A nurse leader is preparing an educational program on infection control measures. Which of the following conditions should the nurse include when discussing contact precautions?

Choice A reason: Streptococcal pharyngitis requires droplet precautions because it spreads via large respiratory droplets, not contact. Choice B reason: Scarlet fever also requires droplet precautions due to respiratory transmission. Choice C reason: Measles requires airborne precautions, not contact precautions, because of its ability to remain suspended in the air. Choice D reason: Varicella-zoster (shingles) requires contact precautions because the virus can spread through direct contact with lesions. In disseminated cases, airborne precautions may also be required, but contact precautions are essential for localized infections.
