Study Notes

APGAR Score Assessment

The APGAR score is a standardized assessment tool for newborns, performed at 1 minute and 5 minutes after birth, with a score out of 10.
A higher APGAR score indicates better health.
It measures five criteria:
- Respirations
- Pulse
- Activity
- Grimace
- Appearance

Goals of Fetal Heart Rate Monitoring

The primary goal is to monitor fetal well-being by assessing fetal oxygenation levels.
Effective monitoring minimizes unnecessary interventions while promoting family-centered care.
Good fetal oxygenation is essential for placental health.

Methods of Fetal Heart Rate Monitoring

External Monitoring
- Uses continuous electronic fetal monitoring (CEFM) via ultrasound.
- Intermittent monitoring can be done using a Doppler device or wireless systems.
- Contractions are measured using a tocodynamometer (toco transducer).
Internal Monitoring
- Involves placing a fetal scalp electrode (FSE) on the fetus's presenting part and an intrauterine pressure catheter (IUPC) to measure uterine contractions.
- Requires ruptured membranes for placement.
- Contraindications include chorioamnionitis, Group B Streptococcus positivity, genital herpes, and placenta previa.

Fetal Heart Rate Characteristics

Normal Fetal Heart Rate Baseline
- Ranges from 110 to 160 bpm over a 10-minute window.
- Changes in baseline can be categorized as periodic (related to contractions) or episodic (independent of contractions).
Abnormal Fetal Heart Rate Baselines
- Tachycardia: A baseline heart rate greater than 160 bpm for 10 minutes or more.
- Bradycardia: A baseline heart rate less than 110 bpm for 10 minutes or more.
- Indeterminate: Situations where the FHR baseline cannot be accurately assessed.

Fetal Heart Rate Variability and Decelerations

FHR Variability
- Refers to fluctuations in the FHR from the baseline, excluding accelerations and decelerations.
- Types of variability:
  - Absent
  - Minimal
  - Moderate
  - Marked
Types of FHR Decelerations
- Early Decelerations: Occur in relation to uterine contractions, generally reassuring and not concerning.
- Variable Decelerations: Rapid decrease to nadir in less than 30 seconds, indicating cord compression.
- Late Decelerations: Occur after the peak of contractions, indicating utero-placental insufficiency.

FHR Tracing Categories and Uterine Activity Assessment

FHR Tracing Categories
- Category I: Normal tracing indicating a well-oxygenated fetus.
- Category II: Indeterminate tracing that requires further evaluation.
- Category III: Abnormal tracing requiring expedited delivery.
Assessing Uterine Activity
- Assessed through monitoring contractions, which can be done externally or internally.
- The frequency, duration, and intensity of contractions are critical for evaluating labor progress and fetal well-being.

Uterine Activity Assessment: Key Components

Frequency: Measured in contractions per 10 minutes.
Intensity: Assessed through palpation, categorized as mild, moderate, or strong.
Duration: The length of time each contraction lasts.

Palpation Techniques

Mild Contraction: Feels like the tip of the nose.
Moderate Contraction: Feels like the chin.
Strong Contraction: Feels like the forehead.

Uterine Tone and Contraction Patterns

Resting Tone: A resting period of at least 1 minute between contractions.
Tachysystole: 6 or more contractions in 10 minutes.

Monitoring Uterine Contractions

Tocometer: An external monitor that measures abdominal pressure.
IUPC (Intrauterine Pressure Catheter): An internal monitor that measures the strength of contractions.

Measurement of Uterine Activity

MVUs (Montevideo Units): Calculated by subtracting baseline uterine pressure from peak contraction pressure over a 10-minute window.

Intrauterine Resuscitation Strategies

Strategies for Improving Uteroplacental Perfusion
- Position Change: Left lateral position enhances blood flow to the placenta.
- IV Bolus: Administering IV fluids can improve maternal oxygenation.
- Oxygen Therapy: Administering oxygen via face mask helps improve fetal oxygenation.
Additional Resuscitation Techniques
- Sterile Vaginal Exam (SVE): Used to assess labor progress and perform scalp stimulation.
- Amnioinfusion: Administering fluid into the amniotic cavity.
- Adjusting Uterine Activity: Monitoring for tachysystole and adjusting medications.

Uterine Dystocia and Nursing Interventions

Understanding Uterine Dystocia
- Abnormal labor characterized by lack of progressive cervical dilation or fetal descent.
- Risk Factors: Maternal exhaustion and the effects of epidural anesthesia.
- Types: Fetal dystocia, pelvic dystocia, and uterine dystocia.
Nursing Interventions for Hypertonic Contractions
- Promote rest, administer pain medications, encourage relaxation techniques, and ensure hydration.
Nursing Interventions for Hypotonic Contractions
- Assess uterine activity, stimulate contractions through ambulation, hydration, and potentially augment labor with oxytocin.

