A nurse is caring for a patient experiencing acute pain following a knee injury.
The nurse is educating the patient about pain management strategies to use at home.Which of the following non-pharmacological methods of pain relief should the nurse include in their teaching?

Choice A rationale
Assessing muscle strength is important after a fall as it can help determine if the fall was due to muscle weakness or other neurological issues.
Choice B rationale
Checking for facial symmetry is crucial as asymmetry may indicate a stroke or other serious neurological condition.
Choice C rationale
While checking peripheral pulses is important in general, it may not be the top priority in this case unless there is a specific reason to suspect circulatory issues.
Choice D rationale
Evaluating vision changes is important as sudden vision loss or changes could indicate a serious condition such as a stroke.
Choice E rationale
Checking for aphasia, or difficulty with language, is crucial as it can be a sign of a stroke or other serious neurological condition.
Choice F rationale
Asking about smoking history may not be a priority in the immediate assessment of a patient who has just fallen.

Choice A rationale
Osmotic cerebral edema is a condition where water moves from the blood vessels into the brain due to changes in the concentration of particles in the blood. However, this is not the primary cause of cerebral edema in meningitis.
Choice B rationale

While inflammation can contribute to cerebral edema, it is not specific to the brain and does not affect the brain the most. In meningitis, the inflammation is primarily in the meninges, the membranes that cover the brain, and not the whole body.
Choice C rationale
Cerebrospinal fluid (CSF) does flow from the intraventricular space to the interstitial area of the brain, but this is a normal process and does not cause cerebral edema. In meningitis, the inflammation of the meninges can disrupt the normal flow and absorption of CSF, leading to an accumulation of fluid and increased intracranial pressure.
Choice D rationale
In meningitis, the inflammation and immune response to the infection can lead to an increase in the permeability of the blood-brain barrier. This allows fluid and immune cells to enter the brain tissue, leading to cerebral edema. Additionally, the by-products of the pathogen that causes meningitis can directly damage the brain tissue and contribute to the edema.
