ATI RN

Psychological Exam

1. 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.

2. Roger has suffered a major brain injury. As a result, he is unable to speak fluently, tends to mispronounce words, and speaks haltingly. For instance, he says 'wat' instead of 'watch' and 'tot' instead of 'talk.' What is the diagnosis?

A. Agnosia
B. Spatial neglect
C. Broca's aphasia
D. Prosopagnosia

Correct answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

3. 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.

4. What is the diathesis-stress model of psychopathology?

A. The idea that stress is the primary cause of psychopathology.
B. A model that focuses solely on genetic predispositions.
C. A theory that involves only environmental factors in the development of disorders.
D. A person must have both a vulnerability for a disorder and exposure to stressors to develop the disorder.

Correct answer: D

Rationale: The diathesis-stress model of psychopathology posits that individuals must have a vulnerability or predisposition to a disorder (diathesis) and be exposed to stressful environmental factors for the disorder to manifest. This model emphasizes the interaction between genetic or biological vulnerabilities (diathesis) and environmental stressors. Choice A is incorrect because the model does not suggest that stress is the sole cause of psychopathology. Choice B is incorrect as the model considers both genetic predispositions and environmental stressors. Choice C is incorrect because the diathesis-stress model acknowledges the role of both genetic and environmental factors in the development of disorders.

5. During which span of months or years is a child particularly responsive to specific forms of experience or influenced by their absence?

A. Nonnormative influences
B. Normative age-graded influence
C. Normative history-graded influence
D. Sensitive period

Correct answer: D

Rationale: The correct answer is 'Sensitive period.' A sensitive period refers to a specific span of time during development when a child is especially responsive to certain experiences. This period allows for optimal development in specific areas. Nonnormative influences (Choice A) are events that are irregular and unpredictable, while normative age-graded influences (Choice B) are typical events that occur in a similar manner for most people in a specific age group. Normative history-graded influences (Choice C) are events that most people in a specific culture or cohort experience at the same time.
