NR 547 Final Exam Comprehensive Study Guide 2026/2027: Comprehensive Knowledge Assessment and Review Guide: Advanced Test Bank, Detailed Practice Questions, Final Exam Preparation, and Complete Study Companion

A 34-year-old patient undergoes assessment using the Hamilton Depression Rating Scale (HAM-D) and scores 6. How should this result be interpreted in clinical practice? • A. Mild depression • B. Moderate depression • C. Severe depression • D. Normal (no depression) Correct Answer: D. Normal (no depression) Rationale: The HAM-D is a clinician-administered scale used to quantify the severity of depressive symptoms. A total score of 0–7 falls within the normal range, indicating no clinically significant depression. Scores of 8–16 represent mild depression, 17–23 moderate depression, and $ge$ 24 severe depression. A score of 6 reflects a subclinical symptom burden. Question 2 Which HAM-D score range specifically corresponds to moderate depression? • A. 0–7 • B. 8–16 • C. 17–23 • D. 24 and above Correct Answer: C. 17–23 Rationale: Standardized HAM-D severity bands are defined as: • 0–7: Normal (no depression) • 8–16: Mild depression • 17–23: Moderate depression • $ge$ 24: Severe depression Distinguishing between mild and moderate severity helps guide clinical decisionmaking regarding the initiation of combined pharmacotherapy and psychotherapy. Question 3 A clinician notes that the HAM-D is prone to overestimating depression severity in patients with concurrent medical illnesses. What is the primary reason for this limitation? • A. It ignores psychological symptoms entirely • B. It focuses heavily on somatic symptoms • C. It exclusively evaluates suicidal ideation • D. It is a patient self-administered screening tool Correct Answer: B. It focuses heavily on somatic symptoms Rationale: The HAM-D contains multiple items assessing physical/somatic complaints (e.g., insomnia, gastrointestinal issues, fatigue, weight loss). In medically ill populations, these symptoms frequently stem from physical disease (e.g., cancer, chronic kidney disease, endocrine dysfunction) rather than psychiatric pathology, leading to an artificially elevated depression score. Question 4 Which instrument is widely considered a superior alternative to the HAM-D for specifically tracking treatment response in clinical trial and outpatient settings? • A. Geriatric Depression Scale (GDS) • B. Mood Disorder Questionnaire (MDQ) • C. Montgomery–Åsberg Depression Rating Scale (MADRS) • D. Mini-Mental State Examination (MMSE) Correct Answer: C. Montgomery–Åsberg Depression Rating Scale (MADRS) Rationale: The MADRS was developed to be highly sensitive to treatment-induced changes over time. Unlike the HAM-D, the MADRS minimizes focus on somatic complaints and heavily emphasizes core psychological symptoms (such as apparent sadness, inner tension, and pessimistic thoughts), reducing confounding variables from physical illness. Question 5 A 72-year-old patient is screened using the 30-item Geriatric Depression Scale (GDS30) and scores 12. How is this score interpreted? • A. Normal • B. Mild depression • C. Moderate to severe depression • D. Severe depression only Correct Answer: B. Mild depression Rationale: On the GDS-30: • 0–9: Normal • 10–19: Mild depression • 20–30: Moderate to severe depression A score of 12 indicates mild depressive symptoms, warranting further clinical interview and targeted management while avoiding somatic symptom bias common in elderly medical populations. Question 6 Which design feature is characteristic of the Patient Health Questionnaire-9 (PHQ-9)? • A. Clinician-administered structured interview • B. Focuses on lifetime history of manic episodes • C. Directly maps onto the diagnostic criteria for Major Depressive Disorder • D. Excludes suicidal ideation to prevent patient distress Correct Answer: C. Based on DSM criteria for major depressive disorder Rationale: The PHQ-9 is a self-administered questionnaire directly modeled after the 9 diagnostic criteria for Major Depressive Disorder outlined in the DSM. Each item measures a specific criterion (including depressed mood, anhedonia, sleep disturbances, fatigue, and item #9: suicidal ideation) scored on a 0–3 scale based on frequency over the preceding two weeks. Question 7 A patient achieves a total score of 18 on the PHQ-9. Which depression