OBGYN Flashcards
A 23-year-old female complains of lower abdominal and pelvic pain, increased vaginal discharge, and postcoital bleeding. Her pain worsens during intercourse, and is accompanied by occasional nausea and vomiting and a feverish feeling. She is sexually active with several male partners.
A physical examination is remarkable for an oral temperature of 38.6°C (101.5°F), cervical motion tenderness, adnexal tenderness without a mass, and a prominent cervical discharge. Office laboratory results include an elevated erythrocyte sedimentation rate and an elevated WBC count. Saline microscopy of vaginal secretions shows abundant numbers of WBCs but is negative for Trichomonas vaginalis and bacterial vaginosis. You order nucleic-acid amplification tests for Chlamydia trachomatis and Neisseria gonorrhoeae.
Which one of the following would be most appropriate at this point? (check one)
- Treatment based on clinical findings
- Treatment when results of testing for Chlamydia trachomatis and Neisseria gonorrhoeae are available
- Transvaginal ultrasonography
- Pelvic CT
- Laparoscopy
Treatment based on clinical findings
The diagnosis of pelvic inflammatory disease (PID) is based primarily on the clinical evaluation. Significant consequences can occur if treatment is delayed. Physicians should therefore treat on the basis of clinical judgment without waiting for confirmation from laboratory or imaging tests (SOR B). No single symptom, physical finding, or laboratory test is sensitive or specific enough to definitively diagnose PID (SOR C). Clinical diagnosis alone based on the history, physical examination, and office laboratory results is 87% sensitive, transvaginal ultrasonography is 30% sensitive, and laparoscopy is 81% sensitive but unnecessarily invasive and not cost-effective. A study examining the diagnostic performance of CT in acute PID concluded that the overall sensitivity of CT is poor.
A 75-year-old female sees you because of a bulge at the vaginal opening. A pelvic examination confirms descent of the vaginal wall to just beyond the hymen. This protrusion is bothering her and interfering with her quality of life. She has had two vaginal deliveries. She is sexually active and has not had any pelvic surgery.
Which one of the following would be the most appropriate initial treatment for this problem? (check one)
- Kegel exercises
- A ring pessary
- A space-occupying pessary
- Hysteropexy
- Hysterectomy
A Ring Pessary
Pessaries are considered first-line treatment for pelvic organ prolapse (SOR C). Ring pessaries provide support and are the initial choice in most circumstances. Sexual intercourse can still occur with a ring pessary, which can be inserted and removed by the patient. Space-occupying pessaries are associated with more vaginal discharge and irritation and do not allow for sexual intercourse. While they can improve stress and urge urinary incontinence, Kegel exercises do not treat pelvic organ prolapse. Surgery, including hysterectomy or hysteropexy that conserves the uterus, can be considered after first-line treatment with a pessary.
A 34-year-old female consults you because of excessive body and facial hair. She has a normal body weight, no other signs of virilization, and regular menses. She had a bilateral tubal ligation 4 years ago.
Which one of the following would be the most appropriate treatment for her mild hirsutism? (check one)
Leuprolide
Metformin (Glucophage)
Prednisone
Spironolactone (Aldactone)
Spironolactone (Aldactone)
Antiandrogens such as spironolactone, along with oral contraceptives, are recommended for the treatment of hirsutism in premenopausal women (SOR C). Women should avoid becoming pregnant while on spironolactone because of the potential for teratogenic effects. In addition to having side effects, prednisone is only minimally helpful for reducing hirsutism by suppressing adrenal androgens. Leuprolide, although better than placebo, has many side effects and is expensive. Metformin can be used to treat patients with polycystic ovary syndrome, but this patient does not meet the criteria for this diagnosis.
A 17-year-old female with a history of morbid obesity sees you to discuss contraceptive options. She is heterosexual and is currently sexually active with one male partner. She has heavy irregular periods and associated anemia and is interested in a contraceptive option that will both provide reliable birth control and decrease her menstrual blood loss. She recently had negative tests for HIV, gonorrhea, and Chlamydia at a local health department. Her examination is unremarkable except for a weight of 136 kg (300 lb) and a BMI of 50 kg/m2.
