1. Hemoglobin binds to and has a much higher affinity for carbon monoxide (CO) than for oxygen. CO is colorless and odorless and can be produced in homes heated by natural gas; victims usually do not realize they are being poisoned and often die in their sleep. Describe the likely changes in a CO poisoning victim.

2. You are a physiologist on a space flight to a distant planet. You discover intelligent humanoid aliens inhabiting the planet, and they willingly submit to your tests. You discover that the alien's kidney handles the sugar alcohol mannitol just like our kidneys handle inulin. You also test the alien for its renal handling of glucose. The data from that experiment are: Plasma level (constant over 24 hrs): 6 g/dL of mannitol and 2 g/dL of glucose; 24 hr. urine sample: volume of 2 L, containing 144 g mannitol and 52 g glucose.

A. What is the alien's glomerular filtration rate?

B. What is the alien's clearance rate for glucose?

C. How does the alien kidney handle glucose?

A 27 year old female training to be a police officer comes into the clinic complaining of left, anterior, knee pain. She states that while running an obstacle course yesterday she was running on uneven ground and she twisted her knee, causing her to fall. She landed on her left knee and immediately experienced pain. The patient states that she is unable to bear weight and she is unable to move her knee into full extension or flexion. The patient has considerable swelling and she states that when it first happened there was a bump (or deformity) on the outside of her knee. Lastly, the patient states that when she does try to weigh the bear it feels like her knee is going to give out. The patient does not recall hearing a pop. Based on this information, come up with a differential diagnosis, identify possible structures involved, and come up with a treatment plan for this individual.

In 2012, a fraternity at the University of Tennessee was suspended
because a member of the fraternity, student A, was admitted to the
hospital with alcohol poisoning. Student A had a blood alcohol
level of 0.4, which is in the “death zone” for alcohol poisoning.
After questioning, it was revealed that two students were having a
drinking competition, Student A consumed vodka via an enema,
rectally, and Student B consumed vodka orally (P.O.). Student A and
B consumed the same amount of alcohol however, Student B did not
get alcohol poisoning. Provide a rational for why Student A
experienced alcohol poisoning and Student B did not. Be sure to
describe in detail the different routes of administration and the
expected alcohol plasma concentrations.
