Penyakit darah Rh dapat terjadi apabila ibu dengan Rh negatif….
A. mengalami eritroblastosis.
B. gagal membentuk antibodi.
C. harus mengganti darahnya.
D. memiliki bayi Rh negatif.
E. memiliki bayi Rh positif

Jawabannya adalah E. memiliki bayi Rh positif.

Ketika seorang ibu yang memiliki Rh negatif menikah dengan lelaki yang memiliki Rh positif, maka anak dalam kandungannya mungkin memiliki Rh positif. Saat dalam kandungan, sel darah merah Rh positif anaknya dapat keluar menembus plasenta ke sistem sirkulasi ibunya. Hal tersebut menyebabkan si ibu memproduksi antibodi anti-Rh. Jika ibu tersebut hamil lagi dan anaknya memiliki Rh positif, antibodi anti-Rh ibu akan masuk lewat plasenta dan merusak sel darah merah anak. Akibatnya, anak kedua akan mengalami anemia berat dan dapat menyebabkan kematian. Keadaan seperti ini disebut penyakit eritroblastosis fetalis.

Jadi, jawaban yang benar adalah E. memiliki bayi Rh positif.
