Question 1 of 5
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?
Correct Answer: A
Rationale: The frontal lobes of the cerebrum control the organization of thought, body movement, memories, emotions, and moral behavior. The cerebellum is the center for coordination of movements and postural adjustments. The medulla contains vital centers for respiration and cardiovascular functions. The amygdala is involved in emotional arousal and memory.
Question 2 of 5
An abnormality of which of the following structures of the cerebrum would be associated with schizophrenia?
Correct Answer: B
Rationale: Abnormalities in the frontal lobes are associated with schizophrenia, attention deficit hyperactivity disorder (ADH
D), 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.
Question 3 of 5
A patient with bipolar disorder asks the nurse, 'Why did I get this illness? I don't want to be sick.' The nurse would best respond with,
Correct Answer: D
Rationale: 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. Traumatic childhood experiences, viral infections, and immune system activity may contribute to mental illness in genetically predisposed individuals, but these are not definitive causes.
