A 25-year-old woman experiences intrusive memories and avoidance of vehicles 2 weeks after surviving a severe car crash.
A 32-year-old man reports excessive, uncontrollable worry about his health, finances, and job performance occurring most days for the past 8 months.
A 28-year-old woman experiences intense fear, palpitations, and shortness of breath exclusively when encountering spiders; this has been present since childhood.
A 40-year-old combat veteran reports hypervigilance, emotional numbing, and nightmares for the past 2 years since returning from deployment.

Matches

Show answer & explanation

Answer

Match the 2-week trauma symptoms to acute stress disorder, the 8-month multiple-domain worry to generalized anxiety disorder, the childhood spider fear to specific phobia, and the 2-year trauma symptoms to post-traumatic stress disorder.
Each diagnosis has specific criteria based on symptom duration and trigger. Acute stress disorder requires trauma symptoms lasting between 3 days and 1 month. Post-traumatic stress disorder requires trauma symptoms persisting for more than 1 month. Generalized anxiety disorder requires excessive worry about multiple issues for at least 6 months. Specific phobia requires a marked, disproportionate fear of a specific object or situation.

Step-by-Step Solution

1
Analyze the presentation involving the car crash survivor.
The trauma symptoms have only been present for 2 weeks.
Differentiating acute stress disorder from post-traumatic stress disorder requires checking the 1-month threshold.
2
Analyze the presentation involving the man with multiple worries.
He has non-specific, widespread worry for over 6 months.
Excessive worry across multiple domains meeting the 6-month timeline confirms generalized anxiety disorder.
3
Analyze the presentation involving the fear of spiders.
The anxiety is restricted solely to spiders and is chronic.
Anxiety triggered by a single specific object points to a specific phobia.
4
Analyze the presentation involving the combat veteran.
The trauma symptoms have persisted for 2 years.
Symptoms lasting beyond 1 month after a trauma confirm post-traumatic stress disorder.

Match each clinical vignette describing a patient's pervasive interpersonal and behavioral patterns to the most likely personality disorder diagnosis.

Click a left item, then click its matching right item

Items

A 35-year-old accountant is continually late submitting reports due to repeatedly checking them for formatting errors. He refuses to let his assistant help, insisting his method is the only correct one, and sees no issue with his behavior.
A 28-year-old actor frequently belittles his peers and expects constant praise for his 'unique talent.' He manipulates friends to advance his career and lacks empathy, though he has no history of unlawful behavior.
A 41-year-old man lives alone, collects crystals he believes offer protection from 'negative energy fields,' and feels intensely anxious even around familiar people because he suspects they are secretly plotting against him.
A 24-year-old technician eats lunch alone in her car every day. She desperately wants to join her colleagues in the breakroom but is convinced they will find her boring and harshly judge her every word.
A 30-year-old programmer works the night shift and has no friends by choice. He describes himself as indifferent to the praise or criticism of his supervisor and shows a restricted range of emotional expression.

Matches

Show answer & explanation

Answer

The vignettes match as follows: The rigid accountant has Obsessive-Compulsive Personality Disorder; the grandiose actor has Narcissistic Personality Disorder; the eccentric crystal collector has Schizotypal Personality Disorder; the fearful but lonely technician has Avoidant Personality Disorder; and the indifferent programmer has Schizoid Personality Disorder.
Each personality disorder is defined by specific, pervasive patterns of inner experience and behavior. Obsessive-Compulsive Personality Disorder is marked by rigid perfectionism; Narcissistic Personality Disorder by grandiosity and lack of empathy; Schizotypal Personality Disorder by cognitive/perceptual distortions and eccentricities; Avoidant Personality Disorder by extreme sensitivity to negative evaluation; and Schizoid Personality Disorder by detachment from social relationships and restricted emotional expression.

Step-by-Step Solution

1
Analyze the first vignette focusing on perfectionism and control.
The accountant exhibits ego-syntonic rigidity and inability to delegate, matching Obsessive-Compulsive Personality Disorder.
Differentiating ego-syntonic personality traits from ego-dystonic obsessions/compulsions is required to identify Obsessive-Compulsive Personality Disorder.
2
Evaluate the second vignette regarding grandiosity and exploitation.
The actor displays an intense need for admiration and lack of empathy without illegal behavior, matching Narcissistic Personality Disorder.
Distinguishing Narcissistic Personality Disorder from Antisocial Personality Disorder relies on the presence of grandiosity and the absence of pervasive criminality.
3
Assess the third vignette describing eccentricities and paranoia.
The crystal collector exhibits magical thinking and paranoid social anxiety, aligning with Schizotypal Personality Disorder.
These positive psychotic-like symptoms separate Schizotypal Personality Disorder from other Cluster A disorders.
4
Examine the fourth vignette regarding social isolation and fear of judgment.
The technician desires relationships but avoids them due to fear of rejection, matching Avoidant Personality Disorder.
The strong desire for social contact differentiates Avoidant Personality Disorder from Schizoid Personality Disorder.
5
Analyze the fifth vignette focusing on voluntary isolation.
The programmer is indifferent to others and lacks a desire for relationships, matching Schizoid Personality Disorder.
Voluntary social withdrawal without paranoid fears or desire for connection is the core of Schizoid Personality Disorder.

Key Concept

Differentiating personality disorders requires identifying the underlying motivations for behavior (e.g., reason for social isolation, type of grandiosity, ego-syntonic vs. ego-dystonic nature of symptoms).
Question 723Question →

Review the following patient summaries describing complex depressive presentations. Match each clinical profile with the most appropriate next step in pharmacologic or somatic management.

