1. Which of the following is a situational barrier to seeking early prenatal care?
- A. psychological stress
- B. difficulty arranging transportation
- C. ambivalence about the pregnancy
- D. demands of taking care of other young children Answer: B Page Ref: 91 Skill Level: Understand newborn baby’s appearance. Topic: Childbirth Difficulty Level: Moderate
Correct answer: B
Rationale: Difficulty arranging transportation can be a situational barrier to seeking early prenatal care because it can prevent pregnant individuals from being able to physically get to their healthcare provider for appointments. This barrier may make it challenging for individuals to access the necessary prenatal care and support for a healthy pregnancy.
2. Where does the male produce sperm, and where are these glands located?
- A. penis; scrotum
- B. scrotum; penis
- C. testes; penis
- D. testes; scrotum
Correct answer: D
Rationale: The male produces sperm in the testes, which are two glands located in the scrotum. The scrotum is the external sac that houses and protects the testes, allowing for optimal temperature regulation to support sperm production. Choice A is incorrect because sperm production does not occur in the penis. Choice B is incorrect because the scrotum houses the testes, not the penis. Choice C is incorrect because sperm is produced in the testes, not the penis.
3. Which factor disrupts the brain's regulation of hunger and metabolism?
- A. Self-regulation
- B. Frequent eating out
- C. Reduced sleep
- D. Using screen media
Correct answer: C
Rationale: Reduced sleep is the correct answer as it affects hormones that regulate hunger and metabolism, leading to increased appetite and weight gain. Self-regulation is not directly related to the brain's regulation of hunger and metabolism. Frequent eating out may impact food choices and portion sizes but is not specifically linked to disrupting the brain's regulation. Using screen media can affect sleep patterns but is not as directly related to the brain's regulation of hunger and metabolism as reduced sleep.
4. The most rapid prenatal changes take place in the period of the __________.
- A. zygote
- B. blastocyst
- C. embryo
- D. fetus
Correct answer: C
Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.
5. Dr. O'Connor wants 90-year-old Mr. Takashi to participate in a research study that involves moderate risks. Mr. Takashi is incapable of consenting. Which statement best expresses your advice regarding Mr. Takashi's participation in the study?
- A. He should not be allowed to participate in the study under any circumstances.
- B. He should be allowed to participate in the study regardless of the benefit.
- C. He should be allowed to participate in the study only if his participation will benefit others.
- D. He should be allowed to participate in the study only if it is likely to benefit him directly.
Correct answer: D
Rationale: Mr. Takashi should be allowed to participate in the study only if it is likely to benefit him directly. This decision aligns with the principle of beneficence in research ethics, which emphasizes maximizing benefits and minimizing risks for research participants. Since Mr. Takashi is incapable of giving consent, his participation should be based on the likelihood of direct benefits to him rather than solely for the benefit of others or solely for research purposes. Option A is too restrictive and does not consider potential benefits to Mr. Takashi. Option B is flawed as it disregards the need for the study to benefit Mr. Takashi. Option C focuses on benefiting others, which is not the primary consideration when the participant cannot give consent.
