What steps should be taken before administering a broad spectrum antibiotic?

A. While monitoring vital signs is important, it is not the first step in the antibiotic administration process. B. Performing a culture and sensitivity test to identify the specific pathogen and its susceptibility is essential before administering a broad-spectrum antibiotic, as this ensures that the chosen antibiotic will be effective against the identified infection. C. Administering the antibiotic immediately without obtaining a specimen sample may lead to ineffective treatment and can hinder identifying the causative agent later. D. While consulting with the healthcare provider for appropriate dosage is important, it should follow the identification of the specific organism.
