OR >1 indicates increased occurrence of event. The only OR greater than 1 was in the table that indicated that the subject ate cookies but didn't drink milk. Thus, that is the only one with a significant occurrence

Alcoholic = pancreatic insufficiency. Linoleic, oleic, and palmitic acid can be absorbed without pancreatic lipases since they're just free fatty acids. Triglycerides need to be broken down by lipases before absorption.

Bile acids are the main method for eliminating cholesterol, not pancreatic enzymes

I thought of it like when she gets up from a prone position, she is decreasing the blood going to her heart, so so the the myxoma causes more obstruction. Also myxomas cause tiny emboli, which can go to the systemic circulation causing mini thrombi in the brain and limbs.

bigjimbo  Left atrial myxoma can mimic mitral stenosis (thus diastolic murmur)
btl_nyc  RVOT obstruction would cause a systolic murmur that gets louder when standing, not diastolic.

Since she has celiac spruce --> fat vitamin malabsorption, thus Vit. D is decreased Low vit. D = low calcitriol, low absorption of phosphate from intestine, and low absorption of Ca2+ causing an increase PTH

Acute asthma exacerbation 1. Albuterol 2. Corticosteroids 3. Ipratropium

youssefa  I guess they described a COPD exacerbation here since she's a smoker and Xray showed a wide AP diameter. Either ways Ipratropium would make the best answer since its used in both cases.

The thing is, the spinothalamic tract crosses 2 vertebral levels up and then decussates at the anterior white commissure to get from the right to the left, so how do I know which vertebral level I'd be working on this guy?

chris07  I think the assumption here is that we are dealing with the cord section at the level of the problem. The picture is incredibly misleading. You have to orient yourself. The dorsal columns F, E, A, B are facing the patient's posterior. Once you properly orient it in 3D space, you know that what's labeled "right" is actually the patient's left, and what's labeled "left" is his right side. Super confusing. +  
sne  The input arises in a limb/part of body at the level of lesion, enters through the dorsal root (pictured between A and B), decussates and ascends at the anterior commissure, and finally synapses on the second order neuron in the lateral spinothalamic tract. So the spinothalamic tract is responsible for contralateral pain and temperature sensation. So AT THE LEVEL technically would be in the dorsal column +2  
nwinkelmann  also, @chris07, I think you're wrong about the labels being wrong on the image. Becuase the spinothalamic tract = contralateral pain and temperature, and the patient's pain is on the right side, you would want to target the left spinothalamic tract for pain relief, i.e. the area labeled H. The area labeled D would be the right spinothalamic, purely because that is how the image is labeled. If you assume the label is different, you will get it wrong. +4
