A nurse working on a medical-surgical unit suspects that several clients have Clostridium Difficile (C-Diff) when they all develop watery diarrhea. Which of the following actions should the nurse plan to take while waiting for the client's lab results?

A. Place all clients who have manifestations on contact precautions: Implementing contact precautions immediately is crucial to prevent the spread of C. difficile infection, which is highly contagious via spores. This includes using gloves and gowns and isolating affected clients until lab confirmation is received. B. Request the providers to initiate antibiotic therapy for every client on the unit: Starting antibiotics indiscriminately can promote resistance and disrupt normal flora. Treatment should be based on individual diagnosis and provider orders after lab confirmation. C. Perform hand hygiene with an alcohol-based agent: Alcohol-based hand sanitizers are not effective against C. difficile spores. Handwashing with soap and water is necessary to physically remove spores after caring for infected clients. D. Obtain stool cultures from all clients on the nursing unit: Stool cultures should be obtained only from clients who present symptoms consistent with infection, not indiscriminately from all clients, to avoid unnecessary testing and delays in appropriate care.