Items

An 82-year-old male with 2 months of severe depressed mood who now refuses all food and liquids, stating his intestines have completely rotted away.
A 22-year-old female with anhedonia and hypersomnia whose history includes a distinct 4-day episode of racing thoughts, decreased need for sleep, and impulsive spending that did not impair functioning.
A 35-year-old female with chronic depression, prominent mood reactivity, hyperphagia, and severe rejection sensitivity who has failed sequential trials of fluoxetine, venlafaxine, and nortriptyline.
A 45-year-old male whose depressed mood and active suicidality resolved on maximum-dose sertraline, but who currently struggles with profound residual daytime fatigue, apathy, and cognitive slowing.

Matches

Show answer & explanation

Answer

Match each clinical profile to its targeted therapy based on specific symptom clusters, psychiatric comorbidities, and urgency: the actively starving psychotic patient requires ECT; the patient with past hypomania requires quetiapine for bipolar II depression; the treatment-resistant patient with atypical features benefits from an MAOI; and the patient with residual SSRI-induced apathy requires bupropion augmentation.
Each pairing tests a specific, advanced nuance in the algorithmic treatment of depressive disorders. Patients with severe psychotic depression and refusal to eat require immediate somatic intervention (ECT) to prevent death from dehydration or starvation. Patients presenting with depression who have a history of 4 or more days of elevated mood and energy meet criteria for Bipolar II disorder; they must be treated with bipolar-specific agents (e.g., quetiapine, lurasidone) rather than traditional antidepressants to prevent mood destabilization. Treatment-resistant depression with classic atypical features (mood reactivity, hyperphagia, leaden paralysis, rejection sensitivity) shows unique responsiveness to monoamine oxidase inhibitors (MAOIs) like phenelzine, which remain a high-yield salvage therapy for this subtype. Finally, patients who achieve remission of core depressive and suicidal symptoms on an SSRI but suffer from residual fatigue, cognitive slowing, or apathy benefit from the targeted addition of bupropion, an NDRI that addresses these specific dopaminergic/noradrenergic deficits.

Step-by-Step Solution

1
Analyze the 82-year-old male's presentation.
Diagnosis is major depressive disorder with psychotic features (somatic delusion) and life-threatening inanition.
Severe starvation in an elderly patient is a psychiatric emergency where waiting weeks for oral pharmacotherapy to take effect is fatal, necessitating immediate somatic therapy (ECT).
2
Analyze the 22-year-old female's presentation.
Diagnosis is Bipolar II disorder based on the current depressive episode and a distinct past hypomanic episode (4 days of elevated energy/impulsivity without severe impairment).
Recognizing past hypomania is critical to avoid SSRI-induced mood destabilization and dictates the use of a bipolar-approved agent like quetiapine.
3
Analyze the 35-year-old female's presentation.
Diagnosis is treatment-resistant depression with atypical features.
Patients with atypical depression (mood reactivity, hyperphagia, leaden paralysis, rejection sensitivity) who fail standard antidepressants have a uniquely high response rate to MAOIs.
4
Analyze the 45-year-old male's presentation.
Diagnosis is MDD with a partial response to SSRI therapy and specific residual target symptoms (fatigue, anergia).
Bupropion targets dopamine and norepinephrine, directly alleviating fatigue and cognitive slowing without risking serotonin syndrome when added to an SSRI.

Key Concept

Advanced tailoring of pharmacologic and somatic management for depressive disorders based on severity, subtype (psychotic, atypical), comorbidities (bipolarity), and residual symptoms.

Items

A patient reports a 7-month history of uncontrollable apprehension regarding their job security, children's safety, and household chores, accompanied by chronic fatigue and neck muscle tightness.
A patient describes multiple discrete surges of overwhelming terror that peak within minutes, occurring without any clear trigger, leading to a persistent fear of experiencing another cardiac-like event.
A patient presents with vivid, distressing nightmares and hypervigilance occurring for the past 18 days after witnessing an armed robbery.
A patient actively avoids attending crowded concerts and using subway trains, expressing intense fear that they would not be able to leave quickly if they were to experience a sudden panic attack.

Matches

Show answer & explanation

Answer

The correct pairings align the >6-month multi-domain worry with Generalized Anxiety Disorder, unexpected attacks with Panic Disorder, <1-month trauma symptoms with Acute Stress Disorder, and avoidance of escape-restricted situations with Agoraphobia.
Each diagnosis in the DSM-5 for anxiety and trauma-related disorders has specific duration and criteria thresholds. GAD requires >6 months of worry; Panic Disorder requires unexpected attacks with anticipatory anxiety; Acute Stress Disorder requires trauma symptoms lasting <1 month; and Agoraphobia requires fear of situations where escape is difficult.

Step-by-Step Solution

1
Analyze the duration and focus of the first patient's anxiety.
The anxiety is generalized across multiple domains and lasts >6 months (7 months).
Duration and symptom breadth are key discriminators between transient stress and Generalized Anxiety Disorder.
2
Evaluate the nature of the second patient's anxiety episodes.
The episodes are unprovoked, peak rapidly, and cause anticipatory anxiety.
Spontaneous, recurrent panic attacks distinguish Panic Disorder from phobias where attacks are exclusively cued.
3
Assess the timeline of the third patient's trauma symptoms.
Symptoms began after a trauma and have lasted for exactly 18 days.
The less-than-one-month timeframe differentiates Acute Stress Disorder from Post-Traumatic Stress Disorder.
4
Identify the core fear for the fourth patient.
The fear centers on an inability to escape crowded or enclosed public spaces if incapacitating symptoms occur.
This specific fear of entrapment characterizes Agoraphobia rather than Social Anxiety Disorder, which involves fear of scrutiny.

