A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

Correct Answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.

Correct Answer: D

Rationale: After experiencing a pneumothorax, it is crucial for the client to be educated on potential complications. A productive cough can indicate infection or another issue, requiring prompt medical attention. Weakness, returning to work, and wearing a mask in crowded areas are important considerations but not as critical as monitoring for respiratory symptoms post-pneumothorax.

Correct Answer: A

Rationale: Bradycardia is not typically associated with a flail chest. Flail chest is characterized by paradoxical chest wall movement, respiratory distress, and hypoxia, but it does not usually cause bradycardia. The other options, such as cyanosis (bluish discoloration of the skin due to poor oxygenation), hypotension (low blood pressure), and dyspnea (difficulty breathing), are commonly seen in patients with flail chest due to the underlying respiratory compromise.

Correct Answer: D

Rationale: After a line is placed for hemodynamic monitoring, it is crucial to confirm its correct placement. The definitive way to verify the placement is through a chest x-ray. This ensures that the line is appropriately positioned without complications. Options A, B, and C do not address the essential step of confirming the line's placement, making them incorrect choices.

Correct Answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.

Correct Answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

Correct Answer: C

Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

Correct Answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.

Correct Answer: A

Rationale: In a client with a pulmonary embolism, bradypnea, which is abnormally slow breathing, is not an expected finding. Pulmonary embolism typically presents with tachypnea (rapid breathing) due to the body's compensatory mechanism to increase oxygen levels. Pleural friction rub, petechiae, and tachycardia are commonly associated with a pulmonary embolism due to the impaired oxygenation and increased workload on the heart. Therefore, the healthcare professional should not expect to find bradypnea during the assessment of a client with a pulmonary embolism.
