MATERNAL-NEWBORNCHAPTER 4 TEST BANK/25
QUESTIONS AND ANSWERS
(A+)
A clinic nurse is planning a teaching session for
childbearing-age female patients. Which information
should the nurse include in the teaching session with
regard to avoiding exposing a fetus to teratogens?
A: eliminate use of acne medication
B: immunizations should be updated during the first
rimester of pregnancy
C: use of saunas and hot hubs during pregnancy should
be during the winter months only
D: alcoholic beverages can be consumed in the first and
third trimesters of pregnancy - √Answer :A: eliminate
use of acne medication
Elimination of non therapeutic drugs is the best action to
avoid teratogen exposure. Acne medication is not
essential during pregnancy. Immunizations for diseases
such as rubella are contraindicated during pregnancy.
Use of saunas and hot tubs are not recommended
because maternal hyperthermia is a significant
teratogen. Alcohol is an environmental substance
known to be teratogenic and should not be consumed
during pregnancy.
Quiz :The parents of a child with a karyotype of 47, XY,
+21 ask the nurse what this means. Which is the most
accurate response by the nurse?
,A: this karyotype is for a normal male
B: this karyotype is for a normal female
C: this karyotype is for a male with Down syndrome
D: this karyotype is for a female with Turner's syndrome
- √Answer :C: this karyotype is for a male with Down
syndrome
This child is male because his chromosomes are XY.
He has one extra copy of chromosome 21 (for a total of
47, instead of 46), resulting in Down syndrome. A
normal female would have 46 chromosomes and XX for
the sex chromosomes. A normal male would have 46
chromosomes. A female with Turner's syndrome would
have 45 chromosomes; the sex chromosome would
have just one X.
Quiz :People who have two copies of the same
abnormal autosomal dominant gene are generally:
A: mildly affected with the disorder
B: infertile and unable to transmit the gene
C: carriers of the trait but not affected with the disorder
D: more severely affected by the disorder than people
with one copy of the gene - √Answer :D: more severely
affected by the disorder than people with one copy of
the gene
People who have two copies of an abnormal gene are
usually more severely affected by the disorder because
they have no normal gene to compensate and maintain
normal function. Those mildly affected with the disorder
will have only one copy of the abnormal gene. Infertility
, may or may not be caused by chromosomal defects. A
carrier of a trait has one recessive gene.
Quiz :An infant is born with blood type AB. The father is
type A and the mother is type B. The father asks why
the baby has a blood type different from that of the
parents. The nurse's answer should be based on the
knowledge that:
A: both A and B blood types are dominant
B: types A and B are recessive when linked together
C: the baby has a mutation of the parents' blood types
D: type A is recessive and links more easily with type B
- √Answer :A: both A and B blood types are dominant
Types A and B are equally dominant, and the baby can
thus inherit one from each parent. Both types A and B
are dominant, not recessive. The infant has inherited
both blood types from the parents and this is not a
mutation. Both blood types A and B are equally
dominant.
Quiz :Which statement regarding multifactorial disorders
is correct?
A: they may not be evident until later in life
B: they are usually present and detectable at birth
C: the disorders are characterized by multiple defects
D: secondary defects are rarely associated with them -
√Answer :B: they are usually present and detectable at
birth
