Items

A 23-year-old presents with multiple exquisitely tender, deep vulvar ulcerations featuring a purulent base, accompanied by fluctuant inguinal lymph nodes. Microscopic evaluation of the exudate shows Gram-negative coccobacilli arranged in parallel chains.
A 29-year-old is evaluated for a slowly expanding, painless, beefy-red vulvar ulceration that is highly vascular and bleeds easily. Tissue microscopy demonstrates bipolar-staining bacterial inclusions enclosed within large mononuclear macrophages.
A 26-year-old returns to the clinic with persistent mucopurulent cervicitis and intermenstrual bleeding, having recently failed empiric single-dose and seven-day antibiotic courses. Molecular testing isolates a fastidious, cell-wall-lacking pathogen known for widespread macrolide resistance.
A 21-year-old presents with a unilateral, painful conglomerate of enlarged inguinal lymph nodes separated by a groove. She notes a transient, painless genital papule that resolved without intervention several weeks ago.

Matches

Show answer & explanation

Answer

The correct pairings appropriately match the painful ulcers of Chancroid to single-dose therapy, the beefy-red painless ulcers of Granuloma inguinale to prolonged >3-week therapy, the macrolide-resistant Mycoplasma genitalium cervicitis to sequential two-stage therapy, and the buboes of Lymphogranuloma venereum to a 21-day tetracycline course.
The correct pairings accurately reflect current therapeutic guidelines for specific, highly tested genital infections. Chancroid is highly susceptible and requires only single-dose therapy. Granuloma inguinale necessitates prolonged therapy until complete tissue healing is achieved. Mycoplasma genitalium cervicitis, due to its concerning resistance patterns, strictly requires a resistance-guided or two-stage approach utilizing a tetracycline followed by a fluoroquinolone. Lymphogranuloma venereum requires a specific 21-day tetracycline course along with possible mechanical drainage of suppurative lymph nodes.

Step-by-Step Solution

1
Differentiate the etiology of the genital lesions based on pain, morphology, and lymphadenopathy.
Painful ulcers with fluctuant nodes indicate Chancroid; painless beefy-red vascular ulcers indicate Granuloma inguinale; transient painless ulcers followed by painful coalesced buboes indicate Lymphogranuloma venereum.
Pain is the primary differentiating clinical feature for genital ulcers, significantly narrowing the differential diagnosis before incorporating microscopic findings.
2
Correlate specific microscopic findings and clinical history with the causative pathogens.
Parallel bacterial chains identify Haemophilus ducreyi; macrophage inclusions identify Klebsiella granulomatis; persistent cervicitis failing standard therapy identifies Mycoplasma genitalium.
Precise pathogen identification is required because each of these organisms has distinct pharmacokinetic requirements for eradication.
3
Assign the guideline-concordant antimicrobial regimen to each identified organism.
Chancroid receives single-dose therapy; Granuloma inguinale receives >3 weeks of therapy; Mycoplasma genitalium receives sequential doxycycline then moxifloxacin; LGV receives exactly 21 days of doxycycline.
Matching the exact temporal and sequential pharmacological requirements ensures definitive tissue healing and mitigates antimicrobial resistance.

Key Concept

Distinctive clinical presentations, microscopic findings, and precise antimicrobial regimens for classic and emerging lower genital tract infections.

A 28-year-old woman who is 3 weeks postpartum, exclusively breastfeeding, and prefers to take a daily pill.

Matches

Show answer & explanation

Answer

Match the 35-year-old smoker with the Copper intrauterine device, the 24-year-old with heavy bleeding with the Levonorgestrel-releasing intrauterine device, the 20-year-old with acne with the Combined oral contraceptive pill, and the 28-year-old postpartum woman with the Progestin-only pill.
Each correct match safely aligns a specific clinical profile with the safest and most beneficial contraceptive mechanism, strictly adhering to the World Health Organization Medical Eligibility Criteria.

Step-by-Step Solution

1
Analyze the profile of the 35-year-old smoker.
Identify that estrogen is contraindicated and select the Copper intrauterine device.
Combined hormonal contraceptives are absolutely contraindicated in women age 35 and older who smoke due to a high risk of cardiovascular events; she also requested a hormone-free method.
2
Evaluate the 24-year-old with heavy menstrual bleeding and dysmenorrhea.
Select the Levonorgestrel-releasing intrauterine device.
This device releases local progestin, which atrophies the endometrium, significantly reducing menstrual blood loss and pain.
3
Assess the 20-year-old with acne and irregular cycles.
Choose the Combined oral contraceptive pill.
The estrogen and progestin combination provides predictable withdrawal bleeding and decreases hyperandrogenism, effectively treating her acne.
4
Consider the 28-year-old who is 3 weeks postpartum and breastfeeding.
Select the Progestin-only pill.
Estrogen is contraindicated within the first month postpartum due to the hypercoagulable state of pregnancy; a progestin-only method meets her preference for a daily pill safely.

Key Concept

Applying the WHO Medical Eligibility Criteria for contraceptive use based on patient comorbidities and reproductive goals.

