A nurse is caring for a client who is receiving methadone therapy as treatment for an opioid use disorder. Which of the following findings should indicate to the nurse that the client is experiencing the therapeutic effects of this medication?

A. Place the client in a negative pressure room: Negative pressure rooms are used for airborne precautions, such as tuberculosis, but are not required for internal brachytherapy. Clients receiving internal radiation require a private room with appropriate shielding to limit radiation exposure.

B. Dispose of the radioactive source in the client's trash can: Radioactive sources should never be discarded in regular trash. If dislodged, the source must be handled properly using protective equipment and disposed of in a designated lead container to prevent radiation exposure.

C. Limit each visitor to 1 hr per day: Visitors should be limited to 30 minutes per day and should maintain a distance of at least 6 feet from the client. This minimizes radiation exposure to family members and healthcare providers.

D. Use long-handled forceps if the radioactive source is dislodged: If the internal radiation source becomes dislodged, it should never be touched directly. Long-handled forceps should be used to carefully place the source in a lead-lined container to protect against radiation exposure.

A. Stop the infusion: Acute hemolytic reactions can occur within minutes of starting a transfusion and are life-threatening. Symptoms such as chills, lower back pain, and nausea indicate a potential reaction, requiring immediate discontinuation of the transfusion to prevent further hemolysis and organ damage.

B. Collect a urine sample: A urine sample helps detect hemoglobinuria, a sign of red blood cell destruction, but it is not the priority. The infusion must be stopped first to prevent further complications before obtaining a urine sample for analysis.

C. Check the client's vital signs: Monitoring vital signs is essential, but the priority is stopping the transfusion to halt the reaction. Vital signs should be checked after discontinuing the infusion to assess the severity of the reaction and guide further interventions.

D. Administer oxygen to the client: Oxygen may be needed if respiratory distress occurs, but stopping the transfusion is the first step to prevent continued exposure to the incompatible blood product. Oxygen therapy should be implemented based on the client's condition after discontinuing the infusion.
