Correct Answer: A

Rationale: In this scenario, the client may have subcutaneous emphysema, where air leaks into the tissues surrounding the tracheostomy. The priority action for the nurse is to assess the client's oxygen saturation and other indicators of oxygenation to ensure adequate oxygen supply. If the client is stable, the nurse can then proceed to palpate the skin of the upper chest to check for subcutaneous emphysema. If the client is unstable, the nurse should promptly notify the Rapid Response Team. Using a bag-valve-mask device may be necessary for oxygenating the client, but assessing oxygen saturation comes first to guide further interventions.

Correct Answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.

Correct Answer: D

Rationale: While some of the other options may be helpful, the most appropriate advice for a client with COPD is to consume high-fiber foods to promote gastric emptying. Avoiding fluids just before and during meals can help prevent bloating, resting before meals can assist with dyspnea, and having several small meals a day can help reduce bloating. However, fibrous foods can lead to gas production, causing abdominal bloating and potentially worsening shortness of breath. Increasing calorie and protein intake is essential to prevent malnourishment. It is also important to avoid excessive carbohydrate intake, as it can increase carbon dioxide production and the risk of acidosis in COPD patients.

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: A

Rationale: In COPD, the client often develops a barrel chest, characterized by an increased anterior-posterior diameter of the chest. This change is due to air trapping and hyperinflation of the lungs. Decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typically associated with COPD. Weight loss is more common due to increased work of breathing and decreased energy expenditure in individuals with COPD.
