32 years old pregnant lady presented with mild bleeding and pain. On examination uterus is tender and fetal hea sounds is absent. What is diagnosis?
First, the key symptoms here are bleeding and pain during pregnancy. Bleeding in pregnancy can have several causes. The most common ones are ectopic pregnancy, miscarriage, placenta previa, or placental abruption. Since the patient is pregnant, we need to consider her gestational age. If she's in the first trimester, ectopic or miscarriage are more likely. If it's later, placenta previa or abruption might be the case.
The uterus is tender, which could suggest an inflammatory process or a ruptured ectopic. Fetal heart sounds being absent is concerning. If the fetus is no longer viable, that points towards a miscarriage. However, if the bleeding is due to an ectopic pregnancy, there might not be fetal heart sounds because the pregnancy is outside the uterus. But ectopic pregnancies often present with more severe pain and bleeding, and maybe a history of amenorrhea.
Another possibility is a threatened miscarriage, but if the fetal heart sounds are absent, it's more likely an inevitable or complete miscarriage. Placenta previa would present with painless bleeding, which doesn't fit here. Placental abruption causes abdominal pain and uterine tenderness, but usually in later pregnancy. Since the question doesn't specify gestational age, but mentions fetal heart sounds being absent, it's more likely the pregnancy is no longer viable, pointing to miscarriage.
Wait, but if the uterus is tender, maybe it's an incomplete miscarriage where the products of conception are still in the uterus, causing inflammation. Ectopic pregnancy can also cause tenderness if there's internal bleeding. However, in ectopic, the uterus might be smaller than expected for dates, and the fetal heart sounds would be absent because the pregnancy is outside. But the presence of a tender uterus might be more consistent with a miscarriage.
So the most probable diagnosis here is an incomplete or complete miscarriage. The absence of fetal heart sounds and presence of bleeding and pain are classic for a miscarriage. The other options like ectopic or abruption need to be considered, but the key is the absence of fetal heart sounds indicating the pregnancy isn't viable. The correct answer would be miscarriage.
**Core Concept**
This question tests the differential diagnosis of bleeding and pain in pregnancy, focusing on conditions like miscarriage, ectopic pregnancy, and placental abruption. Absent fetal heart sounds indicate non-viability of the intrauterine pregnancy.
**Why the Correct Answer is Right**
The clinical scenario suggests **missed or inevitable miscarriage**. Bleeding, pain, uterine tenderness, and absent fetal heart sounds (even if previously documented) point to fetal demise or expulsion. Incomplete miscarriage causes ongoing bleeding and cramping, while complete miscarriage may present with resolution of symptoms. Uterine tenderness can occur due to retained products of conception or inflammation.
**Why Each Wrong Option is Incorrect**
**Option A:** *Ectopic pregnancy* typically presents with severe pain and absent uterine growth, but fetal heart sounds would never be heard.
**Option B:** *Pl
