What is the most common cause of vaginal bleeding in the first trimester of pregnancy?
Threatened miscarriage
Ectopic pregnancy
Subchorionic hematoma
Implantation bleeding
Threatened miscarriage is the most frequent cause of first?trimester bleeding and presents with vaginal bleeding and a closed cervical os. While subchorionic hematoma and ectopic pregnancy can also cause bleeding, they are less common. Early evaluation with ultrasound and serial beta-hCG levels helps distinguish these conditions. ACOG FAQ
Which condition most commonly presents with painless, bright red vaginal bleeding in the third trimester?
Placenta previa
Placental abruption
Uterine rupture
Preterm labor
Placenta previa typically causes painless, bright red bleeding in the third trimester because the placenta overlies the cervical os. In contrast, placental abruption usually presents with painful bleeding and uterine tenderness. Accurate diagnosis requires ultrasound before any digital exam. Wikipedia: Placenta previa
What is the first step in evaluating a pregnant patient with vaginal bleeding?
Assess maternal vital signs and hemodynamic status
Obtain a transvaginal ultrasound
Draw complete blood count and coagulation studies
Administer uterotonics
Initial management of any bleeding patient focuses on maternal stabilization: airway, breathing, and circulation. Vital signs and hemodynamic assessment guide urgency and need for resuscitation. Further diagnostics (ultrasound, labs) follow stabilization. ACOG Committee Opinion
A Rh-negative woman experiences first-trimester bleeding at 14 weeks. What is the appropriate management?
Administer Rh immunoglobulin (Rho(D) immune globulin)
Perform amniocentesis
Transfuse crossmatched Rh-positive blood
No intervention needed
Any Rh-negative woman with potential fetomaternal hemorrhage should receive Rho(D) immune globulin to prevent alloimmunization. This holds true even in early pregnancy bleeding. Amniocentesis is not indicated for bleeding alone. ACOG FAQ
Which diagnostic modality is preferred for suspected vasa previa?
Transvaginal ultrasound with color Doppler
Magnetic resonance imaging (MRI)
Speculum examination
Abdominal X-ray
Transvaginal ultrasound with color Doppler is the gold standard to visualize fetal vessels overlying the cervix in vasa previa. It is noninvasive and has high sensitivity and specificity. MRI is rarely needed when ultrasound is diagnostic. Wikipedia: Vasa previa
Which risk factor is most strongly associated with placental abruption?
Maternal hypertension
Polyhydramnios
Advanced maternal age
Multiparity
Chronic hypertension and preeclampsia are the strongest risk factors for placental abruption due to vascular damage and ischemia. Trauma and cocaine use are also notable but less common overall. Polyhydramnios and multiparity have weaker associations. CDC Overview
The Kleihauer-Betke test is used to:
Quantify fetal red blood cells in maternal circulation
Measure maternal hemoglobin
Assess coagulopathy
Evaluate placental perfusion
The Kleihauer-Betke test estimates the volume of fetal blood transferred into the maternal bloodstream, guiding the dose of Rho(D) immune globulin. It is not used to measure maternal hemoglobin or coagulation status. Wikipedia: Kleihauer–Betke test
A woman at 10 weeks with minimal bleeding and closed cervical os is diagnosed with a nonviable intrauterine pregnancy. What management is most appropriate?
Expectant management
Immediate dilation and curettage
Methotrexate therapy
Blood transfusion
In a stable patient with a nonviable pregnancy and minimal bleeding, expectant management is often appropriate, allowing spontaneous passage of products of conception. Surgical or medical management is reserved for heavy bleeding or patient preference. ACOG Committee Opinion
A 32-week pregnant patient presents with sudden painful vaginal bleeding, uterine tenderness, and a firm, board-like abdomen. What is the most likely diagnosis?
Placental abruption
Placenta previa
Vasa previa
Uterine rupture
Placental abruption classically presents with painful bleeding, uterine tenderness, and a hypertonic, board-like uterus due to retroplacental clot formation. Placenta previa is painless. Uterine rupture may also cause pain but typically involves loss of fetal station and abnormal fetal heart tracing. ACOG FAQ
Which class of hemorrhagic shock corresponds to a blood loss of 15–30% and tachycardia with minimal hypotension?
Class II
Class I
Class III
Class IV
Class II hemorrhagic shock involves 15–30% blood volume loss, characterized by tachycardia (100–120 bpm), mild hypotension, and delayed capillary refill. Class I is <15%; Class III is 30–40%; Class IV is >40%. Wikipedia: Hemorrhagic shock
During initial fluid resuscitation for a bleeding pregnant patient, which fluid is recommended first-line?
Isotonic crystalloid solution
Packed red blood cells
Colloid solution
Hypertonic saline
Isotonic crystalloid (e.g., normal saline or lactated Ringer’s) is the first-line fluid for initial volume resuscitation in hemorrhagic shock. Blood products are added once crossmatching is available or if significant blood loss is ongoing. NCBI: Fluid Resuscitation
Which type of placenta previa completely covers the internal cervical os on ultrasound?
Complete previa
Marginal previa
Low-lying placenta
Partial previa
Complete placenta previa describes a placenta that entirely covers the internal cervical os. Partial previa covers part of the os; marginal reaches within 2 cm; low-lying lies near but does not reach the os. Precise classification guides delivery planning. Wikipedia: Placenta previa
On ultrasound, a crescent-shaped hypoechoic area between the chorion and uterine wall suggests:
Subchorionic hematoma
Placental abruption
Amniotic band
Hydatidiform mole
A subchorionic hematoma appears as a crescent-shaped, hypoechoic or anechoic area under the fetal membranes on ultrasound. It is associated with first-trimester bleeding and increased risk of miscarriage. Management is usually expectant if bleeding is minimal. ACOG FAQ
