Patient actions and reactions at triage will be influenced by the nurse’s ability to manage the communication process. Communication is a two-way process that involves both verbal and non-verbal components equally. The better the communication, the more data gained and the more informed and accurate the triage assessment.

The energy to drive the chemical reactions of photosynthesis comes from the sunlight absorbed by the chlorophyll molecules. Hence, the first step in photosynthesis is the absorption of visible light from the sun by chlorophyll molecules. The chlorophyll molecules then transfer the light energy to chloroplasts, the reaction center of photosynthesis.
