A hypeensive pregnant woman at 34 weeks comes with history of pain in abdomen, bleeding per vaginum and loss of fetal movements. On examination the uterus is contracted with increased uterine tone. Fetal hea sounds are absent. Which of the following is the most likely diagnosis?

Okay, let's tackle this question. The patient is a 34-week pregnant woman with hypertension. She's presenting with abdominal pain, vaginal bleeding, loss of fetal movements, a contracted uterus with increased tone, and absent fetal heart sounds. The options probably include conditions like placental abruption, placenta previa, uterine rupture, or maybe something else.

First, the core concept here is probably placental abruption. Hypertension is a risk factor for abruption. The symptoms of pain, bleeding, uterine tenderness, and fetal demise are classic. Placental abruption often leads to abruptio placentae, which can cause these signs. The absence of fetal heart tones indicates fetal death, which is a severe outcome of abruption.

Now, the correct answer is likely placental abruption. Let's check why. Placental abruption occurs when the placenta separates from the uterine wall before delivery. It's associated with hypertension, trauma, or cocaine use. The bleeding is usually dark red and may be concealed. The uterus is tender and may be contracted. Fetal death is a possible complication due to placental insufficiency.

For the wrong options: Placenta previa would cause painless bleeding, but here there's abdominal pain. Uterine rupture is possible but less likely unless there's a history of C-section. Amniotic fluid embolism is sudden and more acute, leading to maternal shock. HELLP syndrome is a complication of preeclampsia but doesn't present with these symptoms.

The clinical pearl is that placental abruption is a hypertensive complication with pain and bleeding, leading to fetal demise if severe. Remembering that pain with bleeding suggests abruption, while painless suggests previa. Also, uterine tenderness and contractions are key signs.

So the correct answer is placental abruption. Let me structure the explanation accordingly.

**Core Concept**
This case tests knowledge of **placental abruption**, a hypertensive complication of pregnancy characterized by **premature separation of a normally implanted placenta**. Key features include **abdominal pain, vaginal bleeding, uterine tenderness/contraction, and fetal demise**, especially in severe cases.

**Why the Correct Answer is Right**
Placental abruption is strongly indicated by the clinical triad of **hypertension, abdominal pain, and vaginal bleeding**. The contracted uterus with increased tone (a "board-like" abdomen) and absent fetal heart sounds suggest **grade III abruption**, where placental separation is complete, leading to **fetal hypoxia and death**. Hypertension in pregnancy (preeclampsia) is a major risk factor, increasing vascular fragility and predisposing to placental separation.

**Why Each Wrong Option is Incorrect**
**Option A:** Placenta previa causes **painless, bright red vaginal bleeding**, typically in the third trimester, with no uterine tenderness or contractions.
**Option B:** Uterine rupture is rare and usually occurs in women with prior uterine scars; it presents with **sudden, severe abdominal pain, fetal bradycardia, and hemodynamic instability**, not absent fetal heart tones.
**Option C:** Amniotic fluid embolism is an acute, life-threatening condition causing **maternal respiratory/card

✓ Correct Answer: D. Abruptio placenta
