I would say D: appetite;
appetite is a strong desire or liking for something. At Holidays there is typically a large assortment of food that maybe you don't eat on a regular basis, therefore would have a big appetite for them.
Time and consistency of consumption, the effects of mixing this with other medication, the possible side affects of the medication.
I think the answer is A. it doesn't make sense
I would say B. Mostly because the patient won’t be able to speak and the patient has chills so obviously they may not be able to write and a translator will not help you figure out where the chest pain is or what they are mainly having a problem with. also, if you wait until your patient’s chest pains to sub side they will probably die to to their injuries depending on how bad it is, If I am wrong I apologize.