Matches

Show answer & explanation

Answer

The correct matches align the psychotic/food-refusing patient with ECT, the bipolar depression patient with quetiapine, the uncomplicated MDD patient with an SSRI, and the seasonal pattern patient with bright light therapy.
Each treatment is matched to its classic indication: ECT for rapid response in psychotic or life-threatening depression; quetiapine for bipolar depression to avoid SSRI-induced mania; SSRIs for standard major depression; and light therapy for seasonal pattern.

Step-by-Step Solution

1
Analyze the 75-year-old man's presentation.
Severe depression with psychotic features and food refusal.
Requires the most rapid and effective intervention available, which is ECT.
2
Analyze the 24-year-old woman's presentation.
Depression with a history of mania (elevated mood, decreased sleep, grandiosity).
Indicates bipolar depression, requiring a medication with mood-stabilizing properties (like quetiapine) while avoiding SSRI monotherapy.
3
Analyze the 32-year-old man's presentation.
Uncomplicated, first-episode moderate major depressive disorder.
Warrants standard first-line pharmacotherapy with an SSRI.
4
Analyze the 45-year-old woman's presentation.
Depressive episodes strictly tied to fall and winter months.
Meets criteria for seasonal pattern, making bright light therapy a primary indication.

Question 726Question →

Match each clinical scenario describing a patient with a bipolar spectrum disorder to the most appropriate next step in pharmacological management.

Click a left item, then click its matching right item

Items

A 24-year-old woman presents with acute bipolar depression. She has a documented history of Stevens-Johnson syndrome following a trial of an unknown antiepileptic drug during childhood.
A 28-year-old woman at 9 weeks gestation is admitted for acute, severe mania with psychotic features, marked agitation, and total lack of sleep.
A 60-year-old man requires pharmacological intervention for an acute manic episode. He has a history of decompensated cirrhosis due to chronic alcohol use, but his baseline renal function is entirely normal.
A 45-year-old man requires initiation of maintenance pharmacotherapy for bipolar I disorder. He has chronic kidney disease stage 4 (eGFR 25 mL/min/1.73 m2) secondary to hypertensive nephrosclerosis.

Matches

Show answer & explanation

Answer

Match the scenarios based on absolute contraindications: use lurasidone for the patient with prior Stevens-Johnson syndrome, haloperidol for the pregnant patient in the first trimester, lithium for the patient with severe cirrhosis, and valproate for the patient with severe chronic kidney disease.
Each clinical scenario involves a specific contraindication that eliminates a commonly used first-line bipolar medication, necessitating the selection of an alternative agent with a safe pharmacokinetic or adverse effect profile matched to that patient's systemic comorbidity.

Step-by-Step Solution

1
Analyze the specific phase of bipolar disorder for each patient
Identified presentations of acute depression, acute mania, and the need for maintenance therapy.
Different phases dictate whether an antidepressant (like lurasidone), antimanic (like haloperidol), or standard mood stabilizer is indicated.
2
Evaluate the comorbid medical conditions and medication history
Identified prior Stevens-Johnson syndrome, first-trimester pregnancy, decompensated cirrhosis, and severe chronic kidney disease.
Medical comorbidities represent the primary driver for eliminating standard therapies that might otherwise be considered first-line.
3
Eliminate strictly contraindicated medications for each patient
Avoid lamotrigine in the patient with prior SJS. Avoid valproate, carbamazepine, and lithium in the pregnant patient. Avoid valproate in the cirrhotic patient. Avoid lithium in the chronic kidney disease patient.
Failure to recognize these contraindications can result in catastrophic adverse effects such as hepatotoxicity, nephrotoxicity, severe cutaneous reactions, and teratogenicity.
4
Select the optimal remaining pharmacological agent
Lurasidone (SJS patient), haloperidol (pregnant patient), lithium (cirrhosis patient), and valproate (CKD patient) are properly selected.
These specific agents effectively treat the corresponding mood phase while bypassing the patients' specific metabolic vulnerabilities and contraindications.

Key Concept

Pharmacotherapy selection in bipolar disorder requires careful consideration of the phase of illness and the patient's medical comorbidities, particularly baseline renal function, hepatic function, pregnancy status, and history of severe adverse drug reactions.

Items

Fluctuating cognition, early prominent visual hallucinations, and spontaneous parkinsonism
Stepwise cognitive decline, focal neurological deficits, and evidence of cerebrovascular disease
Early personality changes, significant behavioral disinhibition, and prominent apathy
Progressive cognitive impairment, broad-based gait apraxia, and urinary incontinence

Matches

Show answer & explanation

Answer

The correct pairings match each classic symptom constellation to its distinct etiology: visual hallucinations and parkinsonism indicate Dementia with Lewy bodies; stepwise decline with focal deficits points to Vascular dementia; early personality changes and disinhibition suggest Frontotemporal dementia; and the triad of gait apraxia, urinary incontinence, and dementia characterizes Normal pressure hydrocephalus.
Each neurocognitive disorder has a distinct classic presentation: Dementia with Lewy bodies presents with visual hallucinations and parkinsonism; Vascular dementia presents with stepwise decline and focal deficits; Frontotemporal dementia presents with early personality changes; and Normal pressure hydrocephalus presents with the triad of gait impairment, incontinence, and dementia.

