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. A predisposition toward developing a disorder is termed a __________ .

A. Diathesis
B. Risk factor
C. Sufficient cause
D. Diathesis

Correct answer: A

Rationale: A predisposition toward developing a disorder is termed a diathesis. In this context, diathesis refers to an individual's susceptibility or predisposition to developing a disorder. A diathesis is not the same as a risk factor or a sufficient cause. A risk factor is a variable that increases the likelihood of developing a disorder but is not a predisposition itself. A sufficient cause is a factor that can produce the disorder on its own, not just a predisposition.

3. How do socioeconomic factors influence mental health?

A. Socioeconomic factors have no impact on mental health.
B. Socioeconomic factors are the primary determinants of mental health.
C. Socioeconomic factors are irrelevant to mental health.
D. Socioeconomic factors can exacerbate but not cause mental health issues.

Correct answer: B

Rationale: Socioeconomic factors are indeed primary determinants of mental health. These factors influence mental health by impacting access to resources, stress levels, and overall well-being. Choice A is incorrect as socioeconomic factors do have a significant impact on mental health. Choice C is incorrect as socioeconomic factors play a crucial role in mental health outcomes. Choice D is incorrect as socioeconomic factors can both exacerbate and cause mental health issues.

4. How do defense mechanisms contribute to psychopathology?

A. They do not contribute to psychopathology as they are healthy coping mechanisms.
B. They contribute to psychopathology by allowing individuals to avoid confronting painful realities.
C. Defense mechanisms have no connection to psychopathology.
D. Defense mechanisms are unconscious strategies that can lead to the development of psychopathology.

Correct answer: B

Rationale: The correct answer is B. Defense mechanisms contribute to psychopathology by allowing individuals to avoid confronting painful realities. This avoidance can prevent individuals from dealing with underlying issues, leading to the development or exacerbation of psychopathological conditions. Choice A is incorrect because while defense mechanisms may serve as coping mechanisms, they can also contribute to psychopathology when used excessively or inappropriately. Choice C is incorrect as defense mechanisms are indeed connected to psychopathology. Choice D is incorrect because defense mechanisms, when maladaptive, can contribute to psychopathology rather than being considered healthy coping strategies.

5. What is the traditional cutoff in diagnosing intellectual disability?

A. IQ score below 80
B. IQ score below 70
C. IQ score below 60
D. IQ score below 50

Correct answer: B

Rationale: The traditional cutoff for diagnosing intellectual disability is an IQ score below 70. An IQ score below 70 is generally considered as the threshold for diagnosing intellectual disability. Choices A, C, and D are incorrect as they do not reflect the commonly accepted cutoff point for diagnosing intellectual disability.
