Correct Answer: B

Rationale: Intermittent bubbling in the suction control chamber is the correct observation indicating effective functioning of the chest tube. This bubbling signifies that the suction system is working correctly and maintaining the desired negative pressure in the pleural space. Continuous bubbling in the water-seal chamber suggests an air leak, which is not a normal finding. No fluctuation (tidaling) in the water-seal chamber may indicate a blockage or lack of communication between the pleural space and the water-seal, which is not ideal. Drainage of clear, pale yellow fluid from the chest tube is a normal finding, but it does not specifically indicate the effectiveness of the chest tube function.

Rationale: Difficulty speaking is a classic symptom of stroke, suggesting a potential blockage of blood flow to the brain. Prompt intervention is crucial to minimize brain damage. Elevated blood pressure (Choice A) may need management but is not the most urgent concern in this scenario. A blood glucose level of 180 mg/dL (Choice B) is slightly elevated but does not require immediate intervention for a suspected stroke. A temperature of 99.8°F (37.7°C) (Choice D) is within normal range and not a critical finding in this context.