Which one of the following would be the best option for contraception for this patient? (check one)
A diaphragm with spermicide
The norelgestromin/ethinyl estradiol transdermal system (Ortho Evra)
The levonorgestrel-releasing intrauterine system (Mirena IUD)
Medroxyprogesterone acetate (Depo-Provera)
The levonorgestrel-releasing intrauterine system (Mirena IUD)
This patient has heavy menstrual bleeding, associated anemia, and morbid obesity, all of which need to be taken into consideration when choosing contraception. Medroxyprogesterone acetate can contribute to weight gain and thus should not be the first choice in this individual. The norelgestromin/ethinyl estradiol transdermal system is not recommended in patients with a weight over 90 kg and thus is not an option for this patient. The levonorgestrel-releasing intrauterine system would be the best option, given the associated significant decrease in menstrual blood loss after the first 3 months of insertion and equal effectiveness in obese and non-obese patients. Although a diaphragm is an option, it will not decrease her menstrual blood loss.
A 30-year-old otherwise healthy female has concerns about her menses and fertility. Her last menstrual period was 8 months ago when she stopped taking oral contraceptive pills (OCPs). In her teens and early twenties she had irregular, sporadic periods. Four years ago she developed menometrorrhagia and resultant iron deficiency anemia; this was corrected with the use of OCPs. She is now interested in becoming pregnant. Her physical examination, including a gynecologic examination, is normal. A urine pregnancy test is negative and her TSH level is in the normal range.
Which one of the following is the most appropriate next step? (check one)
A CBC and metabolic panel
Serum LH and FSH levels
Karyotype analysis
Pelvic ultrasonography
Serum LH and FSH levels
This patient suffers from secondary amenorrhea (defined as the cessation of regular menses for 3 months or irregular menses for 6 months). The most common causes of secondary amenorrhea are polycystic ovary syndrome, primary ovarian failure, hypothalamic amenorrhea, and hyperprolactinemia. With a normal physical examination, negative pregnancy test, and no history of chronic disease, a hormonal workup is indicated, including TSH, LH, and FSH levels (SOR C).
A hormonal challenge with medroxyprogesterone to provoke withdrawal bleeding is used to assess functional anatomy and estrogen levels (SOR C). However, it has poor specificity and sensitivity for ovarian function and a poor correlation with estrogen levels.
Pelvic ultrasonography is indicated in the workup of primary amenorrhea to confirm the presence of a uterus and detect structural abnormalities of the reproductive organs. Likewise, karyotyping can be used for patients with primary amenorrhea, as conditions such as Turner’s syndrome and androgen insensitivity syndrome are due to chromosomal abnormalities.
A CBC and metabolic panel would not be initial considerations in the workup of amenorrhea unless the patient has a known chronic disease which may affect the results.
A 24-year-old gravida 4 para 2 with mild chronic hypertension and an uncomplicated pregnancy has just delivered a vigorous male by spontaneous vaginal delivery. She is noted to have heavy vaginal bleeding and a bimanual examination reveals a soft, poorly contracted uterus. Her temperature is 37.1°C (98.8°F), blood pressure 158/92 mm Hg, pulse rate 105 beats/min, and oxygen saturation 95% on room air.
Which one of the following uterotonic agents is CONTRAINDICATED in the management of this patient’s postpartum hemorrhage? (check one)
Oxytocin (Pitocin)
Methylergonovine
Carboprost tromethamine (Hemabate)
Misoprostol (Cytotec
Methylergonovine
Uterotonics are the first-line treatment for postpartum hemorrhage in patients with decreased uterine tone. While all of the uterotonic agents listed are options for the management of postpartum hemorrhage, methylergonovine should be avoided if the patient is hypertensive. It is an ergot alkaloid that causes generalized smooth muscle contraction and can raise blood pressure. Oxytocin and misoprostol do not have any contraindications. Carboprost tromethamine should be avoided in asthmatic patients and is relatively contraindicated if the patient has hepatic, renal, or cardiac disease.
A 23-year-old female presents with menstrual irregularity, increased facial hair, and acne. Your evaluation leads to a diagnosis of polycystic ovary syndrome.
Which one of the following is the first-line management for her constellation of symptoms? (check one)
Clomiphene (Clomid)
Hormonal contraceptives
Metformin (Glucophage)
Pioglitazone (Actos)
Spironolactone (Aldactone)
Hormonal contraceptives
Hormonal contraceptives are the first-line therapy for menstrual abnormalities, hirsutism, and acne in polycystic ovary syndrome. Clomiphene is used for infertility. Thiazolidinediones have an unfavorable risk-benefit ratio overall. Metformin is beneficial for metabolic/glycemic abnormalities and menstrual irregularities, but does not improve hirsutism or acne. Spironolactone may be used as an add-on to hormonal contraceptives for treatment of hirsutism and acne.
