Nancy Pares, RN, MSN Metro Community College Apply basic knowledge of healthy maternal newborn care (recall from PN year) Describe ethical and legal issues of maternal newborn nursing, current legislation and community resources available. Demonstrate appropriate therapeutic communication and assessment of high risk pregnancy. Context ◦ Who is involved, what is the setting ◦ What other information is needed ◦ What personal beliefs of the nurse may impact the situation Clarification of the issues ◦ What are the ethical issues ◦ Who should decide the issue Identification of alternatives and potential outcomes Ethical reasoning ◦ What ethical theories have bearing on the situation ◦ Should some theories be given greater weight in the decision making process ◦ What legal or social constraints are factors ◦ What obligations might be present in the role of the nurse Resolution ◦ What is the best action in this situation ◦ What strategy should be used to carry out this action Evaluation ◦ What were the outcomes ◦ Should this same action be used in the future for similar dilemmas Professional Nurse Certified Registered Nurse Nurse Practitioner Clinical Nurse Specialist Certified Nurse Midwife Religion and social beliefs Presence and influence of the extended family Socialization within the ethnic group Communication patterns Beliefs and understanding about health and illness Permissible physical contact with strangers education Standards of care: ◦ Minimum criteria for competent, proficient, delivery of nursing care Institutional policies Ethical implications Scope of practice ◦ Defined by state Nurse Practice Act laws There was a duty to provide care. The duty was breached. Injury occurred. The breach of duty caused the injury (proximate cause). Divergence between rights of mother and rights of fetus: ◦ Mother may refuse fetal intervention. ◦ Fetal intervention may be forced on mother. Fetal research: ◦ Therapeutic vs. non-therapeutic Intrauterine fetal surgery: ◦ ◦ ◦ ◦ Therapy for anomalies incompatible with life Health of the mother and fetus is at risk Surrogate, frozen embryo, Female circumcision Abortion Nursing role ◦ Can be performed until point of viability ◦ After viability, if mother’s health in jeopardy ◦ Have right to refuse to assist ◦ Responsible for ensuring a qualified replacement is available Infertility Human stem cells Cord blood Maternal refusal for c/del Maternal refusal for fetal surgery Womens’ health standards by Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) State Boards Individual facilities policy A holistic interpersonal approach Adequate documentation Communication Updated and realistic policies and procedures Appropriate delegation Question deviations from the standar Follow chain of command Transforms research findings into clinical practice: ◦ Efficiency improvement ◦ Better outcomes ◦ Quality improvement Identify vulnerable periods during which malformations of various organs may occur and describe the resulting anomalies. Describe the function and structure of the placenta during intrauterine life. (review PN year) Mitosis: ◦ Exact copies of original cell Meiosis: ◦ Production of new organism Deletion ◦ Loss of chromosome material Translocation ◦ Misplacement Nondisjunction ◦ Chromosomes don’t separate correctly Karotype ◦ Chromosomal make up of an individual Mosaicism two or more genetically different cell populations in an individual Interphase Prophase Metaphase Anaphase Telophase First division: ◦ Chromosomes replicate, pair, and exchange information. ◦ Chromosome pairs separate, and cell divides. Second division: ◦ Chromatids separate and move to opposite poles. ◦ Cells divide, forming four daughter cells. Ovary gives rise to oogonial cells. Cells develop into oocytes. Meiosis begins and stops before birth. Cell division resumes at puberty. Development of Graafian follicle. Production of sperm First meiotic division: ◦ Primary spermatocyte replicates and divides. Second meiotic division: ◦ Secondary spermatocytes replicate and divide. Produce four spermatids. Uniting sperm and ovum form a zygote Ova are fertile for 12 to 24 hours Sperm are fertile for 72 hours Takes place in the ampulla of fallopian tube Capacitation: ◦ Removal of plasma membrane and glycoprotein coat ◦ Loss of seminal plasma proteins Acrosomal reaction: ◦ Release of enzymes ◦ Allows entry through corona radiata Zone pellucida blocks additional sperm from entering Secondary oocyte completes second meiotic division ◦ Forms nucleus of ovum Nuclei of ovum and sperm unite Membranes disappear Chromosomes pair up Fraternal: two ova and two sperm Identical: single fertilized ovum - Originate at different stages Cleavage Blastomeres form morula Blastocyst: - develops into embryonic disc and amnion Trophoblast: - develops into chorion Occurs 7 to 10 days after fertilization Blastocyst burrows into endometrium Endometrium is now called decidua Primary germ layers: ◦ Ectoderm ◦ Mesoderm ◦ Endoderm Metabolic and nutrient exchange Maternal portion: ◦ Decidua Fetal portion: ◦ Chorionic villi Fetal surface covered by amnion Chorionic villi form spaces in decidua basalis Spaces fill with maternal blood. Chorionic villi differentiate: ◦ Syncytium: outer layer ◦ Cytotrophoblast: inner layer Anchoring villi form septa Body stalk fuses with embryonic portion of the placenta Provides circulatory pathway from chorionic villi to embryo: ◦ One vein Delivers oxygenated blood to fetus: ◦ Two arteries Nutrition Excretion Fetal respiration Production of fetal nutrients Production of hormones Beginning development of GI tract Heart is developing Somites develop—beginning vertebrae Heart is beating and circulating blood Eyes and nose begin to form Arm and leg buds are present Trachea is developed Liver produces blood cells Trunk is straighter Digits develop Tail begins to recede Eyelids are closed Tooth buds appear Fetal heart tones can be heard Genitals are well-differentiated Urine is produced Spontaneous movement occurs Lanugo begins to develop Blood vessels are clearly developed Active movements are present Fetus makes sucking motions Swallows amniotic fluid Produces meconium Subcutaneous brown fat appears Quickening is felt by mother Nipples appear over mammary glands Fetal heartbeat is heard by fetoscope Eyes are structurally complete Vernix caseosa covers skin Alveoli are beginning to form Testes begin to descend Lungs are structurally mature Rhythmic breathing movements Ability to partially control temperature Bones are fully developed but soft and flexible Increase in subcutaneous fat Lanugo begins to disappear Skin appears polished Lanugo has disappeared except in upper arms and shoulders Hair is now coarse and approximately 1 inch in length Fetus is flexed Quality of sperm or ovum Genetic code Adequacy of intrauterine environment Teratogens Maternal effects: ◦ ◦ ◦ ◦ Malnutrition Bone-marrow suppression Increased incidence of infections Liver disease Neonatal effects: ◦ Fetal alcohol spectrum disorders (FASD) Seizures and hallucinations Pulmonary edema Respiratory failure Cardiac problems Spontaneous first trimester abortion, abruptio placentae, intrauterine growth restriction (IUGR), preterm birth, and stillbirth Decreased birth weight and head circumference Feeding difficulties Neonatal effects from breast milk: ◦ Extreme irritability ◦ Vomiting and diarrhea ◦ Dilated pupils and apnea Maternal effects: ◦ ◦ ◦ ◦ ◦ ◦ Poor nutrition and iron-deficiency anemia Preeclampsia-eclampsia Breech position Abnormal placental implantation Abruptio placentae Preterm labor Maternal effects: ◦ Premature rupture of the membranes (PROM) ◦ Meconium staining ◦ Higher incidence of STIs and HIV Fetal effects: ◦ IUGR ◦ Withdrawal symptoms after birth Marijuana: difficult to evaluate, no known teratogenic effects PCP - maternal overdose or a psychotic response MDMA (Ecstasy) - long-term impaired memory and learning Identify tests used to detect abnormalities, fetal well being and infertility management.
