Good morning. As part of your orientation to campus life, the dean’s office has scheduled a short tour of the medical clinic and the infirmary. We, on the nursing staff, hope that none of you get sick.
    But just in case you do become ill, we want you to know what procedures to follow. If you have a really bad cold, it’s a good idea to have one of us check you over at the clinic. Several students last year didn’t see a nurse about their bad colds and they developed terrible coughs. It’s possible to get pneumonia when you neglect the cough. If you do get something as serious as pneumonia, you’ll have to come and stay in the infirmary. A doctor visits the infirmary regularly.
    On the other hand, if you just have an ordinary cold, you can usually stay in your dormitory room. Many students try to keep up with their usual activities when they don’t feel well. As a result, they often get much sicker. I think it’s wise to rest more and skip a few classes. If you are ill, you can always get a medical excuse from one of us or from the doctor. The clinic hours are from nine to twelve every weekday morning. But there is an emergency number you can call anytime. The emergency number is on the front of your campus telephone book. You’ll find a phone book in each dormitory room. Before we start on our tour of the infirmary, do you have any questions?
