Ricci Chapter 10 - Test Bank - 4th Edition || 100% Faultless
Solutions.
1. The nurse is teaching a couple about the pros and cons of genetic testing. Which statement by
the nurse best describes the limits of genetic testing?
A. "Various genetic tests help the primary care provider choose appropriate treatments."
B. "Genetic testing helps couples avoid having children with fatal diseases."
C. "Genetic tests identify people at high risk for preventable conditions."
D. "Some genetic tests can give a probability for developing a disorder." Correct Answer: D
Rationale: The fact that some tests only provide a probability for developing a disorder raises a
problem. A serious limitation of these susceptibility tests is that some people who carry a
disease-associated mutation never develop the disease. Choosing appropriate treatments,
avoiding having children with fatal diseases, and identifying those at high risk affirm the value of
genetic tests.
. The nurse is counseling a couple who suspect that they could bear a child with a genetic
abnormality. What would be most important for the nurse to do when working with this family?
A. Gather information for three generations.
B. Inform the family of the need for information.
C. Maintain the confidentiality of the information.
D. Present the information in a factual, nondirective manner. Correct Answer: D
Rationale: It is essential to respect client autonomy and present information in a factual,
nondirective manner. In these situations, the nurse needs to understand that the choice is the
couple's to make. Gathering information for three generations obtains a broad overview of what
has been seen in both sides of the family. Maintaining confidentiality of the information is as
important as with any other client information gathered. Informing the family of the need for
information is necessary because of its personal nature.
3. The nurse is teaching a couple about X-linked disorders because they are concerned that they
might pass on hemophilia to their children. Which response indicates the need for further
teaching?
A. "The father can't be a carrier if he doesn't have hemophilia."
B. "If the father doesn't have it, then his kids won't either."
C. "If the mother is a carrier, her daughter could be one too."
D. "If the mother is a carrier, her sons will have hemophilia." Correct Answer: B
Rationale: Males are more affected than females. A male has only one X chromosome, and all
the genes on his X chromosome will be expressed whereas a female will usually need both X
chromosomes to carry the disease. There is no male-to-male transmission (since no X
chromosome from the male is transmitted to male offspring), but any man who is affected will
have carrier daughters. If a woman is a carrier, there is a 50% chance that her sons will be
affected and a 50% chance that her daughters will be carriers.
4. A pregnant woman undergoes a triple screen at 16 to 18 weeks' gestation. What would the
nurse suspect if the woman's estriol and alpha-fetoprotein levels are decreased with high hCG
levels?
A. Down syndrome
, B. sickle-cell anemia
C. cardiac defects
D. respiratory disorders Correct Answer: A
Rationale: Decreased levels might indicate Down syndrome or trisomy 18. Sickle cell anemia
may be identified by chorionic villus sampling. Levels would be increased with cardiac defects,
such as tetralogy of Fallot. It does not detect respiratory disorders.
5. The nurse is conducting a presentation for a young adult community group about fetal
development and pregnancy. The nurse determines that the teaching was successful when the
group identifies that the sex of offspring is determined at which time?
A. during meiosis cell division
B. at fertilization
C. when the morula forms
D. during oogenesis Correct Answer: B
Rationale: Sex determination occurs at the time of fertilization. Meiosis refers to cell division
resulting in the formation of an ovum or sperm with half the number of chromosomes. The
morula develops after a series of four cleavages following the formation of the zygote.
Oogenesis refers to the development of a mature ovum, which has half the number of
chromosomes.
6. During a prenatal visit, a pregnant woman says, "I know the amniotic fluid is important, but
can you tell me more about it?" When describing amniotic fluid to a pregnant woman, which
description would the nurse most likely include?
A. "This fluid acts as transport mechanism for oxygen and nutrients."
B. "The fluid is mostly protein to provide nourishment to your baby."
C. "This fluid acts as a cushion to help to protect your baby from injury."
D. "The amount of fluid remains fairly constant throughout the pregnancy." Correct Answer: C
Rationale: Amniotic fluid protects the floating embryo and cushions the fetus from trauma. The
placenta acts as a transport mechanism for oxygen and nutrients. Amniotic fluid is primarily
water with some organic matter. Throughout pregnancy, amniotic fluid volume fluctuates.
7. Assessment of a pregnant woman reveals oligohydramnios. The nurse would be alert for the
development of which condition?
A. maternal diabetes
B. placental insufficiency
C. neural tube defects
D. fetal gastrointestinal malformations Correct Answer: B
Rationale: A deficiency of amniotic fluid, oligohydramnios, is associated with uteroplacental
insufficiency and fetal renal abnormalities. Excess amniotic fluid is associated with maternal
diabetes, neural tube defects, and malformations of the gastrointestinal tract and central nervous
system.
8. A couple comes to the clinic for preconception counseling and care. As part of the visit, the
nurse teaches the couple about fertilization and initial development, stating that the zygote
formed by the union of the ovum and sperm consists of how many chromosomes?
A. 22
