Correct answer: B — Isolate with contact precautions, soap-and-water handwashing and sporicidal cleaning

The best answer is “Isolate with contact precautions, soap-and-water handwashing and sporicidal cleaning”. Suspected CDI warrants immediate contact precautions rather than waiting for laboratory confirmation. C. difficile spores resist alcohol, so soap-and-water hand hygiene and sporicidal environmental cleaning complement isolation and personal protective equipment while diagnosis and medicine review proceed.
