1. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?

• A. Autonomic
• B. Sympathetic
• C. Parasympathetic
• D. Somatic

Correct answer: B

Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.

2. In a breech presentation, how is the infant positioned for delivery?

• A. Is too large to be delivered vaginally.
• B. Is delivered feet or bottom first.
• C. Is delivered head first.
• D. Appears face down.

Correct answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.

3. Down syndrome is caused by ________.

• A. a chemical imbalance.
• B. a gene on the X chromosome.
• C. possessing an extra X chromosome.
• D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not by a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an additional chromosome 21 disrupts the normal course of development and leads to the characteristics associated with Down syndrome.

4. How does the diathesis-stress model explain the onset of mental disorders?

• A. Stress alone is sufficient to cause mental disorders.
• B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
• C. Only genetic factors cause mental disorders.
• D. Environmental stressors alone can cause mental disorders.

Correct answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.

5. Franklin wakes up in a homeless shelter in another town. He doesn't know where he is or how he got there, and he's confused when people say he has been calling himself Anthony. This is most likely an episode of dissociative?

• A. Amnesia
• B. Dissociative fugue
• C. Wandering
• D. Flight of ideas

Correct answer: B

Rationale: The correct answer is B, Dissociative fugue. In the scenario described, Franklin experiencing memory loss, travel to another town, assuming a new identity (calling himself Anthony) aligns with dissociative fugue. Amnesia (Choice A) involves memory loss without the additional aspects of travel and assuming a new identity. Wandering (Choice C) is vague and does not encompass the complete set of symptoms described. Flight of ideas (Choice D) is a symptom of conditions like mania, not dissociative disorders.