Which clinical sign is most specific for uterine rupture during labor?
Sudden loss of fetal station with abnormal fetal heart trace
Onset of painless bleeding
Gradual abdominal distension
Decreased uterine resting tone
Uterine rupture often presents with sudden loss of fetal station, abnormal fetal heart monitoring (bradycardia or decelerations), and cessation of contractions. Pain may also be severe. Painless bleeding suggests previa, not rupture. Wikipedia: Uterine rupture
Which laboratory finding is an early indicator of DIC in placental abruption?
Fibrinogen level below 200 mg/dL
Platelet count above 400,000/µL
Elevated hemoglobin
Normal prothrombin time
A fibrinogen level <200 mg/dL is an early and sensitive marker of DIC in obstetric hemorrhage, especially placental abruption. Fibrinogen levels correlate with bleeding severity and outcomes. Platelet counts and PT change later. NCBI PMC
In a patient with diagnosed vasa previa and intact membranes at 34 weeks, the recommended delivery plan is:
Elective cesarean delivery at 35–36 weeks
Induction of labor at term
Expectant management until spontaneous labor
Vaginal delivery with forceps
Elective cesarean delivery at 35–36 weeks is recommended for vasa previa to prevent vessel rupture and fetal exsanguination. Labor or vaginal delivery is contraindicated due to high risk of vessel rupture. ACOG Consensus
Tocolytic therapy in the setting of placental abruption is:
Contraindicated because it may worsen bleeding
Recommended to delay delivery by at least 48 hours
First-line if contractions exceed five per hour
Allowed only with corticosteroids
Tocolysis is contraindicated in placental abruption because inhibiting contractions can increase retroplacental hemorrhage and maternal hemorrhagic risk. Management focuses on maternal stabilization and prompt delivery if indicated. ACOG Committee Opinion
In placental abruption, why is fibrinogen considered a key prognostic marker?
Low fibrinogen correlates with severity of bleeding and risk of DIC
High fibrinogen indicates amniotic fluid embolism
Fibrinogen levels rise in concealed hemorrhage
Normal fibrinogen rules out abruption
Fibrinogen is the first coagulation factor to fall in obstetric hemorrhage, and levels below 200 mg/dL indicate severe abruption and developing DIC. Early measurement aids risk stratification and management. Elevated levels are not characteristic. NCBI PMC
What blood product transfusion ratio is recommended in massive obstetric hemorrhage?
1:1:1 ratio of RBCs to FFP to platelets
2:1:1 ratio of RBCs to FFP to platelets
1:2:1 ratio of RBCs to FFP to platelets
Only packed RBCs until hemodynamic stability
A balanced 1:1:1 transfusion ratio of red blood cells, fresh frozen plasma, and platelets is recommended to mitigate coagulopathy in massive obstetric hemorrhage. This approach mimics whole blood components and improves outcomes. WHO Guidelines
Which factor most significantly increases the risk of uterine rupture during trial of labor after cesarean (TOLAC)?
A prior classical (vertical) uterine incision
Prior low-transverse incision
Use of epidural anesthesia
Advanced maternal age
A prior classical (vertical) uterine incision carries the highest risk of rupture during TOLAC due to the orientation of the scar. Low-transverse scars have a much lower rupture rate. Epidural anesthesia and age are not major risk factors. ACOG FAQ
Which placental invasion disorder describes penetration of villi into the myometrium but not through the serosa?
Placenta increta
Placenta accreta
Placenta percreta
Placenta succenturiata
Placenta increta involves invasion of chorionic villi into the myometrium without penetrating the uterine serosa. Placenta accreta attaches superficially without myometrial invasion; percreta invades through the serosa. Wikipedia: Placenta accreta spectrum
A stable patient at 36 weeks with low-lying placenta and minimal bleeding should be managed with:
Hospitalization with pelvic rest and observation
Immediate cesarean delivery
High-dose tocolytics
Magnesium sulfate infusion
Patients with low-lying placenta and minimal bleeding at term can be managed expectantly with hospitalization, pelvic rest, and serial ultrasounds. Immediate cesarean is reserved for ongoing hemorrhage or complete previa. Tocolytics are contraindicated. ACOG Committee Opinion
Why is administration of Rho(D) immunoglobulin ideally performed within 72 hours of a bleeding event?
To prevent maternal alloimmunization by clearing fetal Rh-positive cells
To enhance fetal hemoglobin production
To treat maternal anemia
To induce uterine contractions
Administering Rho(D) immunoglobulin within 72 hours of fetomaternal hemorrhage clears Rh-positive fetal red cells before maternal sensitization. Delayed administration reduces efficacy and increases alloimmunization risk. It does not treat anemia or affect contractions. ACOG FAQ
How does vasa previa lead to rapid fetal exsanguination if undiagnosed during labor?
Fetal vessels traverse the membranes unprotected by Wharton’s jelly, rupturing over the cervix
Placental cotyledons detach prematurely
Uterine arteries constrict abruptly
Amniotic fluid volume decreases rapidly
In vasa previa, fetal vessels run through the membranes near the cervical os without the cushioning of Wharton’s jelly. When membranes rupture, these vessels tear, causing rapid fetal blood loss and exsanguination. Early diagnosis via ultrasound is critical. Wikipedia: Vasa previa
In a case of placenta percreta with bladder invasion discovered at cesarean delivery, the recommended management is:
Cesarean hysterectomy with urology team for bladder repair
Manual removal of placenta and uterine repair
Methotrexate injection into placental bed
Conservative leave-in-place management
Placenta percreta invading the bladder typically requires cesarean hysterectomy with a multidisciplinary team, including urology, to manage bladder repair and minimize hemorrhage. Conservative or medical management is not recommended when vital structures are involved. ACOG Committee Opinion

