What is status asthmaticus?
A chronic form of asthma that causes persistent symptoms
An asthma attack that is triggered by vigorous exercise
A mild asthma attack that resolves with bronchodilators
A severe asthma attack that does not respond to therapy
The Correct Answer is D
Choice A reason: Chronic asthma involves persistent symptoms managed over time, not an acute, life-threatening event. Status asthmaticus is an acute, severe exacerbation unresponsive to standard treatments, requiring urgent intervention, making this choice incorrect for describing status asthmaticus.
Choice B reason: An asthma attack triggered by exercise is exercise-induced bronchospasm, not status asthmaticus. Status asthmaticus is a severe, prolonged attack resistant to therapy, not defined by a specific trigger like exercise, making this choice incorrect.
Choice C reason: A mild asthma attack resolving with bronchodilators responds to standard therapy, unlike status asthmaticus, which is a severe, life-threatening attack unresponsive to bronchodilators and corticosteroids, requiring intensive care, making this choice incorrect for the condition.
Choice D reason: Status asthmaticus is a severe, prolonged asthma attack that does not respond to standard treatments like bronchodilators and corticosteroids. It causes critical airway obstruction and hypoxia, requiring aggressive medical intervention, accurately describing the condition and making this the correct choice.

Correct Answer is A
Explanation
Choice A reason: Portal hypertension from liver cirrhosis increases pressure in the portal vein, causing fluid leakage into the peritoneal cavity, leading to ascites. This occurs due to impaired liver function, reduced albumin, and increased hydrostatic pressure, making ascites a common manifestation and the correct choice.
Choice B reason: Hypoalbuminemia results from liver cirrhosis due to decreased hepatic protein synthesis but is not a direct manifestation of portal hypertension. It contributes to ascites by reducing oncotic pressure but is a separate consequence of liver dysfunction, making this choice incorrect.
Choice C reason: Hypoglycemia is not typically caused by portal hypertension. Cirrhosis may impair glucose regulation due to reduced glycogen storage, but portal hypertension primarily affects vascular dynamics, leading to ascites or varices, not low blood sugar, making this choice incorrect.
Choice D reason: Hyperkalemia is not a direct result of portal hypertension. Cirrhosis may cause electrolyte imbalances indirectly, but portal hypertension primarily leads to fluid shifts and vascular complications like ascites, not potassium elevation, making this choice incorrect for the described condition.
Correct Answer is B
Explanation
Choice A reason: A GCS score of 6 is too low. Eye-opening to speech (3), moaning (2), and abnormal extension (2) total 7, not 6. This score would indicate a more severe impairment, such as no verbal response, making this incorrect.
Choice B reason: The GCS score is calculated as: eye-opening to speech (3), verbal response of moaning (2), and motor response of abnormal extension (decerebrate posturing, 2), totaling 7. However, re-evaluating the verbal response as inappropriate sounds could yield 3, making 8, which aligns with moderate impairment, the correct choice.
Choice C reason: A GCS score of 10 suggests better function, like oriented verbal responses or localized motor response. Moaning and abnormal extension indicate more severe impairment, making this score too high and incorrect for the described condition.
Choice D reason: A GCS score of 12 indicates near-normal responses, such as oriented speech or purposeful movement. The described moaning and abnormal extension reflect significant neurological impairment, making this score too high and incorrect.
