- Clinical Skills: Skills like assessing labour progress and managing perineal tears are vital in maternal care.
- Score Booster: A strong performance in this section can significantly improve your overall exam score.
At logyanlo.in, our Day 25 Practice Test is crafted to help you master these concepts and feel confident heading into the 2025 exams.
Key Concepts in Obstetrics and Midwifery for Your Exam Prep
Let us explore the core topics of Obstetrics and Midwifery that you need to know for your AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM exams. We will focus on nursing responsibilities and exam-relevant points.
Fetal Development
Fetal development refers to the growth and maturation of the fetus from conception to birth, spanning 40 weeks of gestation.
Stages:
First Trimester (Weeks 1–12):
- Major organ systems form (organogenesis).
- Heartbeat begins by week 5; detectable by ultrasound by week 6.
Second Trimester (Weeks 13–26):
- Fetus grows rapidly, movements (quickening) felt by the mother (around 18–20 weeks).
- Lanugo (fine hair) and vernix caseosa (protective coating) develop.
Third Trimester (Weeks 27–40):
- Fetus gains weight, lungs mature (surfactant production by week 34).
- Fetus assumes head-down position for birth.
Nursing Responsibilities:
- Monitor fetal growth via fundal height measurement (matches gestational age in centimeters, e.g., 30 cm at 30 weeks).
- Assess for risk factors, like maternal smoking, which can lead to intrauterine growth restriction (IUGR).
- Educate mothers on nutrition, like increasing iron and folic acid intake to support fetal development.
Exams often test your knowledge of fetal development milestones, like the onset of fetal movements in the second trimester.
Fetal Circulation
Fetal circulation is unique, designed to bypass the lungs and liver, which are not fully functional until after birth.
Key Features:
- Umbilical Cord: Contains two arteries (carry deoxygenated blood) and one vein (carries oxygenated blood from the placenta).
Shunts:
- Ductus Venosus: Shunts blood from the umbilical vein to the inferior vena cava, bypassing the liver.
- Foramen Ovale: Shunts blood from the right atrium to the left atrium, bypassing the lungs.
- Ductus Arteriosus: Shunts blood from the pulmonary artery to the aorta, bypassing the lungs.
- Oxygenation: The placenta oxygenates blood, as fetal lungs are filled with fluid and not used for breathing.
Post-Birth Changes:
At birth, the shunts close: foramen ovale becomes fossa ovalis, ductus arteriosus becomes ligamentum arteriosum, ductus venosus becomes ligamentum venosum.
Lungs inflate, and pulmonary circulation begins.
Nursing Responsibilities:
- Monitor fetal heart rate (normal: 110–160 beats/min) using a Doppler or cardiotocography (CTG).
- Assess for signs of fetal distress, like decelerations in heart rate, which may indicate umbilical cord compression.
- Educate mothers on avoiding smoking, as it reduces oxygen delivery to the fetus via the placenta.
Exams often test your understanding of fetal shunts, like the role of the ductus arteriosus in bypassing the lungs.
Labour
Labour is the process of childbirth, involving uterine contractions, cervical dilation, and delivery of the baby and placenta.
Signs of Labour:
- Regular, painful uterine contractions (every 5–10 minutes).
- Cervical dilation and effacement (thinning).
- Rupture of membranes (water breaking).
- Bloody show (mucous plug discharge with blood).
Stages of Labour:
1- First Stage: Onset of contractions to full cervical dilation (10 cm).
- Latent Phase: 0–3 cm dilation, contractions irregular.
- Active Phase: 4–7 cm dilation, contractions stronger.
- Transition Phase: 8–10 cm dilation, intense contractions.
2- Second Stage: Full dilation to delivery of the baby.
3- Third Stage: Delivery of the baby to delivery of the placenta.
4- Fourth Stage: First 1–2 hours postpartum, monitoring for complications.
Nursing Responsibilities:
- Monitor contraction frequency, duration, and intensity (normal: 3–5 contractions every 10 minutes in active labour).
- Assess cervical dilation via vaginal examination (with consent).
- Provide comfort measures, like encouraging walking or breathing techniques during labour.
Exams often test your knowledge of labour stages, like identifying the active phase by 4–7 cm dilation.
Normal Labour
Normal labour (also called spontaneous vaginal delivery) occurs without complications, typically at term (37–42 weeks).
Characteristics:
- Presentation: Cephalic (head-first), anterior position.
- Progress: Cervical dilation at 1–2 cm/hour in active phase for first-time mothers (primigravida).
Duration:
- First stage: 6–12 hours (primigravida), 4–8 hours (multigravida).
