-
Polyhydramnios is associated with which fetal anomaly?
सही उत्तर: घ) Oesophageal atresia
Inability of the fetus to swallow amniotic fluid (oesophageal or duodenal atresia, anencephaly) leads to polyhydramnios; renal anomalies cause oligohydramnios.

-
Severe oligohydramnios with pulmonary hypoplasia and flattened facies (Potter sequence) is classically associated with:
सही उत्तर: क) Bilateral renal agenesis
Amniotic fluid in later pregnancy is mainly fetal urine; absent kidneys cause severe oligohydramnios, limb deformities and lung hypoplasia.

Twin-to-twin transfusion syndrome occurs only in:
सही उत्तर: ग) Monochorionic twins

If a single fertilised ovum divides between days 4 and 8 after fertilisation, the resulting twins will be:
सही उत्तर: ख) Monochorionic diamniotic
Division before day 3 gives dichorionic diamniotic twins, days 4–8 monochorionic diamniotic, days 8–12 monoamniotic and after day 13 conjoined twins.

In face presentation, vaginal delivery is usually possible only when the position is:
सही उत्तर: घ) Mentoanterior
In mentoanterior position the head can be delivered by flexion under the symphysis; persistent mentoposterior face cannot deliver vaginally because the neck cannot extend further.

-
In a brow presentation, the presenting diameter is the:
सही उत्तर: क) Mentovertical, about 13.5 cm
The mentovertical diameter is the largest of the fetal head, so a persistent brow presentation with a normal-sized fetus cannot deliver vaginally.

-
The engaging diameter of the fetal head in a well-flexed vertex presentation is the:
सही उत्तर: ग) Suboccipitobregmatic (9.5 cm)
With full flexion, the suboccipitobregmatic diameter presents; deflexion brings larger diameters into play.

-
The shortest anteroposterior diameter of the pelvic inlet, through which the fetal head must pass, is the:
सही उत्तर: क) Obstetric conjugate
The obstetric conjugate (sacral promontory to the nearest point on the back of the symphysis, about 10.5–11 cm) is the shortest AP diameter of the inlet.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The most common type of female pelvis is:
सही उत्तर: ख) Gynaecoid
About half of women have a gynaecoid pelvis with a round inlet, which is the most favourable for vaginal delivery.
