https://statstitch.etsy.com 1. Pregnancy Confirmation Signs Pregnancy is diagnosed through three categories of signs. Presumptive signs are subjective changes the patient experiences, like amenorrhea, nausea, and breast tenderness. Probable signs are objective findings by a provider, including a positive pregnancy test, Hegar’s sign (softening of the lower uterus), Goodell’s sign (cervical softening), and Chadwick’s sign (bluish-purple cervical discoloration). Positive signs offer 100% accuracy and include ultrasound verification, auscultating fetal heart tones, and provider-palpated fetal movement. 2. Critical Systemic Adaptations Cardiovascular: Blood volume surges by 30% to 50% to perfuse the enlarging uterus. Because plasma volume expands faster than red blood cell production, patients experience physiologic anemia of pregnancy. Pregnancy also induces a hypercoagulable state via increased fibrinogen to prevent hemorrhage, raising the risk of thrombosis. Supine hypotensive syndrome occurs when the gravid uterus compresses the inferior vena cava while lying flat, severely reducing cardiac output; this is reversed by resting in a left-lateral position. Gastrointestinal: Elevated progesterone causes widespread smooth muscle relaxation, leading to delayed gastric emptying, severe heartburn, and decreased peristalsis which results in constipation. Renal/Urinary: The kidneys must filter maternal and fetal waste, causing the glomerular filtration rate (GFR) to increase by up to 50%, which often requires therapeutic medication dosage adjustments. Respiratory: Oxygen consumption increases, and tidal volume expands by 30% to 40%. The growing uterus pushes the diaphragm upward, converting breathing from abdominal to thoracic. 3. Placental Endocrine Functions The placenta acts as a crucial endocrine organ: hCG: Maintains the maternal corpus luteum until the placenta takes over hormone synthesis. Progesterone: Known as the "hormone of pregnancy," it maintains the endometrium, prevents premature uterine contractions, and causes systemic smooth muscle relaxation. hPL (Human Placental Lactogen): Acts as a maternal insulin antagonist. It decreases maternal tissue sensitivity to insulin, ensuring a steady, constant supply of glucose crosses the placenta for the growing fetus. 4. Nutritional Requirements & Risks Weight Gain: Recommendations strictly depend on prepregnancy BMI. Patients with a Normal BMI (18.5–24.9) should gain 25 to 35 lbs. Underweight patients need 28–40 lbs, while obese patients should gain 11–20 lbs. Supplementation: Diets must be supplemented with iron for blood volume expansion and folic acid (400–800 mcg/day) to prevent fetal neural tube defects. Hazards: Patients must avoid high-mercury fish (swordfish, king mackerel) to protect fetal neurodevelopment. To prevent Listeriosis—which can cause miscarriage or neonatal sepsis—patients must strictly avoid unpasteurized dairy, raw sprouts, soft cheeses, and unheated deli meats. Pica: The compulsive consumption of nonfood items (e.g., dirt, ice, laundry starch) is closely associated with severe iron-deficiency anemia and poor weight gain.