Items

Endodermal sinus (yolk sac) tumor
Granulosa cell tumor
Dysgerminoma
Serous cystadenocarcinoma

Matches

Show answer & explanation

Answer

Endodermal sinus (yolk sac) tumor matches with Alpha-fetoprotein (AFP); Granulosa cell tumor matches with Inhibin; Dysgerminoma matches with Lactate dehydrogenase (LDH); Serous cystadenocarcinoma matches with Cancer antigen 125 (CA-125).
Each gynecologic neoplasm is associated with a specific, characteristic tumor marker used for diagnosis and monitoring of disease. Endodermal sinus tumors produce AFP, granulosa cell tumors produce inhibin, dysgerminomas frequently present with elevated LDH, and epithelial tumors such as serous cystadenocarcinoma are monitored with CA-125.

Step-by-Step Solution

1
Identify the tumor marker for endodermal sinus (yolk sac) tumor.
Alpha-fetoprotein (AFP)
Yolk sac tumors are malignant germ cell tumors that characteristically secrete high levels of AFP.
2
Identify the tumor marker for granulosa cell tumor.
Inhibin
Granulosa cell tumors are sex cord-stromal tumors that typically secrete estrogen and inhibin, making inhibin a useful marker for diagnosis and monitoring.
3
Identify the tumor marker for dysgerminoma.
Lactate dehydrogenase (LDH)
Dysgerminomas are the most common malignant ovarian germ cell tumors and are typically associated with elevated LDH levels.
4
Identify the tumor marker for serous cystadenocarcinoma.
Cancer antigen 125 (CA-125)
Serous cystadenocarcinoma is the most common malignant epithelial ovarian cancer, which is characteristically monitored using serum CA-125 levels.

Match each common gynecologic infection with its characteristic clinical presentation and microscopic findings.

Click a left item, then click its matching right item

Items

Bacterial vaginosis
Trichomoniasis
Vulvovaginal candidiasis
Gonococcal cervicitis

Matches

Show answer & explanation

Answer

Bacterial vaginosis pairs with thin grayish discharge and clue cells. Trichomoniasis pairs with frothy yellow-green discharge and motile organisms. Vulvovaginal candidiasis pairs with thick white discharge and pseudohyphae. Gonococcal cervicitis pairs with mucopurulent exudate and gram-negative diplococci.
Each gynecologic infection has distinct hallmark findings. Bacterial vaginosis is identified by clue cells and a thin, homogeneous discharge. Trichomoniasis features motile, flagellated organisms in a frothy discharge, sometimes accompanied by a 'strawberry cervix' (punctate hemorrhages). Vulvovaginal candidiasis is distinguished by pseudohyphae on KOH prep, normal vaginal pH, and thick, cottage cheese-like discharge. Finally, gonococcal cervicitis is a classic cause of mucopurulent discharge showing gram-negative intracellular diplococci.

Step-by-Step Solution

1
Analyze the discharge characteristics and microscopy findings in the provided descriptions.
Identified key diagnostic phrases: clue cells, motile flagellated organisms, pseudohyphae, and intracellular diplococci.
These microscopic findings are pathognomonic for specific lower reproductive tract infections.
2
Correlate each pathognomonic finding with the correct causative organism.
Matched the specific descriptions to Bacterial vaginosis, Trichomoniasis, Vulvovaginal candidiasis, and Gonococcal cervicitis, respectively.
Correct identification of the pathogen determines the appropriate antimicrobial therapy.

Key Concept

Accurate diagnosis of common vaginitis and cervicitis requires correlating clinical discharge appearance with specific point-of-care testing such as vaginal pH, wet mount, and KOH preparation.
Question 705Question →

A family planning clinic is evaluating multiple patients who are seeking reliable, reversible contraception. Each patient has distinct medical comorbidities that impact the safety of various contraceptive methods according to the World Health Organization Medical Eligibility Criteria (WHO MEC). Match each patient's clinical presentation with the single most appropriate contraceptive method.

Items

A 34-year-old woman with poorly controlled hypertension (162/104 mmHg) and severe dysmenorrhea.
A 28-year-old woman with systemic lupus erythematosus and positive antiphospholipid antibodies.
A 22-year-old woman with active Chlamydia trachomatis cervicitis who requests a long-acting contraceptive today.
A 38-year-old woman who smokes a pack of cigarettes daily and specifically requests a daily, orally administered contraceptive.

Matches

Show answer & explanation

Answer

The hypertensive patient with dysmenorrhea should receive the Levonorgestrel-releasing intrauterine device. The patient with SLE and antiphospholipid antibodies should receive the Copper intrauterine device. The patient with active cervicitis should receive the Subdermal etonogestrel implant. The 38-year-old smoker desiring an oral method should receive the Progestin-only pill.
Each patient presentation highlights a specific WHO MEC Category 4 (absolute) or Category 3 (relative) contraindication. Estrogen is contraindicated in severe hypertension and in smokers over age 35. All hormones are contraindicated in patients with positive antiphospholipid antibodies. IUD placement is contraindicated during active cervical infections.

