The large conducting artery depicted above is developing an aneurysm in region B. If flow through region C is 300 ml/min and the velocity of flow through region A is 100 mm/sec, then all of the following would be true EXCEPT:A) The velocity of flow through region C would be 100 mm/sec
B) The flow through region B would be 300 mg/min
C) Mean end pressure would be greater in region B than in region C
D) Wall tension would be greater in region C than in region B
E) Side pressure would be greater in region B than in region C
Uh-oh. There's math and formulae on this test? Ah, crap. In that moment, I realize that all my experience is in clinical disease, not the hardcore physics of fluid mechanics. This is just plain embarrassing. I feel like I should reimburse the money I made in my career if I can't pass CV physiology. I plow through the day getting increasingly more frustrated. Then today, I wake up and go right back at. I'm starting to get substantially more of the problems correct and feeling good about myself. I feel so good, that I decide to go out to a late lunch with my mom for brisket since it's been awhile. After lunch, I drop her off at home. I notice my dad is home so I decide to peak my head in to see how's he doing. He's upstairs and my mom goes up to see him. From down the stairs I hear a very concerned voice, "Zack, get up here."
I go up the stairs and my dad is in bed at 2 in the afternoon. Not the least bit normal for him. I take one look at the pallor of his skin and he's white as can be. I test his capillary refill and it's almost non-existent. Intense pain is present in his abdomen and when asked the location, he points to the upper left part, right below the ribs. Uh-oh. I palpate ever so gently as they've taught me, starting away from the pain and moving towards the area fearing what I'll find. When I get to the spot, he recoils in pain but before he does, I feel a very distinct swelling present. Uh-oh. The main organ that lives there is the spleen. Problem is that Mr. Spleen isn't supposed to be palpable unless it has enlarged to 3 to 4 times its normal size. Oh shit. I become increasingly concerned now. Splenomegaly is a very common and potentially very dangerous complication of leukemia and lymphoma. I call his oncologist and leave a message for the nurse. She calls back and tells me to get down to the emergency room. So here I am with my mom while my dad is getting a CT scan from the waist up to the top of his head. Once we get the results of the CT scan and the bloodwork, we'll go from there....
