Chapter 2: Biological Implications Answer Section MULTIPLE CHOICE 1. ANS: 1 Chapter: Chapter 2, Biological Implications Objective: Recognize various theorized influences in the development of psychiatric disorders including brain physiology, genetics, endocrine function, immune system, and psychosocial, and environmental factors. Page: 15–19 Headings: The Parietal Lobes, The Occipital Lobes, Limbic System, Medulla Integrated Processes: Teaching and Learning Client Need: Psychosocial Integrity Cognitive Level: Analysis [Analyzing] Concept: Mood Difficulty: Easy 1 2 3 4 Feedback The nurse should advise the client that medications address biological factors, but there are other factors that affect mood. The nurse should educate the client on environmental and interpersonal factors that can lead to depression. The statement is false because biological factors are not the sole cause of depression. It is false that environmental factors have been shown to exert the most influence in the development of depression. Researchers have demonstrated a link between nature and nurture. PTS: 1 2. ANS: 4 CON: Mood Chapter: Chapter 2, Biological Implications Objective: Identify gross anatomical structures of the brain and describe their functions. Page: 16 Headings: The Nervous System: An Anatomical Review > The Brain Integrated Processes: Teaching and Learning Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Application [Applying] Concept: Mood Difficulty: Moderate 1 2 3 4 Feedback The occipital lobes are the area of visual reception and interpretation. Somatosensory input (touch, taste, temperature, etc.) occurs in the parietal lobes. The medulla contains vital centers that regulate heart rate and reflexes. The nurse should explain to the client that the limbic system is largely responsible for one’s emotional state. This system is often called the “emotional brain” and is associated with feelings, sexuality, and social behavior. PTS: 1 3. ANS: 3 CON: Mood Chapter: Chapter 2, Biological Implications Objective: Discuss the physiology of neurotransmission in the central nervous system. Page: 21 Heading: Autonomic Nervous System Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Comprehension [Understanding] Concept: Mood Difficulty: Moderate 1 2 3 4 Feedback The peripheral nervous system does not play a major role during stressful situations. The somatic nervous system is part of the peripheral nervous system. The nurse should identify that the sympathetic nervous system plays a major role during stressful situations. The sympathetic nervous system prepares the body for the fight-or-flight response. The parasympathetic nervous system is dominant when an individual is in a nonstressful state. PTS: 1 4. ANS: 3 CON: Mood Chapter: Chapter 2, Biological Implications Objective: Discuss the physiology of neurotransmission in the central nervous system. Page: 29–30 Heading: Circadian Rhythms Integrated Processes: Teaching and Learning Client Need: Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Analysis [Analyzing] Concept: Sleep and Rest Difficulty: Moderate 1 2 3 4 Feedback This statement does not indicate understanding of circadian rhythms. The menstrual cycle is not affected by the circadian rhythm. By stating, “I am a morning person,” the client demonstrates an understanding that circadian rhythms may influence a variety of regulatory functions, including the sleep-wake cycle, regulation of body temperature, and patterns of activity. Most humans follow a 24-hour cycle that is largely affected by lightness and darkness. Experiencing periods of sadness is not indicative of the circadian rhythm. PTS: 1 5. ANS: 5 CON: Sleep and Rest Chapter: Chapter 2, Biological Implications Objective: Discuss the implications of psychobiological concepts to the practice of psychiatric/mental health nursing. Page: 31 Heading: Genetics > Adoptions Studies Client Need: Physiological Integrity: Physiological Adaptation Concept: Evidence-based Practice Cognitive Level: Analysis [Analyzing] Integrated Processes: Teaching and Learning Difficulty: Moderate 1 2 3 4 5 Feedback This type of adoption study can provide information on children with mentally ill biological parents who are raised by adoptive parents who are mentally healthy parents. This type of adoption study can provide information on children with mentally healthy biological parents who are raised by adoptive parents who are mentally ill. This type of adoption study provides important information on monozygotic twins from mentally ill parents who were raised separately by different adoptive parents. This type of adoption study provides important information on monozygotic twins who were raised together by mentally ill biological parents. The nurse should determine that all of the studies could possibly benefit the psychiatric community. The studies may reveal research findings relating genetic links to mental illness. Adoption studies allow comparisons to be made of the influences of the environment versus genetics. PTS: 1 6. ANS: 2 CON: Evidence-based Practice Chapter: Chapter 2, Biological Implications Objective: Discuss the influence of psychological factors on the immune system. Page: 31 Heading: Psychoneuroimmunology > Implications of the Immune System in Psychiatric Illness Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Application [Applying] Concept: Stress Difficulty: Moderate 1 Feedback Neuroendocrinology is the study of the interaction between the nervous system and the endocrine system. 2 3 4 Psychoneuroimmunology is the branch of medicine that studies the effects of social and psychological factors on the functioning of the immune system. Studies of the biological response to stress hypothesize that individuals become more susceptible to physical illness following exposure to stressful stimuli. Diagnostic testing assists in diagnosing. Neurophysiology is the physiology of the nervous system. PTS: 1 7. ANS: 3 CON: Stress Chapter: Chapter 2, Biological Implications Objective: Describe the role of neurotransmitters in the central nervous system.

A junction between two neurons is a synapse. PTS: 1 8. ANS: 2 CON: Mood Chapter: Chapter 2, Biological Implications Objective: Describe the role of neurotransmitters in the central nervous system. Page: 21 Heading: The Nervous System: An Anatomical Review > Neurotransmitters Integrated Processes: Teaching and Learning Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Comprehension [Understanding] Concept: Mood Difficulty: Moderate 1 2 Feedback Regeneration is incorrect wording to describe this process. The nursing instructor should explain that the process by which neurotransmitters are released into the synaptic cleft and returned to the presynaptic neuron is termed reuptake. Reuptake is the process by which neurotransmitters are stored for reuse. 3 4 Recycling is incorrect wording to describe this process. Retransmission is incorrect wording to describe this process. PTS: 1 9. ANS: 4 CON: Mood Chapter: Chapter 2, Biological Implications Objective: Describe the role of neurotransmitters in the central nervous system. Page: 21 Heading: Monoamines > Norepinephrine Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Comprehension [Understanding] Concept: Mood Difficulty: Moderate 1 2 3 4 Feedback Acetylcholine functions include pain, arousal, and pain perception. Dopamine functions include regulation of movement and coordination. Serotonin plays a role in sleep, libido, and appetite. The nurse should associate the neurotransmitter norepinephrine with the fight-or-flight response. Norepinephrine produces activity in the sympathetic postsynaptic nerve terminal and is associated with the regulation of mood, cognition, perception, locomotion, and sleep and arousal. PTS: 1 10. ANS: 2 CON: Mood Chapter: Chapter 2: Biological Implications Objective: Describe the role of neurotransmitters in the central nervous system. Page: 21 Heading: Monoamines > Norepinephrine Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Application [Applying] Concept: Mood Difficulty: Moderate 1 2 3 4 Feedback Serotonin plays a role in sleep, libido, and appetite. The nurse should expect that elevated dopamine levels might be an attributing factor to the client’s current level of functioning. Dopamine functions include regulation of movements and coordination, emotions, and voluntary decision-making ability. GABA prevents postsynaptic excitation. Histamine mediates allergic and inflammatory reactions. PTS: 1 CON: Mood 11.