Step-by-Step Solution

1
Evaluate the patient with severe hypertension and dysmenorrhea.
Exclude estrogen-containing methods; select a method that treats dysmenorrhea.
Estrogen exacerbates cardiovascular risk in severe hypertension. The levonorgestrel IUD provides excellent contraception while treating heavy or painful menses.
2
Evaluate the patient with SLE and positive antiphospholipid antibodies.
Exclude all hormonal (estrogen and progestin) methods.
Positive antiphospholipid antibodies confer an unacceptably high risk of thrombosis with hormonal methods. The copper IUD is the safest highly effective, hormone-free alternative.
3
Evaluate the patient with active cervicitis seeking a long-acting method.
Exclude all intrauterine devices; select the subdermal implant.
Inserting an IUD through an infected cervix can seed bacteria into the upper genital tract, causing pelvic inflammatory disease. The implant provides immediate, long-acting protection without this risk.
4
Evaluate the 38-year-old smoker requesting a daily pill.
Exclude combined oral contraceptives; select the progestin-only pill.
Age 35 or older combined with heavy smoking creates an unacceptable risk for myocardial infarction and stroke if given estrogen. The progestin-only pill meets her preference for a daily oral formulation safely.

Match each gynecologic malignancy with its most characteristic risk factor or pathogenetic association.

Click a left item, then click its matching right item

Items

Type I Endometrial Adenocarcinoma
Type II Endometrial (Serous) Carcinoma
Cervical Squamous Cell Carcinoma
Ovarian Clear Cell Carcinoma
Vaginal Clear Cell Adenocarcinoma

Matches

Show answer & explanation

Answer

Type I Endometrial Adenocarcinoma matches with chronic unopposed estrogen; Type II Endometrial Carcinoma matches with p53 mutations; Cervical Squamous Cell Carcinoma matches with high-risk HPV and tobacco use; Ovarian Clear Cell Carcinoma matches with endometriosis; Vaginal Clear Cell Adenocarcinoma matches with in utero DES exposure.
Each gynecologic malignancy arises from a specific pathophysiologic mechanism. Type I endometrial cancer depends on estrogen stimulation, while Type II is associated with p53 mutations and atrophy. Cervical cancer requires persistent HPV infection, exacerbated by smoking. Ovarian clear cell cancer is linked to the chronic inflammation of endometriosis, and vaginal clear cell adenocarcinoma is a historical consequence of in utero DES exposure.

Step-by-Step Solution

1
Analyze the pathogenesis of Type I versus Type II endometrial carcinoma.
Type I is driven by unopposed estrogen, whereas Type II occurs in atrophic endometrium and is associated with p53 mutations.
Distinguishing the two main types of endometrial cancer is essential for accurate risk factor matching.
2
Identify the primary risk factors for cervical and vaginal carcinomas.
Cervical cancer is strongly linked to high-risk HPV and smoking. Vaginal clear cell adenocarcinoma is uniquely associated with in utero DES exposure.
These are classic epidemiological associations in gynecologic oncology that are frequently tested.
3
Determine the association between endometriosis and specific ovarian cancers.
Endometriosis is a known precursor lesion specifically for clear cell and endometrioid carcinomas of the ovary.
Understanding the malignant transformation risk of benign gynecologic conditions guides diagnosis and surveillance.

Key Concept

Gynecologic malignancies have distinct risk factors and pathogenetic pathways that guide screening, prevention, and diagnosis.

Matches

Show answer & explanation

Answer

Match the BRCA1-mutated ovarian cancer to PARP inhibitor maintenance, the dMMR endometrial cancer to PD-1 inhibitor monotherapy, the platinum-resistant FR-alpha positive ovarian cancer to an antibody-drug conjugate, and the PD-L1 positive metastatic cervical cancer to combination chemo-immunotherapy plus anti-VEGF.
Each specific gynecologic malignancy scenario relies on a unique biomarker (BRCA, dMMR, FR-alpha, PD-L1) that dictates its corresponding optimal targeted therapy according to the latest standards of care.

Step-by-Step Solution

1
Analyze Patient 1's profile: Stage III high-grade serous ovarian cancer, responsive to platinum, with a BRCA1 mutation.
Identified indication for targeted maintenance therapy exploiting homologous recombination deficiency.
BRCA-mutated ovarian cancers are highly sensitive to PARP inhibitors due to synthetic lethality.
2
Analyze Patient 2's profile: Metastatic endometrial cancer with absent MLH1/PMS2.
Identified mismatch repair deficiency (dMMR).
dMMR tumors predict a strong response to immune checkpoint blockade as monotherapy.
3
Analyze Patient 3's profile: Platinum-resistant ovarian cancer with high folate receptor-alpha expression.
Identified indication for targeted antibody-drug conjugate therapy.
Folate receptor-alpha is directly targeted by mirvetuximab soravtansine in the platinum-resistant setting.
4
Analyze Patient 4's profile: Metastatic cervical cancer with high PD-L1 expression.
Identified indication for systemic combination therapy.
PD-L1 positivity in advanced cervical cancer warrants the addition of a PD-1 inhibitor to standard chemotherapy and anti-VEGF therapy.

Items

A 24-year-old woman with irregular menses, acne, and elevated serum testosterone levels.
A 27-year-old woman with amenorrhea, bilateral milky nipple discharge, and a normal thyroid-stimulating hormone level.
A 32-year-old woman with secondary amenorrhea, vaginal dryness, hot flashes, and an elevated follicle-stimulating hormone level.
A 19-year-old elite distance runner with secondary amenorrhea, a body mass index of 16.5 kg/m², and low luteinizing hormone and follicle-stimulating hormone levels.

