Chapter 2 Psych Nursing (All Solved)

1. The nurse is assessing a patient suffering a head injury as a result of an altercation with two other individuals. The patient has difficulty accurately reporting the events of the altercation and appears very emotional during the assessment. The nurse suspects which part of the brain received the greatest amount of injury? A) Cerebrum B) Cerebellum C) Medulla D) Amygdala Correct Ans: A Feedback: The frontal lobes of the cerebrum control the organization of thought, body movement, memories, emotions, and moral behavior. The cerebellum is located below the cerebrum and is the center for coordination of movements and postural adjustments. The medulla, located at the top of the spinal cord, contains vital centers for respiration and cardiovascular functions. The hippocampus and amygdala are involved in emotional arousal and memory. 2. An abnormality of which of the following structures of the cerebrum would be associated with schizophrenia? A) Parietal lobes B) Frontal lobe C) Occipital lobe D) Temporal lobes Correct Ans: B Feedback: Abnormalities in the frontal lobes are associated with schizophrenia, attention deficit hyperactivity disorder (ADHD), and dementia. The parietal lobes interpret sensations of taste and touch and assist in spatial orientation. The temporal lobes are centers for the senses of smell and hearing and for memory and emotional expression. The occipital lobe assists in coordinating language generation and visual interpretation, such as depth perception. 3. A patient with bipolar disorder asks the nurse, ìWhy did I get this illness? I don't want to be sick.î The nurse would best respond with, A) ìPeople who develop mental illnesses often had very traumatic childhood experiences.î B) ìThere is some evidence that contracting a virus during childhood can lead to mental disorders.î C) ìSometimes people with mental illness have an overactive immune system.î D)ìWe don't fully understand the cause, but mental illnesses do seem to run in families.î Correct Ans: D Feedback: Current theories and studies indicate that several mental disorders may be linked to a specific gene or combination of genes, but that the source is not solely genetic; nongenetic factors also play important roles. A compromised immune system could contribute to the development of a variety of illnesses, particularly in populations already genetically at risk. Maternal exposure to a virus during critical fetal development of the nervous system may contribute to mental illness.
