Obstetrics and Gynecology

A 32-year-old woman, gravida 1, para 0, abortus 1, presents to the clinic with an 8-month history of amenorrhea. Ten months ago, she underwent a surgical dilation and curettage for a first-trimester incomplete abortion. Over the past year, she has also been training for a marathon and runs approximately 40 miles per week. Her BMI is 18.2 kg/m². Vital signs are within normal limits. Physical examination reveals normal secondary sexual characteristics and no galactorrhea, hirsutism, or acne. Pelvic examination is unremarkable. The physician decides to initiate a comprehensive workup for secondary amenorrhea.

Arrange the following diagnostic steps in the most appropriate sequential order for evaluating this patient's condition.

A $65$-year-old woman comes to the clinic reporting a single episode of bright red blood on her undergarments two days ago. She has not had a menstrual period in fourteen years. Her medical history is notable for obesity, type 2 diabetes mellitus, and severe genitourinary syndrome of menopause. Three weeks ago, she began using a low-dose estradiol vaginal ring for her genitourinary symptoms. Her body mass index is $33\text{ kg/m}^2$. Vital signs are within normal limits. Pelvic examination reveals a correctly positioned vaginal ring, improved mucosal hydration, and no visible lacerations or active bleeding in the vaginal vault. Ultrasound imaging of the pelvis demonstrates a homogeneously thickened uterine stripe measuring $7\text{ mm}$ and bilateral normal-appearing adnexa. Which of the following is the most appropriate next step in management?

An obstetrician is managing the vaginal delivery of a macrosomic fetus in a patient with gestational diabetes. After the fetal head is delivered, it immediately retracts tightly against the maternal perineum. Routine downward traction fails to deliver the anterior shoulder. Arrange the following clinical interventions in the correct sequential order, from the immediate first steps to the maneuver of absolute last resort, for managing this obstetric emergency.

During a routine evaluation, a 54-year-old teacher describes increasingly disruptive episodes of spontaneous, large-volume urinary leakage that occur immediately following a sudden, overwhelming urge to urinate. Her pelvic examination reveals normal anterior and posterior vaginal support, a negative cough stress test, and a post-void residual volume of 35 mL. Urinalysis is unremarkable. Assuming the patient remains highly symptomatic and fully adheres to each prescribed intervention without experiencing intolerable side effects, arrange the following therapeutic interventions in the correct chronological sequence of escalation according to established urogynecology guidelines.

Continuous, involuntary leakage of clear vaginal fluid is the chief complaint of a parous female evaluated in the outpatient gynecology clinic. Her surgical history is significant for a difficult total laparoscopic hysterectomy performed fourteen days prior due to an enlarged fibroid uterus. The patient states she is constantly damp despite using absorbent pads, yet she maintains the ability to voluntarily urinate small amounts into the toilet. Vital signs and basic laboratory results are unremarkable. Based on the suspected diagnosis, arrange the following clinical interventions in the correct chronological sequence from initial evaluation to definitive management.

A 34-year-old woman comes to the urogynecology clinic complaining of chronic, severe suprapubic pelvic pain that worsens as her bladder fills and is temporarily relieved by voiding. She reports urinating up to 15 times during the day and 4 times at night. Over the past year, she has received three courses of antibiotics for suspected cystitis, but her symptoms persisted and urine cultures were consistently negative. Pelvic examination demonstrates tenderness at the bladder base but no anterior or posterior vaginal wall prolapse.

Assume a clinical diagnosis of interstitial cystitis/bladder pain syndrome (IC/BPS). Arrange the following diagnostic and management steps in the correct sequential order according to standard escalating treatment guidelines, from initial presentation to refractory disease.

A 24-year-old nulliparous woman presents to the clinic after discovering a firm, mobile, and painless lump in her left breast. Arrange the following steps in the correct sequential order for the standard evaluation and management of this patient's new breast mass, from the initial encounter to the final disposition.

A 42-year-old female patient is evaluated in the outpatient surgical clinic on her third postoperative day. She reports new-onset, right-sided lower back pain accompanied by subjective fevers. Three days prior, she underwent an uncomplicated laparoscopic hysterectomy to treat symptomatic, large uterine leiomyomas. Her past medical history is notable only for mild asthma. Her current temperature is 38.3°C (100.9°F), blood pressure is 122/76 mm Hg, and heart rate is 94/min. Physical examination demonstrates marked tenderness to percussion over the right costovertebral angle. Her abdomen is soft and non-distended, with well-healing laparoscopic port sites without erythema or induration. Urinalysis reveals 1 to 2 leukocytes per high-power field, negative nitrites, and no red blood cells. Which of the following is the most appropriate next step in the management of this patient?

A $27$-year-old nulliparous woman at $40$ weeks gestation presents to the obstetric unit with spontaneous onset of painful uterine contractions. Her pregnancy has been uncomplicated. Six hours after admission, she is in active labor. Maternal vital signs are within normal limits. The fetal heart rate tracing demonstrates a baseline of $135$/min with moderate variability. However, the tracing displays recurrent, rapid drops in the fetal heart rate down to $75$/min. These drops last for $40$ to $60$ seconds before abruptly returning to baseline, and they do not consistently align with the peak of uterine contractions. Uterine contractions are occurring every $3$ minutes.

In response to these findings, the attending nurse assists the patient into the left lateral decubitus position, initiates a $500$ mL intravenous fluid bolus, and applies supplemental oxygen via face mask. Despite these measures, the fetal heart rate pattern persists over the next $30$ minutes. A sterile vaginal examination shows the cervix is $6$ cm dilated and completely effaced, with the fetal head at $-1$ station. No pulsating tissue is felt through the dilated cervix. Which of the following is the most appropriate next step in the management of this patient?