Matches

Show answer & explanation

Answer

The presentations match as follows: The hyperandrogenic patient has Polycystic ovary syndrome. The patient with galactorrhea has Hyperprolactinemia. The patient with hypoestrogenic symptoms and high FSH has Primary ovarian insufficiency. The elite runner with low BMI and low FSH/LH has Functional hypothalamic amenorrhea.
Each clinical scenario provides classic, pathognomonic features for a distinct etiology of amenorrhea. Polycystic ovary syndrome is characterized by hyperandrogenism and ovulatory dysfunction. Hyperprolactinemia presents with galactorrhea. Primary ovarian insufficiency presents with hypergonadotropic hypogonadism and menopausal symptoms before age 40. Functional hypothalamic amenorrhea presents with hypogonadotropic hypogonadism in the setting of low energy availability.

Step-by-Step Solution

1
Evaluate the 24-year-old with irregular menses and hyperandrogenism.
Matches with Polycystic ovary syndrome.
These represent the core Rotterdam criteria for diagnosing polycystic ovary syndrome.
2
Evaluate the 27-year-old with amenorrhea and galactorrhea.
Matches with Hyperprolactinemia.
Elevated prolactin inhibits hypothalamic GnRH release, causing amenorrhea, and directly stimulates breast tissue, causing galactorrhea.
3
Evaluate the 32-year-old with hot flashes and high follicle-stimulating hormone (FSH).
Matches with Primary ovarian insufficiency.
Premature depletion of ovarian follicles leads to low estrogen (hot flashes) and a loss of negative feedback, thereby increasing FSH.
4
Evaluate the 19-year-old runner with a low BMI and low gonadotropins.
Matches with Functional hypothalamic amenorrhea.
An energy deficit from intense exercise and low body weight suppresses hypothalamic GnRH pulsatility, leading to low FSH and LH.

A patient exhibits persistent fever spikes and tachycardia on postpartum day 6, despite 72 hours of appropriate intravenous gentamicin and clindamycin therapy, with a benign abdominal examination.
A patient develops fever, worsening lower abdominal pain, and marked erythema, induration, and purulent drainage originating from the margins of her Pfannenstiel incision on postpartum day 5.

Matches

Show answer & explanation

Answer

The presentations map appropriately to their respective localized or systemic diagnoses based on timing and physical examination findings: fundal tenderness indicates endometritis, late unilateral breast erythema indicates mastitis, refractory fever without focal signs indicates septic pelvic thrombophlebitis, and incisional purulence indicates a surgical site infection.
The correct pairings rely on matching the distinct temporal onset and focal physical examination findings to the corresponding postpartum complication. Endometritis presents early with uterine tenderness; mastitis presents later with unilateral breast symptoms; surgical site infections localize to the incision; and septic pelvic thrombophlebitis is a diagnosis of exclusion when fever persists despite broad-spectrum antibiotics.

Step-by-Step Solution

1
Evaluate the timing of the fever relative to the delivery date.
Fevers on days 2-3 often suggest endometritis, days 5-7 suggest a wound infection or septic pelvic thrombophlebitis, and late fevers (weeks 2-4) suggest mastitis.
The temporal onset is a key distinguishing factor in the differential diagnosis of postpartum infections.
2
Identify focal physical examination findings associated with the fever.
Fundal tenderness points to endometritis, unilateral breast erythema points to mastitis, and incisional purulence points to a surgical site infection.
Localizing signs pinpoint the anatomical source of the infection and guide specific management.
3
Assess the patient's response to initial empiric antibiotic therapy.
Refractory fever despite broad-spectrum coverage for endometritis strongly suggests septic pelvic thrombophlebitis or an undrained deep abscess.
Failure of standard therapy requires broadening the differential diagnosis to include complications like venous thrombosis.

Key Concept

The differential diagnosis of postpartum fever relies on recognizing specific temporal patterns and localizing physical examination findings.
Question 710Question →

Match each clinical presentation of an obstetric emergency to the most likely diagnosis.

Click a left item, then click its matching right item

Items

Sudden-onset severe abdominal pain, vaginal bleeding, and frequent late fetal heart rate decelerations at 37 weeks gestation.
Painless, bright red vaginal bleeding without uterine contractions at 36 weeks gestation.
Painless vaginal bleeding and profound fetal bradycardia occurring immediately following artificial rupture of membranes.
Sudden cessation of labor, acute tearing abdominal pain, and loss of fetal station in a patient with a prior cesarean delivery.

Matches

Show answer & explanation

Answer

Sudden-onset severe pain matches with placental abruption; painless bleeding without contractions matches with placenta previa; bleeding and fetal bradycardia immediately after amniotomy matches with vasa previa; and sudden cessation of labor in a scarred uterus matches with uterine rupture.
Each obstetric emergency has a defining clinical signature. Placental abruption is characterized by painful bleeding and fetal distress. Placenta previa is identified by painless bleeding without contractions. Vasa previa involves painless bleeding of fetal origin immediately upon rupture of membranes, causing rapid fetal bradycardia. Uterine rupture is diagnosed by acute tearing pain, cessation of labor, and loss of fetal station in a patient with a prior uterine scar.

