Final answer:
The response for the nurse aide to a visitor entering the room while changing a client is (D) "Would you please wait in the lobby?"
Step-by-step explanation:
In this situation, the nurse aide should prioritize the privacy and dignity of the client. By asking the visitor to wait in the lobby, the nurse aide ensures that the client's personal space is respected. Additionally, it is important to maintain professionalism and not make any inappropriate comments or invite the visitor to enter the room. Knocking before entering and asking for permission to enter would have been ideal, but given the situation, asking the visitor to wait in the lobby is the most appropriate response.
Using polite and respectful language is crucial in healthcare settings. The nurse aide should avoid using phrases like (A) "Can't you knock?" which can be perceived as rude and unprofessional. Similarly, (B) "Hi, come on in" may compromise the client's privacy, and (C) "Boy, he was dirty today" is an inappropriate comment that should not be made in front of a visitor. Therefore the correct answer is (D) "Would you please wait in the lobby?"
