Correct Answer: A

Rationale: The correct answer is to 'Check for an air leak.' Continuous bubbling in the water seal chamber of a chest tube indicates an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Checking for an air leak is crucial to prevent respiratory complications. Choice B is incorrect because continuous bubbling is not normal and requires immediate intervention to address the air leak. Choice C is incorrect as replacing the entire chest tube system is not the initial priority when an air leak is suspected. Choice D is incorrect because tightening tube connections may not address the underlying issue of an air leak and should not be the initial action taken in this situation.

Correct Answer: A

Rationale: The correct action to take when a patient reports cramping during enema administration is to lower the height of the solution container. Lowering the height reduces the pressure and speed of the solution entering the rectum, alleviating cramping. Increasing the flow of the enema solution (Choice B) can worsen the discomfort. Stopping the procedure and removing the tubing (Choice C) is not necessary unless there are severe complications. Continuing the enema at a slower rate (Choice D) may not effectively address the immediate cramping issue and could still cause discomfort to the patient.

Correct Answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Administering insulin based on a misread glucose level can lead to hypoglycemia. Monitoring for hypoglycemia is crucial as it is a potential adverse effect of the insulin administration. Administering glucose IV (Choice B) is not the priority as there is no indication of hypoglycemia yet. Documenting the incident (Choice C) is important but not the immediate priority over patient safety. Monitoring for hyperglycemia (Choice D) is not the priority after administering insulin in response to a misread glucose level.

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 acts quickly to open the airways by relaxing the muscles in the air passages. Cromolyn (Choice B) is used for asthma prevention rather than acute wheezing. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in the setting of an allergic reaction.

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.