Step-by-Step Solution

1
Analyze the presence or absence of pain associated with the vaginal bleeding.
Painful bleeding points toward placental abruption or uterine rupture, whereas painless bleeding suggests placenta previa or vasa previa.
Pain is a primary differentiating factor in third-trimester bleeding etiologies.
2
Evaluate the timing and triggers of the symptoms in relation to fetal heart rate changes.
Profound fetal bradycardia immediately after membrane rupture strongly indicates vasa previa, due to the tearing of aberrant fetal vessels.
Identifying the precipitating event helps isolate the exact etiology.
3
Consider the patient's obstetric history and intrapartum findings.
A history of prior cesarean delivery combined with sudden loss of contractions and fetal station confirms uterine rupture.
Uterine rupture almost exclusively occurs in patients with a scarred uterus and presents with a classic loss of uterine tone during labor.

Key Concept

Differentiating etiologies of third-trimester bleeding and intrapartum emergencies based on classic clinical features.

Matches

Show answer & explanation

Answer

1 matches with Cervical conization. 2 matches with Exploratory laparotomy with cytoreductive surgery. 3 matches with Total extrafascial hysterectomy. 4 matches with Radical partial vulvectomy.
Each specific surgical intervention accurately aligns with the standardized clinical guidelines (ACOG/SGO) tailored to the respective patient's precise pathology, depth of invasion, menopausal status, and fertility goals.

Step-by-Step Solution

1
Analyze the clinical staging for the young patient with cervical microinvasion.
Identify Stage IA1 squamous cell carcinoma in a nulligravid patient.
Fertility-sparing surgery (cervical conization) is the standard of care for Stage IA1 disease without LVSI, avoiding unnecessary hysterectomy.
2
Evaluate the patient with a large adnexal mass, ascites, and omental nodularity.
Recognize a high suspicion for advanced-stage ovarian cancer.
Maximal cytoreductive debulking via exploratory laparotomy improves chemotherapy efficacy and overall survival in advanced epithelial ovarian cancer.
3
Assess the postmenopausal woman with complex atypical hyperplasia.
Recognize a high-risk precancerous lesion (EIN) with significant potential for concurrent malignancy.
Due to the high risk of occult adenocarcinoma, definitive management requires total extrafascial hysterectomy with bilateral salpingo-oophorectomy.
4
Determine surgical needs for the patient with a 2.5-cm vulvar lesion and 3 mm invasion.
Identify early invasive vulvar squamous cell carcinoma requiring nodal assessment.
Lesions invading >1 mm into the stroma mandate radical partial vulvectomy along with inguinofemoral lymph node evaluation to rule out metastasis.

Key Concept

Surgical management in Gynecologic Oncology is strictly dictated by tumor origin, precise staging criteria (e.g., depth of invasion), patient age, and fertility-sparing considerations.

Match each clinical presentation of a suspected gynecologic infection with its most likely diagnosis and corresponding management strategy.

Click a left item, then click its matching right item

Items

A patient presents with a malodorous, frothy, yellow-green vaginal discharge. Pelvic examination reveals punctate macular hemorrhages on the cervix. Vaginal pH is measured at 6.0.
A patient reports an off-white, thin, homogeneous vaginal discharge with a noticeable amine odor after intercourse. Wet mount microscopy reveals vaginal epithelial cells with stippled, indistinct margins.
A patient complains of intense vulvovaginal pruritus. Examination shows marked vulvar erythema and a thick, clumpy, white, adherent vaginal discharge. Vaginal pH is 4.0.
A patient is evaluated for new-onset postcoital spotting. Speculum examination reveals a friable cervix with a mucopurulent exudate visible at the external os. Vaginal pH is 4.2.

Matches

Show answer & explanation

Answer

The clinical presentations correctly pair with their diagnoses and management based on pH, discharge qualities, and microscopic findings: the frothy discharge with elevated pH matches Trichomonas; the clue cells and amine odor match Bacterial Vaginosis; the clumpy discharge with normal pH matches Candida; and the friable cervix with mucopurulent discharge matches Endocervicitis.
Each clinical vignette provides classic hallmark findings for a specific gynecologic infection, allowing for precise pairing with the etiologic agent. Furthermore, recognizing whether the infection is a dysbiosis (like bacterial vaginosis or candidiasis) versus a sexually transmitted infection (like trichomoniasis or chlamydial cervicitis) is critical for determining whether partner treatment is required.

