1. How does physical activity impact mental health?

• A. Reduces anxiety and depression
• B. Improves mood, but decreases alertness
• C. Decreases mood, alertness, and energy
• D. Decreases neural activity in the cerebral cortex

Correct answer: A

Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.

2. During the period of the embryo, the __________ becomes the __________.

• A. mesoderm; nervous system, lungs, internal organs, and skin
• B. chorion; endocrine system, muscles, placenta, and skeleton
• C. ectoderm; circulatory system, skin, skeleton, and internal organs
• D. endoderm; digestive system, lungs, urinary tract, and glands Answer: D Page Ref: 78 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: D

Rationale: During the period of the embryo, the endoderm becomes the digestive system, lungs, urinary tract, and glands. The endoderm is one of the primary germ layers that give rise to various internal organs in the developing embryo. It plays a crucial role in the formation of organs such as the digestive system, respiratory system, and glandular structures.

3. An inadequate diet during pregnancy can __________.

• A. lead to higher birth weight and greater brain weight
• B. reduce the risk of pregnancy-induced maternal diabetes
• C. distort the structure of the liver, kidney, and pancreas
• D. lead to fewer physical discomforts in the final weeks Answer: C Page Ref: 88 Skill Level: Understand Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: C

Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.

4. 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.

5. Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?

• A. regular sleep
• B. drowsiness
• C. irregular sleep
• D. quiet alertness

Correct answer: C

Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.