- Second stage: 30 minutes to 2 hours.
- Third stage: 5–30 minutes.
Nursing Responsibilities:
- Monitor fetal heart rate every 15–30 minutes in active labour (normal: 110–160 beats/min).
- Encourage pushing during the second stage, using techniques like the Valsalva maneuver.
- Support the perineum during delivery to reduce the risk of tearing.
- Inspect the placenta after delivery for completeness to prevent postpartum hemorrhage.
Exams often test your understanding of normal labour progress, like the expected duration of the second stage.
Maternal Pelvis
The maternal pelvis plays a key role in childbirth, providing a pathway for the fetus.
Types of Pelvis:
- Gynecoid: Most common, round shape, ideal for vaginal delivery.
- Android: Heart-shaped, narrower, more common in males, may complicate delivery.
- Anthropoid: Oval, longer front-to-back, usually allows vaginal delivery.
- Platypelloid: Flat, wider side-to-side, may complicate delivery.
Pelvic Diameters:
- Inlet: Widest at the transverse diameter (13 cm).
- Midpelvis: Narrowest at the ischial spines.
- Outlet: Widest at the anteroposterior diameter (11 cm).
Nursing Responsibilities:
- Assess pelvic adequacy via clinical pelvimetry (if trained), checking for narrow diameters.
- Monitor labour progress, as a contracted pelvis may lead to prolonged labour or cephalopelvic disproportion (CPD).
- Educate mothers on positions like squatting, which can increase pelvic outlet diameter during delivery.
Exams often test your knowledge of pelvic types, like identifying the gynecoid pelvis as ideal for delivery.
Induction of Labour
Induction of labour is the artificial initiation of labour before spontaneous onset, often for medical reasons.
Indications:
- Post-term pregnancy (>42 weeks).
- Maternal conditions (e.g., preeclampsia, diabetes).
- Fetal conditions (e.g., growth restriction, oligohydramnios).
Methods:
Pharmacological:
- Oxytocin (Pitocin): IV drip to stimulate contractions.
- Prostaglandins (e.g., Misoprostol): Soften and dilate the cervix.
Mechanical:
- Amniotomy: Artificial rupture of membranes (ARM) to release prostaglandins.
- Foley catheter: Mechanically dilates the cervix.
- Natural: Nipple stimulation to release endogenous oxytocin.
Nursing Responsibilities:
- Assess Bishop score (cervical readiness, score >8 indicates favorable induction).
- Monitor fetal heart rate and uterine contractions during induction to detect hyperstimulation.
- Educate mothers on the procedure, like explaining that contractions may feel stronger with oxytocin.
Exams often test your understanding of induction methods, like the use of oxytocin to stimulate contractions.
Episiotomy
Episiotomy is a surgical incision made in the perineum to enlarge the vaginal opening during delivery.
Types:
- Midline: Straight incision toward the anus, easier to repair but higher risk of extension.
- Mediolateral: Diagonal incision, lower risk of extension but harder to repair.
Indications:
- To prevent uncontrolled perineal tears.
- To facilitate delivery in cases of fetal distress or shoulder dystocia.
- To assist with instrumental delivery (e.g., forceps).
Nursing Responsibilities:
- Administer local anesthesia (e.g., lidocaine) before the incision, as per protocol.
- Monitor for complications post-episiotomy, like infection or hematoma at the site.
- Educate mothers on perineal care, like using sitz baths to promote healing and reduce pain.
Exams often test your knowledge of episiotomy types, like the advantage of a mediolateral incision in reducing tear extension.
Perineal Tear and Lacerations
Perineal tears and lacerations occur during vaginal delivery due to stretching of the perineum.
Degrees:
- First Degree: Involves only the vaginal mucosa and perineal skin.
- Second Degree: Extends to the perineal muscles but not the anal sphincter.
- Third Degree: Involves the anal sphincter.
- Fourth Degree: Extends through the anal sphincter into the rectal mucosa.
Management:
- First and Second Degree: Suture repair under local anesthesia.
- Third and Fourth Degree: Surgical repair in an operating room, often with antibiotics to prevent infection.
- Pain Relief: Ice packs for the first 24 hours, then warm sitz baths.
Nursing Responsibilities:
- Assess the degree of tear during postpartum examination, checking for rectal involvement.
- Monitor for signs of infection, like foul-smelling discharge or fever.
- Educate mothers on perineal hygiene, like cleaning front-to-back to prevent infection.
Exams often test your understanding of perineal tear degrees, like identifying a fourth-degree tear by rectal involvement.
