Correct Answer is ["B","C","D"]
Explanation
Choice A rationale: Contact precautions are not necessary in this situation as the client is presenting symptoms of a possible infection related to chemotherapy-induced immunosuppression, not a contagious disease.
Choice B rationale: Placing the client in a private room is crucial to protect her from potential infections, given her compromised immune system due to chemotherapy.
Choice C rationale: Encouraging the client to increase fluid intake can help manage fever and muscle aches and keep her hydrated, which is important when dealing with symptoms of infection and fatigue.
Choice D rationale: Wearing a mask when caring for the client is necessary to protect both the client and the healthcare provider from potential infections, considering the client’s immunocompromised state.
Choice E rationale: Preparing to administer an antibiotic should be based on the healthcare provider's orders and further diagnostic results. While it might be necessary, it is not an immediate nursing action without provider confirmation.