https://statstitch.etsy.com Initial Assessment Folic acid (400-800 mcg/day) is vital to prevent neural tube defects. The initial prenatal visit establishes the Estimated Date of Delivery (EDD) using Naegele’s Rule: subtract 3 months from the first day of the last menstrual period (LMP), add 7 days, and add 1 year. Obstetric history uses the GTPAL acronym: Gravida (total pregnancies), Term (>38 weeks), Preterm (>20 but <37 weeks), Abortions (<20 weeks), and Living children. Physical assessment includes estimating pelvic adequacy by measuring the diagonal conjugate; a measurement ≥12.5 cm indicates the pelvic inlet is adequate. 2. Screenings & Diagnostic Tests Initial labs include blood typing, Rh factor, CBC, rubella, HIV, and STIs. Alpha-fetoprotein (MSAFP) screening occurs between 16 and 18 weeks; elevated levels indicate neural tube defects, while lower levels suggest Down syndrome. Invasive genetic diagnostic tests include Chorionic Villus Sampling (CVS) at 10-13 weeks and Amniocentesis at 15-20 weeks; both require administering anti-D immune globulin to Rh-negative patients. Gestational diabetes screening typically occurs between 24 and 28 weeks. Between 37 and 40 weeks, patients are screened for Group B Streptococcus. 3. Fetal Well-Being & Monitoring Fundal height corresponds to the weeks of gestation between 20 and 36 weeks (e.g., 24 cm equals 24 weeks). The normal fetal heart rate ranges from 110 to 160 bpm. Patients should perform daily fetal movement counts, as decreased movement strongly indicates fetal hypoxia. The Nonstress Test (NST) evaluates fetal heart rate accelerations; a "reactive" result shows at least two accelerations of ≥15 bpm lasting ≥15 seconds within 20 minutes. The Biophysical Profile (BPP) combines the NST with an ultrasound to evaluate fetal breathing, movement, tone, and amniotic fluid volume. A maximum score is 10; 8-10 is normal, while ≤6 is suspicious. 4. Discomforts & Danger Signs First-trimester discomforts include urinary frequency and nausea; nausea is mitigated by eating dry crackers before rising. Second-trimester issues include backache (relieved by pelvic tilt exercises) and leg cramps (relieved by dorsiflexing the foot). Third-trimester dependent edema is managed by elevating the legs. Patients must immediately report danger signs: early vaginal bleeding, severe vomiting, absent fetal movement, and symptoms of preeclampsia such as sudden facial edema, severe headaches, or visual changes. 5. Childbirth & Feeding Patients prepare for labor through education (e.g., Lamaze) focusing on breathing and relaxation. Breastfeeding is encouraged as it provides ideal nutrition, transfers antibodies, and promotes maternal uterine involution. For bottle-feeding, proper formula dilution is critical, and infants must be fed semi-upright to prevent choking and tooth decay

https://statstitch.etsy.com 1. Diagnosing and Dating Pregnancy Pregnancy manifestations are categorized into three groups. Presumptive signs are subjective client experiences, such as amenorrhea, fatigue, nausea, and quickening. Probable signs are objective provider findings, including abdominal enlargement, positive hCG tests, Hegar’s sign (softening of the lower uterus), and Chadwick’s sign (bluish cervical mucosa). Positive signs uniquely confirm pregnancy and include auscultated fetal heart sounds, ultrasound visualization, and provider-palpated fetal movement. To calculate the estimated delivery date, use Naegele’s rule: subtract 3 months from the first day of the last menstrual period, add 7 days, and adjust the year. Obstetric history is recorded using the GTPAL acronym: Gravidity (pregnancies), Term births (38+ weeks), Preterm births (20-37 weeks), Abortions (prior to viability), and Living children. 2. Key Physiological Adaptations Maternal cardiac output and blood volume increase by 30% to 50%, and the maternal heart rate increases by 10 to 15 beats per minute. A critical risk is supine hypotensive syndrome, where the heavy gravid uterus compresses the vena cava when the client lies flat, severely decreasing venous blood flow; the client should be placed in a left-lateral side-lying position to alleviate pressure. The expected fetal heart rate (FHR) baseline is 110 to 160 beats per minute. Skin changes include chloasma (facial pigmentation), linea nigra (dark abdominal line), and striae gravidarum (stretch marks). Psychosocially, first-trimester ambivalence (conflicting feelings) is a completely normal response that typically resolves before the third trimester. 3. Prenatal Care & Critical Screenings Between 18 and 30 weeks, fundal height in centimeters approximately equals the number of weeks of gestation. Fetal movement is usually felt between 16 and 20 weeks. Clients must monitor fetal kick counts; fewer than 3 movements per hour or a complete cessation for 12 hours requires immediate provider evaluation. Critical routine screenings include: Maternal serum alpha-fetoprotein (MSAFP): Drawn between 15-22 weeks to screen for neural tube defects (high levels) or Down syndrome (low levels). RhO(D) immune globulin: Administered IM at 28 weeks strictly for Rh-negative clients. Group B Streptococcus (GBS): Cultures are taken at 35 to 37.5 weeks of gestation. 1-hour glucose tolerance test: Screens for gestational diabetes; readings >140 mg/dL require a 3-hour diagnostic follow-up test. 4. Managing Common Discomforts To manage first-trimester nausea, clients should eat crackers or dry toast before rising in the morning and avoid an empty stomach. Urinary tract infections (UTIs) are common; clients should wipe from front to back, avoid bubble baths, and drink 8 glasses of water daily. Second and third-trimester backaches are relieved by performing pelvic tilt exercises and using proper body mechanics. For leg cramps, clients should extend the affected leg and dorsiflex the foot toward the head.

