Which type of communication is followed by video conferencing?

Appeared in: RRB Nsg. Superintendent 21 July 2019 (shift 1st)

Explanation

Video conferencing allows users in different locations to hold face-to-face meetings using technology (SRC_3).
It is classified as 'Audio-visual' because it transmits both sound (audio) and images (video), engaging both hearing and sight.
It is 'Two-way' because communication is interactive and flows in both directions, from sender to receiver and back, allowing for real-time feedback and dialogue (SRC_1, SRC_2).
This simultaneous, interactive exchange distinguishes it from one-way forms of communication.

Option A: This is incorrect because video conferencing includes an audio component, allowing participants to speak and hear. 'Visual one way' implies only images are transmitted without sound and without interaction.
Option B: This is incorrect because video conferencing is interactive. 'One way' communication does not allow for immediate feedback from the receiver, which is a core function of a conference.
Option C: This is incorrect because video conferencing fundamentally relies on audio for spoken communication. 'Visual two way' would mean the interaction happens only through visual means.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types of Communication as background academic context rather than a clinical decision trigger.
This concept is highly relevant in modern healthcare due to the rise of telemedicine and telehealth.
Nurses frequently use audio-visual two-way communication for virtual consultations, patient education, remote monitoring, and collaborating with other healthcare professionals in different locations.
Understanding the interactive nature of this technology is crucial for effective and empathetic patient care, as it allows the nurse to assess both verbal and non-verbal cues.

How to Approach the Question

First, break down the term 'video conferencing'. 'Video' implies a visual component, and 'conferencing' implies a meeting or discussion, which is interactive.
Analyze the components: 'Video' means it must be 'visual'. The presence of speech means it is also 'audio'. Therefore, it is 'audio-visual'.
Next, analyze the interaction type. A 'conference' is a discussion where people talk back and forth. This means the communication is 'two-way', not 'one-way'.
Combine the components: The communication is both 'audio-visual' and 'two-way'.
Scan the options to find the one that matches this combination: 'Audio-visual two way'.
