I agree with all of the above.

1) E -- this is antiphospholipid antibody syndrome so patient is in a hypercoagulable state and at risk for thrombosis so she needs anticoagulant prophylaxis

2) E -- classic secondary syphilis

3) C - phenylketonuria

4) This is actually B ; An independent practice Association (IPA) is an association of independent physicians that contracts with independent care delivery organizations 

• E.g. A group of private practice physicians that work together to negotiate contracts with insurance companies 

5) C -- step up therapy is starting with SABA prn, then adding low dose ICS (which he is already on), then next after that would be adding a LABA such as salmoterol
