During her second pregnancy 3 years later, she is screened each trimester for Rho(D) antibodies. An indirect antiglobulin test done during the third trimester indicates the presence of anti-Rho(D) antibodies in her serum. Which of the following is the most likely mechanism for the occurrence of these maternal antibodies?

hi kashdoc21 thanks for replying.
i think answer for 1) is r.renal vein(The physician may also measure and compare the level of renin, (blood pressure-regulating hormone released by the kidneys), within the right to the left renal veins. If the amount of renin that is released by one-side is markedly higher than the other, this identifies a high renin-releasing kidney consistent with RAS. ) is this right.
2)D 21-OH deficiency
3)F squamous cell ca-can you explain why you said burkitts
4)I had a doubt between B-TB and E-Klebsiella(some have said this is the answer as it affects alcoholics,causes upperlobe cavity with bloody,mucopurulent sputum.can u explain
5)I think A) as malabsortion causes decreased ca& phosphorus absorption,increasing PTH and Alk Phosphate
6)D) Narrowing of the capillary wall by fibrin deposition
7) C-↓K ↓Renin ↑K excretion -fludrocortisone is mineralocorticoid.increasesNa,decreases K,increases excretion and decreases renin
8)think A-collagenase not sure
9)A
10)c as gingivitis caused by Gr Neg bacilli
11)sorry coudnt post the picture but there was no clear kidney?adrenal in that CT.
12)C ant wall of L.Ventricle by LAD,Lat free wall L Circumflex,Inf wall RCA(hope I am right)
Q)An infant was born by uncomplicatede delivery,APGAR 9-10 with a swelling on the posterior border of Sternocleidomastoid what is it
a)Branchial cystB)cystic hygromaC)thyroglossal cyst d)Dermoid cyst
I feel the answer is B.can u discuss
