After coronary artery bypass graft surgery, a male client is admitted to the coronary care unit. Which nursing diagnosis is of the highest priority?

Correct Answer: B

Rationale: Impaired gas exchange is the highest priority nursing diagnosis because it directly impacts the client's oxygenation. Following coronary artery bypass graft surgery, ensuring adequate oxygen exchange is crucial for the client's recovery. Ineffective breathing pattern, although important, may not be as critical as impaired gas exchange in the immediate postoperative period. Acute pain, while significant, can be managed effectively with appropriate interventions and is not as emergent as addressing impaired gas exchange. Risk for infection is also a valid concern post-surgery, but ensuring optimal gas exchange takes precedence to prevent complications associated with inadequate oxygenation.

Correct Answer: B

Rationale: Intermittent bubbling in the suction control chamber is the correct observation indicating effective functioning of the chest tube. This bubbling signifies that the suction system is working correctly and maintaining the desired negative pressure in the pleural space. Continuous bubbling in the water-seal chamber suggests an air leak, which is not a normal finding. No fluctuation (tidaling) in the water-seal chamber may indicate a blockage or lack of communication between the pleural space and the water-seal, which is not ideal. Drainage of clear, pale yellow fluid from the chest tube is a normal finding, but it does not specifically indicate the effectiveness of the chest tube function.

Correct Answer: B

Rationale: Organizing free community exercise classes is the most likely successful intervention as it provides a structured and accessible opportunity for adults to engage in physical activity. This choice directly offers a practical solution by providing a regular and organized setting for individuals to participate in physical activity. Distributing flyers about the benefits of exercise, while informative, may not lead to actual participation. Partnering with local gyms to offer discounts relies on individuals taking the initiative to sign up for gym memberships, which may not be feasible for everyone. Hosting a health fair with information booths is informative but may not directly address the need for increased physical activity among adults in the community.

Correct Answer: B

Rationale: Sharing personal stories from individuals affected by substance abuse is the most effective approach for engaging the audience. Personal stories evoke emotions, create empathy, and make the impact of substance abuse more relatable and tangible for the audience. This approach helps in fostering a deeper understanding of the real-life consequences of substance abuse on families. The other options, such as showing statistical data (choice A), distributing informational brochures (choice C), and providing a list of treatment centers (choice D), may be informative but may not engage the audience on an emotional level as effectively as personal stories.

Correct Answer: A

Rationale: The correct answer is A. A Milwaukee brace should be worn over a T-shirt for 23 hours a day to reduce friction and chafing of the skin. This ensures that the brace is not directly against the skin, which can cause discomfort and skin irritation. Choice B is incorrect because the brace should typically be worn continuously, even while sleeping, unless otherwise instructed by a healthcare provider. Choice C is incorrect as wearing the brace directly against the skin can lead to skin issues. Choice D is incorrect since the brace should not be removed while eating to maintain the prescribed wear time.
