Question 1

Which of the following is used to obtain placental tissue samples?
A) Amniocentesis
B) Karyotype
C) Chorionic villus sampling
D) Pedigree

Accepted Answer

Chorionic villus sampling (CVS) is a prenatal test in which a sample of placental tissue is removed and analyzed to detect chromosomal abnormalities and genetic disorders. This is done by inserting a needle or tube through the mother's cervix or abdomen to obtain a small sample of the chorionic villi, which are finger-like projections on the placenta that contain fetal cells. Amniocentesis is a different type of prenatal test that involves removing a sample of amniotic fluid, while karyotyping is a laboratory technique used to analyze chromosomes. Pedigree is a graphical representation of inherited traits in a family but is not a method of obtaining placental tissue samples.

Question 2

Down syndrome is also known as:
A) trisomy 12.
B) trisomy 13.
C) trisomy 18.
D) trisomy 21.

Accepted Answer

Down syndrome is caused by the presence of an extra copy of chromosome 21, which is known as trisomy 21.

Question 3

Sophia Smith was born vaginally today at the hospital with Apgar scores of 9 and 10. On her day 2 visit, the doctor diagnosed Sophia with congenital lordosis of her lumbar spine. What codes are assigned?
A) Z38.00, Q76.425
B) Z38.00, Q76.426
C) Z38.01, Q76.425
D) Z38.01, Q76.426

Accepted Answer

B is the correct choice because Z38.00 indicates the live birth occurred within the hospital setting, and Q76.426 represents congenital lumbar spine lordosis. A is incorrect because it uses the wrong subtype of lordosis. C and D are incorrect because they falsely indicate that the birth occurred outside of a hospital setting.

Question 4

Which of the following fetal conditions is not eligible for prenatal repair?
A) Closure of neural tube defects
B) Cystic fibrosis
C) Congenital diaphragmatic hernias
D) Spina bifida

Accepted Answer

Cystic fibrosis is a genetic disorder that affects the lungs, pancreas, and other organs, and cannot be treated with prenatal surgery. The other conditions listed (closure of neural tube defects, congenital diaphragmatic hernias, and spina bifida) can potentially be treated with fetal surgery.

Question 5

What is the correct code for a patient with an atrial septal defect?
A) Q21.0
B) Q21.1
C) Q22.0
D) Q22.1

Accepted Answer

Atrial septal defect is coded as Q21.1 according to the ICD-10 classification of diseases.

Question 6

Jerika Jones is seen today for Down syndrome. What code is assigned?
A) Q90.0
B) Q90.1
C) Q90.2
D) Q90.9

Accepted Answer

Q90.9 is the correct ICD-10 code for Down syndrome, unspecified. The other codes specify different types or manifestations of Down syndrome, but without additional information, the unspecified code is most appropriate.

Question 7

The CDC estimates that there are how many babies are born in the United States each year with congenital heart defects?
A) 100,000
B) 200,000
C) 300,000
D) 400,000

Accepted Answer

The answer of The CDC estimates that there are how...

Question 8

What is the correct code for a patient diagnosed with Goldberg-Maxwell syndrome?
A) Q89.9
B) Q89.90
C) E34.5
D) E34.51

Accepted Answer

Goldberg-Maxwell syndrome is coded under E34.51, which is the specific ICD-10 code for this rare genetic disorder.

Question 9

Which of the following is used to collect amniotic fluid?
A) Amniocentesis
B) Karyotype
C) Chorionic villus sampling
D) Pedigree

Accepted Answer

Amniocentesis is a prenatal diagnostic test that involves taking a sample of amniotic fluid, which is the fluid that surrounds a developing fetus in the uterus. The sample is collected using a thin needle inserted into the amniotic sac through the mother's abdomen. This test is commonly used to detect genetic disorders and chromosomal abnormalities in the fetus.

Question 10

What is the correct code for a patient with Erdheim syndrome?
A) E22.0
B) E22.1
C) E88.89
D) E88.90

Accepted Answer

Erdheim syndrome is a rare condition characterized by the accumulation of histiocytes in various organs and tissues. The correct code for this condition is E22.0, which is the code for "Histiocytosis, Langerhans cell, multisystem."
