Animal behavior

Mrs. Jones has a ten o'clock appointment for her new puppy to get a distemper booster, and has arrived on time by taxi. The receptionist has checked her in and she and the puppy are waiting in exam room one. You have taken the temp, pulse, and respiration and have weighed the puppy. You go to the refrigerator to get the distemper vaccine and realize that the last vaccine expired yesterday, the last day of the month. What should be done? (a) Vaccine should be used since it is only one day past its expiration date, (b) Vaccine should be used at twice its recommended dose for added efficacy. (c) If a feline distemper vaccine is available, it should be used instead. (d) Mrs. Jones should be given a new appointment on the date after the next shipment of vaccines comes in.
