A nurse is teaching a student about cerebral edema. The student nurse asks, "What type of cerebral edema is associated with a client who has a stroke?" Which of the following is the best response from the nurse?

Choice A Reason:

MS hug is appropriate. The "MS hug" is a colloquial term used to describe a sensation of tightness, pressure, or squeezing around the torso or chest area experienced by some individuals with multiple sclerosis (MS). It is caused by spasms or contractions of the intercostal muscles (muscles between the ribs) or the diaphragm due to lesions in the spinal cord disrupting nerve signals. This sensation can be uncomfortable or painful for the individual.

Choice B Reason:

Lhermitte's sign is inappropriate. Lhermitte's sign is a common symptom experienced by individuals with MS but it presents differently. It is characterized by an electric shock-like sensation that radiates down the spine and into the limbs, typically triggered by flexing the neck forward. It is caused by damage to the spinal cord's myelin sheath, leading to abnormal nerve signal transmission.

Choice C Reason:

Paroxysmal spasms is inappropriate. Paroxysmal spasms are sudden, involuntary muscle contractions or jerking movements that can occur in various parts of the body. While spasms are common in MS, they are not specifically associated with the sensation of tightness around the torso as described in the scenario.

Choice D Reason:

Trigeminal neuralgia is inappropriate. Trigeminal neuralgia is a condition characterized by sudden, severe facial pain often described as stabbing or electric shock-like. It is caused by irritation or damage to the trigeminal nerve, which is responsible for facial sensation. While individuals with MS may experience trigeminal neuralgia, it typically does not present with a tightening feeling around the torso.

Choice A Reason:

Vasogenic cerebral edema is appropriate response. Vasogenic cerebral edema occurs due to disruption of the blood-brain barrier (BBB), leading to leakage of fluid and proteins from the blood vessels into the brain parenchyma. This type of cerebral edema is commonly associated with conditions such as brain tumors, abscesses, and ischemic stroke.

Choice B Reason:

Osmotic cerebral edema is inappropriate response. Osmotic cerebral edema occurs when there is an imbalance of osmotic forces across the blood-brain barrier, leading to the movement of water into the brain cells. This type of cerebral edema can result from conditions such as hyponatremia or the administration of hypertonic solutions.

Choice C Reason:

Cellular cerebral edema is inappropriate response. Cellular cerebral edema involves the swelling of brain cells (neurons and glial cells) due to various insults, such as ischemia, hypoxia, or metabolic disturbances. This type of cerebral edema can occur in conditions such as ischemic stroke or traumatic brain injury.

Choice D Reason:

Interstitial cerebral edema is incorrect response. Interstitial cerebral edema involves the accumulation of fluid within the interstitial spaces of the brain tissue. This type of cerebral edema can occur in conditions such as hydrocephalus, where there is obstruction of cerebrospinal fluid (CSF) flow.
