High BhCg in second trimester indicator of molar pregnancy. C. High BhCg in second trimester is the most sensitive marker of Down syndrome. D. High Bhcg can cause elevation of TRH which causes hyperthyroidism Correct Answer: C Explanation: - Hyperthyroidism in pregnancy is caused by direct stimulation of the maternal thyroid gland by elevated levels of human chorionic gonadotropin (hCG), which can be associated with a transient lowering in serum TRH and TSH levels - Second-trimester (QUADRUPLE test) total levels of hCG, dimeric inhibin A (DIA), AFP, unconjugated estriol (uE3) are the most sensitive test (its QUADRUPLE test not BhCG alone) So, for our CASES: ( In the first recall) (1) - D is the correct answer because high B-HCG causes reciprocal suppression of TSH and TRH. - Why not C? it’s true that high BHCG is a sensitive marker for down syndrome (but not ALONE!! It’s a quadruple test) (In the second recall) (2) - D is wrong! High bhCG never causes elevation of TRH levels!! (it causes suppression of TRH and TSH due to the direct stimulation of the thyroid gland” hyperthyroidism”) - So, in that case C is the only correct answer so I would go with C 18 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics What would you expect in pregnancy?

A. Induce labor B. C-section C. CTG Daily Correct Answer: B Explanation: - Non-reassuring CTG means CTG Category 2 or 3. But, as long as he didn’t specify the category, then anticipate the worst and manage accordingly. Let’s Exclude!! - Induce labor à we cant induce labor (oxytocin) if her CTG is non-reassuring, as the management of non-reassuring CTG in to stop oxytocin - C-section à answered by exclusion and it’s the difintive management of CTG category3 - CTG daily à You cannot manage a non-reassuring CTG with CTG daily Pregnant 42 weeks, in labor 7 cm dilated, meconium staining liquor, regular and strong contractions, CTG showing fetal heart rate of 100? A. C-section B. Augment labor Correct Answer: A Explanation: (According to Uptodate) Management of Meconium stained amniotic fluid: - Induction of labor and continuous fetal monitoring. (expectant management in case of reassuring CTG is acceptable also) - Evaluation and interventions are implemented in cases with abnormal tracings indicative of fetal stress to reduce the likelihood of perinatal asphyxia. We agree that FHR monitoring identifies signs of hypoxemia and allows the caregivers to initiate prompt interventions in order to reduce the risk of MAS. Let’s Exclude!! - C-section à By exclusion, as our patient has CTG category2 (bradycardia), which is managed by in utero resuscitation measure e.g. lateral positioning of the mother, O2, IV fluid, stop oxytocin, administer toocolytic drugs. If in utero resuscitation measures are not in the choices, i would go with C-section - Augment labor à Management of CTG category 2 is to stop oxytocin as mentioned above. Also, she has regular and strong contractions no need to augment labor 85 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics Pregnant, primigravida in labor for couple of hours, 6cm dilated, 80% effacement, 0 station, was managed with oxytocin and ruptured membrane for 20 hours.

