XIV. MATERNITY NURSING
A. First trimester (Week 1 through Week 13):
- Assessment: a. Presumptive Signs of Pregnancy: Amenorrhea – what is the name of the hormone that causes this? PROGESTERONE N/V Frequency – can be one of the first signs. UTERUS STRETCHES IMMEDIATELY. Breast Tenderness – excess hormones b. Probable Signs of Pregnancy: A positive pregnancy test – since it is based on the presence of hCG levels. There are other conditions that can ↑ hCG levels: hydatidiform mole; drugs. Goodell’s sign (softening of CERVIX; second month) Chadwick’s sign (bluish color of vaginal mucosa and cervix; week 4.) Hegar’s sign (softening of the lower uterine segment; 2nd/3rd month) Uterine enlargement Braxton Hicks contractions (throughout pregnancy; move blood through the placenta). Pigmentation/changes of skin Linea nigra – DARK LINE CENTER OF ABDOMEN Abdominal striae – STRETCH MARKS Facial chloasma (mask of pregnancy) Darkening of the areola (around the nipple) c. Positive Signs of Pregnancy: Fetal heartbeat: Doppler→ 10
- 12 weeks Fetoscope→ 17 - 20 weeks Fetal movement Ultrasound Hurst Review Services 179 d. Miscellaneous Information:
Gravidity: # of times someone has been pregnant
Parity: # of pregnancies in which the fetus reaches 20 WEEKS.
Viability 24 weeks = Infant has the ability to live outside the uterus. A 20 week baby is NOT considered VARIABLE.
TPAL: acronym that gives you further information on parity T= term P= preterm A= abortion – this includes spontaneous and elective abortions L= living children
Nagele’s Rule: Find the first day of the LMP Add 7 days Subtract 3 months Add 1 year
- Client Education/Teaching: a. Nutrition: 4 food groups Increase calories by 300 per day after the first trimester Adolescent: ↑ calories by 500 after first trimester Increase protein to 60 grams per day b. Weight Gain: Expect to gain 4 pounds in the first trimester c. Prenatal vitamin supplements: Why don’t women like to take iron? It causes CONSTIPATION AND GI UPSET. Take iron with vitamin C to enhance absorption. Folic acid prevents? NEURAL TUBE/SPINAL BIFIDA defects Daily dose? 400 mcg/day 180 Hurst Review Services d. Exercise Rules: No high impact; WALKING and swimming are best. No heavy or unaccustomed exercise program. No overheating (no hot tubs or electric blanket either) Why? INCREASES TEMPERATURE = birth defects Exercise Rule: Don’t let your heart rate get above 140.
If the heart rate goes over 140bpm = CARDIAC OUTPUT and uterine perfusion will drop. e. Danger Signs: Sudden gush of vaginal fluid Bleeding Persistent vomiting Severe headache Abdominal pain Increased temps Edema No fetal movement f. Common Discomforts: N/V Breast Tenderness Frequency Tender gums Fatigue Heartburn Increased vaginal secretions Nasal stuffiness – nasal sprays, steams. Excess estrogen Varicose veins Ankle edema – elevate those feet. Hemorrhoids Constipation- eat more fiber. Walk a lot. Backache Leg cramps g. Medications: What are you going to tell the pregnant person about taking medications? DON’T unless you ask the doctor. h. Smoking: What are you going to tell them? STOP Hurst Review Services 181 i. Physician visits: How often should a pregnant client visit the physician? First 28 weeks: ONCE A MONTH 28-36 weeks: TWICE A MONTH 36 weeks: weekly until delivery j. Ultrasounds: Before an ultrasound what will you ask the client to do? DRINK WATER To distend the bladder → pushes CLOSE to abdominal surface.
What about an ultrasound prior to a procedure? VOID B. Second Trimester (Week 14 through Week 26): S/S:
- Weight Gain: Expected weight gain per week? 1 POUND
- Should the client still be experiencing? Nausea and vomiting NO Breast tenderness YES Frequency NO,
- Quickening: What is it? FETAL MOVEMENT
- Fetal Heart Rate: What should the fetal heart rate be during the second trimester? 120-160BPM
- Miscellaneous Information: Kegel Exercise: Exercise to strengthen the pubococcygeal muscles; these muscles help stop urine flow, help prevent uterine prolapse. TESTING STRATEGY *120 to 160: normal *110 to 120: worried and watching *Less than 110 panic 182 Hurst Review Services Pregnancy is considered term if it advances to 27 to 40 weeks. C. Third Trimester (Week 27 through Week 40):
- Assessment: a. Expected weight gain per week? NO MORE THAN 1LB A WEEK b. Monitor BP and report any INCREASE from the baseline. c. Fetal Heart Rate: 120-160BPM d. How is fetal position/presentation determined? LEOPOLDS MANEUVERS What should you have the client do first? VOID If the client is having contractions, should these maneuvers be done during or between contractions? BETWEEN
- Client Education/Teaching: a. Signs of labor:
- Lightening: Usually occurs 2 before term.
