Correct Answer: A

Rationale: In a closed chest drainage system, slow, steady bubbling in the suction control chamber is an expected finding, indicating proper functioning of the system. There is no immediate need for intervention as this indicates the system is working as intended. The nurse should continue to monitor the client's respiratory status for any signs of distress or changes. Checking tubing connections for leaks or clamping the chest tube are unnecessary actions based on the information provided. Checking the suction control outlet on the wall is also not indicated in this scenario.

Correct Answer: A

Rationale: When admitting a client with active tuberculosis, it is crucial to assign them to a room with air exhaust directly to the outdoor environment to prevent the spread of infectious particles to other patients and healthcare workers. This setup helps in reducing the risk of transmission within the healthcare facility. Placing the client in a room with another nonsurgical client or in the ICU may increase the chances of spreading the infection. Additionally, placing the client in a room within view of the nurses' station does not address the need for proper ventilation to minimize transmission of tuberculosis.

Correct Answer: C

Rationale: Chronic bronchitis is often linked to smoking. Smoking cessation is the most effective preventive measure to reduce the risk of developing chronic bronchitis. Smoking damages the airways and leads to inflammation, making individuals more susceptible to chronic bronchitis. While maintaining an ideal weight, getting an annual influenza vaccine, and engaging in regular moderate exercise are beneficial for overall health, the most crucial intervention to prevent chronic bronchitis is quitting smoking.

Correct Answer: B

Rationale: In the postoperative period following CABG surgery, deep breathing exercises are essential to prevent complications such as atelectasis and pneumonia. Opioid medications can depress the respiratory system, making it crucial for the nurse to emphasize the importance of deep breathing to maintain optimal lung function. While managing pain and anxiety are important, facilitating deep breathing takes precedence in this situation to promote effective recovery and prevent respiratory complications.

Correct Answer: C

Rationale: Encouraging the use of an incentive spirometer is vital in preventing pulmonary complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, promoting lung expansion, and preventing atelectasis. Range-of-motion exercises help prevent musculoskeletal complications, while placing suction equipment at the bedside is important but not directly related to preventing pulmonary complications. Administering an expectorant may help with clearing secretions but is not as effective in preventing postoperative pulmonary complications as using an incentive spirometer.
