This preterm labor quiz helps you recognize early signs, consider common risks, and decide when to call your provider. For more practice, try our go into labor quiz and a broader labor and delivery quiz, or review related warning signs in a preeclampsia symptoms quiz.

What is the clinical definition of preterm labour?
Uterine contractions causing cervical dilation and effacement before 37 completed weeks
Onset of labour after 37 weeks of gestation
Abdominal cramping before 20 weeks gestation
Regular contractions without cervical change between 20 and 37 weeks
Preterm labour is defined as the onset of regular uterine contractions associated with cervical change (dilation and effacement) before 37 completed weeks of gestation. This distinguishes it from false labour and from term labour. Cervical change is key to the diagnosis rather than just experiencing contractions.
Which of the following is a common symptom of preterm labour?
Decreased fetal movements
Persistent headache
Regular uterine contractions and low backache
Painless vaginal bleeding
Regular uterine contractions accompanied by a dull, constant low backache are among the most common early symptoms of preterm labour. These contractions may be painless or mild at first but can become more frequent and painful. Recognizing these signs early allows for timely evaluation and intervention.
What does the obstetric shorthand G2P0101 indicate?
Gravida 2, para 0, one abortion, zero living children
Gravida 2, para 1 (one term birth)
Gravida 2, para 0, one preterm birth, zero abortions, one living child
Gravida 2, para 1, zero preterm, zero abortions, one living child
Obstetric notation G2P0101 denotes two pregnancies (G2), zero term births, one preterm birth, zero abortions, and one living child. This expanded TPAL (Term, Preterm, Abortions, Living) system provides more detail than the simple parity count. It helps clinicians understand past obstetric history at a glance.
Which laboratory test is most commonly used to predict the risk of preterm birth?
Maternal serum alpha-fetoprotein
Amniotic fluid interleukin-6
Fetal fibronectin assay
Placental growth factor level
The fetal fibronectin (fFN) assay measures the presence of a fetal protein in cervicovaginal secretions and is the best-validated laboratory predictor of preterm delivery within two weeks. A negative fFN test has a high negative predictive value for excluding imminent preterm birth. Positive results warrant closer monitoring and consideration of interventions.
Which intervention is given to accelerate fetal lung maturity in preterm labour?
Nifedipine
Betamethasone
Magnesium sulfate
Indomethacin
Antenatal corticosteroids such as betamethasone are administered to pregnant women at risk of preterm delivery to enhance fetal lung maturation and reduce neonatal respiratory distress syndrome. They also decrease intraventricular hemorrhage and necrotizing enterocolitis risk. Corticosteroid therapy is recommended between 24 and 34 weeks when preterm birth is anticipated.
Which tocolytic agent is considered first-line for delaying preterm labour?
Magnesium sulfate
Indomethacin
Nifedipine
Terbutaline
Nifedipine, a calcium channel blocker, is widely considered first-line for tocolysis due to its efficacy and safety profile. It inhibits calcium influx in myometrial cells, reducing uterine contractions. Side effects are generally mild compared to beta-agonists or NSAIDs.
A transvaginal ultrasound shows a cervical length below which threshold is strongly predictive of preterm birth?
Less than 40 millimeters
More than 50 millimeters
More than 35 millimeters
Less than 25 millimeters
A cervical length measured by transvaginal ultrasound of less than 25 mm before 24 weeks is strongly associated with increased risk of spontaneous preterm birth. This finding can guide interventions such as vaginal progesterone or cerclage placement. Serial measurements help assess dynamic changes.
At what gestational age is magnesium sulfate recommended for fetal neuroprotection in preterm labour?
Before 36 weeks
Before 28 weeks
Before 32 weeks
Before 34 weeks
Magnesium sulfate administered to women at risk of imminent preterm birth before 32 weeks is recommended for fetal neuroprotection, reducing the risk of cerebral palsy in survivors. The neuroprotective benefit is greatest when given within 24 hours of delivery. Extended use beyond 48 hours is generally not advised.

Study Outcomes

  1. Understand Preterm Labour Fundamentals -

    You'll grasp the core definition of preterm labour and the key risk factors that predispose women to early birth.

  2. Identify Preterm Labour Symptoms -

    You'll learn to recognize common warning signs, from uterine contractions to cervical changes, so you can spot early indicators.

  3. Analyze g2p0101 Case Scenarios -

    You'll examine practical g2p0101 patient examples to assess individual risk and differentiate normal from pathological findings.

  4. Apply Diagnostic Criteria -

    You'll use established criteria and assessment tools to determine whether a patient meets the thresholds for preterm labour evaluation.

  5. Evaluate Intervention Strategies -

    You'll review evidence-based treatments, including cervical cerclage and tocolytic therapies, to decide when each intervention is appropriate.

  6. Interpret Quiz Feedback -

    You'll interpret your quiz results to pinpoint knowledge gaps and reinforce strengths in preterm labour risk assessment.

Cheat Sheet

  1. Contraction Patterns -

    Monitor uterine activity by timing contractions: if you experience ≥4 contractions in 20 minutes or ≥8 in 60 minutes, suspect preterm labour (ACOG 2022). Use a simple count-and-timer approach - start a stopwatch at the first tighten and stop at the next, then tally over 20 minutes to decide if you need further assessment in this preterm labour quiz.

  2. Cervical Assessment -

    Evaluate cervical dilation and effacement via transvaginal ultrasound or digital exam; ≥2 cm dilation or ≥80% effacement before 37 weeks signals active preterm labour (WHO guidelines). Remember the mnemonic "3 Cs": Contractions, Cervix change, Countdown to term for your preterm labor symptoms quiz.

  3. Risk Factor Review (g2p0101 Focus) -

    Identify high-risk profiles such as g2p0101 with a history of preterm birth, uterine anomalies, or short cervical length (<25 mm) on ultrasound (RCOG 2021). A quick checklist - prior PTB, infection history, multiple gestation - helps boost confidence in your "am I in preterm labour" risk assessment.

  4. Cerclage and Other Interventions -

    Understand cerclage placement indications: McDonald or Shirodkar sutures at 12 - 14 weeks for cervical incompetence significantly reduce preterm labour risk (Cochrane Review 2020). Pair this with progesterone therapy and a tocolytic plan for a multi-pronged strategy in your preterm labour quiz prep.

  5. Biomarker & Length Screening -

    Combine fetal fibronectin testing (fFN) with cervical length measurement: a negative fFN plus >30 mm cervical length yields a 99% negative predictive value for delivery within two weeks (Johns Hopkins, 2019). This duo is your go-to formula for acing any preterm labor risk assessment challenge.
