WOW... sweet score.
I don't want to start a new thread just for asking about #105
warning if you have not done the 150 free questions... STOP READING so not to spoil your test.
Is this right? I did not pick E cause ovaries drain into para-aortic lymph nodes. The answer I picked is D.
105. E is the correct answer.
In this patient with a history of ovarian cancer, the most likely cause of her edema is (E) obstruction of lymph vessels secondary to her malignancy. While various clinical conditions can cause edema, including congestive heart failure, cirrhosis, and nephrotic syndrome, these disorders are typically associated with pitting edema. This patient presents with nonpitting lymphedema, characterized by its involvement of an isolated limb. (A) Decreased capillary hydrostatic pressure would not cause edema, although increased capillary hydrostatic pressure would. (B) Decreased interstitial hydrostatic pressure is unlikely. (C) Increased capillary oncotic pressure would not cause edema, although decreased capillary oncotic pressure would. (D) Increased capillary permeability, as in seen in burns, trauma, inflammation, sepsis, and allergic reactions, may cause edema. However, this presentation makes lymphedema much more likely.
