Chapter 2. Biological Implications Multiple Choice 1.A depressed client states, I have a chemical imbalance in my brain. I have no control over my behavior. Medications are my only hope to feel normal again. Which nursing response is appropriate?1. Medications only address biological factors. Environmental and interpersonal factors must also be considered.2. Because biological factors are the sole cause of depression, medications will improve your mood.3. Environmental factors have been shown to exert the most influence in the development of depression.4. Researchers have been unable to demonstrate a link between nature (biology and genetics) and nurture (environment). ANS: 1 Rationale: 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. Cognitive Level: Analysis Integrated Process: Implementation 2.A client diagnosed with major depressive disorder asks, What part of my brain controls my emotions? Which nursing response is appropriate? 1. The occipital lobe governs perceptions, judging them as positive or negative.2. The parietal lobe has been linked to depression.3. The medulla regulates key biological and psychological activities.4. The limbic system is largely responsible for ones emotional state. ANS: 4 Rationale: The nurse should explain to the client that the limbic system is largely responsible for ones emotional state. This system if often called the emotional brain and is associated with feelings, sexuality, and social behavior. 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. Cognitive Level: Application Integrated Process: Implementation 3.Which part of the nervous system should a nurse identify as playing a major role during stressful situations? 1. Peripheral nervous system 2. Somatic nervous system 3. Sympathetic nervous system 4. Parasympathetic nervous system ANS: 3 Rationale: 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. Cognitive Level: Comprehension Integrated Process: Assessment 4. Which client statement reflects an understanding of circadian rhythms in psychopathology?1. When I dream about my mothers horrible train accident, I become hysterical. 2. I get really irritable during my menstrual cycle.3. Im a morning person. I get my best work done before noon. 4.Every February, I tend to experience periods of sadness. ANS: 3 Rationale: 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. Cognitive Level: Analysis Integrated Process: Evaluation 5.Which types of adoption studies should a nurse recognize as providing useful information for the psychiatric community? 1. Studies in which children with mentally ill biological parents are raised by adoptive parents who were mentally healthy.2. Studies in which children with mentally healthy biological parents are raised by adoptive parents who were mentally ill. 3. Studies in which monozygotic twins from mentally ill parents were raised separately by different adoptive parents.4. Studies in which monozygotic twins were raised together by mentally ill biological parents. 5.All of the above. ANS: 5 Rationale: 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.
