Chapter 8 : Biologic Foundations of Psychiatric Nursing Questions
Question 1 of 5
A group of nursing students are reviewing the role of serotonin in psychiatric disorders. The students demonstrate a need for additional study when they identify which disorder as being associated with its dysfunction?
Correct Answer: D
Rationale: Serotonin dysregulation is strongly associated with depression, OCD, and panic disorder. Schizophrenia is primarily linked to dopamine dysregulation, so identifying it as serotonin-related indicates a misunderstanding.
Question 2 of 5
When describing neuronal transmission, an instructor describes the area where the electrical intracellular signal becomes a chemical one. The instructor is describing which of the following?
Correct Answer: B
Rationale: The synaptic cleft is where the electrical signal (action potential) triggers the release of neurotransmitters, converting the signal to a chemical one. The soma is the cell body, the terminal releases neurotransmitters, and the receptor site binds them.
Question 3 of 5
A nurse is teaching a medication class to a group of psychiatric patients. One of them asks the nurse why he has so much more trouble learning now when he?s in his 60s than he did when he was younger. Which of the following concepts would the nurse integrate into the response?
Correct Answer: C
Rationale: Neuroplasticity refers to the brain?s ability to adapt and form new neural connections, which declines with age, impacting learning and memory. The nurse would explain that reduced neuroplasticity in older age makes learning more challenging. The extrapyramidal motor system affects movement, the amygdala regulates emotions, and psychoneuroimmunology involves immune-brain interactions, none of which directly address learning difficulties.
Question 4 of 5
Which of the following would a nursing instructor identify when describing the area of the brain involved with verbal language function, including areas for both receptive and expressive speech?
Correct Answer: D
Rationale: The left hemisphere is primarily responsible for verbal language functions, including Broca?s area (expressive speech) and Wernicke?s area (receptive speech). The right hemisphere handles nonverbal functions, the parietal lobe processes sensory information, and the occipital lobe is involved in vision.
Question 5 of 5
A nurse is developing a plan of care for a patient experiencing expressive aphasia. The nurse incorporates knowledge that the patient most likely has sustained damage to which of the following?
Correct Answer: B
Rationale: Expressive aphasia, difficulty producing speech, is associated with damage to Broca?s area in the frontal lobe. The postcentral gyrus processes sensory input, the basal ganglia regulate movement, and the hippocampus is involved in memory, none of which directly cause expressive aphasia.
