Help PLEASE!!!!

So I had this patient this past week... In for wheezing, 3 months old, no infection, and No other Dx was made. But abnormal labs are as follows:
Hgb: 8.6 (L) Hct: 26.0 (L) MCV: 72.1 (L) MCH: 23.9 (L)
RDW: 17.6 (L) Plt: 469 (H)

So obviously there is some microcytic anemia going on... My question is, Is there any way these labs could be related to the respiratory issues? and how? I have some thoughts on it, but not sure if my rashionals are valid. ALso, you should know the newborn only consumes Gentlease (which is iron fortified), so the anamia shouldn't be diet related.

Also, My pt had RSV a month ago. Now the creatinine is low and potassium is high... RSV related?

FYI, This is not part of my homework, Im just trying to peice it all together in my head.

THANKS!!!!!!