Step-by-Step Solution

1
Evaluate the clinical findings in the first presentation.
Identified frothy yellow-green discharge, punctate cervical hemorrhages, and pH of 6.0.
These are the classic signs of Trichomonas vaginalis, which dictates systemic treatment for both the patient and sexual partners.
2
Evaluate the clinical findings in the second presentation.
Identified thin homogeneous discharge, positive amine odor, and clue cells.
These fulfill Amsel criteria for bacterial vaginosis. Because BV is a dysbiosis and not a classic STI, partner treatment is not recommended.
3
Evaluate the clinical findings in the third presentation.
Identified intense pruritus, thick clumpy discharge, and a normal pH of 4.0.
A normal pH (<4.5) in the setting of vulvar erythema and cottage cheese-like discharge is diagnostic of vulvovaginal candidiasis, requiring antifungal therapy.
4
Evaluate the clinical findings in the fourth presentation.
Identified postcoital spotting, friable cervix, mucopurulent exudate, and normal vaginal pH.
These findings localize the infection to the cervix rather than the vagina. Endocervicitis (commonly due to Chlamydia trachomatis) requires targeted antibiotic therapy and partner treatment.

24-year-old breastfeeding mother at 3 weeks postpartum who prefers taking a daily medication

Matches

Show answer & explanation

Answer

The 22-year-old with facial hair should receive the Combined oral contraceptive pill. The 38-year-old heavy smoker should receive the Copper intrauterine device. The 28-year-old with heavy periods should receive the Levonorgestrel-releasing intrauterine device. The 3-week postpartum breastfeeding mother should receive the Progestin-only pill.
Each contraceptive method precisely matches the patient's comorbidities and preferences. The combined oral contraceptive treats hyperandrogenism in PCOS. The copper IUD avoids the catastrophic cardiovascular risks of estrogen in older smokers. The levonorgestrel IUD directly treats heavy menstrual bleeding. The progestin-only pill safely provides daily contraception for early postpartum breastfeeding patients.

Step-by-Step Solution

1
Evaluate the 22-year-old with hirsutism and irregular menses.
Recognize signs of polycystic ovary syndrome (PCOS).
Combined oral contraceptives are the preferred initial management to lower free androgens and regulate the cycle.
2
Evaluate the 38-year-old smoker.
Identify that age over 35 and smoking is an absolute contraindication to estrogen.
To provide long-acting, hormone-free contraception without cardiovascular risk, the Copper intrauterine device is selected.
3
Evaluate the 28-year-old with heavy, painful bleeding.
Identify the need for a method that provides excellent contraception while treating menorrhagia.
The Levonorgestrel-releasing intrauterine device thins the endometrium, drastically reducing menstrual blood loss.
4
Evaluate the breastfeeding mother at 3 weeks postpartum.
Identify that early postpartum status (<1 month) restricts the use of estrogen.
The Progestin-only pill provides safe, daily contraception that does not increase thromboembolism risk or interfere with milk supply.

Evaluate the patient presenting with bloody nipple discharge.
Matched with Intraductal papilloma.
It is the most common cause of bloody nipple discharge in the absence of a coexisting mass.
2
Assess the presentation of an erythematous breast with peau d'orange failing to resolve on antibiotics.
Matched with Inflammatory breast cancer.
Dermal lymphatic invasion causes peau d'orange, and failure to respond to antibiotics differentiates it from infectious mastitis.
3
Analyze the young female patient with a highly mobile, rubbery mass.
Matched with Fibroadenoma.
These are the classic physical examination features of this benign solid tumor.
4
Identify the cause of bilateral cyclical breast pain and diffuse nodularity.
Matched with Fibrocystic changes.
Symptoms that classically fluctuate with the menstrual cycle suggest a benign physiologic response.
5
Evaluate the patient with a hard, fixed mass and skin dimpling.
Matched with Invasive ductal carcinoma.
Skin dimpling indicates suspensory ligament involvement, which is highly suspicious for an invasive malignancy.

Items

A 42-year-old woman undergoes a core needle biopsy of an indeterminate mammographic density. Pathology reveals lobular carcinoma in situ (LCIS).
A 50-year-old woman undergoes an excisional biopsy of a palpable breast mass with clear margins. Pathology confirms lobular carcinoma in situ (LCIS).
A 35-year-old woman presents with spontaneous, unilateral, bloody nipple discharge. Physical examination, mammography, and ultrasound are completely normal.
A 28-year-old lactating woman presents with a 4-cm, tender, fluctuant breast mass and fever despite 3 days of appropriate oral antibiotic therapy.
A 54-year-old asymptomatic woman is found to have newly clustered pleomorphic microcalcifications in the right breast on a routine screening mammogram.

Matches

Show answer & explanation

Answer

The correct matches accurately pair specific clinical and histological presentations of breast pathology with their guideline-directed next steps in management.
Each presentation requires a highly specific intervention: LCIS on core biopsy requires excision to prevent understaging, while fully excised LCIS only needs surveillance. Pathologic discharge without imaging correlates requires duct excision. Abscesses are first managed by aspiration, and microcalcifications are sampled using stereotactic guidance.

