Which intervention should the nurse include in the plan of care for a client with leukocytosis?

A. Monitoring temperature regularly is correct because leukocytosis often indicates infection or inflammation, and fever is a key sign to detect early. B. Avoiding intramuscular injections is more relevant for clients with thrombocytopenia or bleeding disorders, not leukocytosis. C. Assessing skin for petechiae or bruising is important in thrombocytopenia but not typically associated with leukocytosis. D. Protective isolation is usually reserved for clients with neutropenia or immunosuppression, not those with leukocytosis, which indicates elevated white blood cells.