When the presenting part of the fetus (usually the head) descends into the pelvis. The client will feel less CONGESTED, and breathe easier, but urinary FREQUENCY is a problem (again). 2) Engagement: The largest presenting part is in the pelvic inlet. Hopefully, the fetal head is presenting first. 3) Fetal stations: measured in cm, measures the relationship of the presenting part of the fetus to the ischial spines of the mother. Hurst Review Services 183 4) Signs of labor (cont.): Braxton Hicks Contractions: More frequent and stronger Softening of the CERVIX Bloody show Sudden burst of ENERGY, called NESTING Diarrhea Rupture of the MEMBRANES b. When should the client go to the hospital? When the contractions are 5 minutes apart or when the membranes RUPTURE What are we worried about when membranes rupture? PROLAPSE CORD D. Diagnostic Tests:
- Non-stress test: (NST) a. Want to see two or more accelerations of 15 beats/minute (or more) with fetal movement. Acceleration is when the fetal heart rate has an abrupt increase from the baseline. This is visualized on the fetal heart monitor. The increase is > 15 beats/min. above the baseline and lasts at least 15 seconds but the heart rate should come back to baseline within 2 min.
b. Each increase should last for 15 seconds and recorded for 20 min. c. Do you want this test to be reactive or non-reactive? REACTIVE. 2. Biophysical Profile Test: (BPP) a. Done in the trimester, but can be done at 32-34 weeks in high risk pregnancy. High risk pregnancy may have a BPP every week or twice a week in 3rd trimester. b. Measurements are done by ultrasound, each parameter counts points. 10/10 is great 184 Hurst Review Services c. BPP measurement.
- Heart rate – was Non-Stress Test (NST) reactive?
- Muscle tone Does baby have at least 1 flexion – extension movement in 30 minutes?
- Movement Does the baby move at least 3 times in 30 minutes?
- Breathing Does the baby have breathing movements at least once in 30 minutes?
- Amniotic fluid Is there enough fluid around the baby? d. Observation time is 30 minutes. e. Results are evaluated: 8-10 good 6 worrisome < ominous
- Contraction Stress Test (CST): Oxytocin Challenge Test: a. Done when the NST is NONREACTIVE. b. Performed on high risk pregnancies: preeclampsia, maternal diabetes, and any condition in which placental insufficiency is suspected. c. This determines if baby can handle the stress of a UTERINE CONTRACTIONS. d. Uterine contractions decrease blood flow to the uterus and to the placenta.
f. A s head crowns tear amniotic sac. You will only have to tear the amniotic sac if it has not already ruptured. g. P l a ce hand on fetal head and apply gentle pressure. This will prevent the baby from coming out too fast. h. When the head is out feel for cord around neck. i. Ease each shoulder out – do not pull on the baby. j. The rest will deliver fast. k. Keep baby’s head down. l. Dry baby. m. Keep baby at level of uterus. n. Place on mother’s abdomen. o. Cover baby. p. Wait for placenta to separate/deliver. q. Can push to deliver placenta. Must deliver within 30 mins. r. Inspect placenta for intactness. s. Tie the cord off with a piece of cloth or shoestring. Place one knot about 4 inches from the baby’s navel and the second knot about 8 inches from the baby’s navel. t. Check firmness of uterus. 188 Hurst Review Services G. Normal Post-Partal Period:
- Assessment: a. Vital signs: T→ may increase to 100. during 1st to 4 hours BP→ stable HR→ 50-70 common for 6- days. TACHYCARDIA – HEMORRHAGE. b. Breasts: Soft for 2 to 3 days, then engorgement. c. Abdomen: Soft/loose; diastasis recti d. GI: Is hunger common? YES e. Uterus: Immediately after birth the fundus is in midline 2 to 3 fingers breadths below umbilicus.
A few hours after birth it rises to level of umbilicus or one FB above. Want fundus to be FIRM What is the first thing you do if the fundus is boggy? MASSAGE the fundus until it is firm and then check for BLADDER distention. Fundal height will descend one FB/day. What is the proper term used when the fundus descends and the uterus returns to its pre-pregnancy size? INVOLUTION Afterpains are common first 2-3 days and will continue to be common if the mother chooses to what? BREASTFEED, BECAUSE OF THE SURGE OF OXYTOCIN. TACHYCARDIA + POSTPARTUM? THINK HEMORRHAGE Bladder distention is suspected when the uterus is above the expected level or is not in the midline. (Usually moved to the right) A distended bladder will not allow the uterus to contract normally which increases the chance of hemorrhage. Hurst Review Services 189 f. Lochia: Rubra: 3-4 days: Color: DARK RED Serosa: 4-10 days: Color: PINKISH BROWN Alba: 10-28 days (can be as long as 6 weeks): Color: WHITISH-YELLOW Clots are okay as long as they are no larger than a NICKEL g. Urine output: DIURESIS should begin 24 hours after delivery. Is dehydration possible? YES Why should the legs be inspected closely? DVT 2. Tx: a. Perineal Care: Ice packs intermittently for first 6-12 HOURS-decrease EDEMA Warm water rinses
Sitz baths 2-4 times per day These are indicated if the client has an episiotomy, laceration, or hemorrhoids. Anesthetic sprays Change pads frequently Peripad Rule: We do not want the client to saturate more than 1 peripad/hr. Teach to report foul smell. Report lochia CHANGES. b. Bonding: Bonding between mother and baby and father and baby develops trust. In the infant, trust is not only an emotional need but a PHYSIOLOGICAL need. How does newborn benefit physiologically from bonding? Stabilize HR Improves O2 sats Regulates the infant TEMPERATURE. Conserves calories Breasts can change in temperature to warm or cool the infant. This is called kangaroo care: mom or dad places baby “skin to skin” on their chest. The baby is wrapped inside the parent’s shirt or covers and held for 1 hour at least 4 times a week. 190 Hurst Review Services c. Breast Care: 1) Breast feeding mothers: Cleanse with WARM water after each feeding; let air dry. Support GOOD SUPPORT BRA Ointment for soreness or express some colostrum and let it DRY. Breast pads – absorb MOISTURE Mother needs to initiate breast feeding ASAP after BIRTH . If breast feeding interrupted: mom can PUMP. Increase caloric intake by 500 calories.
