Placenta is implanted in lower uterine segment, then it is called

Appeared in: UPPSC 2022

Explanation

Placenta previa is the medical term for a placenta that implants in the lower part of the uterus.
This implantation can partially or completely cover the opening of the cervix (internal os).
The classic sign of placenta previa is painless, bright red vaginal bleeding, usually after 20 weeks of gestation.
The location of the placenta in the lower segment is the defining characteristic of this condition.

Option B: Vasa previa involves fetal blood vessels, not the placental tissue itself, running across or near the internal cervical os. The primary risk is fetal hemorrhage if the vessels rupture.
Option C: Abruptio placenta is the premature separation of a normally implanted placenta from the uterine wall. It is about separation, not the initial location of implantation.
Option D: This option is incorrect because 'Placenta previa' is the correct medical term for the condition described in the question.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Complications of pregnancy related to placental implantation as background academic context rather than a clinical decision trigger.
Recognizing placenta previa is critical for preventing catastrophic maternal and fetal hemorrhage. The hallmark sign is painless, bright red bleeding.
A strict contraindication in suspected placenta previa is performing a digital vaginal examination, as it can provoke life-threatening bleeding. Diagnosis should be confirmed by ultrasound.
Management often involves expectant management (watchful waiting) if bleeding is not severe and the fetus is preterm, but delivery via cesarean section is almost always necessary.

How to Approach the Question

This is a factual recall question that tests your knowledge of obstetric terminology.
Read the stem carefully: 'Placenta is implanted in lower uterine segment'. This is a definition.
Analyze the options provided.
Recall the definitions of placenta previa, vasa previa, and abruptio placenta.
Match the definition in the stem to the correct term. Placenta previa is the direct definition of a placenta implanted in the lower uterine segment.
Eliminate the other options based on their definitions: vasa previa involves fetal vessels, and abruptio placenta involves premature separation.
