Recognize the manifestations of fat emboli.

Explanation:

Typically a patient with trauma to the tibia or femur who has altered sensorium WITH pulmonary infiltrates and ARDS like picture. Very hypoxic.

You may be shown a picture of the fundus with a yellowish/whitish fat embolus seen in one of the retinal arteries.

It is unlikely that they describe shimmering fat globules in urine as the diagnosis will then be too easy.

CT head will be normal and no bacteria will grow out of any cultures.

Treatment is supportive. (To learn any more about this condition is useless for internal medicine)
