What is the most likely cause of continuous bubbling in the water seal chamber of a chest tube?

A. An air leak

B. A blockage in the chest tube

C. Normal chest tube function

D. Drainage from the chest tube

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.

What is the initial nursing action for a patient with a chest tube found to have an air leak?

• A. Check the tube connections
• B. Replace the chest tube
• C. Remove and reinsert the chest tube
• D. Document the incident

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.

What is the first intervention for a patient admitted with unstable angina?

• A. Administer nitroglycerin
• B. Obtain cardiac enzymes
• C. Start IV fluids
• D. Monitor for chest pain

Correct Answer: A
Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

A client has a Transient Ischemic Attack (TIA). What should the nurse teach?

• A. Avoid eating within 3 hours of bedtime
• B. Consume liquids between meals
• C. Eat large meals to increase caloric intake
• D. Avoid liquids to prevent aspiration

Correct Answer: A
Rationale: The correct answer is A: Avoid eating within 3 hours of bedtime. For a client with a Transient Ischemic Attack (TIA), it is crucial to avoid eating within 3 hours of bedtime to reduce reflux that can worsen symptoms. Choice B is incorrect because consuming liquids between meals is not specifically related to managing TIA. Choice C is incorrect as eating large meals may not be recommended, especially if the client needs to watch their caloric intake. Choice D is incorrect because avoiding liquids entirely can lead to dehydration and is not a standard recommendation for TIA management.

A client is to undergo a liver biopsy. Which of the following instructions should the nurse provide to the client following the procedure?

• A. Lie on your left side.
• B. Lie on your right side.
• C. Increase your fluid intake.
• D. Decrease your fluid intake.

Correct Answer: B
Rationale: After a liver biopsy, the nurse should instruct the client to lie on the right side. This position helps apply pressure to the biopsy site, promoting hemostasis and reducing the risk of bleeding. Lying on the left side may not provide adequate pressure to the site. Increasing fluid intake is generally beneficial to prevent dehydration and aid in the recovery process, whereas decreasing fluid intake could lead to dehydration and possible complications. Therefore, the correct instruction is to lie on the right side.
