Answer: What are the given nutritional instructions?
Since you haven't provided the options for this question which seems like a multiple choice question, I'll have to guess what you want.
As an example, a nurse could give a client asprin, or tell them to go to a location or use a mechanical item or digital item to calm themselves down. Massages, soothing videos, places to rest, all these may help to assist stress-prone clients.
Foodwise, processed meats, high sugar foods, caffeine and alcohol (which provide little nutritional value anyway) are all bad at reducing stress, and actually increase it. For some examples of comforting food to decrease stress, here's a small list:
Oatmeal, Asparagus, Salmon and tuna, Berries, Chamomile tea.
Tea is actually very good at soothing and releasing stress, many types of teas are natural stress releavers and are very very healthy, opposed to many alopathic solutions for edible stress releaf, such as pills.
