Pregnancy and Childbirth

The exact cause of birthmarks is not fully understood by medical science. While some types of birthmarks may have genetic components or vascular origins, the mother's diet or emotional state during pregnancy is not scientifically proven to cause birthmarks. Option A is correct because it accurately reflects the current state of medical knowledge.

While dry skin does occur during pregnancy due to hormonal changes and fluid shifts, the most common skin condition is actually hyperpigmentation, particularly melasma (the 'mask of pregnancy'). Other very common pregnancy-related skin issues include stretch marks (striae gravidarum), acne due to hormonal fluctuations, and various pregnancy-specific dermatoses.

A baby shower is the traditional celebration held for expectant parents before the birth of a child. The other terms (Baby dos, Baby blessings, Baby boomers) are not the standard names for this celebration. Baby boomers refers to a demographic cohort.

High birth weight (macrosomia) is associated with increased risk of developing type 2 diabetes later in life due to metabolic programming and potential insulin resistance. Migraines, high blood pressure in early adulthood, and cardiovascular problems are less directly linked to birth weight in the same way.

Lotus birth is the practice of leaving the umbilical cord uncut after birth, allowing the placenta to remain attached until it naturally separates. The other flower names (rose, sunflower, daffodil) are not associated with this birth practice.

SIDS (Sudden Infant Death Syndrome), historically called "crib death," is the unexplained death of a seemingly healthy baby during sleep. Peak incidence is 2-4 months. "Altimers" is misspelled (Alzheimer's affects elderly); heart attacks in infants are extremely rare.

This is false; many hospitals and medical organizations do collect or 'sell' (transfer for a fee) umbilical cords and cord blood for medical research, stem cell treatments, and pharmaceutical use.

A human fetus develops unique fingerprints by approximately 4 months of gestation. This is when the ridges on the fingertips become distinct and permanent, influenced by genetic and environmental factors in the womb.

Fingerprints begin forming during the third month of pregnancy (weeks 9-12). They are fully formed by the sixth month, though they continue to grow in size as the fetus grows. The unique pattern is determined by genetic factors and the fetus's movement and position in the womb.

An obstetrician specializes in pregnancy, childbirth, and women's reproductive health. The prefix 'obstetr-' relates to birth and pregnancy care.

MTP is considered relatively safe during the first trimester, i.e. upto 12 weeks of pregnancy.

The baby's first stool is known as meconium.

At the end of the 8th week, the embryonic stage is over, and the fetal stage begins. By the end of the second month of pregnancy, the foetus develops limbs and digits.

The most common natural cause of abortion of an embryo is chromosomal abnormality, which accounts for at least 50% of sampled early pregnancy losses.

Placenta connects to the fetus by an umbilical cord,  which contains two umbilical arteries and one umbilical vein.
