Final answer:
The nurse should keep blood pressure equipment in the client's room and enforce strict infection control measures. Monitoring vital signs should be more frequent than every 8 hours, and fluid management must be individualized.
Step-by-step explanation:
A nurse planning care for a client undergoing a stem cell transplant should prioritize actions to prevent infection and ensure a safe environment for immunocompromised patients. The appropriate action from the provided options would be b. Keep blood pressure equipment in the client's room. This is vital as frequent monitoring is important to detect any complications early, and having dedicated equipment for the client minimizes the risk of infection. It's important to note that patients usually reside in protective isolation, such as in a positive airflow room to protect against infection rather than in a negative airflow room which is used for patients who have infections that can be spread through the air.
In addition to monitoring vital signs more frequently than once every 8 hours, the nurse should enforce strict infection control measures, such as hand hygiene and the use of personal protective equipment. The plan of care will often include strict fluid management, but the specific requirement to provide the client with 1000mL of water every 12 hours will depend on the individual's needs and should be determined on a case-by-case basis.
