Define and briefly discuss biotechnology
What will be an ideal response?
Biotechnology sees the human body as a collection of molecules and seeks to understand and treat disease in terms of these molecules. It attempts to identify the molecule causing a problem and then create another molecule to correct it. Specific drugs are aimed at inhibiting the work of a specific disease-causing agent. To be effective, the drug needs to bind to its target molecule. It needs to fit, something like a key in a lock. To achieve an exact fit, the precise structure of the target must be mapped. Powerful computers allow scientists to create graphical models.

During the attempted resuscitation of a 79-year-old man in cardiac arrest, a young man arrives at the scene and asks you to cease resuscitative efforts. He further tells you that the patient has entrusted him to make all of his medical decisions. You should:
A) continue full resuscitative efforts and ask the man if the patient has a living will and if he has documentation naming him as the person authorized to make decisions.

D) advise the man that, because he does not have valid documentation that he is authorized to make decisions for the patient, you must continue resuscitation.
