A certified nursing assistant (CNA) is caring for a client with Clostridium difficile diarrhea and asks the charge nurse, "How can I keep from catching this from the client" The nurse reminds the CNA to wash her hands and to ensure the client is placed
A．on protective isolation.
B．on neutropenic precautions.
C．in a negative-pressure room.
D．on contact isolation.
参考答案：D
解析：
C difficile can be transmitted from person to person by hands or waste containers such as a bedpan. When in direct contact with the client, the nurse should practice contact isolation, which includes wearing gloves and a gown. Protective isolation is used to protect a client who is immunocompromised, which isn't evident in this case. Neutropenic precautions are for clients with an absolute neutrophil count of 1,000/μL or less; this isn't evident in this case. A negative-pressure room is used when the organism is spread by the airborne route, which isn't true of C. difficile diarrhea.
