this statement in the teaching.

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.