The Core of Labor Progression (The 5 Ps) A successful physiological labor relies on the "5 Ps": Passenger (fetus), Passage (maternal pelvis), Powers (contractions), Position (maternal), and Psyche (emotional state). For a vaginal birth, the fetus optimally descends in a longitudinal lie and cephalic (head-down) presentation, with a fully flexed neck to allow the smallest head diameter to pass through the maternal pelvis. Labor is driven by hormonal shifts, particularly an increase in estrogen and prostaglandins, which stimulate true labor contractions alongside oxytocin. True Labor vs. False Labor Unlike Braxton Hicks (false labor), true labor contractions increase in frequency, duration, and intensity, causing progressive cervical dilation and effacement. They often start in the lower back, feel like intense menstrual cramps, and do not stop with rest. The first stage of labor begins with these consistent contractions and ends when the cervix is fully dilated (10 cm) and 100% effaced (completely thinned). Key Clinical Assessments Nurses continuously evaluate uterine activity and fetal well-being. Contractions are assessed for frequency, intensity, duration, and resting tone. A healthy contraction pattern is five or fewer contractions in a 10-minute window; anything more is considered tachysystole and can cause severe fetal hypoxia by reducing blood flow to the placenta. To assess fetal positioning and find the best placement for the fetal monitor, nurses perform Leopold maneuvers, a four-step abdominal palpation technique. Vaginal exams are used to track dilation, effacement, and fetal station (the fetal presenting part's location relative to the maternal ischial spines). When amniotic membranes rupture, the fluid is tested with Nitrazine paper (which turns color due to amniotic fluid's 7.1-7.3 pH) and evaluated for meconium (a sign of fetal stress) or purulent drainage (a sign of infection). Fetal Heart Rate (FHR) Interpretation Monitoring FHR is crucial for detecting fetal hypoxia. The expected baseline FHR is 110 to 160 beats per minute with moderate variability, indicating normal acid-base status. FHR decelerations are categorized by their cause and dictate nursing responses: Early Decelerations: Mirror the contraction and indicate fetal head compression. This is an expected finding requiring no intervention. Variable Decelerations: Abrupt drops indicating umbilical cord compression. The primary intervention is maternal repositioning to a lateral position to relieve cord pressure. Late Decelerations: Gradual drops after the contraction peaks, signaling placental insufficiency. This requires immediate intervention. Prolonged Decelerations: Drops lasting 2 to 10 minutes, often tied to severe maternal hypotension or tachysystole. Intrauterine Resuscitation (Emergency Interventions) If a fetus displays an indeterminate (Category II) or abnormal (Category III) FHR pattern, nurses must rapidly initiate intrauterine resuscitation. These life-saving steps include: Maternal repositioning (lateral or knee-chest) to maximize uteroplacental blood flow. Increasing IV fluids to correct hypotension. Administering supplemental oxygen. Discontinuing uterotonics (like oxytocin) to stop contractions and promote uterine relaxation.

