Correct Answer: A

Rationale: When a patient with a chest tube is found to have an air leak, the priority action for the nurse is to check the tube connections. This step helps identify the source of the air leak, which can be caused by loose or disconnected tube connections. Once the source of the leak is identified and addressed, further interventions may be necessary. Replacing or removing and reinserting the chest tube should not be the initial response unless there are specific indications for these actions. Documenting the incident is important but comes after addressing the immediate concern of the air leak.

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate intervention is to tighten the connections of the chest tube system. This action can help resolve an air leak, which is often the cause of continuous bubbling in the water seal chamber. Clamping the chest tube (choice B) is not recommended as it can lead to a dangerous increase in pressure within the chest. Replacing the chest tube (choice C) is not the initial intervention unless there are other indications to do so. Simply monitoring the chest tube (choice D) without taking corrective action will not address the underlying issue of the air leak causing continuous bubbling.

Correct Answer: D

Rationale: In patients with pre-dialysis end-stage kidney disease, it is crucial to limit phosphorus intake to 700mg/day to manage their condition. High phosphorus levels can lead to complications such as bone and heart problems. Limiting protein intake is essential in later stages of kidney disease, particularly in dialysis patients to reduce the buildup of waste products. While limiting potassium and restricting sodium intake are also important in kidney disease management, the priority for a patient with pre-dialysis end-stage kidney disease is to control phosphorus levels.

Correct Answer: A

Rationale: When a nurse administers insulin for a misread glucose level, they should monitor for hypoglycemia. Insulin lowers blood sugar levels, so the patient may experience hypoglycemia if given insulin unnecessarily. Monitoring for hypoglycemia involves observing for symptoms such as shakiness, sweating, dizziness, confusion, and palpitations. Choices B and C are incorrect because administering insulin for a misread glucose level would lower blood sugar levels, resulting in hypoglycemia, not hyperglycemia or hyperkalemia. Choice D is not the immediate priority; the focus should be on patient safety and monitoring for potential adverse effects of the unnecessary insulin.

Correct Answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is a fast-acting bronchodilator that helps relieve wheezing by relaxing the muscles in the airways, making it the first-line treatment for wheezing caused by bronchospasms in allergic reactions. Methylprednisolone (Choice B) is a corticosteroid used for its anti-inflammatory properties and is typically given after bronchodilators. Cromolyn (Choice C) is a mast cell stabilizer that is used for the prevention of asthma symptoms, not for immediate relief. Aminophylline (Choice D) is a bronchodilator that is less commonly used nowadays due to its narrow therapeutic window and potential for toxicity.
