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 precaution should be advised to a patient following a cataract surgery?

• A. Wear dark glasses while outdoors
• B. Avoid NSAIDs
• C. Use warm compresses
• D. Apply cold packs

Correct answer: A

Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.

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

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

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This bubbling occurs when air leaks from the patient's pleural space into the chest tube system. It is essential to address this issue promptly to prevent complications like a pneumothorax. Choices B, C, and D are incorrect because continuous bubbling in the water seal chamber is not indicative of normal chest tube function, a blockage in the chest tube, or a malfunction in the drainage system.

4. A client is being taught about fecal occult blood testing (FOBT) for colorectal cancer screening. Which of the following statements should the nurse include in the teaching?

• A. Your provider will use a stool sample obtained during a digital rectal examination to perform the test.
• B. Your provider will recommend a stimulant laxative before the test to empty the bowel.
• C. You should start annual fecal occult blood testing for colorectal cancer screening at the age of 40.
• D. You should avoid corticosteroids before the test.

Correct answer: D

Rationale: The correct answer is D because the nurse should advise the client to avoid corticosteroids, anti-inflammatory medications, and vitamin C before fecal occult blood testing to prevent false-positive results. Choice A is incorrect as stool samples for FOBT are usually collected using a kit at home. Choice B is incorrect because stimulant laxatives are not typically used before FOBT. Choice C is incorrect as guidelines recommend starting colorectal cancer screening at the age of 50, not 40.

5. What should a healthcare professional monitor in a patient receiving insulin who is at risk for hypoglycemia?

• A. Monitor blood glucose levels
• B. Monitor for respiratory distress
• C. Monitor for muscle weakness
• D. Monitor for hyperkalemia

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.
