Source: Durham & Chapman, Maternal-Newborn Nursing 4e, Chapter 12, pp. 399-428 (textbooks/DURHAM_OB_CH12.pdf, also in textbooks/exam03/). Week 10 reading (OB Lectures 6-7, October 28); on Exam 3. Lecture slides: raw/nsg210_wk10_OBLecture4.md (postpartum section, slides 1-24). Complications (hemorrhage, infection, VTE, mood disorders) are in nsg210-durham-ch14-high-risk-postpartum; psychological adaptation is in nsg210-durham-ch13-transition-to-parenthood.

Learning Outcomes

  1. Describe the physiological changes of the postpartum period.
  2. Identify critical elements of postpartum assessment and nursing care.
  3. Discuss safe and effective postpartum nursing care.
  4. Outline the critical elements of discharge teaching.

Nursing diagnoses: pain (uterine involution, perineal trauma, engorgement); risk for infection (perineum, mastitis); risk for fluid volume deficit from uterine atony; risk for impaired urinary elimination; risk for constipation; knowledge deficit about postbirth health promotion.

Expected outcomes: firm fundus with scant to moderate lochia; spontaneous void within 2 to 4 hours of birth; at least 10 glasses (80 oz) of fluid a day with a high-fiber diet; verbalizes warning signs and follow-up plan.

I. Overview

Box 12-1, postpartum assessment overview: vital signs, pain, breath and heart sounds; labs (CBC, rubella, Rh status); vaccines (Tdap, influenza, pneumococcal, COVID-19); breasts; uterus; bladder; bowel; lochia; episiotomy, lacerations, perineum, hemorrhoids; lower extremities; emotions, bonding, fatigue, psychosocial factors.

II. Reproductive System

A. Uterus and involution

Assessment frequency for fundus, VS, RR and temperature (same schedule for all):

Hemorrhage timing:

Fundal assessment technique:

Expected fundal findings:

Deviations:

Critical Component, uterine atony (boggy uterus):

B. Endometrium and lochia

Table 12-2, stages of lochia:

Stage Days Expected Abnormal
Rubra 1-3 Bloody, small clots, moderate to scant, fleshy odor; flow increases on standing or breastfeeding Large clots, saturating a pad in 1 hour, foul odor, placental fragments
Serosa 4-10 Pink or brown, scant; flow increases with activity Rubra continuing after day 4, heavy amount, foul odor
Alba 10 on Yellow to white, scant, fleshy odor Bright red bleeding (possible late PPH), foul odor

Amount (Fig. 12-3):

Clots and blood loss:

Lochia teaching:

C. Clinical judgment: excessive bleeding

Box 12-2, Maternal Early Warning Criteria (urgent bedside evaluation if a value persists, recurs, or comes with other abnormal values):

While waiting for the clinician: secure free-flowing IV access, increase VS frequency, give oxygen, have a catheter, uterotonics and lab supplies at the bedside, consider a rapid response.

D. Vagina and perineum

Laceration degrees:

Notes:

Assessment:

Comfort and infection prevention:

E. Pain management (Clinical Judgment)

F. Breasts

Expected breast findings (both groups): day 1 soft and nontender; day 2 slightly firm and nontender; day 3 firm, tender and warm.

Box 12-3, breast care:

XI. Contraception (Table 12-3)

Method Failure rate Key points
Abstinence 0% Only method with no failure if practiced consistently
Natural family planning 24% Needs regular cycles and monitoring of temperature and mucus
Withdrawal 22% No cost; no STI protection
Lactational amenorrhea (LAM) see table Requires exclusive breastfeeding; a barrier method improves effectiveness
Male condom / female condom 18% / 21% OTC; only methods here that protect against STIs
Sponge 12% (no prior births), 24% (prior births) OTC, one-time use, activate with water
Cervical cap 14% (no prior birth), 29% (prior birth) Leave at least 6 hours after intercourse; up to 48 hours
Diaphragm 12% Must be refitted after birth or large weight change; leave 6 hours after intercourse, up to 24 hours; toxic shock and UTI risk if left too long
Spermicide 28% Frequent use contraindicated if at risk for HIV
Combined oral contraceptive 9% Contraindicated with DVT or PE history, hypertension, heart disease, active cancer, smokers 35 or older, clotting disorders, liver disease; raises clot, MI and stroke risk
Progestin-only pill 6% (text) Safe during lactation; take at the same time daily
Depo-Provera 3% Injection every 3 months; safe in lactation; weight gain, decreased bone density, delayed return of fertility
Patch 9% Weekly for 3 weeks, then 1 week off; clot risk like the pill; may be less effective in larger women
Vaginal ring 9% In for 3 weeks, out for 1 week
IUD (copper or levonorgestrel) 0.8% / 0.2% LARC; can be placed immediately postpartum; safe in lactation; contraindicated with PID in the past 3 months; copper IUD works as emergency contraception within 7 days
Implant 0.05% LARC; one rod in the arm; can be placed postpartum; safe in lactation
Emergency contraception see table Within 72 to 120 hours; OTC at 17 or older; not regular birth control
Vasectomy / tubal ligation 0.15% / 0.5% Permanent; after vasectomy use backup until two sperm tests are clear

AWHONN supports insurance coverage for all FDA-approved contraceptives (Critical Component).