In a woman whose group B Streptococcus status is unknown, which one of the following is a risk factor requiring empiric intrapartum antibiotic prophylaxis against early-onset group B streptococcal infection in her newborn? (check one)
Fetal tachycardia
Delivery at less than 35 weeks gestation
Rupture of the membranes 12 hours before delivery
Gestational diabetes during the pregnancy
Use of vacuum extraction during delivery
Delivery at less than 35 weeks gestation
Of the choices listed, prematurity is the greatest risk factor for group B streptococcal infection. The most important risk would be signs or symptoms of sepsis in a neonate. The other conditions listed are not risk factors for early-onset GBS in neonates.
A 25-year-old female reports the absence of menses for the past 6 months. She is currently not taking any medications. You confirm that she is not pregnant and order additional laboratory testing. TSH, LH, and FSH levels are normal but she has an elevated prolactin level.
Which one of the following would be most appropriate at this point to further evaluate her pituitary gland? (check one)
A follow-up serum prolactin level in 4 weeks
A prolactin-stimulating hormone level
MRI of the pituitary
Head CT with intravenous contrast
MRI of the pituitary
Prolactin levels can be elevated because of a pituitary adenoma, medication side effects, hypothyroidism, or a mass lesion compromising normal hypothalamic inhibition. Elevated prolactin levels inhibit the secretion and effect of gonadotropins. In almost all patients with an elevated prolactin level, MRI of the pituitary is recommended to exclude the possibility of a pituitary adenoma (SOR C). This patient is not on any medications, essentially ruling out a pharmacologic trigger for her elevated prolactin.
A 24-year-old gravida 2 para 1 presents to your office for her first prenatal visit at 7 weeks gestation. You review her vaccine records and note that she received Tdap 1 year ago.
When should you recommend that she get her next Tdap? (check one)
Post partum
At this visit
Anytime after the first trimester
Between 27 and 36 weeks gestation
10 years after the last dose
Between 27 and 36 weeks gestation
Due to the increasing incidence of pertussis, the Centers for Disease Control and Prevention recommends that all pregnant women receive Tdap vaccine during every pregnancy regardless of when their last dose was. It is ideally administered between 27 and 36 weeks gestation to maximize the maternal antibody response and passive antibody transfer to the infant.
A 25-year-old primigravida presents at 28 weeks gestation for a routine prenatal visit. She is undecided about breastfeeding versus bottle feeding and asks if breastfeeding provides any benefits for her own health.
You advise her that breastfeeding would decrease her risk of later developing (check one)
colon cancer
diabetes mellitus
lung cancer
osteoarthiritis
recurrent respiratory infections
diabetes mellitus
Breastfeeding provides many health benefits to both the mother and the infant. Maternal benefits include a decreased risk of developing cardiometabolic disease, including diabetes mellitus, hypertension, and cardiovascular disease; a decreased risk of breast cancer and ovarian cancer; and a decreased risk of postpartum depression. A link has not been established between breastfeeding and a reduced risk of developing colon cancer or lung cancer or osteoarthritis later in life. While breastfeeding may reduce the infant’s risk of respiratory disease, this is not an expected benefit for the mother.
A 32-year-old primigravida at 36 weeks gestation complains of headaches. She denies vaginal bleeding, leakage of fluid, and contractions, and the fetus is moving normally. Her blood pressure is 155/100 mm Hg and a urinalysis shows 4+ protein. The rest of her examination is normal and a cervical examination shows 1 cm of dilation, 50% effacement, a soft consistency, anterior position, and –2 vertex station. Results of a preeclampsia panel are all in the normal range.
Which one of the following is the most appropriate management for this patient? (check one)
Start labetalol (Trandate) and discharge home on bed rest with close follow-up
Start magnesium sulfate and induce labor now
Start magnesium sulfate, administer corticosteroids, and induce labor in 48 hours
Start magnesium sulfate, lower blood pressure to 140/90 mm Hg, and induce labor at 37 weeks gestation
Arrange for urgent cesarean section
Start magnesium sulfate and induce labor now
This patient likely has severe preeclampsia based on her elevated blood pressure with 4+ protein on her urinalysis. Patients with severe preeclampsia near term should be placed on magnesium sulfate to prevent seizures, and labor should be induced immediately. An urgent cesarean section is not necessary. Corticosteroids have not been shown to improve neonatal outcomes when given after 34 weeks gestation. Elevated blood pressures can be managed with hydralazine and labetalol. Normalizing blood pressure is not recommended, but these drugs should be used when blood pressure is over 160/105 mm Hg.
A 35-year-old female presents for contraceptive counseling. Her last menstrual period was 3 weeks ago and she had unprotected sex 2 days ago. A pregnancy test is negative.
