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.

Correct Answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the correct intervention is to tighten the connections of the chest tube system. This can help resolve an air leak that is causing the continuous bubbling. Clamping the chest tube or replacing the entire chest tube system are not appropriate interventions in this scenario. Clamping the tube can lead to a dangerous buildup of pressure, while replacing the chest tube system may not be necessary if the issue can be resolved by simply tightening the connections. Continuing to monitor the chest tube without taking corrective action may lead to complications associated with the air leak.

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.

Correct Answer: A

Rationale: The correct teaching to provide to a patient following cataract surgery is to avoid NSAIDs. NSAIDs should be avoided post-cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses outdoors, is important to protect the eyes from bright light but is not directly related to medication use. Choice C, stating that creamy white drainage is normal, is incorrect as drainage should be monitored for excessive redness, swelling, or pain. Choice D, avoiding alcohol, is not a direct post-cataract surgery teaching point related to medication use.
