Psychopathology and Diagnostic
Reasoning | Actual Q&A with Rationale
(NRNP6635 Exam 1) | Walden University
1. When conducting a diagnostic interview, which approach is most effective for eliciting a
comprehensive history of a patient’s symptoms?
A. Using strictly closed-ended questions to maintain a structured timeline.
B. Focusing exclusively on the chief complaint to ensure the session remains focused.
C. Utilizing open-ended questions to allow the patient to describe their experience in their
own words.
D. Interrupting frequently to clarify specific medical details as they arise.
Answer: C
Rationale: Open-ended questions encourage patients to provide narrative responses,
which often reveal nuanced information about their psychopathology. This method fosters
a collaborative therapeutic alliance and allows the clinician to observe the patient’s
spontaneous thought process. Effective diagnostic reasoning begins with a broad
understanding of the patient’s subjective experience before narrowing down to specific
criteria.
,2. A 24-year-old patient presents with a two-week history of depressed mood, significant
weight loss, and insomnia. To meet the DSM-5 criteria for Major Depressive Disorder, which
additional symptom must be considered if the patient does not report depressed mood?
A. Recurrent thoughts of death or suicidal ideation.
B. Psychomotor agitation observed by family members.
C. Anhedonia or a marked loss of interest in previously enjoyed activities.
D. Feelings of worthlessness or excessive guilt.
Answer: C
Rationale: The DSM-5-TR mandates that at least one of the two core symptoms—
depressed mood or loss of interest/pleasure—must be present for a diagnosis of Major
Depressive Disorder. Anhedonia represents a significant biological and psychological
marker of depressive states. Without one of these two symptoms, the clinician must
explore other potential diagnostic avenues for the patient’s distress.
3. During a Mental Status Examination (MSE), the clinician notes that the patient’s emotional
expression changes rapidly and lacks stability. Which term best describes this finding?
A. Blunted affect
B. Constricted affect
C. Labile affect
D. Flat affect
,Answer: C
Rationale: Labile affect refers to quick, significant swings in emotional expression that are
often out of proportion to the context. This finding is frequently associated with bipolar
disorders, certain personality disorders, or organic brain syndromes. Distinguishing
between mood, which is the internal emotional state, and affect, the external expression, is
a fundamental skill in psychiatric assessment.
4. A patient exhibits a pattern of grandiose thinking, a decreased need for sleep, and flight of
ideas for the past 8 days. They have never required hospitalization for these symptoms. What
is the most likely diagnosis?
A. Cyclothymic Disorder
B. Bipolar I Disorder
C. Bipolar II Disorder
D. Major Depressive Disorder with anxious distress
Answer: B
Rationale: A manic episode is defined by a period of at least one week of abnormally
elevated or irritable mood and increased energy. Since the symptoms lasted 8 days and
included grandiosity and flight of ideas, it meets the threshold for Mania, which confirms a
Bipolar I diagnosis. Bipolar II requires a hypomanic episode (at least 4 days) and a history
of major depression, but a full manic episode automatically qualifies for Bipolar I.
, 5. Which of the following neurotransmitter pathways is primarily implicated in the
development of positive symptoms in Schizophrenia, such as hallucinations and delusions?
A. Mesocortical pathway
B. Nigrostriatal pathway
C. Mesolimbic pathway
D. Tuberoinfundibular pathway
Answer: C
Rationale: Overactivity in the mesolimbic dopamine pathway is theorized to be
responsible for the ‘positive’ symptoms of schizophrenia. This pathway projects from the
ventral tegmental area to the limbic system, mediating reward and emotional salience.
Antipsychotic medications typically target D2 receptors in this area to reduce psychotic
symptoms.
6. In the differential diagnosis of Delirium versus Dementia, which clinical feature is most
characteristic of Delirium?
A. Gradual, progressive decline in memory.
B. Acute onset with fluctuating levels of consciousness.
C. Stable cognitive deficits throughout the day.
D. Preserved attention and orientation until late stages.
Answer: B
