NURS 4150 EXAM 2 QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100% CORRECT ANSWERS)
/ALREADY GRADED A+
Quiz: What are the functions of the placenta?
Ans: Excretion -Removing waste products from the fetus
Producing hormones that mature into fetal organs
Quiz: What is the role of amniotic fluid?
Ans: Will increase in volume as the pregnancy progresses Fetal stage, will
increase 10 mL/week 19 to 25 weeks' gestation, will increase 50 to 60
mL/week Approximately ONE liter at term
Quiz: What is the term for too-little amniotic fluid?
Ans: oligohydramnios
<500 mL at term
Quiz: What is the term for too-much amniotic fluid?
Ans: hydramnios
>2,000 mL at term
Quiz: What is autosomal dominant inheritance?
Ans: One copy of abnormal gene is needed for phenotype expression
,Example: Huntington Chorea; Dwarfism; Marfan Syndrome, Osteogenesis
Imperfecta
Quiz: What is autosomal recessive inheritance?
Ans: Both genes of pair must be abnormal for disorder to be expressed
Example: PKU; Sickle Cell Anemia; Cystic Fibrosis
Quiz: What is X-linked DOMINANT inheritance?
Ans: One copy of mutated gene on the X chromosome is needed for
phenotype expression,
Example: hypophosphatemia, Fragile X
Quiz: What is X-linked RECESSIVE inheritance?
Ans: Hemizygous males and homozygous females are affected
Example: color-blindness, hemophilia, and Duchenne Muscular Dystrophy
Quiz: What are the type 2 carrier screening for single-gene disorders?
Ans: Used to identify individuals who have a gene mutation for a genetic
condition but do not show symptoms of the condition because it is an
autosomal recessive inheritance
Examples: CF, Sickle cell disease, Tay-Sachs disease
Quiz: What is genetic testing?
Examstudy - Stuvia US
, Ans: the analysis of human DNA, RNA, chromosomes, and/or proteins to
detect abnormalities related to an inherited or medical condition
Quiz: What is preconceptual testing?
Ans: Done before conception:
Blood tests, preimplantation genetic diagnosis
Prenatal Testing- maternal/paternal
Blood test for various single gene disorders
Quiz: What is prenatal testing?
Ans: Testing on fetus before born
Quiz: What are type 1 tests?
Ans: *In clients with clinical symptoms or who have a family history of a
genetic disease*
Some of these genetic tests are prenatal tests or tests used to identify the
genetic status of a pregnancy at risk for a genetic condition.
Quiz: What are type 3 tests?
Ans: Predictive testing
Quiz: What is predisposition?
Ans: Does not indicate a 100% risk of developing the condition