Which one of the following would be the most effective emergency contraceptive agent for this patient? (check one)
Oral levonorgestrel (Plan B One-Step)
Oral ulipristal (Ella)
Subcutaneous depot medroxyprogesterone acetate (Depo-Provera)
An etonogestrel subdermal implant (Nexplanon)
A copper IUD (Paragard)
A copper IUD (Paragard)
The copper IUD is the most effective form of emergency contraception with a pregnancy rate of 0.1%, followed by oral ulipristal with a pregnancy rate of 1.3%. Oral levonorgestrel is less effective than both with a pregnancy rate of 2.5%. Subcutaneous depot medroxyprogesterone acetate and the etonogestrel subdermal implant are not recommended as emergency contraceptives.
A 25-year-old female with hypothyroidism sees you for preconception counseling. Her thyroid problem has been well managed with levothyroxine (Synthroid), 75 !g daily, but she asks your advice about changing her treatment to something more natural now that she is planning to become pregnant.
Which one of the following is the best recommendation for this patient? (check one)
Continue the current dosage of levothyroxine
Reduce the current dosage of levothyroxine to 50 !g daily
Change to a comparable dosage of combination levothyroxine/L-triiodothyronine
Change to a comparable dosage of desiccated thyroid
Continue the current dosage of levothyroxine
Untreated hypothyroidism during pregnancy impairs fetal development and increases the risk of spontaneous miscarriage, prematurity, preeclampsia, gestational hypertension, and postpartum hemorrhage. These risks are mitigated by appropriate levothyroxine treatment. Levothyroxine/L¬triiodothyroxine combinations and desiccated thyroid preparations have the potential to correct maternal hypothyroidism, but the T4 level may still be too low to provide the transplacental delivery necessary for optimal fetal health. The most appropriate pregnancy planning advice is to continue the current dosage of levothyroxine with a plan for monthly monitoring of TSH and T4 during pregnancy, with the expectation that an increase in dosage may be required as the pregnancy progresses.
Which one of the following is consistent with best practices for prescribing hormonal contraception? (check one)
Delaying initiation until the patient’s next menstrual period to avoid incidental use in early pregnancy
Limiting prescription refills to 3 months at a time
Obtaining a thorough medical history to screen for contraindications
Requiring in-person visits rather than telehealth visits for contraceptive counseling due to the need for a gynecologic examination
Requiring patients to have an up-to-date Papanicolaou test and sexually transmitted infection screening
Obtaining a thorough medical history to screen for contraindications
There are many patient-related historical factors that may affect the safety and choice of hormonal contraception, but very few physical factors are likely to be found on examination that would not otherwise have been identified. Obtaining a thorough medical history is standard practice, but the Choosing Wisely campaign recommends against requiring a pelvic or other physical examination prior to prescribing oral contraceptives. It is unnecessary to wait to begin hormonal contraception until after the next menses, as inadvertent exposure to oral contraception will not harm an early pregnancy. Prescribing a 1-year supply of hormonal contraceptives improves adherence and lowers cost. There is broad consensus that sexually transmitted infection screening and Papanicolaou testing should not be required to prescribe contraception.
A 50-year-old male with difficult-to-control hypertension seeks your advice regarding progressive breast enlargement. Your examination reveals bilateral firm, glandular tissue in a concentric mass around the nipple-areola complex. You diagnose gynecomastia.
Which one of the following antihypertensive medications is most likely to cause this problem? (check one)
Doxazosin (Cardura)
Hydrochlorothiazide
Lisinopril (Prinivil, Zestril)
Losartan (Cozaar)
Spironolactone (Aldactone)
Spironolactone (Aldactone)
Except for persistent pubertal gynecomastia, medication use and substance use are the most common causes of nonphysiologic gynecomastia. Common medication-related causes include the use of antipsychotic agents, antiretroviral drugs, or prostate cancer therapies. Spironolactone also has a high propensity to cause gynecomastia; other mineralocorticoid receptor antagonists, such as eplerenone, have not been associated with similar effects. Discontinuing the contributing agent often results in regression of breast tissue within 3 months.
A 58-year-old postmenopausal female presents with a recent onset of painless vaginal bleeding. Her last menses occurred 8 years ago and she has had no bleeding until now. She reports that her Papanicolaou smears have always been normal, with the last one obtained a year ago. A pelvic examination today is normal.