Step-by-Step Solution

1
Analyze the first clinical presentation featuring fluctuating cognition, hallucinations, and parkinsonism.
Identified as Dementia with Lewy bodies.
These are the hallmark core clinical criteria for diagnosing Dementia with Lewy bodies.
2
Evaluate the second presentation featuring stepwise decline and focal deficits.
Identified as Vascular dementia.
A stepwise deterioration with cerebrovascular disease evidence strongly points to a vascular etiology.
3
Review the third presentation highlighting early personality changes and disinhibition.
Identified as Frontotemporal dementia.
The behavioral variant of Frontotemporal dementia is characterized by early behavioral shifts rather than early memory loss.
4
Assess the fourth presentation with gait apraxia, incontinence, and cognitive impairment.
Identified as Normal pressure hydrocephalus.
This is the classic clinical triad ('wobbly, wacky, wet') diagnostic of Normal pressure hydrocephalus.

Click a left item, then click its matching right item

Items

A patient in their late twenties actively avoids driving over bridges and flying in airplanes for 8 months solely because they fear the structures will collapse or the vehicle will crash; they do not fear having a panic attack or being trapped.
An individual describes a 5-week history of intrusive memories, emotional numbing, avoidance of driving, and exaggerated startle response following a severe motor vehicle collision.
A middle-aged executive demands that subordinates strictly follow exact rigid schedules and insists on meticulously organizing the shared workspace, believing this method is the only correct way, which causes severe interpersonal conflict.
A university student experiences pronounced anxiety, insomnia, and difficulty concentrating beginning 1 month after a non-life-threatening romantic breakup; these symptoms cause significant distress but do not meet criteria for another mental disorder.
A young professional declines all invitations to networking events and parties for the past 2 years due to an intense, persistent worry that colleagues will perceive them as awkward or incompetent.

Matches

Show answer & explanation

Answer

The correct matches require applying diagnostic thresholds: the first history is Specific Phobia, the second is Post-Traumatic Stress Disorder, the third is Obsessive-Compulsive Personality Disorder, the fourth is Adjustment Disorder, and the fifth is Social Anxiety Disorder.
Correctly matching these diagnoses requires a nuanced application of exact DSM-5 criteria: identifying the specific cognitive driver of avoidance (fear of harm in Specific Phobia vs. fear of negative evaluation in Social Anxiety Disorder), distinguishing conditions based on exact duration thresholds (PTSD requires symptoms > 1 month), separating ego-syntonic personality traits (OCPD) from ego-dystonic clinical syndromes (OCD), and recognizing that non-life-threatening stressors causing functional impairment warrant an Adjustment Disorder diagnosis.

Step-by-Step Solution

1
Analyze the first clinical history regarding avoidance of bridges and planes.
The avoidance is driven by a fear of structural collapse or crashing (direct harm), pointing to a situational phobia.
Distinguishing the core cognitive fear is essential; fear of harm from the object/situation defines Specific Phobia, unlike fear of panic which indicates Agoraphobia.
2
Evaluate the timeline of symptoms in the second history involving a motor vehicle collision.
Symptoms of intrusion, avoidance, and hyperarousal have lasted for 5 weeks.
The 1-month duration threshold is the critical differentiator between Acute Stress Disorder (< 1 month) and Post-Traumatic Stress Disorder (> 1 month).
3
Examine the third history focusing on rigidity, perfectionism, and control in the workplace.
The individual's behavior is ego-syntonic (they believe their way is the only correct way) and lacks true repetitive obsessions or compulsions.
Ego-syntonic perfectionism without true obsessions or compulsions is the hallmark of Obsessive-Compulsive Personality Disorder, differentiating it from OCD.
4
Assess the nature of the stressor in the fourth history concerning the university student.
Significant emotional distress and impairment developed within 3 months of a non-life-threatening stressor (a breakup).
Non-Criterion A stressors that cause significant impairment but do not meet criteria for another specific psychiatric disorder are diagnosed as Adjustment Disorder.
5
Identify the primary fear driving avoidance in the fifth history about the young professional.
The avoidance of social and networking events is driven by a persistent fear of negative evaluation and being perceived as awkward.
Fear of negative evaluation or scrutiny by others is the defining characteristic of Social Anxiety Disorder.

Key Concept

Differentiating anxiety, trauma-related, and obsessive-compulsive related disorders requires strict adherence to DSM-5 criteria regarding symptom duration (e.g., ASD vs. PTSD), the nature of the inciting event (life-threatening vs. non-life-threatening), the core cognitive fear driving avoidance (e.g., negative evaluation vs. inability to escape vs. specific harm), and assessing whether symptoms are ego-syntonic or ego-dystonic.

Match each clinical presentation of a breast disorder with its most likely corresponding histopathologic finding on biopsy.

Click a left item, then click its matching right item

Items

A 24-year-old woman with a 2-cm mobile, firm, well-circumscribed breast mass; ultrasound demonstrates a homogeneous, solid, hypoechoic oval lesion.
A 48-year-old woman with bilateral, diffuse, tender breast nodularity that fluctuates in severity with her menstrual cycle.
A 36-year-old woman with a firm, localized breast mass and mild skin retraction, developing three months after a motor vehicle collision.
A 31-year-old woman presenting with spontaneous, unilateral bloody nipple discharge without any palpable breast mass or skin changes.