Step-by-Step Solution

1
Evaluate the management of LCIS diagnosed via core needle biopsy.
Identify that surgical excisional biopsy is required.
Core needle biopsy may miss adjacent DCIS or invasive cancer; excisional biopsy is needed to rule out upstaging.
2
Evaluate the management of LCIS fully excised with clear margins.
Identify that surveillance and discussion of chemoprevention is the appropriate next step.
Completely excised LCIS is a risk marker, not a true malignancy, and does not require further surgery or radiation.
3
Evaluate the workup for pathologic nipple discharge with negative imaging.
Identify subareolar duct excision as the necessary intervention.
A physical sample is needed to diagnose underlying pathology (e.g., intraductal papilloma) when imaging cannot locate a target.
4
Evaluate the treatment for a lactational breast abscess.
Identify ultrasound-guided needle aspiration as first-line therapy.
Needle aspiration is preferred over incision and drainage for breast abscesses due to reduced morbidity and continued ability to breastfeed.
5
Evaluate the workup for suspicious mammographic microcalcifications.
Identify stereotactic core needle biopsy as the correct step.
Stereotactic guidance utilizes mammography to successfully target calcifications that are typically invisible on ultrasound.

Key Concept

Management of breast disorders requires differentiating the diagnostic algorithms for non-palpable imaging abnormalities, pathologic nipple discharge, breast infections, and the specific surgical implications of LCIS based on the biopsy method.
Question 716Question →

Match each clinical presentation to the most likely underlying neurocognitive etiology.

Click a left item, then click its matching right item

Items

A patient exhibits profound early changes in personality, inappropriate social conduct, and hyperorality without initial significant memory loss.
A patient experiences an abrupt, step-wise deterioration in executive function following multiple ischemic events, accompanied by asymmetric reflex abnormalities.
A patient reports vivid recurrent formed visual hallucinations and REM sleep behavior disorder, alongside spontaneous parkinsonian features.
A patient develops a progressive triad of gait apraxia, sudden urinary urgency, and insidious cognitive slowing.

Matches

Show answer & explanation

Answer

The presentations match as follows: early personality changes pair with Frontotemporal neurocognitive disorder; step-wise ischemic decline pairs with Vascular neurocognitive disorder; visual hallucinations with parkinsonism pairs with Neurocognitive disorder with Lewy bodies; and the triad of gait apraxia, urinary urgency, and cognitive slowing pairs with Normal pressure hydrocephalus.
Each neurocognitive etiology has highly specific, defining clinical features. Frontotemporal disease targets frontal lobe executive and behavioral regulation; vascular disease manifests as discrete, step-wise losses mapping to stroke territories; Lewy body pathology uniquely generates visual hallucinations and parkinsonism; and normal pressure hydrocephalus mechanically impacts periventricular tracts causing a specific triad of gait, bladder, and cognitive symptoms.

Step-by-Step Solution

1
Analyze the first clinical presentation for distinguishing behavioral symptoms.
Identified prominent personality changes and hyperorality.
These are specific criteria for diagnosing frontotemporal neurocognitive disorder.
2
Evaluate the second presentation for onset and progression pattern.
Identified a step-wise decline associated with ischemic events.
Step-wise progression strongly indicates an underlying cerebrovascular etiology.
3
Review the third presentation for specific neuropsychiatric and sleep disturbances.
Identified visual hallucinations, REM sleep behavior disorder, and parkinsonism.
These form the classic core criteria for neurocognitive disorder with Lewy bodies.
4
Assess the fourth presentation for the classic symptomatic triad.
Identified gait apraxia, urinary incontinence, and cognitive decline.
This triad suggests impaired cerebrospinal fluid reabsorption, pointing to normal pressure hydrocephalus.

Match each pharmacological agent used in psychiatric practice with its characteristic adverse effect profile or specific clinical warning regarding its use in bipolar disorder.

Click a left item, then click its matching right item

Items

Lithium
Valproate
Quetiapine
Sertraline

Matches

Show answer & explanation

Answer

Lithium pairs with renal/thyroid monitoring; Valproate pairs with hepatotoxicity and neural tube defects; Quetiapine pairs with metabolic syndrome monitoring; Sertraline pairs with the risk of precipitating a manic switch.
Each medication plays a specific role in psychiatric care and has a uniquely identifiable risk profile. Lithium affects the kidneys and thyroid. Valproate affects the liver and platelets, and is teratogenic. Quetiapine causes metabolic derangements. Sertraline, while an effective antidepressant, can dangerously precipitate mania in bipolar patients.

Step-by-Step Solution

1
Evaluate the specific organ toxicity and monitoring requirements for the classic mood stabilizers.
Lithium requires renal (creatinine) and thyroid (TSH) monitoring. Valproate requires hepatic function and platelet monitoring, and carries neural tube defect risks.
Mood stabilizers have distinct pharmacokinetic pathways and long-term toxicity profiles that are highly tested core concepts.
2
Identify the primary adverse effects of second-generation antipsychotics used in bipolar disorder.
Quetiapine is strongly linked to weight gain, dyslipidemia, and hyperglycemia.
Atypical antipsychotics are central to bipolar treatment, but their metabolic effects necessitate strict longitudinal monitoring.
3
Determine the clinical consequence of using unopposed antidepressants in a patient with bipolar disorder.
Sertraline (an SSRI) can induce a manic switch if given without a concurrent mood stabilizer.
Antidepressant monotherapy is a classic prescribing error in patients with bipolar depression.

A 19-year-old student wears eccentric, mismatched clothing in summer, claims to predict the future via telepathy, and lacks close friends outside his immediate family.

