Correct Answer: A

Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.

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: C

Rationale: Cheyne-Stokes respirations are characterized by periods of deep, rapid breathing followed by periods of apnea. This pattern is often seen in clients with neurological or cardiac conditions. Kussmaul respirations are deep and rapid breaths often associated with metabolic acidosis. Apneustic respirations are characterized by prolonged inhalations with shortened exhalations and can indicate damage to the pons. Stridor is a high-pitched, noisy respiratory sound usually associated with upper airway obstruction.
Therefore, in this scenario, the client's alternating pattern of hyperventilation and apnea aligns with Cheyne-Stokes respirations.

Correct Answer: C

Rationale: An OSHA-approved N95 respirator mask is recommended when caring for a client with tuberculosis due to the airborne transmission of the disease. Tuberculosis poses a higher risk of transmission via respiratory droplets, making respiratory protection essential to prevent exposure and infection among healthcare workers.

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.
