1. What is the first action when continuous bubbling is observed 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 system
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the first action should be to tighten the connections of the chest tube system. This step is crucial as it can often resolve an air leak causing continuous bubbling. Clamping the chest tube or replacing the chest tube system would not address the underlying issue of loose connections and may not be necessary. Continuing to monitor the chest tube without taking corrective action may lead to complications if the air leak is not addressed promptly.

2. What is the priority nursing action when a patient with chest pain presents with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Obtain IV access
• C. Check the patient's cardiac enzymes
• D. Administer aspirin

Correct answer: A

Rationale: The priority nursing action when a patient with chest pain presents with possible acute coronary syndrome is to administer sublingual nitroglycerin. Sublingual nitroglycerin helps dilate blood vessels, reducing cardiac workload, and improving blood supply to the heart muscle, thus relieving pain and enhancing blood flow to the heart. While obtaining IV access is important for administering medications and fluids, it is not the priority over addressing pain and improving blood flow. Checking the patient's cardiac enzymes is crucial for diagnosis and ongoing management but not the immediate priority when the patient is in pain. Administering aspirin is also a vital intervention in acute coronary syndrome, but in this scenario, it is not the priority action compared to providing immediate pain relief and enhancing blood flow to the heart.

3. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

4. What teaching should be provided to a patient after cataract surgery?

• A. Avoid NSAIDs
• B. Avoid bright lights
• C. Wear dark glasses while outdoors
• D. Use warm compresses

Correct answer: A

Rationale: The correct teaching to provide to a patient after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to reduce the risk of bleeding post-surgery. Choices B, C, and D are not directly related to post-cataract surgery care. Avoiding bright lights and wearing dark glasses while outdoors may be beneficial for eye comfort but are not specific postoperative instructions. Using warm compresses is also not a standard teaching after cataract surgery.

5. What medication should be administered first for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Methylprednisolone IV
• D. Aminophylline IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.
