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?
Vasogenic cerebral edema
Osmotic cerebral edema
Cellular cerebral edema
Interstitial cerebral edema
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A Reason:
COPD is a chronic lung condition characterized by airflow limitation that is not fully reversible. Individuals with COPD often have underlying structural lung changes, such as emphysematous bullae or blebs. These areas of weakened lung tissue are prone to rupture, leading to the development of pneumothorax. Additionally, the chronic inflammation and damage to the airways and lung parenchyma in COPD contribute to the development of pneumothorax.
Choice B Reason:
Sarcoidosis is incorrect. Sarcoidosis is a granulomatous disease that primarily affects the lungs and lymph nodes. While it can cause lung damage and lead to pneumothorax, it is less common than COPD as a comorbidity associated with SSP.
Choice C Reason:
Lung cancer is incorrect. Lung cancer can lead to pneumothorax, especially if the tumor erodes into the pleural space. However, SSP is more commonly associated with underlying lung diseases like COPD rather than lung cancer.
Choice D Reason:
Cystic fibrosis is incorrect. Cystic fibrosis is a genetic disorder characterized by abnormal mucus production and impaired clearance in various organs, including the lungs. While individuals with cystic fibrosis are at increased risk of pneumothorax due to underlying lung disease, SSP is less commonly seen in this population compared to COPD.
Correct Answer is ["B","D","E"]
Explanation
Choice A Reason:
Metoprolol is incorrect. Metoprolol is a beta-blocker medication commonly used to treat conditions such as hypertension, angina, and heart failure. However, in the context of neurogenic shock following a spinal cord injury, the use of beta-blockers such as metoprolol is generally contraindicated. Beta-blockers antagonize the effects of sympathetic activation, leading to a reduction in heart rate and myocardial contractility, which can exacerbate hypotension and bradycardia, the hallmarks of neurogenic shock. Therefore, the nurse would not anticipate a prescription for metoprolol in the management of neurogenic shock.
Choice B Reason:
Lactated Ringers intravenous fluid is correct. Fluid resuscitation with isotonic crystalloid solutions such as lactated Ringers is essential to restore intravascular volume and improve perfusion.
Choice C Reason:
Furosemide is incorrect. Furosemide is a loop diuretic medication commonly used to treat conditions such as heart failure, edema, and hypertension by promoting diuresis and reducing fluid volume. However, in the context of neurogenic shock, the use of diuretics such as furosemide is generally not indicated unless there is concurrent volume overload. Neurogenic shock is characterized by hypotension due to vasodilation and decreased systemic vascular resistance, often leading to relative hypovolemia rather than volume overload. Therefore, administering furosemide could further decrease intravascular volume, exacerbating hypotension and compromising perfusion. As a result, the nurse would not anticipate a prescription for furosemide in the management of neurogenic shock.:
Choice D Reason:
Dopamine is correct. Dopamine is a vasopressor medication that acts to increase vascular tone and blood pressure by stimulating alpha-adrenergic receptors. It is commonly used in the management of neurogenic shock to augment blood pressure.
Choice E Reason:
Epinephrine is correct. Epinephrine is a potent vasopressor that acts on both alpha and beta-adrenergic receptors, leading to vasoconstriction and increased cardiac output. It is used in the treatment of refractory hypotension in neurogenic shock.