Which one of the following management options is the preferred next diagnostic step? (check one)
Colposcopy with endocervical curettage
Transvaginal ultrasonography
Saline infusion sonohysterography
Hysteroscopy
Transvaginal ultrasonography
Transvaginal ultrasonography is the preferred initial test for a patient with painless postmenopausal bleeding, although endometrial biopsy is an option if transvaginal ultrasonography is not available. Transvaginal ultrasonography showing an endometrial thickness <3–4 mm would essentially rule out endometrial carcinoma (SOR C). An endometrial biopsy is invasive and has low sensitivity for focal lesions. Saline infusion hysterography should be considered if the endometrial thickness is greater than the threshold, or if an adequate measurement cannot be obtained by ultrasonography. If hysterography shows a global process, then a histologic diagnosis can usually be obtained with an endometrial biopsy, but if a focal lesion is present hysteroscopy should be considered as the next diagnostic step. Colposcopy is not indicated given the patient’s normal Papanicolaou smear.
A 39-year-old female presents with lower abdominal/pelvic pain. On examination, with the patient in a supine position, you palpate the tender area of her lower abdomen. When you have her raise both legs off the table while you palpate the abdomen, her pain intensifies.
Which one of the following is the most likely diagnosis? (check one)
Appendicitis
A hematoma within the abdominal wall musculature
Diverticulitis
Pelvic inflammatory disease
An ovarian cyst
A hematoma within the abdominal wall musculature
A reduction of the pain caused by abdominal palpation when the abdominal muscles are tightened is known as Carnett’s sign. If the cause of the pain is visceral, the taut abdominal muscles may protect the locus of pain. In contrast, intensification of pain with this maneuver points to a source of pain within the abdominal wall itself.
A 50-year-old female reports vaginal dryness, burning, and pain with penetration during sexual intercourse. On examination she is noted to have pale, dry vaginal epithelium that is smooth and shiny with loss of most rugation.
Which one of the following treatments is most likely to be effective for her sexual dysfunction? (check one)
Cognitive-behavioral therapy
Vaginal estrogen
Testosterone therapy
Bupropion (Wellbutrin)
Sildenafil (Viagra)
Vaginal estrogen
This patient has genitourinary syndrome of menopause (formerly termed vulvovaginal atrophy) based on her symptoms and examination. Estrogen therapy is highly effective for dyspareunia related to genitourinary syndrome of menopause, with the vaginal route preferred over systemic therapy if vaginal dryness is the primary concern. Bupropion and sildenafil may benefit women with sexual dysfunction induced by antidepressant medications. Data on the benefit of testosterone therapy is limited and inconsistent and lacks long-term information about safety. Cognitive-behavioral therapy has been shown to effectively treat low sexual desire, but does not affect the physiologic changes associated with genitourinary syndrome of menopause.
Which one of the following is the basis for the most effective method of natural family planning? (check one)
Calendar calculation
Basal body temperature charting
Cervical mucus monitoring
Monitoring for urine estrogen metabolites
Coitus interruptus (withdrawal)
Cervical mucus monitoring
Natural family planning (NFP) is a potentially effective method for contraception and for determining the time of ovulation for purposes of conception. While the contraceptive effectiveness of the different NFP methods varies significantly, the success rates for typical use are as high as 92%–98% (SOR B). Monitoring the presence and consistency of cervical mucus production allows for the determination of both the beginning and end of a woman’s most fertile period. Some NFP methods use cervical mucus secretion as the sole basis for determining fertility. The symptothermal method also incorporates calendar calculations, basal body temperature measurement, and ovulation-related symptoms as a complement to the cervical mucus component. The Marquette Model incorporates cervical mucus and basal body temperature charting with electronic monitoring of urine estrogen and LH metabolites to provide additional information to determine when ovulation has occurred.
A 32-year-old white primigravida has a stillbirth at 33 weeks gestation. Which one of the following is the most likely cause? (check one)
Infection
Placental disease
A fetal structural disorder
A hypertensive disorder
Placental disease
Stillbirth is defined as fetal death occurring at or after 20 weeks gestation, and affects approximately 1 in 160 pregnancies in the United States. A large study of stillbirths from 2006 to 2008 tried to establish a cause in 663 cases, and a probable or possible cause was identified in approximately 75% of these. While there were some significant ethnic differences, placental abnormalities and obstetric complications were the largest category of causes in white women, and this was even more true after 32 weeks gestation. Other important causes included infection and fetal defects. More than one cause was found in one-third of cases.
A 24-year-od nulligravida comes to your office for contraception counseling. She has a seizure disorder that is well controlled on carbamazepine (Tegretol). She is a nonsmoker and has no other medical problems or complaints. She is currently in a relationship and does not want to get pregnant in the next several years.
