Correct Answer: B

Rationale: Immediate intervention is required if the client exhibits tracheal deviation as it could indicate a tension pneumothorax, a life-threatening condition that requires prompt attention to prevent respiratory compromise. Production of pink sputum may indicate bleeding but would not be as immediately life-threatening as tracheal deviation. Drainage greater than 70 mL/hr could indicate hemorrhage, which also requires attention but is not as urgent as tracheal deviation. Sudden onset of shortness of breath could indicate various issues, including dislodgment of the tube or pneumothorax, which require intervention but are not as critical as tracheal deviation in this context.

Correct Answer: D

Rationale: A silent chest in a client experiencing an acute asthma attack indicates severe airway obstruction and impending respiratory failure. It is a critical finding that requires immediate intervention as it signifies a lack of airflow and ventilation. Loud wheezing, increased respiratory rate, and use of accessory muscles are common signs of an asthma attack and indicate the body's attempt to compensate. However, a silent chest suggests a dangerous lack of airflow that necessitates urgent medical attention to prevent respiratory arrest.

Correct Answer: D

Rationale: The correct answer is D because prednisone, a corticosteroid, should not be abruptly stopped. It must be tapered off gradually to prevent adrenal insufficiency. Choices A, B, and C demonstrate proper understanding of the medication's use and side effects, emphasizing the importance of daily intake, infection prevention, and taking it with food to avoid stomach upset.

Correct Answer: B

Rationale: When food particles are noted during suctioning of a client with a tracheostomy tube, it can indicate tracheomalacia due to constant pressure from the tracheostomy cuff. This condition may lead to dilation of the tracheal passage. To address this issue, the nurse should measure and compare cuff pressures. By monitoring these pressures and comparing them to previous readings, the nurse can identify trends and potential complications. Elevating the head of the bed, placing the client on NPO status, and requesting a swallow study will not directly address the cuff pressure issue causing food particles in the secretions.

Correct Answer: D

Rationale: A decrease in the client's respiratory rate to 10 breaths per minute, while receiving oxygen therapy for COPD, is a concerning finding that may indicate carbon dioxide retention and respiratory depression. This situation requires immediate action to prevent further complications. An oxygen saturation of 90% is within an acceptable range for COPD patients on oxygen therapy. A respiratory rate of 22 breaths per minute and reports of shortness of breath are common in clients with COPD and may not necessitate immediate action unless accompanied by other concerning symptoms.
