Final answer:
It is true that a client would be placed on broad-spectrum antibiotics after a blood culture is drawn but before the culture results are available, as these antibiotics can target a wide range of bacteria when the specific pathogen is not yet identified.
Step-by-step explanation:
The nurse would expect a client to be placed on a broad-spectrum antibiotic after a blood culture is drawn but before the results are available. The answer to this is true. When a patient is suspected of having a bacterial infection, as evidenced by symptoms or clinical findings, initiating treatment with broad-spectrum antibiotics is a standard practice in medicine. This type of antibiotic is capable of acting against a wide range of bacteria, which is useful when the exact pathogen has not yet been identified. Once blood culture results are available and the specific pathogen and its antibiotic susceptibilities are known, the treatment can be adjusted to a more targeted antibiotic if necessary.
