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: C

Rationale: In pneumonia, lung tissue consolidation occurs, leading to dullness on percussion. This is a typical finding in pneumonia. Fremitus and decreased tactile fremitus are more commonly associated with conditions like pleural effusion or pneumothorax. Hyperresonance is typically seen in conditions causing air trapping, such as emphysema.

Correct Answer: B

Rationale: Immediate intervention is necessary when a client with a mediastinal chest tube exhibits tracheal deviation since it may indicate a tension pneumothorax. This condition requires prompt attention to prevent serious complications. While the production of pink sputum and pain at the insertion site should be monitored and reported, they do not typically require immediate intervention. Sudden onset of shortness of breath could indicate various issues related to the chest tube but is 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.

Correct Answer: C

Rationale: Suprasternal retraction during inhalation indicates the use of accessory muscles and difficulty in moving air due to airway narrowing, supported by bilateral wheezing and decreased pulse oxygen saturation. This client needs immediate intervention as their asthma is not responding to the medication. Administering oxygen to maintain saturations above 94% is crucial to ensure adequate oxygenation. While administering a rescue inhaler could also be necessary, oxygen therapy takes priority in this situation.
