1. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?

A. Embryo
B. DNA
C. Fetus
D. Zygote

Correct answer: D

Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.

2. What role do genetic predispositions play in the development of mental disorders?

A. Genetic predispositions solely determine the development of mental disorders.
B. Genetic predispositions play a role but are not solely responsible for the development of mental disorders.
C. Genetic predispositions have no influence on mental disorders.
D. Genetic predispositions guarantee the development of mental disorders.

Correct answer: B

Rationale: Genetic predispositions are indeed a factor in the development of mental disorders, but they are not the sole determining factor. While genetics can predispose individuals to certain conditions, environmental factors, lifestyle choices, and life experiences also play a significant role. Choice A is incorrect because mental disorders are influenced by a combination of genetic and environmental factors. Choice C is incorrect as genetic predispositions do have an impact on mental health. Choice D is incorrect as genetic predispositions do not guarantee the development of mental disorders, as other factors also contribute to their onset.

3. What is the biopsychosocial model?

A. A model that integrates biological, psychological, and social factors in understanding mental disorders.
B. A model that emphasizes the interaction between biological and psychological factors, excluding social influences.
C. The biopsychosocial model emphasizes only psychological factors in mental disorders.
D. The biopsychosocial model is a purely biological approach to mental health.

Correct answer: A

Rationale: The biopsychosocial model is a comprehensive approach that considers biological, psychological, and social factors in understanding mental disorders. Choice A is correct because it accurately describes how this model integrates these three factors. Choice B is incorrect as it excludes social influences from the model. Choice C is incorrect because it states that the model only emphasizes psychological factors, which is not true. Choice D is incorrect as it suggests that the model is purely biological, which is also inaccurate.

4. Deferred imitation of a caregiver's behavior shows that toddlers have the capacity to form?

A. Short-term memory
B. Working memory
C. Core memories
D. Long-term memory

Correct answer: D

Rationale: Deferred imitation refers to the ability of toddlers to observe and replicate behaviors after a period of time, indicating the formation of long-term memories. This process involves storing information for an extended period and recalling it at a later time. This capacity is not attributed to short-term memory (choice A), which is more temporary in nature and has limited storage capacity. Working memory (choice B) involves the temporary storage and manipulation of information for cognitive tasks, not necessarily the long-term retention of behaviors. Core memories (choice C) are typically associated with emotional or significant events rather than the replication of observed behaviors. Therefore, the correct answer is choice D, as deferred imitation demonstrates toddlers' capability to form long-term memories by replicating behaviors observed earlier.

5. Which of the following is true about subjective distress?

A. All individuals with mental illness experience some degree of distress
B. Distress is the only criterion in diagnosing abnormality
C. Its presence is enough for a clinician to determine if someone has a mental illness
D. Some individuals with a mental disorder may not experience subjective distress

Correct answer: D

Rationale: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.
