This comprehensive NURS 6635 assessment is designed to strengthen understanding of
major psychiatric concepts, psychopathology, diagnostic reasoning, clinical assessment,
treatment principles, and psychopharmacologic management. The multiple-choice questions
assess foundational knowledge as well as interpretation, clinical application, decision-
making, safety, and professional judgment. Emphasis is placed on recognizing diagnostic
patterns, distinguishing disorders with overlapping features, selecting appropriate
interventions, understanding medication effects, and applying evidence-informed reasoning
to realistic patient situations. The explanations following each question reinforce the
underlying concepts and clarify why the selected response is the best answer. This material is
intended to support structured examination preparation and deeper understanding rather
than simple memorization.
Question 1. Which neurotransmitter is most strongly associated with the mesolimbic
pathway and the positive symptoms of schizophrenia?
A. Serotonin
B. Dopamine
C. Gamma-aminobutyric acid
D. Acetylcholine
Correct Answer: B. Dopamine
Explanation: Excessive dopaminergic activity in the mesolimbic pathway is associated with
positive symptoms of schizophrenia, including hallucinations, delusions, and disorganized
thinking.
,Question 2. A patient reports hearing a voice speaking when no one is present. Which
psychopathologic symptom is being demonstrated?
A. Delusion
B. Illusion
C. Hallucination
D. Depersonalization
Correct Answer: C. Hallucination
Explanation: A hallucination is a sensory perception occurring without an external stimulus.
Hearing a voice in the absence of an actual speaker represents an auditory hallucination.
Question 3. Which finding most strongly supports a diagnosis of major depressive
disorder?
A. Depressed mood or loss of interest accompanied by associated symptoms causing
functional impairment
B. Elevated mood occurring for several hours after receiving good news
C. Brief sadness following an interpersonal disagreement
D. Occasional fatigue without changes in mood or functioning
Correct Answer: A. Depressed mood or loss of interest accompanied by associated
symptoms causing functional impairment
Explanation: Major depressive disorder involves a clinically significant depressive episode
characterized by persistent mood or anhedonia along with additional symptoms that cause
distress or impairment.
Question 4. Which neurotransmitter system is particularly important in the regulation of
mood, anxiety, sleep, and appetite?
A. Serotonin
B. Acetylcholine
C. Histamine
D. Glutamate
Correct Answer: A. Serotonin
Explanation: Serotonin participates in the regulation of mood, anxiety, sleep, appetite, and
several other functions. Alterations in serotonergic signaling are relevant to multiple
psychiatric disorders.
,Question 5. A patient believes that the television broadcaster is sending personal
messages specifically to them. Which symptom is most consistent with this belief?
A. Thought blocking
B. Ideas of reference
C. Echolalia
D. Flight of ideas
Correct Answer: B. Ideas of reference
Explanation: Ideas of reference occur when an individual interprets neutral external events,
such as television programs or conversations, as having a specific personal meaning.
Question 6. Which feature best distinguishes a delusion from a hallucination?
A. A delusion involves an abnormal sensory perception
B. A hallucination involves a fixed false belief
C. A delusion is a fixed false belief despite contradictory evidence
D. A hallucination always occurs in schizophrenia
Correct Answer: C. A delusion is a fixed false belief despite contradictory evidence
Explanation: Delusions are disturbances of thought content involving fixed false beliefs.
Hallucinations are disturbances of perception and involve sensory experiences without an
external stimulus.
Question 7. Which component of the mental status examination assesses the patient's
ability to identify the current date, location, and personal identity?
A. Judgment
B. Orientation
C. Insight
D. Abstraction
Correct Answer: B. Orientation
Explanation: Orientation evaluates awareness of person, place, time, and sometimes
situation. It provides important information about cognition and possible neurologic or
psychiatric impairment.
Question 8. Which patient statement best demonstrates impaired insight?
, A. "I know the medication may cause dizziness."
B. "I understand that my family is concerned."
C. "I recognize that my symptoms have affected my work."
D. "There is absolutely nothing wrong with me even though I have been hospitalized
because of my behavior."
Correct Answer: D. "There is absolutely nothing wrong with me even though I have been
hospitalized because of my behavior."
Explanation: Insight refers to awareness and understanding of one's illness and its
consequences. Denial of an obvious psychiatric condition despite substantial evidence
suggests impaired insight.
Question 9. Which finding is most characteristic of mania?
A. Decreased energy and hypersomnia
B. Increased need for sleep with slowed thinking
C. Elevated or irritable mood with increased activity and decreased need for sleep
D. Persistent fear of a specific object
Correct Answer: C. Elevated or irritable mood with increased activity and decreased need
for sleep
Explanation: Mania involves a distinct period of abnormally elevated, expansive, or irritable
mood accompanied by increased energy and other characteristic symptoms such as
decreased need for sleep, pressured speech, and impulsivity.
Question 10. Which symptom is considered a negative symptom of schizophrenia?
A. Auditory hallucinations
B. Delusions
C. Avolition
D. Disorganized speech
Correct Answer: C. Avolition
Explanation: Negative symptoms reflect diminished normal functioning and include
