What is the most dangerous effect on the fetus of a mother who smokes cigarettes while pregnant?
Genetic changes and anomalies
Intrauterine growth restriction
Fetal addiction to the substance inhaled
Extensive central nervous system damage
The Correct Answer is D
Choice A reason: Genetic changes and anomalies are not the most dangerous effect, as they are rare and not directly caused by smoking. Smoking can increase the risk of some birth defects, such as cleft lip and cleft palate, but these are not genetic changes and can be corrected by surgery. Smoking can also cause chromosomal abnormalities in the eggs, but these usually result in miscarriage or stillbirth, not live births.
Choice B reason: Intrauterine growth restriction is not the most dangerous effect, as it is not life-threatening and can be managed by proper prenatal care and monitoring. Smoking can reduce the blood flow and oxygen delivery to the placenta and the fetus, which can impair the fetal growth and development. Smoking can also cause low birth weight, which can increase the risk of complications and infections in the newborn².
Choice C reason: Fetal addiction to the substance inhaled is not the most dangerous effect, as it is not permanent and can be treated by medication and supportive care. Smoking can expose the fetus to nicotine, carbon monoxide, and other harmful chemicals, which can cross the placenta and affect the fetal brain and nervous system. Smoking can also cause withdrawal symptoms in the newborn, such as irritability, tremors, and difficulty feeding.
Choice D reason: Extensive central nervous system damage is the most dangerous effect, as it is irreversible and can affect the child's health and development for life. Smoking can cause hypoxia (low oxygen) and ischemia (low blood flow) in the fetal brain, which can damage the neurons and impair the brain function. Smoking can also alter the brain structure and chemistry, which can affect the cognitive, behavioral, and emotional outcomes of the child. Smoking can increase the risk of learning disabilities, attention deficit hyperactivity disorder (ADHD), and mental disorders in the child.

Correct Answer is A
Explanation
Choice A reason: A previous birth of a large infant (macrosomia) is a risk factor for gestational diabetes mellitus (GDM). A large infant may indicate that the mother had high blood glucose levels during pregnancy, which can cause the fetus to grow larger than normal. Women who have had a large infant are more likely to develop GDM in subsequent pregnancies.
Choice B reason: Underweight before pregnancy is not a risk factor for GDM. In fact, being overweight or obese before pregnancy is a risk factor for GDM, as it increases insulin resistance and makes it harder for the body to use glucose effectively.
Choice C reason: A previous diagnosis of type 2 diabetes mellitus is not a risk factor for GDM. It is a contraindication for GDM, as it means that the woman already has diabetes before pregnancy. GDM is a condition that develops during pregnancy and usually resolves after delivery.
Choice D reason: Maternal age younger than 25 years is not a risk factor for GDM. In fact, being older than 25 years is a risk factor for GDM, as it increases the risk of insulin resistance and other metabolic changes that can affect glucose tolerance.
Correct Answer is B
Explanation
The correct answer is: B. 3-1-1-0-3.
Choice A reason:
This option suggests the woman has been pregnant four times, which is incorrect. She has had three pregnancies: one set of twins (counted as one pregnancy) and two singletons.
Choice B reason:
This is the correct option. The woman has had three pregnancies (Gravida = 3), one full-term delivery (Term = 1), one preterm delivery (the twins, Preterm = 1), no abortions (Abortions = 0), and three living children (Living = 3).
Choice C reason:
This option incorrectly suggests two preterm deliveries and one abortion, neither of which is indicated in the woman's history.
Choice D reason:
This option incorrectly suggests two preterm deliveries (the twins are counted as one preterm delivery) and does not accurately reflect the woman's history.
GTPAL stands for Gravida (total number of pregnancies), Term births (deliveries after 37 weeks), Preterm births (deliveries between 20-36 weeks), Abortions (losses before 20 weeks), and Living children. Normal ranges: Term (≥37 weeks), Preterm (20-36 weeks)
