A nurse is assisting with the care of several clients.The nurse should identify that which of the following client conditions requires contact precautions?

Choice A rationaleClostridium difficile requires contact precautions because it spreads through direct contact with contaminated surfaces or infected individuals. The organism produces spores that can survive on surfaces for long periods, making it highly contagious. Contact precautions help prevent the transmission by using protective equipment such as gloves and gowns and ensuring proper hand hygiene with soap and water.Choice B rationaleStreptococcal pharyngitis, also known as strep throat, primarily spreads through respiratory droplets rather than direct contact. Therefore, contact precautions are not typically required.Choice C rationaleHaemophilus influenzae spreads through respiratory droplets rather than direct contact. Droplet precautions are more appropriate to prevent its transmission, rather than contact precautions.Choice D rationaleMycoplasma pneumoniae also spreads through respiratory droplets and does not typically require contact precautions. Droplet precautions are more suitable for preventing its transmission.
