A nurse is caring for a client admitted with meningitis.
The student nurse asks, “I know that the client has a lot of edema in the brain, but what causes it?” Which of the following responses from the nurse best answers the student’s querry
Cerebral edema is caused by osmotic cerebral edema.
Cerebral edema is caused by whole body inflammation which affects the brain the most.
Cerebral edema is caused by cerebrospinal fluid flowing from the intraventricular space to the interstitial area of the brain.
Cerebral edema is caused by the by-products of the pathogen that causes the meningitis.
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A rationale
Maintaining the head of the bed between 30 and 45 degrees is a common intervention for a patient at risk of cerebral aneurysm rupture. This position can help reduce intracranial pressure and promote venous drainage from the brain.
Choice B rationale
Administering hypotonic intravenous solutions is not typically recommended for patients at risk of cerebral aneurysm rupture. Hypotonic solutions can lead to cerebral edema, which can increase intracranial pressure and potentially contribute to aneurysm rupture.
Choice C rationale
Keeping lights at a medium level in the evening is not a specific intervention for patients at risk of cerebral aneurysm rupture. While maintaining a comfortable and restful environment is important, there’s no evidence to suggest that the level of lighting has a direct impact on the risk of aneurysm rupture.
Choice D rationale
Repositioning the patient every shift is a standard nursing intervention to prevent pressure ulcers and promote comfort. However, it is not a specific intervention for patients at risk of cerebral aneurysm rupture.
Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
Hyponatremia, or low sodium levels, is not typically a symptom of degenerative disc disease. It can be caused by a variety of conditions, but it is not directly linked to degenerative disc disease.
Choice B rationale
Paresthesia, or abnormal sensations such as tingling or prickling, can develop with degenerative disc disease. This is due to the fact that degenerative changes can lead to nerve compression, which can cause these sensations.
Choice C rationale
Foot drop, a gait abnormality, can be a symptom of degenerative disc disease. It can occur if the disease process affects the nerves that control the muscles involved in lifting the foot.
Choice D rationale
Intermittent pain is a common symptom of degenerative disc disease. The pain can vary in intensity and may be worse with certain activities or positions.
Choice E rationale
Hyperreflexia, or overactive reflexes, is not typically a symptom of degenerative disc disease. It is more commonly associated with conditions that affect the upper motor neurons.
