Final answer:
Intonation is an element of verbal communication through voice tone and is not a nonverbal cue, implying the newly licensed nurse who mentioned it requires additional teaching on nonverbal communication.
Step-by-step explanation:
The question addresses an aspect of nonverbal communication within the field of nursing and requires choosing which response by a newly licensed nurse indicates a need for further teaching. Options A (Personal space), B (Posture), C (Eye contact), and D (Intonation) are given. Intonation, however, is related to the voice tone and is not a nonverbal cue. Nonverbal communication includes elements like personal space, body positioning, and eye contact. Intonation is considered a part of verbal communication since it involves the use of the voice to convey meaning. Therefore, the nurse who mentioned intonation requires additional teaching regarding nonverbal communication.
