Arterial blood gases on a postoperative client with pneumonia indicate the client is in respiratory acidosis. To best improve this acid-base imbalance, which intervention should the nurse implement?
Discontinue use of supplemental oxygen
Encouraging use of incentive spirometer
Implement fluid restrictions
Administering an antitussive agent
The Correct Answer is B
A. Discontinue use of supplemental oxygen: This option is incorrect because supplemental oxygen is used to increase the oxygen levels in the blood, which is not directly related to addressing respiratory acidosis. In respiratory acidosis, the problem is primarily with the elimination of CO2 rather than oxygenation.
B. Encouraging use of incentive spirometer: This is the correct choice as using an incentive spirometer helps improve lung expansion and promotes alveolar ventilation, which aids in reducing CO2 levels in the blood, thereby addressing respiratory acidosis.
C. Implement fluid restrictions: This option is not suitable because fluid restrictions do not directly address the underlying issue of respiratory acidosis. Fluid restrictions might be necessary for other conditions, but they are not effective in correcting respiratory acid-base imbalances.
D. Administering an antitussive agent: This is incorrect because antitussive agents suppress cough reflexes, which can be counterproductive. In respiratory acidosis, coughing is often a protective mechanism to help clear secretions, so suppressing it may worsen the acid-base imbalance.

Correct Answer is D
Explanation
A. Intraosseous line: Intraosseous lines are used for emergency situations when peripheral access is not available, and are not suitable for long-term chemotherapy administration due to the risk of complications and discomfort.
B. Intrathecal catheter: Intrathecal catheters are used for delivering medication directly into the spinal canal. They are not suitable for systemic chemotherapy administration, which requires vascular access.
C. Peripheral intravenous line: Peripheral intravenous lines are typically used for short-term treatments. They are not ideal for long-term chemotherapy because they need frequent replacement, and the veins can become damaged from prolonged use of chemotherapeutic agents.
D. Subcutaneous implantable port: A subcutaneous implantable port is the best option for long-term chemotherapy. It is implanted under the skin, reducing the risk of infection, and provides a stable and reliable access point for repeated treatments over several months.
Correct Answer is B
Explanation
A. Teach the client a relaxation technique to use until the next dose is due: While relaxation techniques can be helpful in managing pain, they are not sufficient for severe pain rated 9/10. The client requires more immediate pharmacological intervention.
B. Obtain an order for an immediate-release opioid for breakthrough pain: This is the most appropriate action. Immediate-release opioids are specifically used to manage breakthrough pain in clients on sustained-release opioid therapy. It addresses the client's severe pain effectively and promptly.
C. Explain to the client that the medication being administered lasts for 12 hours: Simply explaining the duration of the medication does not address the client's current severe pain. Effective pain management requires action, not just education.
D. Assess the client's vital signs and administer the next dose of opioids early: Administering the next dose early can lead to inappropriate dosing schedules and potential overdose. It is important to follow the prescribed dosing regimen and manage breakthrough pain appropriately.