Matches

Show answer & explanation

Answer

The young woman with a mobile mass matches with stromal proliferation (fibroadenoma); the woman with cyclic nodularity matches with cysts and apocrine metaplasia (fibrocystic changes); the trauma patient matches with anucleated adipocytes and macrophages (fat necrosis); and the patient with bloody discharge matches with fibrovascular cores (intraductal papilloma).
Each clinical scenario correlates precisely with a distinct benign breast pathology's characteristic histopathological appearance. Fibroadenomas feature slit-like spaces; fibrocystic changes feature apocrine metaplasia; fat necrosis features lipid-laden macrophages; and intraductal papillomas feature arborizing fibrovascular cores.

Step-by-Step Solution

1
Analyze the presentation of the 24-year-old with a mobile, well-circumscribed mass.
Identified as a fibroadenoma.
Mobile, well-circumscribed, solid hypoechoic masses in young women are classic for fibroadenomas, which are characterized histologically by stromal and epithelial proliferation with slit-like spaces.
2
Analyze the presentation of the 48-year-old with cyclic, bilateral nodularity.
Identified as fibrocystic breast changes.
Cyclic breast pain and nodularity in premenopausal women relate to hormonal changes causing cysts, fibrosis, and hallmark apocrine metaplasia.
3
Analyze the presentation of the 36-year-old with a firm mass and skin retraction after trauma.
Identified as fat necrosis.
Blunt trauma to the breast causes adipocyte necrosis, leading to a localized inflammatory response with lipid-laden macrophages, giant cells, and subsequent fibrosis that can mimic malignancy clinically.
4
Analyze the presentation of the 31-year-old with unilateral bloody nipple discharge.
Identified as an intraductal papilloma.
Bloody or serosanguineous nipple discharge without a palpable mass is the hallmark of an intraductal papilloma, characterized by fibrovascular cores proliferating in a dilated duct.

A 21-year-old nulliparous woman presents with a 2-cm, rubbery, highly mobile, non-tender mass in the upper outer quadrant of her left breast.
A 41-year-old woman reports spontaneous, unilateral, bloody nipple discharge. Physical examination reveals no palpable breast masses or axillary lymphadenopathy.
A 49-year-old perimenopausal woman presents with a soft retroareolar mass, mild nipple inversion, and a thick, pasty, greenish-white nipple discharge.
A 36-year-old woman complains of bilateral, diffuse, cord-like breast thickening and pain that begins a week before her period and resolves after menstruation.

Matches

Show answer & explanation

Answer

The presentations map directly to hallmark benign conditions: the young woman with a mobile mass has a fibroadenoma, the bloody discharge without a mass is an intraductal papilloma, the green discharge with a retroareolar mass is mammary duct ectasia, and the cyclic premenstrual pain represents fibrocystic changes.
Each diagnosis represents a distinct benign breast condition with classic clinical features. Fibroadenomas present as mobile, well-circumscribed masses in young women. Intraductal papillomas present with bloody nipple discharge but no mass. Mammary duct ectasia causes thick, colored discharge and retroareolar masses due to ductal inflammation. Fibrocystic changes cause diffuse, cyclic breast pain and nodularity linked to the menstrual cycle.

Step-by-Step Solution

1
Evaluate the 21-year-old patient's symptoms.
Identify a solitary, mobile, rubbery mass in a young female, which matches Fibroadenoma.
Fibroadenoma is the most common benign breast tumor in women under 30 and classically presents with these physical examination features.
2
Evaluate the 41-year-old patient's symptoms.
Identify unilateral, bloody discharge without a palpable mass, which matches Intraductal papilloma.
A solitary intraductal papilloma is a benign tumor of the lactiferous ducts and is the leading cause of bloody nipple discharge.
3
Evaluate the 49-year-old patient's symptoms.
Identify a retroareolar mass, nipple inversion, and greenish discharge, which matches Mammary duct ectasia.
Duct ectasia involves chronic inflammation and dilation of the major subareolar ducts, leading to thick colored discharge and sometimes mimicking malignancy (nipple inversion).
4
Evaluate the 36-year-old patient's symptoms.
Identify cyclic, bilateral pain and diffuse nodularity, which matches Fibrocystic changes.
Fibrocystic changes are hormonally mediated, causing diffuse breast lumpiness and pain that worsens before menses and improves afterward.

Vignette 1 matches Borderline Personality Disorder; Vignette 2 matches Paranoid Personality Disorder; Vignette 3 matches Obsessive-Compulsive Personality Disorder; Vignette 4 matches Schizotypal Personality Disorder; Vignette 5 matches Schizoid Personality Disorder.
The correct pairings require identifying the core psychodynamic defense mechanisms and pervasive behavioral patterns characteristic of each personality disorder as they manifest in stressful medical settings. Borderline is marked by splitting and abandonment fears; Paranoid by pervasive distrust; OCPD by ego-syntonic rigidity and control; Schizotypal by magical thinking and paranoid social anxiety; and Schizoid by profound interpersonal detachment and flattened affect.

Step-by-Step Solution

1
Evaluate the 34-year-old woman with DKA.
Identify splitting behavior and acute fear of abandonment.
These defense mechanisms are the diagnostic hallmarks of Borderline Personality Disorder.
2
Evaluate the 52-year-old man with abdominal pain.
Identify pervasive suspicion and interpretation of benign events as malicious plots.
This non-delusional paranoia is the core defining feature of Paranoid Personality Disorder.
3
Evaluate the 40-year-old man scheduled for hernia repair.
Identify extreme rigidity, perfectionism, and an intense need for control.
These ego-syntonic traits define Obsessive-Compulsive Personality Disorder.
4
Evaluate the 29-year-old woman with asthma.
Identify magical thinking, odd appearance, and paranoid social anxiety.
These eccentricities and cognitive distortions point directly to Schizotypal Personality Disorder.
5
Evaluate the 60-year-old man with pneumonia.
Identify profound social detachment, restricted affect, and indifference.
This genuine lack of desire for relationships and emotional flattening is classic for Schizoid Personality Disorder.

