10 Weeks pregnant lady, best method of aboion is
**Core Concept**
In 10 weeks of pregnancy, the focus is on medical termination of pregnancy (MTP) due to the gestational age. The best method of abortion at this stage should be safe, effective, and minimize complications.
**Why the Correct Answer is Right**
Medical termination of pregnancy (MTP) is recommended for 10 weeks of gestation. The most effective and safest method at this stage is a combination of Mifepristone and Misoprostol. Mifepristone acts as a progesterone receptor antagonist, blocking the action of progesterone necessary for pregnancy maintenance. This leads to decidualization and ultimately, fetal demise. Misoprostol, a prostaglandin E1 analog, induces uterine contractions and softening of the cervix, facilitating expulsion of the products of conception. This combination is more effective and safer than either medication alone.
**Why Each Wrong Option is Incorrect**
**Option A:** Surgical abortion (Dilation and Curettage or Dilation and Evacuation) is typically recommended for later gestations (beyond 12-14 weeks) due to increased risks associated with more advanced pregnancies.
**Option B:** Methotrexate is used for medical abortion in early pregnancy, primarily up to 7 weeks of gestation. Its effectiveness decreases beyond 7 weeks due to increased fetal size and the presence of more advanced gestational trophoblastic tissue.
**Option C:** Ethacrydine lactate is an abortifacient used in some countries but is not recommended due to its lower efficacy and higher risk of complications compared to Mifepristone and Misoprostol.
**Clinical Pearl / High-Yield Fact**
The World Health Organization (WHO) recommends Mifepristone and Misoprostol for medical abortion up to 10 weeks of gestation due to its high efficacy and safety profile.
**Correct Answer: D. Mifepristone and Misoprostol**
