Nursing Elites

1. If pregnancy does not occur, the corpus luteum shrinks, and the __________.

• A. cells begin to duplicate
• B. one-celled zygote multiplies and forms a blastocyst
• C. germinal period lasts only about two weeks
• D. lining of the uterus is discarded

Correct answer: D

Rationale: If pregnancy does not occur, the corpus luteum will shrink. As a result, the lining of the uterus is discarded through the process of menstruation. This shedding of the uterine lining is what causes menstrual bleeding. Choices A, B, and C are incorrect because they do not describe the physiological response of the body when pregnancy does not occur. The corpus luteum shrinking and the subsequent shedding of the uterine lining are part of the menstrual cycle, not processes related to cell duplication, zygote multiplication, or the duration of the germinal period.

2. The __________ reflex helps a newborn find the nipple.

• A. rooting
• B. Moro
• C. Babinski
• D. tonic neck Answer: A Page Ref: 101 Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate

Correct answer: A

Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.

3. Who is generally regarded as the founder of the child study movement?

• A. Arnold Gesell was among the first to write child-rearing books for parents
• B. Arnold Gesell is generally regarded as the founder of the child study movement
• C. Arnold Gesell foreshadowed lifespan research by writing a book on aging
• D. Arnold Gesell constructed the first successful intelligence test

Correct answer: B

Rationale: Arnold Gesell is generally regarded as the founder of the child study movement, emphasizing the importance of observing and documenting children's behaviors to understand their development. While he was a significant figure in child development research, he did not specifically write child-rearing books for parents, foreshadow lifespan research, or construct the first successful intelligence test. Choice A is incorrect as Gesell's focus was more on research rather than writing child-rearing books. Choice C is incorrect as Gesell's main contributions were in child development, not specifically in aging research. Choice D is incorrect as Gesell is not credited with constructing the first successful intelligence test.

4. In mammals, including humans, the sense of smell __________.

• A. does not become adultlike for several years
• B. helps mothers and babies identify each other
• C. is the least developed sense at birth
• D. takes about four months to become adultlike

Correct answer: B

Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.

5. In females, the twenty-third pair of chromosomes is labeled as __________.

• A. an autosome
• B. dizygotic
• C. XX
• D. XY

Correct answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