Fetal Heart Rate (FHR) Monitoring and Assessment A primary objective of labor management is tracking the FHR to detect changes early, ensure adequate fetal oxygenation, and prevent fetal injury. Initial continuous FHR assessment spans 10 to 20 minutes upon entry. Baseline variability is a key indicator and is categorized as absent, minimal, moderate (a normal fluctuation of 6 to 25 bpm), or marked. FHR patterns are evaluated in three tiers: Category I (Normal): Predictive of normal fetal acid-base status and requires no intervention. Category II (Indeterminate): Requires evaluation and continued surveillance. Category III (Abnormal): Predictive of abnormal acid-base status and requires immediate intervention. Essential interventions include notifying the health care provider, discontinuing oxytocin, repositioning the client (left or right lateral, knee-chest), administering oxygen via nonrebreather mask, increasing IV fluids, and preparing for an expeditious surgical birth if the pattern is not corrected within 30 minutes. Maternal Pain Management Pain during labor is a universal experience with highly variable intensity, and pain assessment is mandated for all clients. The modern nursing approach emphasizes the woman as an active participant in her pain management. Nonpharmacologic measures: Include continuous labor support, hydrotherapy, ambulation, position changes, acupressure, massage (effleurage), and patterned-paced breathing. Pharmacologic measures: Include systemic analgesia (IV opioids, ataractics, benzodiazepines) and regional/neuraxial anesthesia (epidural blocks, combined "walking" spinal-epidurals, and pudendal blocks for the second stage). General anesthesia is typically reserved for emergency cesarean births or when a woman has a contraindication to regional anesthesia. Stage-by-Stage Nursing Interventions First Stage: Initial contact often involves a phone assessment detailing the estimated date of birth, fetal movement, contraction characteristics, and membrane status. Admission requires a comprehensive health history and physical assessment, including vital signs, Leopold maneuvers, monitoring uterine contraction frequency/duration/intensity, checking cervical dilation and effacement, and determining fetal position. Routine lab studies (urinalysis, CBC) and necessary screenings (syphilis, HbsAg, GBS, HIV) are also collected. Second Stage (Birth): Care shifts to tracking the fetal response to labor and supporting involuntary bearing-down efforts. Nurses must encourage the mother not to push until she has a strong desire or until the descent and rotation of the fetal head are well advanced. Immediately following birth, newborn care involves drying, suctioning, clamping the umbilical cord, assigning the Apgar score, and identification. Third Stage (Placental Delivery): The nurse assesses for placental separation, administers ordered oxytocin, examines the placenta and fetal membranes, checks for perineal trauma, and documents birthing statistics. Fourth Stage (Recovery): Critical post-birth assessments demand frequent checks of vital signs, fundus firmness, lochia, perineal area, and bladder status/voiding. Promoting parent-newborn attachment, providing comfort measures, and initiating teaching are fundamental priorities during this final phase.

https://statstitch.etsy.com 1. Labor Mechanics and Dystocia Normal labor progression relies on the "Three Ps": Power (uterine contractions), Passenger (fetal size and presentation), and Passage (the maternal pelvis). Dystocia is an abnormal, slow progression of labor, broadly categorized into protraction (slower than normal) or arrest (complete cessation of progress) disorders. When labor stalls due to inadequate contractions, augmentation via amniotomy (rupturing the membranes) or intravenous oxytocin is used to stimulate progression. If the pelvis is inadequate or the fetus is severely malpositioned (e.g., breech or face presentation), a cesarean delivery is typically required to prevent injury. 2. Fetal Surveillance Electronic fetal monitoring evaluates fetal oxygenation and well-being. Fetal heart rate (FHR) tracings fall into three specific tiers: Category I (Normal): Baseline of 110-160 bpm, moderate variability, and no late or variable decelerations. Category II: Indeterminate tracings requiring continued surveillance. Category III (Abnormal): Absent variability coupled with recurrent late/variable decelerations or bradycardia. This indicates severe fetal hypoxia and often warrants immediate delivery. Deceleration patterns offer specific clues: early decelerations indicate benign fetal head compression, variable decelerations indicate umbilical cord compression, and late decelerations signal dangerous uteroplacental insufficiency. 3. Major Obstetric Emergencies Umbilical Cord Prolapse: The cord slips ahead of the fetus, causing severe cord compression. Providers must manually elevate the presenting part off the cord and immediately prepare for an emergency cesarean. Shoulder Dystocia: The fetal head delivers, but the anterior shoulder becomes trapped behind the pubic bone, often indicated by the "turtle sign". Crucial interventions include the McRoberts maneuver (hyperflexing maternal legs) and suprapubic pressure. Fundal pressure is strictly contraindicated as it worsens the impaction. Uterine Rupture & Placental Abruption: Rupture is a catastrophic tearing of the uterine wall, often at a prior cesarean scar. Abruption is the premature detachment of the placenta from the uterine wall. Both present with severe abdominal pain, fetal distress, and hemorrhage, requiring emergent surgery. Postpartum Hemorrhage (PPH): Defined as blood loss ≥1000 mL, primarily caused by the "4 Ts": Tone (uterine atony), Tissue (retained placenta), Trauma, and Thrombin (coagulopathy). First-line treatment focuses on fundal massage and uterotonic medications like oxytocin. 4. Preterm Labor Preterm labor involves regular contractions causing cervical change before 37 weeks' gestation. The primary goal is to delay delivery using tocolytics (such as magnesium sulfate or nifedipine) for at least 48 hours. This creates a critical window to administer corticosteroids (like betamethasone) to accelerate fetal lung maturity. 5. Early Pregnancy Complications Ectopic pregnancies occur when a fertilized egg implants outside the uterus, usually in the fallopian tube. They present with bleeding and abdominal pain, are diagnosed via ultrasound and rising hCG levels, and are treated medically with methotrexate or surgically. Spontaneous abortions (miscarriages) occur before 20 weeks and are managed expectantly, medically (e.g., misoprostol).

