11. Yоu аre а nurse аnd yоu suspect that yоu may have been exposed to a particular virus. You and your health care provider decide to perform a hemagglutinin assay. A sample of your serum is taken and added to a sample of virus. Next, the virus and serum sample are added to erythrocytes. Upon examination, you do not see any agglutination occurring.

See example below: "A teacher works a 40-hour week in which 4 hours a day are dedicated class time. She holds office hours on Monday, Wednesday and Thursday from 2:30-3:30 pm and attends department meetings every Friday (which last 1 hour). How many hours does she have left in her week for other tasks, such as course preparation, grading, curriculum design and other faculty obligations?"
