Nursing Elites

1. During the second month of pregnancy, __________.

• A. the umbilical cord first appears as a primitive body stalk
• B. touch sensitivity extends to most of the body
• C. the heart develops separate chambers
• D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.

2. The term teratogen refers to __________.

• A. any environmental agent that causes damage during the prenatal period
• B. a limited time span during which a part of the body is biologically prepared to develop rapidly
• C. a rapid period of prenatal neurological development
• D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.

3. The effects of stress on the developing organism can be greatly reduced if the expectant mother __________.

• A. has access to social support during stressful periods
• B. takes a low dose of anti-anxiety medication
• C. takes a folic acid supplement early in pregnancy
• D. is placed on bed rest during the last trimester

Correct answer: A

Rationale: Having access to social support during stressful periods can greatly reduce the effects of stress on the developing organism. Social support can provide emotional comfort, practical assistance, and a sense of belonging, which can help the expectant mother cope with stress more effectively. This support system can also help mitigate the negative impact of stress on the developing baby during pregnancy. Choices B, C, and D are incorrect because while folic acid is important for prenatal health, it does not directly address the effects of stress. Taking anti-anxiety medication should be done under medical supervision and as a last resort due to potential risks to the developing baby. Bed rest during the last trimester is not a solution to reduce the effects of stress and may not address the underlying causes of stress.

4. By age 2, children __________.

• A. take turns in face-to-face interaction
• B. can infer a speaker's indirectly expressed intention
• C. adjust their speech to fit the age of their listeners
• D. adjust their speech to fit the social status of their listeners

Correct answer: C

Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.

5. Theorists who contend that powerful negative events in the first few years cannot be fully overcome by later, more positive ones emphasize __________.

• A. plasticity
• B. stability
• C. nurture
• D. discontinuity

Correct answer: B

Rationale: Theorists who emphasize stability argue that powerful negative events early in life cannot be completely overcome by later, more positive experiences. They believe that early experiences have a lasting impact on development and are not easily erased or reversed by subsequent events. This perspective contrasts with the idea of plasticity, which suggests that development can be influenced by experiences at any point in life, and that individuals have the capacity for change and growth throughout the lifespan. 'Nurture' does not directly address the concept of overcoming negative events, while 'discontinuity' refers to developmental stages being separate and distinct, not the idea that negative events early in life persist despite later positive experiences.
