The functions of amniotic fluid are?

a) Cushions the fetus

b) Allows fetal movement

c) Nutrient transport

d) Prevents adhesions

Appeared in: AIIMS Raipur NO - 2017 (Shift-1)

Explanation

Amniotic fluid provides a protective, buoyant environment for the fetus.
It acts as a shock absorber (cushion) against external pressures and impacts.
The fluid allows the fetus to move freely, which is crucial for the normal development of muscles and bones.
By keeping the fetus suspended, it prevents the developing limbs and body from adhering to the amniotic sac or to each other.

Option A: This option incorrectly includes 'Nutrient transport' (c) as a function of amniotic fluid.
Option B: This option incorrectly includes 'Nutrient transport' (c) as a function of amniotic fluid.
Option C: This option incorrectly includes 'Nutrient transport' (c) as a function of amniotic fluid.

Visual 1: Diagram - An illustration showing a fetus inside the uterus, surrounded by the amniotic sac and fluid. Labels should point to the fetus, amniotic fluid, placenta, and umbilical cord to differentiate their locations and imply their functions.
Visual 2: Table - A comparison table outlining the functions of the amniotic fluid versus the placenta, clearly distinguishing their roles in protection, nutrition, respiration, and excretion.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests the knowledge of the primary functions of amniotic fluid during pregnancy as background academic context rather than a clinical decision trigger.
Assessing amniotic fluid volume is a key part of antenatal care. The Amniotic Fluid Index (AFI) is a common measurement used in ultrasound.
Abnormal AFI can be a marker for fetal or maternal complications. Oligohydramnios (low fluid) may lead to cord compression or poor lung development, while polyhydramnios (high fluid) can increase the risk of preterm labor and is associated with conditions like maternal diabetes or fetal gastrointestinal blockages.
During labor, the color of the amniotic fluid is monitored. Meconium (first stool) staining can indicate fetal distress.

How to Approach the Question

First, read the question stem to identify the core concept: the functions of amniotic fluid.
Evaluate each of the four given statements (a, b, c, d) individually based on your knowledge of fetal development.
Determine which statements are correct and which are incorrect. Recall that the placenta is the primary organ for nutrient exchange.
Identify the incorrect statement: 'Nutrient transport' is not a primary function of amniotic fluid.
Eliminate all answer options that include the incorrect statement (c).
The only remaining option is 'a, b, d', which contains the three correct functions.