Labor Arrest Disorders and Fetal Presentations

Differences in Labor Arrest Disorders
- First Stage Arrest Disorder: Defined as failure of cervical dilation.
- Second Stage Arrest Disorder: Defined as failure of fetal head descent.
Malpresentations Leading to Dystocia
- Occiput Posterior
- Face Presentation
- Breech Presentations

Induction of Labor and Bishop Score

Methods of Labor Induction
- Induction of Labor (IOL): Deliberate stimulation of labor onset for vaginal birth.
- Cervical Preparation: Involves mechanical and pharmacological methods.
- Oxytocin Administration: Used to stimulate contractions and labor progression.
Understanding the Bishop Score
- A scoring system used to assess the readiness of the cervix for labor.
- A score greater than 8 indicates a high likelihood of successful vaginal delivery with induction.
- A score less than 6 suggests a higher risk of cesarean delivery.
- A score between 6 and 8 is considered favorable for induction.

Labor Augmentation: Indications and Contraindications

Labor augmentation refers to the stimulation of contractions when labor is not progressing adequately.
Indications include fewer than 3 contractions in 10 minutes or contractions with an intensity less than 25 mmHg above baseline.
Contraindications include conditions like placenta previa, umbilical cord presentation, prior classical uterine incision, active genital herpes, pelvic deformities, and invasive cervical cancer.

Complications During Labor

Risks Associated with Shoulder Dystocia
- Severe maternal complications, including 4th-degree perineal lacerations and maternal symphyseal separation.
- Peripheral neuropathy may occur.
- Sphincter injuries and infections are also potential risks.
- The McRoberts maneuver is a common intervention.
Fetal Risks in Shoulder Dystocia
- Compression of the fetal neck by the maternal pelvis.
- The 'turtle sign' is a key indicator, where the fetal head retracts against the perineum after delivery.

Umbilical Cord Prolapse and Its Implications

Understanding Umbilical Cord Prolapse
- Occurs when the cord is partially or completely occluded, leading to rapid deterioration in fetal perfusion and oxygenation.
- Can cause fetal hypoxia, which may result in long-term disabilities or even death.
Risk factors include malpresentation of the fetus, fetal anomalies, intrauterine growth restriction.

Cesarean Birth: Nursing Roles and Responsibilities

Nursing Role in Unscheduled Cesarean Birth
- Nurses must stabilize both the patient and fetus, adhering to the 30-minute 'decision to incision' rule.
- Key nursing actions include completing admission assessments, ensuring lab tests are done, starting IV fluids, and preparing the patient for surgery.
- Emotional support for the patient and family is crucial.
Intraoperative Complications and Management
- Potential intraoperative complications include hemorrhage, trauma to surrounding organs, maternal respiratory depression, and hypotension.
Postoperative Care Following Cesarean Birth
- Postoperative care includes monitoring vital signs, assessing blood loss, and evaluating the fundus and lochia.
- Nurses should assess the abdominal dressing for signs of infection and manage pain effectively.
- Encouraging early ambulation and lung auscultation is essential.

Physiologic Care of the Neonate

Nursing Actions During Newborn Transition
- Key nursing actions include maintaining body heat, ensuring respiratory function, and minimizing infection risks.
- Supporting parents in providing appropriate nutrition and hydration is vital.

Neonatal Care

Neutral Thermal Environment
- Crucial for maintaining a neonate's body temperature with minimal metabolic changes and oxygen consumption.
- Cold stress involves excessive heat loss leading to hypothermia in newborns.
- Brown adipose tissue plays a significant role in thermoregulation.
Hypoglycemia in Neonates
- Hypoglycemia is a common condition during the transitional period after birth.
- Signs and symptoms of hypoglycemia include jitteriness, lethargy, and poor feeding.
- Blood glucose levels should be monitored to ensure they remain within a safe range.
- Maintaining a neutral thermal environment is essential to prevent further metabolic stress on the neonate.
- Establishing early feeding is critical.
Vitamin K Injection
- Newborns are at risk for vitamin K deficiency due to low levels at birth.
- Vitamin K is essential for proper blood clotting.
- The injection is given prophylactically to prevent bleeding disorders in neonates.

Newborn Stool and Urine Output Changes

Gastric capacity in neonates starts at approximately 5-10 mL and increases to about 60 mL by day 7.
Newborns typically excrete 15-60 mL/kg of urine per day initially.
Stool changes from meconium to transitional stool and finally to yellow, soft, and watery stools.