Matches

Show answer & explanation

Answer

The correct matches align the executive with Narcissistic personality disorder, the accountant with Paranoid personality disorder, the developer with Avoidant personality disorder, and the student with Schizotypal personality disorder.
Each clinical vignette is uniquely designed to highlight the textbook diagnostic criteria of a specific personality disorder according to DSM-5, relying on core features: grandiosity (Narcissistic), distrust (Paranoid), fear of rejection (Avoidant), and magical thinking (Schizotypal).

Step-by-Step Solution

1
Identify the core behavioral pattern of the 41-year-old executive.
The traits of entitlement, superiority, and demand for admiration point directly to Narcissistic personality disorder.
Recognizing Cluster B traits of grandiosity differentiates this from other disorders.
2
Identify the core behavioral pattern of the 52-year-old accountant.
The unfounded suspicions, mistrust of others, and guardedness are classic for Paranoid personality disorder.
Recognizing Cluster A traits of distrust distinguishes it from delusional disorder, as the suspicions are pervasive rather than a single fixed delusion.
3
Identify the core behavioral pattern of the 31-year-old developer.
The intense fear of rejection and feelings of inadequacy despite a desire for connection point to Avoidant personality disorder.
This cluster C trait differentiates Avoidant personality disorder from Schizoid personality disorder, where the patient genuinely does not desire relationships.
4
Identify the core behavioral pattern of the 19-year-old student.
The magical thinking, eccentric appearance, and interpersonal deficits match Schizotypal personality disorder.
Recognizing Cluster A odd/eccentric traits combined with cognitive distortions confirms the diagnosis without the frank psychosis seen in schizophrenia.

Key Concept

Lithium
Valproate
Lamotrigine
Sertraline monotherapy

Matches

Show answer & explanation

Answer

Lithium matches with thyroid/renal monitoring; Valproate matches with liver/CBC monitoring; Lamotrigine matches with slow titration for rash risk; Sertraline monotherapy matches with the risk of precipitating acute mania.
Effective pharmacotherapy for bipolar disorder requires careful selection and monitoring of medications. Lithium necessitates renal and thyroid monitoring due to risks of nephropathy and hypothyroidism. Valproate requires hepatic and hematologic monitoring due to risks of hepatotoxicity and thrombocytopenia. Lamotrigine requires slow dose titration to avoid life-threatening Stevens-Johnson syndrome. Crucially, SSRI monotherapy (like sertraline) is contraindicated in bipolar disorder as it can precipitate manic episodes.

Step-by-Step Solution

1
Identify the primary risk of using antidepressant monotherapy (Sertraline) in bipolar disorder.
It carries a high risk of precipitating mania.
Antidepressants without concurrent mood stabilizers can cause mood destabilization in bipolar patients.
2
Determine the baseline monitoring for Lithium.
Baseline TSH and renal function (BUN/creatinine) are needed.
Lithium is associated with hypothyroidism and renal toxicity (tubulointerstitial nephropathy).
3
Determine the baseline monitoring for Valproate.
Baseline LFTs and CBC are needed.
Valproate carries risks of severe hepatotoxicity, pancreatitis, and thrombocytopenia.
4
Determine the monitoring for Lamotrigine.
No specific routine labs, but very slow titration is required.
Lamotrigine is associated with a risk of Stevens-Johnson syndrome, which is dose-dependent.

Key Concept

Pharmacologic management of bipolar disorder, including baseline monitoring for mood stabilizers and the contraindication of antidepressant monotherapy.

Matches

Show answer & explanation

Answer

The teacher is matched with Obsessive-Compulsive Personality Disorder, the data analyst with Schizoid Personality Disorder, the attorney with Narcissistic Personality Disorder, and the artist with Avoidant Personality Disorder.
Each clinical vignette highlights the quintessential features of a specific personality disorder. Obsessive-Compulsive Personality Disorder is marked by task-impairing perfectionism. Schizoid Personality Disorder is defined by an innate lack of desire for social connection. Narcissistic Personality Disorder is characterized by grandiosity and lack of empathy. Avoidant Personality Disorder is defined by extreme sensitivity to rejection leading to social withdrawal despite an underlying desire for connection.

Step-by-Step Solution

1
Analyze the middle school teacher's presentation.
Identified extreme perfectionism, orderliness, and rigidity that directly impairs task completion.
These are the hallmark criteria for Obsessive-Compulsive Personality Disorder, distinguishing it from healthy conscientiousness or general perfectionism.
2
Analyze the data analyst's presentation.
Identified a complete lack of desire for relationships, preference for solitary activities, and social detachment.
This pattern isolates the diagnosis to Schizoid Personality Disorder, ruling out anxiety-driven isolation.
3
Analyze the attorney's presentation.
Identified grandiosity, lack of empathy, entitlement, and exploitative/arrogant interpersonal behavior.
These are the core diagnostic features of Narcissistic Personality Disorder.
4
Analyze the artist's presentation.
Identified occupational avoidance driven purely by an intense fear of negative evaluation and rejection.
This distinguishes Avoidant Personality Disorder, as the isolation is driven by deep-seated anxiety and feelings of inadequacy rather than a lack of interest in socializing.

Key Concept

Differentiating personality disorders based on core interpersonal dynamics, defense mechanisms, and ego-syntonic behavioral patterns.