OB | Postpartum

IA

https://statstitch.etsy.com The puerperium, or postpartum period, spans the first 6 to 8 weeks after childbirth as the birthing parent's body undergoes dramatic physiological and psychological changes to return to a prepregnant state. Here is the 80/20 breakdown of the most critical adaptations and care principles. 1. Reproductive System & Involution The most vital reproductive change is uterine involution, the process by which the uterus contracts, reduces in size, and heals. The uterine fundus typically descends from the umbilicus at a rate of 1 cm (one fingerbreadth) per day, returning to the pelvis by 10 to 14 days postpartum. Effective contraction prevents uterine atony (a soft, boggy uterus), which is the primary cause of early postpartum hemorrhage. As the uterus heals, patients expel vaginal discharge called lochia in three stages: Lochia rubra: Deep red mixture of blood and tissue (days 1–4). Lochia serosa: Pinkish-brown discharge containing leukocytes and serous fluid (days 4–10). Lochia alba: Creamy white or light brown discharge (days 10–14, sometimes lasting weeks). 2. Systemic Physiologic Shifts Cardiovascular: Blood volume drops rapidly after birth. The body eliminates excess fluid through intense postpartum diuresis (urination) and diaphoresis (sweating). Crucially, coagulation factors remain elevated for 2 to 3 weeks, putting the patient at high risk for blood clots (thromboembolism). Urinary: Bladder tone frequently decreases due to swelling, trauma, or regional anesthesia. Urinary retention is a major concern because a full bladder displaces the uterus, inhibiting its ability to contract and increasing bleeding risks. Gastrointestinal: Bowel tones and peristalsis are sluggish, frequently leading to constipation, which is often worsened by the fear of perineal pain during bowel movements. Endocrine & Lactation: After the placenta is delivered, estrogen and progesterone levels plummet, allowing prolactin to initiate breast milk production. Colostrum is produced first, and mature milk typically arrives 4 to 5 days after birth. Infant suckling releases oxytocin, which triggers the milk "let-down" reflex and also causes painful uterine contractions known as afterpains. 3. Psychological Adaptations & Bonding Birthing parents typically progress through Reva Rubin's three phases of role attainment: Taking-in phase: The first 24-48 hours where the parent is dependent, focused on their own needs (sleep, food), and processes the birth experience. Taking-hold phase: The parent becomes more independent, assumes caregiving tasks, and seeks reassurance. Letting-go phase: The parent embraces the new normal and incorporates the infant into their family life. Partners undergo a parallel process characterized by engrossment—an intense absorption, attraction, and preoccupation with the newborn. 4. Postpartum Care & Complications Physical Care: Nurses routinely monitor vital signs, uterine tone, lochia, and perineal healing. Perineal pain is managed using ice packs (first 24 hours), sitz baths, witch hazel, and analgesics.

