Question 1 of 5
A nurse is involved in gathering information about the inheritance of mental disorders using population genetics. Which of the following would the nurse be least likely to be evaluating?
Correct Answer: C
Rationale: Population genetics studies inheritance patterns using concordance rates, first-degree relative occurrences, and adoption studies to isolate genetic vs. environmental factors. Risk factor analysis, while relevant to epidemiology, is less specific to genetic inheritance studies.
Question 2 of 5
A nurse is reading a journal article about psychoneuroimmunology. Which information would the nurse most likely find? Select all that apply.
Correct Answer: B,D,E
Rationale: Psychoneuroimmunology studies interactions between the nervous, endocrine, and immune systems. Hypothalamic-pituitary-thyroid axis disruption (
B), hypothalamic damage leading to immune dysfunction (
D), and circadian rhythm interruptions (E) are relevant, as they link stress and brain function to immune responses. Neurotoxins (
A) are less central, and natural killer cells are not static (
C) but increase with stress.
Question 3 of 5
A patient is scheduled for a challenge test. Which of the following would the nurse include when explaining this test to the patient?
Correct Answer: A
Rationale: A challenge test involves administering a substance (e.g., a drug) to provoke symptoms for diagnostic purposes. Electrodes and electrical impulses relate to EEGs, and strobe lights are used in evoked potential tests, not challenge tests.
Question 4 of 5
A patient with depression tells the nurse that he is to have a test that involves the recording of an electroencephalogram (EEG) throughout the night. The nurse most likely identifies this testing as which of the following?
Correct Answer: B
Rationale: Polysomnography involves overnight EEG recording to assess sleep patterns, often used in depression to evaluate sleep disturbances. Sleep deprivation EEG requires staying awake, evoked potentials test sensory responses, and fMRI measures brain activity, not sleep.
Question 5 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.
