The nurse is caring for a 2 month old child with a fever of 101.76. The child also appears toxic with poor color. Which of the following actions would the nurse expect to implement as a priority?

A. While fluid replacement is important, in a toxic-appearing child, oral fluids may not be safe or adequate due to potential dehydration and risk of worsening condition. B. Administering antibiotics is the priority action because the child shows signs of potential serious infection, and timely antibiotic treatment is crucial in young infants who may quickly deteriorate. C. Obtaining a specimen for a complete blood count is necessary for diagnosing infection but is not as urgent as administering antibiotics. D. While obtaining a urinalysis may help identify a urinary tract infection, it is not the immediate priority compared to starting antibiotic therapy.