OB | PPH

IA

https://statstitch.etsy.com 1. Definition and Recognition Definition: The standard definition of PPH is a cumulative blood loss of ≥ 1000 mL, or any blood loss accompanied by signs and symptoms of hypovolemia within 24 hours following delivery, regardless of whether the delivery was vaginal or cesarean. Classification: PPH is considered "primary" (or immediate) if it happens within the first 24 hours, and "secondary" (or delayed) if it happens between 24 hours and 12 weeks after delivery. Primary PPH is vastly more common and clinically severe. Clinical Presentation: PPH often occurs suddenly, without warning, and in the absence of traditional risk factors. Because healthy pregnant patients can tolerate up to 15-20% blood volume loss with minimal symptoms, the sudden onset of tachycardia, tachypnea, and delayed capillary refill are crucial early warning signs of intravascular depletion. 2. The 80% Culprit: Uterine Atony Prevalence: Uterine atony is the single most important concept in PPH, accounting for approximately 80% of all cases. Pathophysiology: Under normal circumstances, the uterus contracts immediately after the placenta is delivered, which constricts the spiral arteries and stops bleeding. Atony occurs when this vital muscular contraction fails to happen. Diagnosis: The clinical diagnosis of atony is primarily physical; instead of feeling a firm, contracted uterus, the clinician will palpate a soft, pliable, and "boggy" uterus. 3. Other Critical Causes (The Remaining 20%) Retained Placenta: Retained placental tissue mechanically prevents the uterus from contracting fully. It is imperative that every placenta is carefully inspected after expulsion to detect any missing cotyledons. Genital Tract Lacerations: Tears in the cervix, vagina, or perineum can cause steady, life-threatening blood loss, and should be suspected if bleeding is excessive despite a firm, contracted uterus. Abnormal Placentation: Conditions like placenta accreta, increta, and percreta occur when the placenta abnormally attaches to or invades the uterine wall. Risk factors dramatically increase with prior cesarean sections and placenta previa. Coagulopathy & Rare Events: Acquired or congenital blood clotting defects can lead to a vicious cycle of bleeding. Other exceedingly rare but catastrophic causes include uterine inversion (where the uterus turns inside out) and uterine rupture. 4. Immediate Management & Interventions PPH is an unequivocal emergency requiring the immediate mobilization of all available resources. Initial Resuscitation: Providers must quickly establish two large-bore intravenous (IV) lines, begin crystalloid infusions, cross-match blood, and assess clotting. The mainstay of blood replacement is packed red blood cells (PRBCs), though a 1:1:1 ratio of PRBCs, fresh frozen plasma, and platelets is recommended for severe hemorrhage. Bimanual Uterine Massage: This is a crucial, immediate manipulative therapy that is often successful in stimulating uterine contraction while other treatments are prepared. Uterotonic Medications: Medical management includes agents designed to force the uterus to contract, such as IV/IM Oxytocin, Methylergonovine (avoided in hypertensive patients), Misoprostol, Dinoprostone, and 15-methyl PGF2a

https://statstitch.etsy.com Prematurity & Membrane Rupture Preterm Labor: Regular contractions causing cervical change before 37 weeks. The primary goal is delaying birth 48 hours using tocolytics to administer corticosteroids for fetal lung maturity. PPROM: Amniotic sac rupture before 37 weeks. The greatest risk is infection; nurses must monitor temperature, avoid digital exams, and administer antibiotics. Infection & Intrapartum Interventions Chorioamnionitis: Intra-amniotic infection presenting with maternal fever, uterine tenderness, and fetal tachycardia. Treatment requires IV antibiotics and prompt birth. Labor Augmentation: Used for dystocia via oxytocin or amniotomy. Oxytocin requires 1:1 nursing to monitor for tachysystole and fetal distress. Operative Vaginal Birth: Vacuums/forceps expedite the second stage. The cervix must be fully dilated, membranes ruptured, and the fetal head engaged. Fetal Distress & Malpresentation Nonreassuring FHR: Indicates hypoxia (bradycardia, late decelerations). Nurses must perform intrauterine resuscitation: stop oxytocin, reposition laterally, increase IV fluids, and apply oxygen. Breech Presentation: Fetus presents buttocks/feet first. Managed via External Cephalic Version (ECV) or Cesarean, requiring continuous FHR monitoring. Meconium-Stained Fluid: Indicates hypoxia, risking aspiration. Nurses assist with amnioinfusion and prepare for neonatal resuscitation. Obstetrical Emergencies (Require Rapid Response) Umbilical Cord Prolapse: Cord exits cervix before the fetus. The nurse must immediately use a sterile gloved hand to elevate the fetal presenting part off the cord and prepare for emergent Cesarean. Placental Abruption: Premature separation of the placenta. Identified by sharp abdominal pain, a board-like abdomen, and fetal bradycardia. Requires immediate Cesarean and fluid resuscitation. Uterine Rupture: Tearing of the uterine wall, highest risk during Trial of Labor After Cesarean. Signs include sudden pain, loss of fetal station, and ominous FHR patterns, necessitating immediate Cesarean. Shoulder Dystocia: Head emerges but retracts ("turtle sign"). Nurses must immediately implement the McRoberts maneuver (elevating legs) and apply suprapubic pressure. Psychosocial Support Emergencies disrupt birth plans and can lead to fetal loss. Nurses must provide a supportive presence, actively listen, and facilitate healthy grieving.
