1. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blockage in the chest tube
• C. Normal chest tube function
• D. Malfunction in the drainage system

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This bubbling occurs when air is escaping through the tube and entering the water seal chamber. Choice B, a blockage in the chest tube, is incorrect as continuous bubbling does not suggest a blockage. Choice C, normal chest tube function, is incorrect because continuous bubbling is not an expected finding in a properly functioning chest tube. Choice D, a malfunction in the drainage system, is incorrect as continuous bubbling specifically points towards an air leak, not a general malfunction.

2. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

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.

3. What is the priority intervention for a patient with unstable angina?

• A. Administer nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

4. What is the priority intervention when continuous bubbling is observed in the water seal chamber of a chest tube?

• A. Check for an air leak
• B. Continue monitoring as it is not normal
• C. Replace the chest tube system
• D. Tighten the tube connections

Correct answer: A

Rationale: The correct answer is to 'Check for an air leak.' Continuous bubbling in the water seal chamber of a chest tube indicates an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Checking for an air leak is crucial to prevent respiratory complications. Choice B is incorrect because continuous bubbling is not normal and requires immediate intervention to address the air leak. Choice C is incorrect as replacing the entire chest tube system is not the initial priority when an air leak is suspected. Choice D is incorrect because tightening tube connections may not address the underlying issue of an air leak and should not be the initial action taken in this situation.

5. A nurse is teaching a client who has type 1 DM about hypoglycemia. Which of the following statements by the client indicates an understanding of the teaching?

• A. Exercise reduces the risk for hypoglycemia.
• B. I can skip my insulin when I don't eat.
• C. I can drink 4 oz of soda if my blood sugar is low.
• D. Diabetic pills don't cause hypoglycemia; only insulin does.

Correct answer: C

Rationale: The client can correct any development of hypoglycemia with a quick intake of glucose. The client should have 15 g carbohydrates on hand to treat hypoglycemic episodes, like 4 oz of regular soda.
