A nurse is caring for a group of clients in a medical unit. Which of the following clients is at the highest risk for developing osmotic cerebral edema?
A client with a decreased potassium level
A client with a decreased serum glucose
A client with an increased hemoglobin A1C
A client with an increased creatinine level
None
None
The Correct Answer is B
Choice A Reason:
A client with a decreased potassium level is incorrect. Hypokalemia (decreased potassium level) can cause various neurological symptoms, but it doesn't directly lead to osmotic cerebral edema.
Choice B Reason:
When plasma glucose levels are rapidly lowered, an osmotic gradient develops between the brain and plasma, which can lead to cerebral edema. Brain cells pull water from the plasma, resulting in widespread edema.
Choice C Reason:
While HbA1c is an important marker of diabetes control and may indicate poor long-term management, it does not directly relate to the acute metabolic derangements (e.g., rapid osmotic shifts, severity of acidosis) that predispose to cerebral edema in DKA.
Choice D Reason:
A client with an increased creatinine level is incorrect. Elevated creatinine levels typically indicate kidney dysfunction or dehydration, but they don't directly cause osmotic cerebral edema.

Correct Answer is C
Explanation
A.Osmotic edema refers to fluid shifts due to changes in osmotic gradients (as seen in conditions like hyponatremia), not the inflammatory process of meningitis.
B.While inflammation is a key part of the body's response in meningitis, the edema is not a result of generalized whole-body inflammation. The edema is more directly linked to local inflammatory reactions in the brain triggered by the pathogen’s by-products.
C.Bacterial cell walls, endotoxins, and other components released by the bacteria directly stimulate inflammation, causing the breakdown of the BBB and allowing fluid and inflammatory cells to leak into the brain tissue.
D.This description is more aligned with the pathophysiology of conditions like hydrocephalus rather than meningitis. In meningitis, cerebral edema is primarily due to the inflammatory response, not abnormal CSF flow.
Correct Answer is ["A","B","C","D","E","F"]
Explanation
Choice A Reason:
Refraining from climbing ladders is appropriate. Climbing ladders involves a risk of falling, which can be particularly hazardous for individuals with epilepsy. Seizures can occur unexpectedly and may cause loss of muscle control or consciousness, increasing the risk of falls from heights such as ladders. Falling from a ladder during a seizure can result in serious injuries, including head trauma, fractures, or other injuries from impact. Advising the client to refrain from climbing ladders helps mitigate the risk of falls and associated injuries during a seizure episode, promoting their safety and well-being.
Choice B Reason:
Do not go swimming without a partner is inappropriate. Swimming alone can be dangerous for individuals with epilepsy as they may be at risk of drowning if they experience a seizure while in the water. Having a swimming partner can provide assistance and ensure safety in case of a seizure.
Choice C Reason:
Refraining from driving unless seizure-free for 3 months is appropriate. Driving restrictions are often recommended for individuals with epilepsy to minimize the risk of accidents caused by seizures. Many jurisdictions require individuals with epilepsy to be seizure-free for a certain period, typically around 3 to 6 months, before resuming driving.
Choice D Reason:
Avoiding using power tools is appropriate. Operating power tools or machinery can be hazardous if a seizure occurs, potentially leading to serious injuries. Therefore, individuals with epilepsy should avoid using power tools to reduce the risk of accidents during a seizure.
Choice E Reason:
Placing client on the floor when having a seizure is appropriate. Placing the client on the floor during a seizure helps prevent injury from falls. It is safer to have the individual lie down on a flat surface to reduce the risk of head injury or other trauma during the seizure.
Choice F Reason:
Placing client on their back when they are recovering from a seizure appropriate. Placing the client on their back after a seizure helps maintain an open airway and facilitates recovery. This position allows for proper breathing and circulation while monitoring the individual's condition.
