Correct Answer: D

Rationale: Encouraging the client to drink 2 to 3 liters of water daily helps to thin bronchial secretions, making them easier to expectorate. This can assist the client in coughing up the tenacious secretions. Maintaining a semi-Fowler's position can aid in improving lung expansion but may not directly address the issue of clearing the secretions. Administering oxygen via nasal cannula at 2 L/min can help improve oxygenation but does not specifically target the removal of bronchial secretions. Selecting a low-salt diet is important for overall health, but it does not directly address the client's immediate concern of clearing the bronchial secretions.

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: B

Rationale: In clients with laryngeal cancer, hoarseness is often one of the earliest manifestations due to vocal cord involvement. The irritation and inflammation caused by the tumor affect the vocal cords, leading to changes in voice quality. Dysphagia (choice A) typically occurs later as the tumor grows and interferes with swallowing. Dyspnea (choice C) and weight loss (choice D) may occur as the cancer progresses, but hoarseness is usually among the first signs to manifest in laryngeal cancer.

Correct Answer: B

Rationale: Continuous bubbling in the water-seal chamber indicates an air leak, which can compromise the system's integrity and affect the client's respiratory status. The other options are expected findings in a client with a chest tube drainage system: constant bubbling in the suction-control chamber indicates proper suction function, bloody drainage in the collection chamber is expected in the immediate postoperative period, and fluid-level fluctuations in the water-seal chamber demonstrate normal drainage and lung re-expansion.

Correct Answer: C

Rationale: When transporting a client with a chest tube connected to a closed drainage system, it is crucial to keep the drainage system below the level of the client's chest at all times. This positioning prevents the backflow of drainage into the client's chest, reducing the risk of complications. Clamping the chest tube, disconnecting it from the drainage system, or emptying the collection chamber are incorrect actions and can potentially harm the client or lead to complications.
