1. Which of the following is a common effect of persistent discrimination?
- A. Increased happiness
- B. Greater intelligence and wisdom
- C. Cardiovascular reactivity
- D. Increased consciousness
Correct answer: C
Rationale: The correct answer is C: Cardiovascular reactivity. Persistent discrimination can have negative impacts on an individual's physical health, leading to increased cardiovascular reactivity. This can manifest as higher blood pressure, heart rate, and overall stress on the cardiovascular system. Choices A, B, and D are incorrect because persistent discrimination typically does not result in increased happiness, greater intelligence and wisdom, or increased consciousness. Instead, it often leads to detrimental effects on mental and physical health.
2. When Ryan was born, the hospital assessed his health with the Apgar scale, and the score was 5. What does this mean with respect to his breathing pattern?
- A. He was not in danger
- B. He needed help in establishing a breathing pattern
- C. He was in excellent condition
- D. He was in critical condition
Correct answer: B
Rationale: An Apgar score of 5 suggests that Ryan needed help establishing a regular breathing pattern after birth. Choice A is incorrect because a score of 5 indicates the need for assistance. Choice C is incorrect as an Apgar score of 5 does not reflect excellent condition. Choice D is incorrect as it signifies a critical condition, which is not the case with an Apgar score of 5.
3. How is pruning best defined?
- A. The process of eliminating unused synapses
- B. The process of synapse development
- C. The connection between neurons
- D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly
Correct answer: A
Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.
4. What is the term for the age of an unborn baby, usually dated from the first day of an expectant mother's last menstrual cycle?
- A. Mental age
- B. Chronological age
- C. Functional age
- D. Gestational age
Correct answer: D
Rationale: The correct answer is D, Gestational age. Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.
5. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?
- A. Babinski
- B. Palmar
- C. Darwinian
- D. Moro
Correct answer: D
Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.