A medical student is reviewing the pharmacological management of bipolar disorder. Match each medication to its most appropriate baseline screening and monitoring requirement prior to initiation.

Click a left item, then click its matching right item

Items

Lithium
Valproate
Carbamazepine
Ziprasidone

Matches

Show answer & explanation

Answer

Lithium matches with TSH/renal function; Valproate matches with LFTs/platelets; Carbamazepine matches with CBC/HLA-B*1502; Ziprasidone matches with ECG/electrolytes.
The correct matches directly correspond to the distinct, high-yield toxicity profiles of each medication used in bipolar disorder management.

Step-by-Step Solution

1
Identify the clearance mechanism and major organ toxicities for Lithium.
Lithium is renally excreted and strongly affects thyroid tissue. Therefore, TSH, BUN, and creatinine are required.
To establish a baseline before exposing the kidneys and thyroid to potential lithium-induced toxicity.
2
Identify the major black box warnings for Valproate.
Valproate is known for severe hepatotoxicity and thrombocytopenia, matching it directly to LFTs and platelet count.
To ensure normal hepatic function and hematologic status prior to initiation.
3
Recall the hematologic and dermatologic risks of Carbamazepine.
Carbamazepine can cause agranulocytosis and Stevens-Johnson syndrome (linked to the HLA-B*1502 allele), requiring a CBC and genetic screening.
To prevent severe hematologic dyscrasias and life-threatening dermatologic reactions.
4
Recognize the specific cardiac risk associated with Ziprasidone.

Show answer & explanation

Answer

Atypical Ductal Hyperplasia requires excisional biopsy. Phyllodes tumor requires wide local excision with >1cm margins. Inflammatory Breast Cancer requires neoadjuvant chemotherapy. Paget disease of the breast requires evaluation for an underlying malignancy. Classic Lobular Carcinoma In Situ is managed with high-risk surveillance and chemoprevention.
Each specific breast pathology has a uniquely tailored management pathway based on its biological behavior. ADH is high-risk for concurrent malignancy and needs excision. Phyllodes tumors recur locally and spread hematogenously, needing wide margins but not axillary staging. IBC is locally advanced and requires upfront systemic therapy. Paget disease is an indicator of deeper malignancy. Classic LCIS is a bilateral risk marker requiring surveillance rather than localized excision.

Step-by-Step Solution

1
Evaluate the patient with atypical ductal hyperplasia (ADH) on core biopsy.
Match ADH with the need for surgical excisional biopsy.
Core needle biopsy samples only a small portion of the lesion; ADH has a high rate of upstaging to DCIS or invasive carcinoma, so the entire abnormality must be excised for full histologic evaluation.
2
Evaluate the patient with a rapidly enlarging fibroepithelial lesion showing stromal atypia.
Identify as a phyllodes tumor and match with wide local excision (>1 cm margins).
Phyllodes tumors have a high local recurrence rate if excised with positive margins. They spread via hematogenous routes, making axillary staging unnecessary unless nodes are clinically palpable.
3
Evaluate the patient with dermal lymphatic invasion by tumor cells and skin dimpling.
Identify as inflammatory breast cancer (IBC) and match with neoadjuvant chemotherapy.
IBC is an aggressive, locally advanced cancer. Primary surgery is contraindicated due to a high likelihood of positive margins; therapy must begin with systemic chemotherapy.
4
Evaluate the patient with large clear cells in the nipple epidermis.
Identify as Paget disease of the breast and match with the need for comprehensive imaging.
Paget cells represent intraepidermal spread of malignant cells from deeper within the breast parenchyma; the vast majority of these patients have an underlying underlying DCIS or invasive cancer.
5
Evaluate the patient with classic lobular carcinoma in situ (LCIS) that is concordant with imaging.
Match with high-risk surveillance and endocrine risk-reduction therapy.
Unlike DCIS, classic LCIS is a marker of increased risk for developing cancer in either breast. If concordant with imaging, it does not mandate surgical excision.

Key Concept

Management of high-risk breast lesions and unique breast malignancies requires specific, evidence-based approaches that differ significantly from standard invasive ductal carcinoma.

A 45-year-old executive demands to see the 'chief of medicine', boasts about his unique talents, and dismisses the inconvenience his demands cause the clinic staff.
A 35-year-old night shift guard has no friends by choice, shows flat affect, prefers solitary activities, and states he has no interest in close relationships.

Matches

Show answer & explanation

Answer

The correct matches are: the 24-year-old woman with Avoidant Personality Disorder, the 30-year-old man with Histrionic Personality Disorder, the 45-year-old executive with Narcissistic Personality Disorder, and the 35-year-old guard with Schizoid Personality Disorder.
Each vignette describes the classic, undisputed DSM-5 diagnostic criteria for the respective personality disorders, focusing on their most defining features (social inhibition for avoidant, attention-seeking for histrionic, grandiosity for narcissistic, and detachment for schizoid).

