1. The _________ is the hollow organ within females in which the embryo and fetus develop.

• A. placenta
• B. ovum
• C. uterus
• D. amniotic sac

Correct answer: C

Rationale: The correct answer is C: uterus. The uterus is the organ where the embryo implants and the fetus develops during pregnancy. The placenta (choice A) is an organ that develops during pregnancy and provides nutrients and oxygen to the fetus, but it is not the organ where the embryo and fetus physically develop. The ovum (choice B) is the female reproductive cell or egg that is fertilized by the sperm to form an embryo, but it is not the organ where the embryo and fetus develop. The amniotic sac (choice D) is a membrane filled with amniotic fluid that surrounds and protects the fetus, but it is not the organ where the embryo and fetus physically develop.

2. When children who are reared by adoptive parents are nonetheless more similar to their natural parents in a trait, it can be concluded that:

• A. the genetic characteristics of the children change over time.
• B. heredity is solely responsible for how a child grows.
• C. the environment is solely responsible for the development of those characteristics.
• D. genetics play a role in the development of those characteristics.

Correct answer: D

Rationale: When children exhibit traits that are more similar to their biological parents than their adoptive parents, it indicates a strong genetic influence on those traits. This similarity suggests that genetics play a significant role in the development of the observed characteristics. Choice A is incorrect because genetic characteristics do not change over time in this context. Choice B is incorrect as it implies that heredity is the only factor, disregarding the impact of the environment. Choice C is also incorrect as it suggests that only the environment influences trait development, overlooking the genetic contribution.

3. Once the testes have developed in the embryo, they begin to produce male sex hormones, or _____.

• A. androgens
• B. genotypes
• C. blastocysts
• D. teratogens

Correct answer: A

Rationale: Androgens are male sex hormones, such as testosterone, produced by the testes after they have developed in the embryo. Androgens are responsible for the development of male secondary sexual characteristics. Genotypes refer to an individual's genetic makeup, not hormones. Blastocysts are early stage embryos, not male sex hormones. Teratogens are substances that can interfere with fetal development, not male sex hormones produced by the testes.

4. A nurse is caring for an infant who has signs of neonatal abstinence syndrome. Which of the following actions should the nurse take?

• A. Provide a calm environment
• B. Monitor blood glucose levels every hour
• C. Initiate seizure precautions
• D. Place the infant on their back with legs extended

Correct answer: C

Rationale: Initiating seizure precautions is crucial when caring for an infant with neonatal abstinence syndrome due to the increased risk of seizures. Providing a calm environment (Choice A) is important to reduce stimulation as these infants may be irritable. Monitoring blood glucose levels (Choice B) is not typically a priority in neonatal abstinence syndrome unless specific signs or symptoms suggest the need for this assessment. Placing the infant on their back with legs extended (Choice D) does not directly address the potential complications associated with neonatal abstinence syndrome, such as seizures.

5. A newborn assessment reveals spina bifida occulta. Which maternal factor should the nurse identify as having the greatest impact on the development of this newborn complication?

• A. Tobacco use.
• B. Folic acid deficiency.
• C. Short interval between pregnancies.
• D. Preeclampsia.

Correct answer: B

Rationale: Folic acid deficiency during pregnancy is strongly associated with neural tube defects like spina bifida occulta. Adequate folic acid intake before and during early pregnancy significantly reduces the risk of such complications. Tobacco use (Choice A) is linked to other adverse outcomes but not specifically spina bifida occulta. Short intervals between pregnancies (Choice C) can increase the risk of preterm birth and low birth weight but are not directly linked to spina bifida occulta. Preeclampsia (Choice D) is a hypertensive disorder that poses risks to both the mother and baby but is not the primary factor contributing to spina bifida occulta development.
