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 dietary changes should a patient with GERD make to manage their symptoms?

• A. Avoid mint and spicy foods
• B. Eat large, frequent meals
• C. Consume liquids with meals
• D. Eat small, frequent meals

Correct answer: A

Rationale: The correct answer is A: Avoid mint and spicy foods. Patients with GERD should avoid foods like mint and spicy dishes as they can trigger symptoms by increasing gastric acid secretion. Choices B, C, and D are incorrect. Eating large, frequent meals can exacerbate GERD symptoms by putting more pressure on the lower esophageal sphincter, consuming liquids with meals can lead to increased reflux, and eating small, frequent meals is the recommended approach to reduce symptoms and manage GERD.

3. What intervention is needed when continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Replace the chest tube
• D. Continue monitoring the chest tube

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.

4. A nurse is providing discharge teaching for a client who has COPD about nutrition. Which of the following instructions should the nurse include?

• A. Eat three large meals daily
• B. Consume high-calorie foods
• C. Limit caffeinated drinks to two per day
• D. Drink fluids during meal time

Correct answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.

5. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.