Step-by-Step Solution

1
Analyze the first vignette for core personality traits.
The patient shows social inhibition and fear of criticism despite an underlying desire to be accepted.
This differentiates avoidant traits from those of cluster A disorders where there is no desire for social connection.
2
Analyze the second vignette.
The patient demonstrates attention-seeking, flamboyant, and theatrical behavior.
These are the hallmark criteria for Histrionic personality disorder (Cluster B).
3
Analyze the third vignette.
The patient exhibits grandiosity, entitlement, and a profound lack of empathy for others.
These traits specifically define Narcissistic personality disorder (Cluster B).
4
Analyze the fourth vignette.
The patient shows social detachment by choice and restricted affect.
These represent the core diagnostic criteria for Schizoid personality disorder (Cluster A).

A twenty-five-year-old graduate student relies entirely on her roommate to choose her daily outfits. She feels profound helplessness and fear when briefly left alone.
A thirty-one-year-old fitness instructor uses highly impressionistic speech and theatrical gestures to describe a minor inconvenience, insisting the clinic staff are her 'dearest friends'.

Matches

Show answer & explanation

Answer

The accountant matches Avoidant Personality Disorder. The archivist matches Schizoid Personality Disorder. The graduate student matches Dependent Personality Disorder. The fitness instructor matches Histrionic Personality Disorder.
Each vignette provides the defining DSM-5 criteria for a specific personality disorder. The accountant's fear of criticism points to Avoidant Personality Disorder. The archivist's lack of interest in others indicates Schizoid Personality Disorder. The student's excessive need for support aligns with Dependent Personality Disorder. The instructor's theatricality and attention-seeking indicate Histrionic Personality Disorder.

Step-by-Step Solution

1
Analyze the patients presenting with social withdrawal (the accountant versus the archivist) to determine the underlying motivation.
The accountant avoids socializing due to fear of rejection but desires connection, whereas the archivist genuinely prefers isolation and lacks interest in peers.
Differentiating ego-syntonic isolation (Cluster A) from ego-dystonic isolation (Cluster C) is a critical diagnostic step.
2
Evaluate the patient displaying excessive reliance on others (the graduate student).
The student exhibits an excessive need to be taken care of and an inability to make everyday decisions independently.
This behavioral pattern confirms a diagnosis of Dependent Personality Disorder.
3
Assess the patient with a dramatic, emotional presentation (the fitness instructor).
The instructor displays theatricality, attention-seeking behavior, and rapidly shifting emotions.
These are core diagnostic criteria for Histrionic Personality Disorder.

Key Concept

Distinguishing between personality disorders requires identifying the core motivations behind behaviors, such as differentiating the isolation seen in schizoid versus avoidant personality disorders.

Match each depressive disorder or specifier with its most characteristic clinical presentation.

Click a left item, then click its matching right item

Items

Major depressive disorder with atypical features
Major depressive disorder with melancholic features
Persistent depressive disorder (dysthymia)
Premenstrual dysphoric disorder

Matches

Show answer & explanation

Answer

Major depressive disorder with atypical features matches with mood reactivity, hyperphagia, and hypersomnia. Major depressive disorder with melancholic features matches with pervasive anhedonia, early morning awakening, and weight loss. Persistent depressive disorder matches with chronic depressed mood for at least 2 years. Premenstrual dysphoric disorder matches with symptoms occurring in the luteal phase.
Matching depressive disorders to their classic criteria requires recognizing pathognomonic symptom clusters. Atypical features present with mood reactivity and 'reversed' vegetative symptoms (hyperphagia, hypersomnia). Melancholic features present with profound anhedonia and classic vegetative symptoms (insomnia, weight loss). Persistent depressive disorder is defined by chronicity (at least 2 years). Premenstrual dysphoric disorder is defined by its relation to the luteal phase of the menstrual cycle.

Step-by-Step Solution

1
Evaluate the clinical description for mood reactivity combined with reversed vegetative symptoms (increased sleep and appetite).
Identified as atypical features.
These are the classic DSM-5 diagnostic criteria for the 'with atypical features' specifier of major depressive disorder.
2
Evaluate the clinical description for complete anhedonia, unreactive mood, and classic vegetative symptoms like early morning awakening.
Identified as melancholic features.
These severe symptoms define the melancholic specifier, separating it from typical or atypical presentations.
3
Evaluate the clinical description regarding the chronicity of the depressed mood.
A duration of 2 years or more without a 2-month gap identifies persistent depressive disorder.
The 2-year timeline is the core defining diagnostic criterion for persistent depressive disorder (dysthymia) in adults.
4
Evaluate the clinical description for mood symptoms strictly tied to the menstrual cycle.
Symptoms restricted to the luteal phase identify premenstrual dysphoric disorder.
The cyclic nature of severe mood symptoms correlating with the luteal phase and resolving with menses is the hallmark of this disorder.

Generalized Anxiety Disorder
Panic Disorder
Social Anxiety Disorder
Specific Phobia

Matches

Show answer & explanation

Answer

Generalized Anxiety Disorder matches excessive worry lasting 6 months; Panic Disorder matches recurrent unexpected episodes of intense fear; Social Anxiety Disorder matches fear of negative evaluation; Specific Phobia matches fear of a discrete object or situation.
Each anxiety disorder is defined by its primary focus of fear or anxiety. Generalized Anxiety Disorder involves broad, free-floating worry. Panic disorder is characterized by unexpected panic attacks and the fear of having another one. Social Anxiety Disorder specifically involves the fear of negative evaluation by others. Specific phobia involves fear isolated to a specific trigger.

