ATI Capstone Medical Surgical Assessment 2 Quizlet

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority action in the treatment of chest pain in acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain. Aspirin can also be given to reduce clot formation, but nitroglycerin takes precedence in providing immediate relief. Obtaining cardiac enzymes and assessing heart sounds are important steps in the diagnostic process but do not address the immediate need to relieve chest pain and prevent cardiac tissue damage. Therefore, administering sublingual nitroglycerin is the most appropriate initial intervention for a patient presenting with chest pain and possible acute coronary syndrome.

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: Continuous bubbling in the water seal chamber of a chest tube usually indicates an air leak. An air leak can disrupt the negative pressure required for the chest tube to function properly, leading to inadequate drainage and potential complications. A blockage in the chest tube would typically result in decreased or absent drainage rather than continuous bubbling. Normal chest tube function does not involve continuous bubbling in the water seal chamber. Drainage from the chest tube may lead to fluid moving into the drainage system, but it would not cause continuous bubbling in the water seal chamber.

Correct Answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This signifies that air is escaping from the patient's pleural space into the chest tube system rather than being evacuated properly. An air leak can lead to lung collapse or pneumothorax and requires immediate attention. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because continuous bubbling does not indicate normal chest tube function, drainage in the chest tube, or a blocked chest tube.

Correct Answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