Fluid/milk intake: Eight to ten--- eight ounce glasses of fluid a day. 2) Non-Breast Feeding Mothers: Ice packs, breast BONDERS, chilled cabbage leaves Chilled cabbage leaves DECREASE inflammation and decrease engorgement No stimulation of the breast 3. Complications: a. Postpartum infection: Infection within 10 days after birth; E. Coli/Beta hemolytic strep Teach proper hygiene (front and back cleansing) and hand washing. Usually get cultures and antibiotics b. Postpartum hemorrhage:
- Definition: Early- more than 500CC blood lost in first 24 hours AND a 10% drop from admission hematocrit. You must have both to be true!!!! Late-after 24 hours, up to 6 weeks postpartum Hurst Review Services 191
- Causes: uterine atony, lacerations, retained fragments, forceps delivery c. Mastitis: Staphylococcus Usually occurs around 2- WEEKS Treatment: Bed rest Support BREAST Binding can cause more stagnation. Only use if breastfeeding is discontinued permanently. Chilled cabbage leaves If mom is going to continue to breastfeed, she needs to initiate breast feeding frequently or PUMPING. PCN (ok with breastfeeding) Pain medication Heat Feed baby AND TAKE THE MEDICATION
Always offer the affected breast FIRST H. Newborn Care:
- Immediate Care: a. Suction b. CLAMP and CUT the cord c. Maintain temperature. Medications used to halt excessive postpartum hemorrhage: Oxytocin (Pitocin®) Methylergonovine Maleate (Methergine®) Carboprost Tromethamine (Hemabate®) 192 Hurst Review Services d. Apgar: Done at 1 and 5 minutes Looks at HR, R, muscle tone, reflex irritability, color Want at least 8-9. e. Erythromycin (gtts or ointment) for eye prophylaxis for Neisseria gonococcus Erythromycin will also kill the most rapidly growing STD: Chlamydia. f. Phytonadione (Aquamephyton®) promotes formation of clotting factors INJECTION. VASTUS LATERALIS
- Cord Care: a. Dries, and falls off in 10 to 14 days b. Cleanse with each diaper change using ALCOHOL or NORMAL SALINE c. Fold diaper BELOW cord d. No immersion until cord falls off; watch for INFECTION.
- Complications: a. Hypoglycemia: Why do babies sometimes experience hypoglycemia after birth? Because they are not getting glucose from MOTHER. Babies at greatest risk for hypoglycemia include those that are large for gestational age, small for gestational age, preterm, and babies of diabetic moms. b. Pathologic Jaundice:
When does pathologic jaundice occur? FIRST 24 HOURS Usually means Rh/ABO incompatibility c. Physiological Jaundice: When does physiological jaundice (hyperbilirubinemia) occur? AFTER 24 HOURS Due to normal hemolysis of excess RBC’s releasing bilirubin, or liver immaturity. Hurst Review Services 193 d. Rh Sensitization or Rh factor: Occurs when you have an Rhmother with an Rhfetus
- First Pregnancy: Rh+ blood from baby comes in contact with mother’s Rhblood. Mom’s blood is most likely to come in contact with the baby’s blood when the placenta separates at birth. It can also happen during a miscarriage, amniocentesis, or when there is trauma to Mom’s abdomen. Mother’s body looks at the Rh+ blood as a foreign body, an antigen. Mother produces antibodies to the baby’s Rh+ blood. The first offspring is not affected by the antibodies
- Second Pregnancy: An Rhsensitized mom gets pregnant again: She’s got these antibodies waiting for the Rh+ blood to come around so she can attack it. The chances of an RhMom having antibodies to Rh+ blood increases with each pregnancy and each exposure to Rh+ blood because once you have these antibodies they never go away. The antibodies the Mother has made enters baby thru placenta→
