Trivia Quiz On Abnormal Fetal Growth!

1. Which sex is more at risk for IUGR and Macrosomia?

Males are at increased risk for both

Females are at increased risk for both

Males are more at risk for Macrosomia and females more at risk for IUGR

Females are more at risk for Macrosomia and Males more at risk for IUGR

Males are more at risk for Macrosomia because they tend to have larger birth weights compared to females. On the other hand, females are more at risk for IUGR (Intrauterine Growth Restriction) because they are more likely to experience growth restriction in the womb, resulting in a smaller birth weight.

Explanation

Males are more at risk for Macrosomia because they tend to have larger birth weights compared to females. On the other hand, females are more at risk for IUGR (Intrauterine Growth Restriction) because they are more likely to experience growth restriction in the womb, resulting in a smaller birth weight.

2. A fetus which is IUGR may try to compensate for uteroplacental insufficiency through polycythemia. This is also called Hyperviscosity Syndrome. What symptoms are associated with this syndrome?

Multiorgan thrombosis

Heart failure

Hyperbilirubinemia

All of the above

Hyperviscosity Syndrome, also known as polycythemia, is a condition where there is an increased concentration of red blood cells in the blood. This can occur in a fetus that is experiencing intrauterine growth restriction (IUGR) due to uteroplacental insufficiency. The increased concentration of red blood cells can lead to several symptoms, including multiorgan thrombosis (blood clotting in multiple organs), heart failure (due to increased workload on the heart), and hyperbilirubinemia (elevated levels of bilirubin in the blood, which can cause jaundice). Therefore, all of the above symptoms are associated with this syndrome.

3. On average wow many weeks gestation should a female be to have the fundus level with the umbilicus?

18 weeks

20 weeks

24 weeks

30 weeks

The fundus level with the umbilicus is a measurement used to determine the gestational age of a pregnant female. Typically, the fundus reaches the level of the umbilicus at around 20 weeks of gestation. This means that the uterus has grown enough to reach the belly button. Therefore, the correct answer is 20 weeks.

4. What defines IUGR and What defines Macrosomia?

Fetus’s weight in the 10th percentile. A fetus weighing 4000-4500g or greater

Fetus’s weight in the 5th percentile. A fetus weighing 4000-4500g or greater

Fetus’s weight in 10th percentile. A fetus weighing 5000g or greater

Fetus’s weight in the 5th percentile . A fetus weighing 5000g or greater

IUGR, or intrauterine growth restriction, is defined as a fetus's weight in the 10th percentile. This means that the fetus weighs less than 90% of other fetuses of the same gestational age. On the other hand, macrosomia is defined as a fetus weighing 4000-4500g or greater, regardless of the percentile. Therefore, the correct answer is "Fetus's weight in the 10th percentile. A fetus weighing 4000-4500g or greater."

5. One of the most common problems in America today is tobacco smoking, and many women continue to smoke during pregnancy. A baby from a woman who smoked during pregnancy weighs, on average, how much less than a baby from a woman with a healthy pregnancy?

200g

400g

500g

100g

Tobacco smoking during pregnancy is a common problem in America. Research has shown that babies born to women who smoke during pregnancy tend to weigh less than babies from healthy pregnancies. The given answer of 200g suggests that, on average, a baby from a woman who smoked during pregnancy weighs 200g less than a baby from a woman with a healthy pregnancy. This highlights the negative impact of smoking on fetal development and emphasizes the importance of avoiding tobacco use during pregnancy.

6. The primary way to measure fetal weight is...

Leopold method

The fundal height

A & B

Neither A or B

The correct answer is A & B, which means that both the Leopold method and the fundal height are primary ways to measure fetal weight. The Leopold method involves palpating the abdomen to determine the position, presentation, and size of the fetus, which can indirectly estimate the fetal weight. On the other hand, the fundal height is measured by using a tape measure to determine the distance from the top of the uterus to the pubic bone, which can also provide an estimate of the fetal weight. Therefore, both methods are commonly used to measure fetal weight during pregnancy.

7. A 21 yo G2P0101 @ 32w3d with d=8 u/s has been diagnosed with IUGR. A doppler velocimetery has been conducted to determine how the fetus is coping with the IUGR. This exam measures what?

Fetal HR

Systolic/Diastolic velocity in the umbilical artery

Blood flow out of the fetal left atrium

Velocity of blood flow in the umbilical vein

A doppler velocimetry measures the systolic/diastolic velocity in the umbilical artery. This test is conducted to determine how the fetus is coping with IUGR (intrauterine growth restriction), which is a condition where the fetus is not growing at a normal rate. By measuring the blood flow in the umbilical artery, doctors can assess the adequacy of placental function and determine if the fetus is receiving enough oxygen and nutrients. Abnormal velocities in the umbilical artery may indicate compromised fetal well-being and the need for further intervention.
