There are two types of IUGR. They are ___________ and ___________.
Explanation
The correct answer is "symmetrical, asymmetrical". Intrauterine growth restriction (IUGR) refers to a condition where a fetus fails to grow at a normal rate inside the womb. Symmetrical IUGR is characterized by proportionate growth restriction, where all parts of the fetus are affected equally. Asymmetrical IUGR, on the other hand, is characterized by disproportionate growth restriction, where the head and brain are spared while the body and organs are disproportionately affected. Therefore, both symmetrical and asymmetrical IUGR are types of growth restriction that can occur during pregnancy.
3.
The "less" common of the two types of IUGR is __________.
Explanation
The less common type of IUGR is symmetrical. This means that the growth restriction affects both the head and the body proportionally. In symmetrical IUGR, the baby's weight, length, and head circumference are all smaller than expected for their gestational age. This type of IUGR is often caused by genetic factors, chromosomal abnormalities, or severe malnutrition during pregnancy.
4.
Symmetrical IUGR has a(n) _________ (early or late?) onset.
Explanation
Symmetrical IUGR is characterized by a proportionate reduction in the size of all organs and tissues, resulting in a smaller overall size for the fetus. This type of IUGR typically occurs early in pregnancy, during the first trimester or early second trimester. The early onset of symmetrical IUGR suggests that there may be underlying genetic or chromosomal abnormalities that affect the development of the fetus from the beginning of pregnancy.
5.
Symmetrical IUGR results in a reduction in ________, ________, and ________ growth.
Explanation
Symmetrical IUGR refers to a condition where the growth of the fetus is equally affected in all body parts. In this case, there is a reduction in the growth of the head, body, and limbs. The answer provided is a repetition of the correct sequence, stating that the reduction occurs in the head, body, and limbs, followed by the body, limbs, and head.
6.
The "more" common type of IUGR occurring in 70-75% of cases is the __________ type.
Explanation
In cases of intrauterine growth restriction (IUGR), there are two types: symmetrical and asymmetrical. The given answer states that the "more" common type of IUGR is the asymmetrical type, which occurs in 70-75% of cases. This suggests that asymmetrical IUGR is more prevalent compared to symmetrical IUGR.
7.
Choose the correct "maternal" etiology and risk factors for asymmetrical IUGR below.
Correct Answer(s)
A. Poor nutrition
A. Smoking
A. Drug abuse
A. Alcohol abuse
A. Heart condition
A. Diabetes
A. Younger than 17 or over 35
A. Chronic renal disease
A. Hypertension
Explanation
It's all of them
8.
Symmetrical IUGR is attributed to fetal problems such as:1) _________ infections,2) _________ abnormalities,3) Fetal exposure to _________,4) _________ defects
Correct Answer(s)
TORCH, chromosomal, toxins, genetic
Explanation
Symmetrical IUGR is characterized by proportional growth restriction in all parts of the fetus. This type of IUGR is often caused by various fetal problems. TORCH infections, which include toxoplasmosis, rubella, cytomegalovirus, and herpes simplex, can lead to symmetrical IUGR. Chromosomal abnormalities, such as Down syndrome, can also result in this condition. Fetal exposure to toxins, such as alcohol or drugs, can impair fetal growth and development. Additionally, genetic defects can contribute to symmetrical IUGR.
9.
The "placental" etiology and risk factors for asymmetrical IUGR include _________ insufficiency or __________ (placenta separates from the uterine wall).
Correct Answer(s)
placental, abruption
Explanation
Placental insufficiency refers to a condition where the placenta is unable to deliver enough oxygen and nutrients to the fetus, resulting in growth restriction. Placental abruption, on the other hand, occurs when the placenta detaches from the uterine wall before delivery, leading to bleeding and potential harm to the fetus. Both placental insufficiency and placental abruption are known risk factors for asymmetrical intrauterine growth restriction (IUGR), where the fetus experiences asymmetrical growth restriction, primarily affecting the abdominal region.
10.
Choose the correct sonographic findings for asymmetrical IUGR.
Correct Answer(s)
A. Abnormal doppler assessments of UA and MCA
A. Low BPP score
A. Oligo
A. Advanced grade of placenta
A. AC lags behind HC and FL
Explanation
It's all of them