Which one of the following contraceptive options would be the most appropriate? (check one)
Progestin-only pills
Combined oral contraceptives
The etonogestrel/ethinyl estradiol vaginal ring (NuvaRing
The norelgestromin/ethinyl estradiol contraceptive patch (Ortho Evra)
A levonorgestrel intrauterine device (Mirena)
A levonorgestrel intrauterine device (Mirena)
Certain antiepileptic drugs induce hepatic metabolism of estrogen and progestin (carbamazepine, oxcarbazepine, phenobarbital, phenytoin, and topiramate). This can potentially lead to failure of any contraceptive that contains estrogen and progestin. Progestin-only pills are most effective in women who are exclusively breastfeeding. They are not as effective in pregnancy prevention in other circumstances. Another effective option for women taking antiepileptic medications would be an intrauterine device. The levonorgestrel (progestin only) IUD and copper IUD are acceptable choices even for a nulligravida. The single-rod implantable progestin system also would be an acceptable choice for this patient.
A 46-year-old African-American female sees you because of a history of excessive uterine bleeding and irregularity in her menstrual cycle. She has three children and had a tubal ligation after her last delivery. A pelvic examination does not reveal any pathology to explain her symptoms. Further laboratory evaluation indicates that she is mildly anemic. You perform an endometrial biopsy in the office that confirms your suspicion of endometrial hyperplasia without atypia.
Which one of the following is the treatment of choice for this patient?
(check one)
Elective hysterectomy
Hysteroscopic endometrial laser ablation
High-dose oral estrogen supplementation
Antifibrinolytic therapy
Progestational drugs
Progestational drugs
Medical therapy with progestational drugs is the treatment of choice for menorrhagia due to endometrial hyperplasia without atypia. Progestins convert the proliferative endometrium to a secretory one, causing withdrawal bleeding and the regression of hyperplasia. The most commonly used form is cyclic oral medroxyprogesterone, given 14 days per month, but implanted intrauterine levonorgestrel is the most effective (SOR A) and also provides contraception.
High-dose estrogen supplementation would further stimulate the endometrium. Estrogen is useful in cases where minimal estrogen stimulation is associated with breakthrough bleeding. The anti-fibrinolytic agent tranexamic acid prevents the activation of plasminogen and is given at the beginning of the cycle to decrease bleeding. Side effects and cost limit this treatment option, however. It may be most useful in women with bleeding disorders or with contraindications to hormonal therapy.
NSAIDs, which decrease prostaglandin levels, reduce menstrual bleeding but not as effectively as progestins. While mefenamic acid is marketed for menstrual cramps and bleeding, all NSAIDs have a similar effect in this regard.
If medical management fails, hysteroscopic endometrial ablation is an option for reducing uterine bleeding but is considered permanent and obviously will impair fertility. Hysterectomy is reserved for severe and chronic bleeding that is not relieved by other measures.
A 27-year-old gravida 2 para 2 presents because of tenderness in her left lower breast, which she first noticed this morning. Three weeks ago she vaginally delivered an 8 lb 1 oz infant. She breastfed her first child for 10 months and initiated breastfeeding after this delivery without difficulty. Currently she is feeding her infant on cue about every 2–4 hours. On examination she has 4 cm of focal tenderness at 6 o’clock on the breast with no skin erythema. Her vital signs include a temperature of 37.0°C (98.6°F), a pulse rate of 84 beats/min, and a blood pressure of 118/72 mm Hg.
Which one of the following would be the most appropriate next step? (check one)
A trial of conservative management of breastfeeding on cue and analgesics
Expressing breast milk by hand every 1½ hours to keep the breast emptied
Expressing breast milk with a breast pump hourly to keep the breast emptied
Amoxicillin/clavulanate (Augmentin), 875/125 mg twice daily for 5 days; plus pumping and discarding the breast milk
Cephalexin, 500 mg four times daily for 7 days; plus pumping and discarding the breast milk
A trial of conservative management of breastfeeding on cue and analgesics
This patient has mild lactational mastitis with no systemic symptoms. Antibiotics are unnecessary and the condition may be managed conservatively with rest, cold compresses, over-the-counter acetaminophen or NSAIDs, and close monitoring for systemic symptoms. The patient should continue on-demand breastfeeding (physiologic feeding). Efforts to keep the breast drained of milk, such as frequent breast pumping or decreased feeding intervals, increase milk production, which may increase breast pain or abscess formation. If the patient develops fever or chills, antibiotics covering Staphylococcus and Streptococcus should be started. The standard treatment is dicloxacillin, 500 mg four times daily for 10–14 days. Other commonly used antibiotics are amoxicillin/clavulanate, 875/125 mg twice daily, or cephalexin, 500 mg four times daily, for 10–14 days. Breast milk does not need to be discarded when the patient is taking these antibiotics.
