Correct Answer: B

Rationale: When administering prednisone, a corticosteroid medication, to a client with COPD, the healthcare professional should be aware of potential adverse effects. Tachycardia is not a common adverse effect of prednisone use. The correct adverse effects to monitor for include hypokalemia, fluid retention, and gastrointestinal issues like black, tarry stools due to potential gastrointestinal bleeding. Therefore, the healthcare professional should not concentrate on tachycardia but should focus on the other listed adverse effects when administering prednisone to a client with COPD.

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 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: B

Rationale: The correct answer is the statement 'I take antacids several times a day.' Antacids can alter the absorption of heparin, potentially affecting its effectiveness and increasing the risk of clot formation. This is a significant concern as it can impact the therapeutic outcome of heparin therapy. The other statements are not directly related to potential complications or interactions with heparin therapy.

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.