Urgent C-section Correct Answer: A Another recall 35-Year-old pregnant lady with fetal death and DIC, her cervix is 4cm dilated, (her vitals shows hypotension), what is the management? A. Induction of labor B. Urgent C-section Correct Answer: B Explanation: (According to Uptodate) DIC in Pregnancy - In Hemodynamically unstable mother OR fetal distress OR contraindication to vaginal delivery Cesarean delivery is indicated Why? if the mother is hemodynamically unstable, Vaginal delivery is not the safest maternal option if hemodynamic instability from ongoing brisk uterine bleeding persists despite vigorous transfusion of blood and blood products. In these cases, cesarean delivery is indicated to save the mother's life - In Hemodynamically stable mother with dead or nonviable fetus Induction of Labor is indicated Why? avoiding cesarean delivery because of the risk of uncontrollable hemorrhage from surgical incisions and lacerations. Delivery is initiated, as removal of the products of conception removes the trigger for DIC - In Hemodynamically stable mother with a viable fetus and reassuring fetal status In those rare cases in which the mother with acute disseminated intravascular coagulation (DIC) is responding appropriately to resuscitation with blood products and 90 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics the fetal heart rate (FHR) tracing is normal, there is no compelling need for immediate delivery (induction of labor, cesarean birth). Instead, the clinical focus is on reversing or eliminating the cause of DIC and reducing the risk of bleeding and thrombosis. After this has been achieved, decision-making regarding expectant management or delivery depends on the gestational age and expected course of the underlying cause of DIC. Pregnant with DIC and CTG normal no deceleration and good contract what to do? A. Augment labor B. C-section C. Reassure Correct Answer: C Explanation: (According to Uptodate) DIC in Pregnancy - In Hemodynamically stable mother with a viable fetus and reassuring fetal status In those rare cases in which the mother with acute disseminated intravascular coagulation (DIC) is responding appropriately to resuscitation with blood products and the fetal heart rate (FHR) tracing is normal, there is no compelling need for immediate delivery (induction of labor, cesarean birth). Instead, the clinical focus is on reversing or eliminating the cause of DIC and reducing the risk of bleeding and thrombosis. After this has been achieved, decision-making regarding expectant management or delivery depends on the gestational age and expected course of the underlying cause of DIC. Pregnant lady, diabetic, 38 weeks in active labor and having DKA profile and fetus in distress (CTG that is suggested of bradycardia) what to do? A. Change the mother’s position of labor B. Stop and do C-section Correct Answer: A Explanation: (According to Uptodate and ACOG) Diabetic KetoAcidosis in Pregnancy DKA - Clinical presentation Includes abdominal pain, nausea, vomiting, and altered sensorium. - Laboratory findings: Includes hyperglycemia (usually >250 mg/dL [13.9 mmol/L]), acidemia (arterial pH 12 mEq/L), ketonemia, low serum bicarbonate (4 mEq/L), and renal dysfunction - Continuous fetal heart rate monitoring Minimal or absent variability and absent accelerations, as well as repetitive decelerations. These abnormalities usually resolve with resolution of DKA - Management: Intravenous insulin, appropriate volume replacement, correction of electrolyte abnormalities (including potassium, phosphate, and magnesium), monitoring acidosis, and a search for precipitating causes. 91 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics Emergency delivery before maternal stabilization should be avoided because it increases the risk of maternal morbidity and mortality and may result in delivery of a hypoxic, acidotic preterm infant. Note: - If IV insulin and hydration in the choices I would choose it. - If not? in utero resuscitation measure is also correct. Urine Dipstick pic with: +2 protein, very high glucose, +ve ketones in pregnant lady 39 weeks with effacement 90% and cervix dilation 2 cm, what is your most appropriate action? A. Induction of labor (IOL) B. C-section C. Expectant management Correct Answer: A Explanation: (According to ACOG ) When to deliver in case of Diabetes Mellitus? - At 39+0 to 39+6 weeks if well-controlled glucose levels and no vascular disease; - At 36+0 to 38+6 weeks if poorly controlled glucose levels or vascular disease (even earlier if severity of complications warrants earlier delivery) - Expectant management beyond 40+0 weeks is not recommended. Note: - Delivery before maternal stabilization should be avoided! - For this patient the correct answer is to manage the DKA (by insulin and hydration) and stabilize the mother! à Then induction of labor after correction of her status. - If IV insulin and hydration in the choices I would choose it. If not? IOL While the obstetrician closes the caesarean incision, patient developed bleeding. What is the cause? A. Liver haemangioma B. Spleen aneurysm C. Perforated peptic ulcer D. Mesenteric ischemia Correct Answer: B Explanation: Splenic artery aneurysms - Are the third most common true aneurysm occurring in the abdomen after aortic and iliac artery aneurysms. Splenic artery aneurysms are more common in women (female:male = 4:1) and are commonly associated with conditions of increased flow, such as pregnancy (particularly multiparity, because the risk increases with increasing parity) 92 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics - Approximately, 95% of SAA rupture occurs during pregnancy, most commonly during the third trimester. - If a woman has an existing SAA, the risk of rupture during pregnancy is 20–50%. - Though the rupture of a SAA during pregnancy is a rare event, it carries a high risk of maternal and fetal mortality. The mortality in the general population when a SAA ruptures is 25%. In pregnant women, this rate increases to a 75% maternal mortality rate and a 95% fetal mortality rate - Obstetricians and other emergency providers should consider a ruptured SAA in any pregnant woman who presents with an acute surgical abdomen. - In the rare minority of women of childbearing age who are discovered to have an asymptomatic SAA prior to rupture, a proactive approach to management should be undertaken due to the high risk of rupture in pregnancy. Liver hemangioma - May increase in size during pregnancy or with estrogen therapy. But, risk of lesion rupture is similar for pregnant and nonpregnant women Elective Cesarean section which week? A. 36 B. 37 C. 38 D. 39 Correct Answer: D Another recall Elective Cesarean section which week? A. 36-37 B. 38 C. 39 D. Full term Correct Answer: D Explanation: (According to Uptodate) - When a primary cesarean delivery is indicated for maternal or fetal reasons, but preterm birth is not indicated, there is consensus that planned term cesarean delivery should be scheduled in the 39th or 40th week of gestation - Full term = between 39 and 40 weeks Female pregnant, polyhydramnios had ruptured membrane, on CTG persistent fetal bradycardia? A. Rapid fetal descend B. Cord prolapse C. Anomaly 93 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics Correct Answer: B Explanation: (According to Uptodate) Risk factors for cord prolapse - Malpresentation (breech, transverse, oblique, or unstable lie) - Preterm gestational age - Low birth weight - Second twin - Low lying placentation - Pelvic deformities - Uterine malformations/tumors - External fetal anomalies - Multiparity - Polyhydramnios - Long umbilical cord - Unengaged presenting part - Prolonged labor - Atypical placental cord insertions (velamentous and marginal) Obstetric interventions account for approximately 50 percent of cases of cord prolapse, include: - Iatrogenic rupture of membranes, especially with an unengaged presenting part - Cervical ripening with a balloon catheter - Induction of labor - Application of an internal scalp electrode - Insertion of an intrauterine pressure catheter - Manual rotation of the fetal head - Amnioinfusion - External cephalic version - Internal podalic version - Application of forceps or vacuum Note: Polyhydramnios + Ruptured membrane + Bradycardia = Cord prolapse! Signs of fetal distress in CTG: A. Less contractions B. Early deceleration C.