Cheat Sheet

  1. Ectopic Triad & Pregnancy of Unknown Location (PUL) -

    First trimester bleeding often stems from the classic ectopic triad: amenorrhea, abdominal pain, and vaginal bleeding. Recognize a pregnancy of unknown location (PUL) when serum β-hCG is below the discriminatory zone (1,500 - 2,000 mIU/mL per ACOG) and use the mnemonic "Disco Ball" (Discriminatory Zone ≈ 1500) to recall g4p0030 criteria quickly. (Source: ACOG Practice Bulletin)

  2. Shock Index for Hemodynamic Assessment -

    Calculate Shock Index (HR ÷ SBP) to detect early maternal compromise; a value >0.9 suggests significant hemorrhage even if vital signs look normal. This simple ratio helps you decide when to activate massive transfusion protocols and ensure rapid IV access. (Source: Royal College of Obstetricians & Gynaecologists)

  3. Point-of-Care Ultrasound (POCUS) Role -

    Transvaginal ultrasound is your frontline tool: identify an intrauterine gestational sac, subchorionic hematoma, or free fluid in the pelvis. Remember "Look for the sac first, then check for fluid" to differentiate miscarriage, implantation bleeding, and ruptured ectopic. (Source: UpToDate)

  4. Rh(D) Immunoprophylaxis Protocol -

    Any Rh(D)-negative patient with vaginal bleeding requires 300 µg of anti-D immunoglobulin within 72 hours to prevent alloimmunization. Use the "3-2-1" rule: 300 µg for standard bleed, 200 µg covers 20 mL fetal blood, given in 1 shot. (Source: ACOG Committee Opinion)

  5. Methotrexate Criteria & Mnemonic -

    For stable, unruptured ectopic pregnancies <3.5 cm without fetal cardiac activity and β-hCG <5,000 mIU/mL, single-dose methotrexate is first-line. Recall "Size, Stable, Serum, Sac" (4 S's) when evaluating candidates and track β-hCG on days 4 and 7 for a ≥15% drop. (Source: WHO Medical Eligibility Criteria)