Step-by-Step Solution

1
Analyze the core features of each clinical presentation provided in the right column.
Identified four distinct core features: chronic worry, unexpected panic attacks, fear of scrutiny, and fear of discrete triggers.
Anxiety disorders are primarily distinguished by the specific target or nature of the patient's fear and the duration of symptoms.
2
Map the distinct core features to their corresponding DSM-5 diagnostic categories.
Chronic worry maps to Generalized Anxiety Disorder, unexpected attacks to Panic Disorder, fear of scrutiny to Social Anxiety Disorder, and discrete triggers to Specific Phobia.
This directly aligns with standard psychiatric diagnostic criteria.

A 60-year-old patient with major depressive disorder who was hospitalized for a myocardial infarction two weeks ago.

Matches

Show answer & explanation

Answer

The correct matches link the patient with diabetic neuropathy to Duloxetine; the patient avoiding sexual dysfunction and weight gain to Bupropion; the patient with insomnia and weight loss to Mirtazapine; and the patient with a recent myocardial infarction to Sertraline.
The correct pairings rely on matching the known side effects and secondary indications of antidepressants with specific patient needs. Duloxetine treats neuropathy; bupropion avoids sexual dysfunction; mirtazapine promotes sleep and appetite; and sertraline is safe post-myocardial infarction.

Step-by-Step Solution

1
Analyze the first patient's comorbidities.
The patient has diabetic peripheral neuropathy in addition to depression.
Identifying comorbid neuropathic pain guides the selection toward an SNRI like duloxetine, which treats both conditions.
2
Analyze the second patient's specific concerns regarding medication side effects.
The patient wants to avoid sexual dysfunction and weight gain.
This rules out most SSRIs and points toward bupropion, an NDRI with a favorable profile regarding sexual function and weight.
3
Analyze the third patient's specific depressive symptoms.
The patient suffers from severe insomnia and significant weight loss.
This points toward mirtazapine, which is known for its sedating and appetite-stimulating side effects.
4
Analyze the fourth patient's recent medical history.
The patient had a myocardial infarction two weeks ago.
This requires a cardiac-safe antidepressant. Sertraline is the SSRI of choice for patients with ischemic heart disease.

Matches

Show answer & explanation

Answer

The scenarios match distinct procedural complications based on diagnostic dye tests, timing of symptom onset, and pathophysiologic mechanisms of injury.
Each clinical scenario requires synthesizing postoperative timing, vital signs, and diagnostic test results to identify the specific anatomical or physiologic complication of common gynecologic surgeries.

Step-by-Step Solution

1
Analyze the dye test results in the first scenario.
Intravenous indigo carmine stains the tampon, but intravesical methylene blue does not.
This confirms the fluid leakage is originating from the ureter rather than the bladder, establishing the diagnosis of a ureterovaginal fistula.
2
Evaluate the triad of symptoms in the second scenario.
The patient exhibits ascites, ileus, and rising creatinine on postoperative day 3.
This indicates reverse autodialysis of intraperitoneal urine, pointing to an unrecognized bladder dome perforation causing chemical peritonitis.
3
Correlate the timing of bleeding in the third scenario.
Severe bleeding occurs exactly 12 days after a loop electrosurgical excision procedure.
This corresponds directly to the normal timeline of cervical eschar sloughing, a known cause of delayed secondary hemorrhage.
4
Identify the cause of acute neurologic and respiratory symptoms in the fourth scenario.
Immediate postoperative seizures and pulmonary edema follow an operative hysteroscopy.
This indicates massive intravascular absorption of hypotonic distension media, leading to acute hypervolemic hyponatremia (hysteroscopic syndrome).

A 45-year-old man diagnosed with invasive ductal carcinoma of the breast whose father recently passed away from pancreatic adenocarcinoma.
A 35-year-old woman with triple-negative breast cancer whose mother and maternal aunt both died of high-grade serous ovarian carcinoma.

Matches

Show answer & explanation

Answer

The patient with the osteosarcoma and adrenocortical carcinoma family history matches the TP53 mutation (Li-Fraumeni syndrome). The patient with macrocephaly and follicular thyroid carcinoma matches the PTEN mutation (Cowden syndrome). The male patient with a family history of pancreatic cancer matches the BRCA2 mutation. The patient with triple-negative breast cancer and a strong family history of ovarian carcinoma matches the BRCA1 mutation.
Each genetic mutation produces a distinct familial cancer syndrome with characteristic phenotypic features. TP53 mutations cause Li-Fraumeni syndrome (sarcomas, brain tumors, adrenocortical carcinoma). PTEN mutations cause Cowden syndrome (macrocephaly, follicular thyroid cancer, endometrial cancer). BRCA2 is highly associated with male breast cancer and pancreatic cancer. BRCA1 strongly predisposes to triple-negative breast cancer and early-onset ovarian carcinoma.

Step-by-Step Solution

1
Evaluate the first patient's family history of osteosarcoma and adrenocortical carcinoma.
Identified as classic malignancies associated with Li-Fraumeni syndrome.
To determine the genetic syndrome caused by TP53 mutations.
2
Analyze the second patient's associated findings of macrocephaly and follicular thyroid carcinoma.
Recognized as distinctive phenotypic features of Cowden syndrome.
To link these specific clinical traits to a PTEN mutation.
3
Assess the third patient's male sex and family history of pancreatic cancer.
Correlated specifically with BRCA2 mutations.
BRCA2 has a notably stronger association with male breast cancer and pancreatic cancer compared to other common genetic predispositions.
4
Examine the fourth patient's triple-negative breast cancer and strong ovarian cancer family history.
Linked to a BRCA1 mutation.
BRCA1 is classically associated with triple-negative breast cancers and a high risk of high-grade serous ovarian cancer at a young age.
