According to UW, alcohol abuse is a risk factor for avascular necrosis. The most common site is the femoral head, which presents with pain that is exarcebated by weight bearing without inflammatory signs on physical examination.

What about pulmonary vascular resistance? It follows the systemic vascular resistance?

cooldudeboy1  crackles are heard bilaterally so there is pulm patho which leads to increased pulm vascular resistance, since systemic blood flows into the lungs. any block in the flow ahead (lungs) will increase resistance in flow behind ( systemic )

Per First Aid 2018 (pg 421) & Merck Manual

a) CML is not the answer because in CML you have HIGH WBCs & Platelets. In the stem there is only high platelets. b) Is the answer because in Essential Thrombocythemia we have normal WBCs and RBCs, just high platelets. c) Myeloid metaplasia refers to well a metaplasia in myeloid cells which are basophils, eosinophils, etc. d) In Polycythemia Vera we have HIGH RBCs, WBCs, and Platelets. e) Reactive thrombocytosis- is a elevated platelet count that occurs secondary to another disorder like:

-Chronic inflammatory disorders (eg, rheumatoid arthritis, inflammatory bowel disease, tuberculosis, sarcoidosis, granulomatosis with polyangiitis) -Acute infection

-Hemorrhage

-Iron deficiency

-Hemolysis

-Cancer

-Splenectomy or hyposplenism