A. Spontaneous separation B. Fundus pressure C. Manual removal Correct Answer: C Explanation: (According to NICE guidelines and ACOG) Method of placental removal Remove the placenta in caesarean birth using controlled cord traction and not manual removal to reduce the risk of endometritis. Two methods are frequently used to deliver the placenta at C-section: - Cord traction - Manual removal The best method to deliver the placenta during C/section is by cord traction followed by fundal message and pressure (active management of the 3rd stage to prevent PPH) Note: 95 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics If cord traction in the choices it’s the correct answer, if not I would go with manual removal Pregnant G3P2, 37 weeks with a history of C-section due to non-reassuring CTG.

A pregnant woman with twins, first twin is breech, second twin is cephalic, what is the management? A. Spontaneous vaginal delivery B. ECV then vaginal delivery C. C-section Correct Answer: C Explanation: (According to Uptodate) We suggest cesarean birth when the first twin is in a noncephalic presentation, which occurs in approximately 20 percent of twin gestations. Unbooked female came to the ED with labor, after investigation she has 100,000 colony bacteria of streptococcus and she has asthma with using salbutamol, what do you wanna give her now and after deliver? A. Ampicillin B. Oxytocin Correct Answer: A Explanation: (According to ACOG) - If GBS bacteriuria at any colony count is detected during pregnancy, the woman is at increased risk of GBS colonization during labor. A notation should be made in her medical record, she should be made aware of her GBS status, and antibiotic prophylaxis should be administered empirically during labor based on the risk factor of antepartum GBS bacteriuria - Intravenous penicillin remains the agent of choice for intrapartum prophylaxis, with intravenous ampicillin as an acceptable alternative. Pregnant at 39 weeks, now in labor during the delivery you noticed the amniotic fluid is mixed with dark black-green what is the cause of this color? A. Meconium aspiration syndrome B. Fetal distress C. Placenta abruptio D. Preterm labor Correct Answer: B Explanation: (According to Uptodate) 99 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics - Fetal stress may result in meconium passage, due to increased peristalsis and relaxation of the anal sphincter from increased vagal outflow associated with umbilical cord compression or increased sympathetic inflow during hypoxia - Fetal distress à causes meconium-stained amniotic fluid à which leads to meconium aspiration syndrome Female known to have DM, otherwise all normal, pregnant full term, during labor fetus had tachycardia, how to prevent this?

After delivery of the placenta by manual extraction contracting, Retroverted uterus happened but was back in place. Where was the placenta in the uterus? A. Anterior B. Posterior C. Lateral D. Fundus Correct Answer: D Explanation: Retroverted uterus means the uterus is tipped backwards (fundus is aimed toward the rectum) For example, if there’s fibroids in the fundus of the uterus it will cause retroversion of the uterus. Pregnant women during vaginal delivery, what can make her has fourth degree perineal tear? A. Unrestrained legs and squatting position B. Unrestrained legs and sitting on chair C. Restrained legs and use of forceps and other metallic instrument Correct Answer: C Explanation: (According to ACOG) The strongest risk factors for OASIS (Obstetric Anal Sphincter Injuries) including forceps delivery, vacuum- assisted delivery, midline episiotomy, and increased fetal birth weight. Midline episiotomy combined with forceps delivery substantially increases the risk of third-degree laceration and fourth-degree laceration. The risk of anal sphincter trauma with operative delivery and episiotomy is increased in primigravid women and multigravid women. 101 | P a g e Obstetrics and Gynecology: SMLE Questions and Answers Chapter 1: Obstetrics Which of the following positions of a patient in labor would most likely result in the development of a third or fourth-degree laceration?
