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 step helps address an air leak in the system, which could compromise its effectiveness. Choice B (Replace the chest tube system) is not the initial step and may be unnecessary if the issue can be resolved by tightening connections. Choice C (Clamp the chest tube) is incorrect as clamping the chest tube could lead to a dangerous increase in pressure within the system. Choice D (Continue monitoring the chest tube) is also not the best immediate action to take when continuous bubbling is present, as prompt intervention is needed to prevent complications.

Correct Answer: A

Rationale: The priority nursing action when a patient with chest pain presents with possible acute coronary syndrome is to administer sublingual nitroglycerin. Sublingual nitroglycerin helps dilate blood vessels, reducing cardiac workload, and improving blood supply to the heart muscle, thus relieving pain and enhancing blood flow to the heart. While obtaining IV access is important for administering medications and fluids, it is not the priority over addressing pain and improving blood flow. Checking the patient's cardiac enzymes is crucial for diagnosis and ongoing management but not the immediate priority when the patient is in pain. Administering aspirin is also a vital intervention in acute coronary syndrome, but in this scenario, it is not the priority action compared to providing immediate pain relief and enhancing blood flow to the heart.

Correct Answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. A thrombotic stroke is characterized by a gradual onset of symptoms due to interrupted blood flow in the brain. This interruption results in manifestations such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache, confusion, seizures, and convulsions are more commonly associated with conditions other than thrombotic strokes.

Correct Answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. In a thrombotic stroke, a blood clot forms in an artery supplying blood to the brain, leading to reduced blood flow to a specific area of the brain. This results in a gradual onset of neurological deficits, such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache and vomiting, and loss of sensation in the affected limb are more commonly associated with other types of strokes or medical conditions, not specifically thrombotic strokes. Thrombotic strokes typically present with gradual symptoms due to the gradual blockage of blood flow, leading to a progressive neurological deficit.

Correct Answer: A

Rationale: Monitoring blood glucose levels is crucial in patients receiving insulin who are at risk for hypoglycemia. Insulin can lower blood sugar levels, potentially leading to hypoglycemia, which can be harmful if not promptly recognized and managed. Checking blood glucose levels allows for early detection of low blood sugar levels, enabling timely interventions to prevent complications. Choices B, C, and D are incorrect as they do not directly relate to monitoring for hypoglycemia in patients receiving insulin.