A 44-year-old female with localized breast cancer is receiving counseling about adjuvant long-term therapy. Which one of the following is more likely to occur with an aromatase inhibitor such as letrozole (Femara) than with tamoxifen (Soltamox)?
(check one)
Endometrial cancer
Venous thromboembolism
Inflammatory arthritis
Myalgias
Myalgias
Myalgias and noninflammatory arthralgias are more likely with aromatase inhibitors. Venous thromboembolism rarely occurs with these drugs. Endometrial cancer may occur with long-term use of tamoxifen.
Which class of medication is first-line therapy for uncomplicated depression during pregnancy?
(check one)
Monoamine oxidase inhibitors (MAOIs)
SSRIs
SNRIs
Stimulants
Tricyclic antidepressants
SSRIs
The treatment of depression in pregnancy is determined by the severity of the symptoms and any past history of treatment response. For women who have a new onset of mild or moderate depression, it may be best to start with nonpharmacologic treatments such as supportive psychotherapy or cognitive-behavioral therapy. These interventions may improve the depression enough that the patient will not need medications. However, in situations where pharmacologic treatment is clearly indicated, SSRIs are thought to have the best safety profile. Fluoxetine, sertraline, and citalopram have extensive data to support their safety in pregnancy and should be considered first line. Paroxetine is the one SSRI that is thought to carry an increased risk of congenital malformations with first-trimester exposure and should be avoided.
Tricyclic antidepressants are class D in pregnancy. SNRIs do not have as much safety data as SSRIs to support their use in pregnancy and would be considered a second-line choice. MAOIs are known teratogens and should be avoided in pregnancy. Stimulants are not first-line agents and should be avoided in pregnancy.
Which one of the following is NOT a risk factor for stillbirth? (check one)
Smoking
Advanced maternal age
Congential anomalies
Vigorous exercise
BMI >30 kg/m2
Vigorous exercise
Risk factors for stillbirth include advanced maternal age, smoking >½ pack of cigarettes a day, congenital
anomalies, and a BMI >30 kg/m2. Excessive exercise has not been shown to increase the risk for
stillbirth.
A morbidly obese 68-year-old male complains of breast enlargement. He has not noticed any pain or discomfort from this problem. His past medical history is negative except for type 2 diabetes mellitus and hypertension. His medications include metformin (Glucophage), 1000 mg twice daily; lisinopril (Prinivil, Zestril), 20 mg daily; and aspirin, 81 mg daily. His family history is negative for breast cancer. A physical examination is negative except for a BMI of 45 kg/m2 and symmetric bilateral adipose tissue in the breast region on inspection and palpation. There is no glandular tissue on careful palpation of the area beneath the areolae and nipples. No nodules or axillary nodes are detected. There is no nipple retraction or discharge, and no skin changes.
Which one of the following is the most likely cause of this problem?
(check one)
Fat necrosis
Gynecomastia
Pseudogynecomastia
Breast cancer
Mastitis
Pseudogynecomastia
This patient most likely has pseudogynecomastia due to increases in subareolar fat secondary to his obesity. This is based upon clinical findings of symmetric adipose tissue in the breast region bilaterally and a lack of firm, palpable glandular tissue in the nipple and areolar region. In gynecomastia, there is palpable, firm glandular tissue in a concentric mass around the nipple-areola complex. Hard, immobile masses, masses associated with skin changes, nipple retraction, nipple discharge, or enlarged lymph nodes would suggest possible malignancy. Fat necrosis would involve a history of breast region trauma and would generally be asymmetric. Mastitis would cause clinical signs of infection.
You respond to a code blue in the obstetrics department. The patient is a 19-year-old primigravida at 35 weeks gestation, hospitalized with severe preeclampsia. A nurse anesthetist has placed an oral airway and is administering 100% oxygen to the apneic patient. She reports no difficulty ventilating the patient with a bag and valve, and no gagging with oral airway insertion. The patient’s blood pressure is 100/60 mm Hg and her pulse rate is 70 beats/min and regular. Her pupils are equal and sluggishly reactive, and she is flaccid and areflexic. The patient had been treated with a magnesium sulfate infusion and a recent bolus of labetalol.
Which one of the following medications should you administer initially?
