The nurse is caring for a client with pneumonia who now develops initial signs of septic shock and multi-organ failure. The healthcare provider prescribes a sepsis protocol. Which intervention is most important for the nurse to include in the plan of care?

A. Ensuring comfort during the dying process is paramount in end-of-life care. Assessing and managing pain promptly supports quality of life and dignity in the client's final moments.
B. The nurse manager should be updated on the client's status. While communication with the nurse manager is important, it is not the immediate priority when a client is experiencing discomfort or pain.
C. The client's status should be conveyed to the chaplain. Involving spiritual care is important but secondary to addressing any immediate physical comfort needs of the client.
D. The impending signs of death should be documented. Documentation is important, but it is a secondary priority to the direct care and comfort needs of the client.

A. This intervention is likely to be ordered due to the patient's fever and elevated heart rate, which may suggest dehydration or the need for increased fluid intake to support hemodynamic stability and mitigate the effects of fever and potential dehydration from fever and nausea.
B. Given the diagnosis of Pneumocystis pneumonia, the patient will likely be on or start antibiotics specific to this infection, such as trimethoprim-sulfamethoxazole. Monitoring for adverse reactions is crucial, especially in a newly diagnosed HIV-positive patient who might be starting multiple new medications.
C. While it is important to monitor CD4 counts in HIV-positive patients to guide treatment decisions, repeating the CD4 count immediately might not be prioritized unless there are specific clinical changes that suggest a rapid decline in immune function. Given the recent test results showing a CD4 count of 443 cells/mm^3, immediate retesting might not be clinically justified unless guided by other symptoms or considerations not detailed here.
D. Pneumocystis pneumonia does not require airborne isolation as it is not typically contagious between people under normal circumstances. Instead, it arises as an opportunistic infection in individuals with weakened immune systems. Hence, this order would not be appropriate unless there were other infections suspected that require such precautions.
E. The patient reports severe nausea, which not only is distressing but can also prevent the patient from taking oral medications and maintain necessary nutrition. Administering an antiemetic can help manage this symptom effectively.
