Q

Ultrasound

10

A

Detect pregnancy – can detect FHR @ 6 weeks

Gestational age
Most accurate in 1st trimester – 4 to 7 days
Routine: at 14 to 16 wks

Position of fetus
Position of placenta
Size & dates of fetus – SGA, IUGR, LGA
Any gross fetal anomalies – nuchal neck, extrophy
Evaluation of fetal status
Alloimmunization: ascites, edema, fetal heart size

18
Q

First Trimester (9)

A
Respiratory Changes
Cardiovascular Changes
Gastrointestinal Changes
Breast Changes
Amenorrhea
Vaginal Secretions

Uterine Changes:
Goodell’s sign – cervical softening
Chadwick’s sign (levels of estrogen that cause characteristic bluish purple color that extends to vagina and labia)
Hegar’s sign – flexion and softening of uterus against cervix

19
Q

Maternal Psychological Responses: First Trimester

A

Uncertainty
Ambivalence
The self as primary focus

Role Transition throughout pregnancy
Progressively more aware of changes in her life
Mentors and support are critical

20
Q

Factors Influencing

Psychosocial Adaptations

A
Age
Multiparity
Social support
Absence of a partner
Abnormal situation
Socioeconomic status
21
Q

Second Trimester

A

Enlarging abdomen
Ballottement: 4 – 5 months (sudden tap on cervix during vaginal exam may cause fetus to rise and rebound to original position)
Chloasma: 4 – 5 months (brownish patches on face)
Straie Gravidarum: 6 months (stretch marks)
Braxton Hicks contractions (irregular painless contractions)
Linea Nigra: 5 months
Vascular spiders (tiny red elevations branching in all directions)
Quickening: 20 wks primigravida, 16- 18 wks multigravida

22
Q

Maternal Psychological Responses:

Second Trimester

A
Physical evidence of pregnancy
Fetus as the primary focus
Narcissism and introversion
Body image
Changes in sexuality
Introverted
4 month increase in libido
23
Q

Third Trimester

A

Waddling gait
Enlarging abdomen
Increased cardiac output
Placental senility – placenta starts to not be fully functional around 40 weeks and slows nutrients to infant
Lightening: primigravida/multigravida –> descent of fetal head, reduces pressure on diaphragm and makes breathing easier
Uterine souffle: soft blowing sound/maternal pulse

24
Q

Maternal Psychological Responses:

Third Trimester

A

Vulnerability - lack of concentration, hard to get in and out of a chair
Increasing dependence
Preparation for birth
Nesting behavior, taking classes, appointments

25
Maternal Tasks of Pregnancy | RUBIN
``` Rubin Seeking safe passage Securing acceptance Binding in to unknown child Learning to give of self ``` Mimicry, role play, fantasy, search for role fit, grief work
26
Stages of Family Development | Duvall
Duvall Prepare for role as childcare providers Reorganize home, family member duties, patterns of money management Reorient family relationships Each pregnancy—adjust to transitions in relationships with each other, children
27
Paternal Adaptation
Involvement Nurturer vs. Alienated Minimal vs. Dominating Couvade --> similar symptoms to mom “Announcement” phase -- father accepts pregnancy “Moratorium” phase -- adjusts to reality of pregnancy “Focusing” phase -- father becomes more involved and builds relationship
28
Adaptation of Siblings
Reactions influenced by age and level of involvement with pregnancy Toddlers -- Regression Preschoolers -- May not grasp reality of a baby in the family School-age -- Excited, happy Adolescents
29
Prepared Childbirth, Prepared Parenting
``` Preconception Early pregnancy Exercise Childbirth preparation Refresher courses Cesarean birth preparation -- Planned Vaginal birth after cesarean birth (VBAC) Breastfeeding Parenting/infant care Postpartum Classes for other family members -- Fathers, Siblings, Grandparents ```
30
Cochrane Collaboration
What works Epidural, spinal, inhalation (general anesthesia) What may work Not much evidence but good satisfaction: Immersion, Relaxation, Acupuncture, Non-opioid, Massage, Not much evidence, not much satisfaction: Hypnosis, Biofeedback, Aromatherapy, TENS, IV opioids
31
Lamaze International Desired Effect of Nursing Interventions: (4)
[Alleviate] Pain intensity Satisfaction with pain relief Sense of control in labor Satisfaction with childbirth experience
32
Lamaze International | Characteristics
Pyschoprophylactic – Stimulation/Response conditioning Controlled breathing may reduce pain during labor Labor “coach” Focal point, memory prompts Breathing patterns Slow chest breathing, Accelerated/Decelerated, Pant - Blow (modified pace with emphasis blow), Pushing (blow repeatedly with short puffs when urge to push increases) DON’T hold breath –> Valsalva maneuver can decrease maternal cardiac output and compromise fetal circulation “Natural Childbirth” – limited medication
33
Bradley Method of Natural Childbirth
Pregnancy and Childbirth are joyful, natural processes 12 week course Natural childbirth -> no medications preferred Exercises, relaxation, to prepare Abdominal breathing, and massage to manage labor Partner-coached -> an active role During the pregnancy, labor, and early newborn period Exercises Pelvic rocking - influences baby’s position (rock back and forth through pregnancy) Tailor sitting - strengthens lower back muscles
34
Other childbirth education instead of or in addition to
Dick-Read Method Fear -> Tension -> Pain Education reduces fear, which reduces pain Leboyer “Birth Without Violence” Odent Birthing pool of water to reduce low lumbar pain HypnoBirthing State of deep relaxation to block distractions, pain
35
Priority Nursing Diagnosis
``` ABCs Safety Maslow Hierarchy of Needs Physiological Comfort – warmth, pain management Fluids, Food, Elimination Safety - psychological Love and Belonging Self-Esteem Self-Actualization ```
36
Anticipatory Guidance
``` Appointment schedule Nutrition Calories/Weight gain Protein Vitamins Minerals/supplements Herbal supplements Exercise Breastfeeding Physiology of pregnancy Managing symptoms Warning signs Sleep patterns ```
37
Anticipatory Guidance x 2
``` Medication OTC medication Prescribed medication Sexuality Modifiable risks Work (physical & environmental stressors) Substance abuse Safety Seat belts Behavior/Lifestyle choices IPV ```
38
Pregnancy teens
``` Normal adolescent developmental tasks conflict with tasks of pregnancy May not seek prenatal care Non-compliant with care plan Not future oriented Acceptance of pregnancy hindered ```
39
Conflicting Developmental Tasks
``` Adolescence Personal value system Body image and sexuality Vocation or career Independence from parents Achievement of a stable identity ``` Pregnancy Seeking safe passage Acceptance of the pregnancy by self and others Acceptance of the reality of the unborn child Acceptance of the reality of parenthood Giving of oneself to the child
40
Physiologic Anemia
dilution of hemoglobin concentration Increase in plasma and the production of RBC does not speed up at the same pace as the increase in plasma No symptoms of anemia 34 weeks gestation
41
Effleurage and sacral pressure
Slow massage of abdomen during contractions Helps with back labor
