Question 15 - Single Best Answer
A sixteen year old female presents to the emergency room after a motor vehicle accident. Before losing consciousness, she complained of abdominal pain localized to the left upper quadrant. The EMS staff tells you that her blood pressure had been dropping during her ride to the hospital. Because of your astute histology background, you decide to do an ultrasound and CT scan because you remember that the spleen has an open circulatory system and she may be losing blood because of a splenic fracture. Your suspicions are confirmed by the radiologist. You call the general surgeon on call because your patient has lost consciousness and her blood pressure is 70/40 (i.e., bad). From an immunological stand point, should you worry about removing the spleen of a 16 year old?

Question 18 - Single Best Answer
A 56 year old female presents with anemia, back pain and hypercalcemia (increased amount of blood calcium). She is diagnosed with multiple myeloma, a cancer in which the plasma cell population takes over bony structures. Here is a photo of it. Notice the negative Golgi bodies in close proximity to the nuclei. Which of the following is a plasma cell?
Acute leukemia is a tumor in which the blood and bone marrow have an abundant number of immature cells, aka "blasts". Blood normally has mature cells and the bone marrow has immature cells, but not in such great number. Here are photos of leukemia (1 & 2). Notice the large, heterogenous nuclei. There is not supposed to be a question here, this is just for interest. Just what you need before the test, right?
