Correct Answer: B

Rationale: Monitoring the effectiveness of tuberculosis medication is crucial to ensure the treatment is working properly. Regular sputum samples help in assessing the response to the medication. This monitoring can guide adjustments in the treatment plan if needed. Options A and C are incorrect as they do not reflect essential aspects of tuberculosis treatment. Option D is not a standard recommendation for tuberculosis treatment and may lead to misconceptions.

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: 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: C

Rationale: Albuterol is a bronchodilator commonly used to treat conditions like COPD. One of its common side effects is an increase in heart rate (tachycardia) due to its action on beta-2 receptors in the body. This statement by the client demonstrates an understanding of a potential side effect of albuterol, indicating comprehension of the discharge teaching provided by the healthcare provider.

Correct Answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.
