D. lung cancer as it is a long term problem
A is unrealistic b sounds right and c isn't right because that is encouraging people to just give up
Computer RAM has essentially the same characteristics. Your computer often does not have enough memory to run certain programs, and when you turn it off, bye-bye data! Your long-term memory is something like a computer's hard drive. Both of them take longer to respond, but can store a considerable quantity of data.
I think that was right of the Nurse to do so because the person in the accident was exposed to someone whose blood was HIV positive, and so now they might have it too.
I would have consulted with the patient about if it was okay to let the other person know that they could now be infected with HIV and if the HIV positive patient said it was fine I would go back and tell the other patient.
hope that helps :)