A previously healthy 33-year-old female is evaluated in the clinic for a tender mass in her right breast, first noticed 5 days ago. The pain is described as a localized ache that worsens with physical pressure. Her menstrual cycles are regular, and her last menstrual period was 2 weeks ago. She has no personal or family history of breast disease. Vital signs are within normal limits. Physical examination reveals a 3.5-cm, smooth, firm, and tender mobile mass in the upper outer quadrant of the right breast. There is no overlying skin erythema, dimpling, or nipple discharge. A targeted breast ultrasound is performed, which demonstrates a well-circumscribed, thin-walled, anechoic structure with posterior acoustic enhancement.

Which of the following is the most appropriate next step in management to alleviate this patient's symptoms?

Match each characteristic presentation of nipple discharge to its most likely underlying etiology.

Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity. Identifying the underlying etiology rapidly through physical examination is critical for directing appropriate intervention. Pair each distinct clinical presentation of severe postpartum bleeding with its corresponding primary etiology.

A 70-year-old multiparous woman undergoes a right-sided sacrospinous ligament suspension for symptomatic vaginal vault prolapse following a hysterectomy performed 15 years ago. Two hours after arriving in the post-anesthesia care unit, she complains of excruciating, sharp, burning pain in her right gluteal region that radiates to the right perineum and labia majora. She is highly distressed and rates the pain as $10$ on a $10$-point scale despite receiving adequate doses of intravenous morphine. Vital signs show a temperature of $37.1^\circ\text{C}$ ($98.8^\circ\text{F}$), blood pressure of $135/85\text{ mmHg}$, and heart rate of $98/\text{min}$. Neurological examination reveals normal motor strength in her lower extremities bilaterally, with intact patellar and Achilles reflexes. However, there is marked hyperalgesia over the right perianal and perineal area. The surgical site shows no active vaginal bleeding, and her abdomen is soft and non-tender. Which of the following is the most appropriate next step in management?

A 24-year-old woman is evaluated in the outpatient clinic for persistent vaginal discharge and vulvar pruritus. Three weeks ago, she presented with a copious, malodorous, yellow-green vaginal discharge and was diagnosed with a vaginal infection. At that time, she was treated with a single 2-gram dose of oral metronidazole. She reports that her symptoms improved for a few days but subsequently returned to their initial severity. The patient is in a monogamous relationship; her male partner was simultaneously treated with a single 2-gram dose of oral metronidazole, and they abstained from sexual activity for 10 days following treatment. Vital signs are within normal limits. Pelvic examination reveals a frothy, yellowish-green vaginal pooling and diffuse punctate hemorrhages on the exocervix. The vaginal pH is 6.5. Microscopic evaluation of a saline wet mount demonstrates numerous polymorphonuclear leukocytes and motile, flagellated organisms slightly larger than white blood cells. Which of the following is the most appropriate next step in pharmacotherapy for this patient?

Match each clinical presentation to the most likely underlying urogynecologic diagnosis.

A 26-year-old nulliparous woman undergoes an uncomplicated suction dilation and curettage for a histologically confirmed complete hydatidiform mole. Arrange the following clinical steps and milestones in the correct chronological sequence for her standard pathway, culminating in the management of low-risk gestational trophoblastic neoplasia (GTN).

A 50-year-old woman is evaluated in the post-anesthesia care unit 4 hours after undergoing a laparoscopic-assisted vaginal hysterectomy for medically refractory adenomyosis. The operative report indicates that the procedure was technically challenging due to extensive pelvic adhesions, but no immediate intraoperative complications were noted. The patient now reports severe, worsening abdominal pain and lightheadedness. Her temperature is 37.6°C (99.7°F), blood pressure is 78/42 mm Hg, pulse is 132/min, and respiratory rate is 22/min. Physical examination reveals a distended, rigid abdomen with diffuse guarding and rebound tenderness. Speculum examination shows the vaginal cuff is intact with only scant serosanguinous drainage. Point-of-care laboratory testing shows a hemoglobin level of 7.2 g/dL, compared to a preoperative baseline of 12.1 g/dL. Which of the following is the most appropriate next step in the management of this patient?

Match each patient's clinical presentation of a gynecologic infection with the most appropriate, guideline-concordant management strategy.

A 26-year-old woman is evaluated on postoperative day 3 following an uncomplicated primary cesarean delivery. She reports bilateral breast pain and swelling that began earlier today. She is exclusively breastfeeding her newborn. Her temperature is 37.9°C (100.2°F), blood pressure is 112/72 mm Hg, and pulse is 84/min. Physical examination demonstrates bilateral, symmetrically firm, warm, and tender breasts without focal erythema, induration, or fluctuance. The cesarean abdominal incision is clean, dry, and intact with no surrounding erythema. The uterine fundus is firm and palpable below the umbilicus. Which of the following is the most appropriate next step in management?

A 76-year-old woman, G3P3, comes to the clinic due to a 3-month history of involuntary, continuous leakage of urine. She describes the leakage as a constant "dribbling" and reports a persistent sensation that she cannot completely empty her bladder. The patient voids frequently in small amounts during the day and wakes up 3 to 4 times a night to urinate. Medical history is significant for a 20-year history of type 2 diabetes mellitus complicated by peripheral neuropathy. Vital signs are within normal limits. Physical examination reveals decreased sensation to pinprick in the bilateral feet. Abdominal examination reveals a palpable, smooth, suprapubic mass that is dull to percussion. Pelvic examination shows normal vaginal mucosa with no evidence of pelvic organ prolapse. Urinalysis is unremarkable. Which of the following is the most appropriate next step in management?