(check one)
Calcium gluconate
Fosphenytoin
Labetalol
Lorazepam (Ativan)
Dopamine
Calcium gluconate
During the treatment of severe preeclampsia with intravenous magnesium, the occurrence of apnea and areflexia is most consistent with magnesium toxicity. In addition to hemodynamic support, calcium infusion is recommended as an antidote. Calcium chloride can be used if a central line has been established. Calcium gluconate would be safer with a peripheral intravenous site.
Lorazepam, phenytoin, and fosphenytoin are less useful in preventing eclamptic seizures than magnesium. Labetalol is not indicated given the patient’s current blood pressure level. Dopamine, a pressor agent, is not indicated in this scenario, and could aggravate the patient’s preeclampsia.
A 30-year-old female complains of dysmenorrhea, pelvic pain, and dyspareunia. Which one of
the following would be appropriate to detect endometriosis?
(check one)
A CA-125 assay
Transvaginal ultrasonography
CT of the pelvis
MRI of the pelvis
Colonoscopy
Transvaginal ultrasonography
Endometriosis is caused by menstrual tissue in the pelvic peritoneal cavity. Infertility, dysmenorrhea, and
dyspareunia with postcoital bleeding are common. Although laparoscopy with histology is the definitive
test, transvaginal ultrasonography is the noninvasive test of choice. CA-125 will often be elevated but is
nonspecific. CT and MRI also have low specificity, and colonoscopy is of no value in the evaluation of
endometriosis.
In women with polycystic ovary syndrome, the risk is increased the most for carcinoma of the?

Endometrium
Several disorders that are common in women with polycystic ovary syndrome are associated with an increased risk for endometrial carcinoma, including obesity, hyperinsulinemia, diabetes mellitus, anovulatory cycles, and high androgen levels.
A 25-year-old primigravida asks about pain management during labor. You inform her that use of regional analgesia during labor?
(check one)
Increases the likelihood of cesarean delivery
Increases the risk for instrument-assisted vaginal delivery
Provides less pain relief than opioid analgesia
Lowers 1-minute Apgar scores
Increases the risk for instrument-assisted vaginal delivery
Regional analgesia in laboring patients increases the risk of vacuum-or forceps-assisted delivery (relative risk = 1.42; 95% confidence interval, 1.28–1.57; 23 trials; n = 735). Multiple randomized, controlled trials have compared regional analgesia with no analgesia. In a meta-analysis, no statistically significant impact was found on the risk of cesarean delivery, maternal satisfaction with pain relief, long-term backache, or immediate effect on neonatal status as determined by Apgar scores. Regional analgesia provides better pain relief than opioid analgesia.
Which one of the following conditions presents an unacceptable health risk for combined oral contraceptive use?
(check one)
Migraine with aura
Endometrial hyperplasia
Breastfeeding 1–6 months post partum
Chronic hepatitis
Previous laparoscopic banding weight-loss surgery
Migraine with aura
The World Health Organization (WHO) publishes the medical eligibility criteria for contraceptive use as a guideline for the appropriate use of contraceptives. There are four categories that define the appropriateness of contraceptive use in women with certain medical problems:
Category 1: A condition for which there is no restriction for the use of the contraceptive method.
Category 2: A condition for which the advantages of using the method generally outweigh the theoretical or proven risks.
Category 3: A condition for which the theoretical risk or proven risks usually outweigh the advantages of using the method.
Category 4: A condition that represents an unacceptable health risk if the contraceptive method is used.
A history of migraine with aura is classified as category 4 for oral contraceptives. Women with a history of migraines are 2–4 times as likely to have a stroke compared to women without migraines, and women who have an aura associated with their migraines are at even higher risk. Migraine without aura is classified as category 2 in women younger than 35 and category 3 in women 35 or older. Nonmigrainous headaches are category 1, as is chronic hepatitis C.
Combined oral contraceptive use does not appear to increase the rate or severity of cirrhotic fibrosis and there is no increased risk for hepatocellular carcinoma. Combined oral contraceptives are not recommended for use in women with acute hepatitis C. Breastfeeding is considered category 2 by the CDC and category 3 by WHO. There is conflicting evidence about the effects on the volume of breast milk in women who are on combined oral contraceptives, but the concerns are mainly during the first month of the postpartum period. There have not been any demonstrated adverse health effects in infants exposed to combined oral contraceptives through breast milk. Laparoscopic banding weight-loss surgery is category 1 for combined oral contraceptive use. Evidence shows no significant decrease in the effectiveness of oral contraceptives in women who have had this surgery. Combined oral contraceptive use in patients with endometrial hyperplasia is category 1. Combined oral contraceptives have been used to decrease the risk for endometrial cancer.
