Chemical Reactions in Nursing Profession

M7: Chemical Reactions (please write paper with regards to the nursing profession):
Investigate how you will be using chemical reactions in your field. What will you need to understand how the reactions are occuring at the molecular level? What system is in place for you to understand this process? Describe at least one reaction and the system in which that reaction proceeds. If one of the reactants is limited what will happen to the reaction? Are there side reactions that might affect the outcome? How can we at the macro level control these reactions so they proceed as we foresee? What possible side effects or negative reactions can occur because of this reaction?
