Which statement describes a key finding of the Human Genome Project?
- A. Humans produce one protein per gene.
- B. All human beings are 99.9% identical at the deoxyribonucleic acid (DNA) level.
- C. The Human Genome Project has not yet been able to translate the accumulating raw research into anything medically practical.
- D. Humans have more genes than other species.
Correct Answer: B
Rationale: The majority of the 0.1% genetic variations are found within and not among populations. Most human genes produce at least three proteins. The project's research has been very valuable in the identification of genes involved in disease and in the development of genetic testing. There are 20,500 genes in the human genome; scientists originally estimated more than 50,000 genes. Human genes are more efficient than the genes in other species, thereby increasing the human genetic complexity.

The microscopic examination of scrapings from the cervix, endocervix, or other mucous membranes to detect premalignant or malignant cells is called what?
- A. Bimanual palpation
- B. Rectovaginal palpation
- C. Papanicolaou (Pap) test
- D. Four As procedure

Which situation is most representative of an extended family?
- A. It includes adoptive children.
- B. It is headed by a single-parent.
- C. It contains children from previous marriages.
- D. It is composed of children, parents, and grandparents living in the same house.
Correct Answer: D
Rationale: An extended family is a type of family unit that includes not only the nuclear family (parents and children) but also other relatives such as grandparents, aunts, uncles, cousins, etc., all living together or in close proximity. Option D, which states that the family is composed of children, parents, and grandparents living in the same house, is most representative of an extended family structure. This situation reflects the multi-generational aspect of an extended family where multiple generations live together and contribute to the household dynamics.
A father and mother are carriers of phenylketonuria (PKU). Their 2-year-old daughter has the condition. The couple tells the nurse that they are having a second baby. Because their daughter has PKU, they are certain that this baby will not be affecteWhich response by the nurse is the most accurate?
- A. Good planning. You need to take advantage of the odds that are in your favor.
- B. I think you'd better first check with your physician.
- C. You are both carriers; therefore, each baby has a 25% chance of being affected.
- D. The ultrasound indicates a boy, and boys are not affected by PKU.
Correct Answer: C
Rationale: Each child conceived by this couple has a one-in-four chance of being affected with the PKU disorder. This couple still has an increased likelihood of having a child with PKU; having one child already with PKU does not guarantee that they will not have another. These parents need to discuss their options with their physician. However, an opportune time has presented itself for the couple to receive correct teaching about inherited genetic risks. No correlation exists between gender and inheritance of the disorder, because PKU is an autosomal recessive disorder.
Nurses who provide care to victims of IPV should be keenly aware of what?
- A. Relationship violence usually consists of a single episode that the couple can resolve.
- B. Violence often declines or ends with pregnancy.
- C. Financial coercion is considered part of IPV.
- D. Battered women are generally poorly educated and come from a deprived social background.
Correct Answer: C
Rationale: Economic coercion may accompany physical assault and psychologic attacks. IPV rarely ends with a single episode and often escalates during pregnancy.
A nurse is caring for a patient who states she is experiencing a thin vaginal discharge with a strong fishy odor. What test does the nurse prepare?
- A. whiff test
- B. vaginal culture
- C. urine culture
- D. blood test
Correct Answer: A
Rationale: A nurse caring for a patient who presents with a thin vaginal discharge with a strong fishy odor should prepare for performing a whiff test. The whiff test, also known as the amine or sniff test, is used to aid in the diagnosis of bacterial vaginosis (BV). BV is a common vaginal infection characterized by an overgrowth of harmful bacteria in the vagina and can cause symptoms like thin, grayish-white discharge with a strong fishy odor.
