Which isolation precautions should the nurse initiate for clients showing symptoms of hemorrhagic fever viruses?

The correct choice to initiate for clients showing symptoms of hemorrhagic fever viruses is contact isolation with double-gloving and shoe covers. Hemorrhagic fever viruses, such as those causing Ebola or Marburg, are highly contagious and can be transmitted through direct contact with bodily fluids of an infected person. This means that any healthcare worker interacting with these patients must take substantial precautions to prevent the virus from spreading.

Contact isolation is critical in this situation as it includes measures to prevent the transmission of infectious agents that are spread via direct or indirect contact. Double-gloving provides an additional barrier between the nurse and any potential infectious materials, significantly reducing the risk of virus transmission. Shoe covers further prevent the spread of contaminants from the environment.

Other options, while they might involve some level of precautions, do not effectively address the specific nature of hemorrhagic fever viruses. For instance, respiratory isolation is primarily focused on airborne pathogens, and using positive pressure rooms would not be appropriate in these cases since the goal is to contain the virus. Enteric precautions are pertinent for gastrointestinal pathogens, and reverse isolation is intended to protect immunocompromised patients from infections rather than isolating infectious patients themselves. Thus, contact isolation with specific protective gear is the comprehensive approach needed for managing cases