Newborn Assessment and Reflexes

Weight Loss in Infants
- It is normal for neonates to lose 5-10% of their birth weight during the first week.
- This weight loss is typically a result of fluid shifts and should stabilize as feeding is established.
Assessment for Congenital Hip Dislocation
- The Barlow and Ortolani maneuvers are key assessments.
- Unequal gluteal folds or positive results from these maneuvers may indicate hip dislocation.
Newborn Reflexes
- Moro, Startle, Tonic Neck, Rooting, Sucking, Palmar Grasp, Plantar Grasp, Babinski, and Stepping reflexes are assessed.
- Each reflex serves as an indicator of neurological development and should be symmetrical and appropriate for the infant's age.

Jaundice and Vaccinations

Physiologic vs.Pathologic Jaundice
- Physiologic jaundice appears after the first 24 hours of life.
- Pathologic jaundice occurs within the first 24 hours.
Common Newborn Vaccinations
- The Hepatitis B vaccine is administered in three doses.
- Erythromycin is used as prophylaxis against gonococcal and chlamydial eye infections in newborns.

Postpartum Care

Postpartum Assessment
- The postpartum assessment includes monitoring vital signs, particularly for hypotension.
- The BUBBLE-LE acronym is used to assess Breasts, Uterus, Bladder, Bowel, Lochia, Episiotomy, Lower extremities, and Emotions.
- A perineal assessment using the REEDA scale (Redness, Edema, Ecchymosis, Discharge, Approximation).
Gastrointestinal Changes Postpartum
- The gastrointestinal system typically returns to normal function within two weeks postpartum.
- Common issues include constipation and hemorrhoids.
Uterine Involution
- The process by which the uterus returns to its pre-pregnancy size and shape.
- Assessment involves palpating the fundus for position, tone, and midline alignment.
Lochia Types
- Lochia is the vaginal discharge following childbirth, consisting of blood and tissue.
- Types of lochia include Rubra, Serosa, and Alba.

Postpartum Complications

Urinary System Considerations
- Postpartum women may experience bladder distention and incomplete emptying.
- Encourage early voiding, assess intake and output, and educate patients about potential urinary issues.
Risk Factors for Postpartum Hemorrhage
- Postpartum hemorrhage (PPH) is defined as blood loss exceeding 500cc for vaginal births and 1000cc for cesarean sections.
- The greatest risk for PPH occurs within the first hour after delivery.
Postpartum Hemorrhage (PPH)
- Types of Postpartum Hemorrhage:
  - Primary PPH: Occurs within the first 24 hours after birth.
  - Secondary PPH: Occurs from day 1 to 6 weeks postpartum.
- Risk Factors for PPH:
  - Neonatal macrosomia: Larger babies can lead to increased uterine stretching and complications.
  - Placenta previa/accreta: Abnormal placental attachment can cause significant bleeding.

Multiple Gestation

Increased risk of postpartum hemorrhage due to larger uterine size and potential complications during delivery.
Previous cesarean section or uterine surgery can increase bleeding risk.
Scarring from previous surgeries can affect uterine tone.

Postpartum Hemorrhage

Four main causes: Tone (uterine atony), Tissue (retained placental fragments), Trauma (lacerations), Thrombin (coagulation disorders).
Uterine Atony: Characterized by a soft, boggy fundus indicating a lack of uterine contraction, leading to bleeding.
Retained Placental Fragments: Common cause of secondary postpartum hemorrhage. May require surgical intervention if not expelled naturally.

Postpartum Depression vs. Baby Blues

Postpartum Blues: Symptoms resolve within 2 weeks without intervention. Mothers can care for themselves and their babies.
Postpartum Depression (PPD): Symptoms persist beyond 2 weeks, requiring psychiatric intervention. May impair the ability to care for self and baby.

High-Risk Neonatal Nursing Care

Factors Influencing Infant Health

Longer gestation typically correlates with better health outcomes.
Low birth weight is associated with higher morbidity and mortality rates.

Respiratory Distress Syndrome (RDS)

A life-threatening condition due to underdeveloped alveoli and insufficient surfactant.
Symptoms: Tachypnea, gray or dusky skin, lethargy, and hypotonia.

Patent Ductus Arteriosus (PDA)

A condition where the ductus arteriosus fails to close after birth, leading to abnormal blood flow.
Normally closes within hours but can take up to 96 hours post-birth.
Symptoms: Tachycardia, tachypnea, recurrent apnea, and bounding pulses.

Meconium Aspiration Syndrome

Occurs when meconium enters the lungs, causing respiratory failure.
Increased risk in postmature newborns (after 41 weeks).
Nursing actions: Assess for respiratory distress and administer oxygen as needed.
