What should be done when continuous bubbling is observed in the chest tube water seal chamber?

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate action is to tighten the connections of the chest tube system. This may resolve an air leak that is causing the continuous bubbling. Option B, replacing the chest tube system, is not the initial step to take and is considered more invasive. Clamping the chest tube (option C) can lead to complications and should not be done unless instructed by a healthcare provider. Continuing to monitor the chest tube (option D) without taking any corrective action may delay necessary interventions.

Correct Answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

Correct Answer: A

Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.

Correct Answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the solution container. This adjustment can help alleviate the cramping by reducing the speed and pressure of the solution entering the colon. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in extreme cases but is not the initial step. Continuing the enema at a slower rate (Choice D) may not effectively address the cramping, making it less optimal than lowering the height of the solution container.

Correct Answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. Mint and spicy foods can aggravate GERD symptoms by relaxing the lower esophageal sphincter and increasing stomach acid production, leading to acid reflux. Choices B, C, and D are incorrect. Eating large meals before bedtime can worsen GERD symptoms as lying down can promote acid reflux. Consuming liquids with meals can also exacerbate GERD by increasing stomach distension and pressure on the lower esophageal sphincter. Eating three large meals per day can overload the stomach and trigger acid reflux episodes in patients with GERD.