severity level does this reflect? • A. Mild • B. Moderate • C. Moderately severe • D. Severe Correct Answer: C. Moderately severe Rationale: Standardized PHQ-9 severity bands are: • 0–4: Minimal • 5–9: Mild • 10–14: Moderate • 15–19: Moderately severe • 20–27: Severe Scores in the 15–19 range typically mandate active therapeutic intervention, usually combining psychotropic medication and structured psychotherapy. Question 8 Which PHQ-9 score represents the validated clinical cutoff threshold indicating possible clinical depression that requires further diagnostic evaluation? • A. $ge$ 5 • B. $ge$ 10 • C. $ge$ 15 • D. $ge$ 20 Correct Answer: B. $ge$ 10 Rationale: A PHQ-9 score of 10 or greater is the standard recommended cutoff point for identifying probable Major Depressive Disorder, offering optimal sensitivity and specificity across diverse patient populations. Scores $ge 10$ signal the need for a comprehensive clinical diagnostic interview. Question 9 Which clinical feature is directly assessed as part of Part 1 of the Mood Disorder Questionnaire (MDQ)? • A. Significant weight gain • B. Decreased appetite • C. Decreased need for sleep • D. Psychomotor retardation Correct Answer: C. Decreased need for sleep Rationale: The MDQ screens for bipolar spectrum disorders by evaluating lifetime manic and hypomanic symptoms. A classic cardinal symptom included in the tool is a decreased need for sleep (feeling fully rested after significantly fewer hours of sleep than usual). Symptoms like psychomotor retardation or appetite alterations are depressive features rather than manic criteria. Question 10 Which combination of parameters is strictly required for a positive screen on the Mood Disorder Questionnaire (MDQ)? • A. 5 symptoms + moderate functional impairment • B. 7 symptoms + simultaneous occurrence (clustering) + moderate/severe impairment • C. 10 symptoms + no functional impairment • D. Any 3 symptoms + family history of bipolar disorder Correct Answer: B. 7 symptoms + clustering + impairment Rationale: To meet the criteria for a positive MDQ screen, three criteria must be fulfilled concurrently: 1. Answering "Yes" to at least 7 of the 13 manic/hypomanic symptom items in Part 1. 2. Confirming that two or more of those symptoms occurred during the same time period (clustering) in Part 2. 3. Reporting moderate or severe functional impairment caused by those symptoms in Part 3. Question 11 For which condition does the MDQ exhibit its lowest sensitivity, frequently resulting in false negatives? • A. Bipolar I disorder • B. Bipolar II disorder • C. Mania with psychotic features • D. Severe manic episodes Correct Answer: B. Bipolar II disorder Rationale: The MDQ has strong sensitivity for Bipolar I disorder because full manic episodes produce marked impairment that patients remember. However, it is significantly less sensitive in detecting Bipolar II disorder and cyclothymia. Patients with Bipolar II experience hypomania, which is milder, often ego-syntonic, and less likely to be perceived or reported as causing functional impairment on a self-report tool. Question 12 What is the clinical definition of anhedonia? • A. Persistent excessive guilt and self-blame • B. Subjective loss of physical energy or profound fatigue • C. Diminished ability to experience pleasure from rewarding activities • D. Executive dysfunction resulting in impaired concentration Correct Answer: C. Diminished ability to experience pleasure Rationale: Anhedonia is defined as the inability to experience pleasure from activities that were previously rewarding or enjoyable (e.g., hobbies, social interactions, food, sex). It represents one of the two core diagnostic symptoms of a DSM-5 Major Depressive Episode (the other being persistent depressed mood). Question 13 What is the standard normal reference range for Thyroid-Stimulating Hormone (TSH) in non-medicated adult populations? • A. 0.1–1.0 mIU/L • B. 0.4–4.0 mIU/L • C. 5.0–10.0 mIU/L • D. 10.0–20.0 mIU/L Correct Answer: B. 0.4–4.0 Rationale: A reference range of 0.4 to 4.0 mIU/L is the standard physiological baseline for TSH in healthy adults. Because both hypothyroidism and hyperthyroidism closely mimic psychiatric syndromes (e.g., depression, panic disorder, psychomotor agitation), establishing baseline TSH levels is essential during initial psychiatric evaluation.
