Exam 1 Study Guide NUR 346 MATERNAL NEWBORN NURSING
1. Goal of maternal newborn nursing: a. A safe and satisfying experience for the mother, her family, and her baby. 2. Nursing Roles in Women’s Health: a. RNs work as labor nurses, mother-baby nurses, lactation consultants (help teach breastfeeding), clinic nurses, newborn nursery nurses, home health nurses, NICU nurses and gynecology nurses b. RNCs are RNs who have demonstrated clinical expertise in a field and are certified by a national organization c. Nurse Practitioners are usually Master’s prepared nurses who function as advanced practice nurses. NPs usually focus on ambulatory nursing. Women’s Health NPs or Family NPs are examples. Neonatal NPs work in newborn nurseries and NICUs. NPs perform H&Ps, order diagnostic tests and procedures. d. Certified Nurse Midwives function similarly to NPs but also perform deliveries and care for newborns e. Clinical Nurse Specialists have Master’s degrees and specialized knowledge and competence in a specific clinical area 3. Family Centered Childbirth a. Provision of safe, quality nursing care that recognizes, focuses on and adapts to the physical and psychosocial needs of the pregnant woman, her family and her newborn. b. Fosters family unity and promotes and protects the physiologic well-being of the mother and newborn. c. Fathers, siblings, grandparents, friends encouraged to participate in the birth process d. Families make choices based on their desires. These may include having a physician or midwife attend their births or whether to deliver in a hospital, birth center or at home e. Hospitals now have both Labor & Delivery (L&D) rooms but also Labor, Delivery, Postpartum (LDRP) suites f. The mom dictates who is in the room and who is considered family 4. Philosophy of Family-centered maternal/Newborn Nursing a. Pregnancy and childbirth are usually normal healthy events within the family. b. Childbirth affects the whole family and marks the beginning of a new set of important relationships. c. Families are able to make decisions about care if given the proper information. d. A maternal/newborn nurse serves as an advocate for the rights of all family members, including the fetus. e. Personal, cultural, and religious attitudes influence the meaning of pregnancy and birth within the family. f. Promoting health through role modeling, teaching, and counseling is important to the future health of the community in which the family lives g. Advocate for pt desires and preferences: cultural etc 5. Important Features of Family Centered MNN a. Prenatal and parent education classes. b. Family participation in all aspects of pregnancy & birth. c. Presence of support person for complicated births or cesarean sections d. Use of homelike birth settings. e. Flexible policies regarding routine procedures. f. Flexible rooming in policies. g. Early extended parent-newborn contact. h. Family involvement in care of the mother and newborn. i. Early post birth discharge with close follow up. j. Nontraditional labor and birth settings k. Single room maternity systems which may be called LDR or LDRP. 6. Culturally Competent Care a. Religion/social beliefs b. Presence of extended family c. Communication patterns d. Beliefs and understanding about concepts of health and illness e. Beliefs about propriety of physical contact with strangers f. Education 7. Legal Considerations a. Scope of practice defined as limits of nursing practice as set forth in state statutes b. Health maintenance and disease prevention c. Expanded practice roles include planning care, diagnosis, prescription privileges 8. Standards of Nursing Care a. Establish minimum criteria for competent, proficient delivery of nursing care b. Designed to protect the public and used to judge quality of care provided
c. Legal interpretation of actions within standard of care is based on what a reasonably prudent nurse with similar education and experience would do in similar circumstances d. ANA, AWHONN help define e. Nurse who fails to meet appropriate standards of care may be subject to allegations of negligence or malpractice
9. AWHONN Standards of Care a. Comprehensive nursing care of women and their infants focuses on assisting individuals and families to achieve their optimal health. b. Health education is an integral aspect of comprehensive nursing care, Health teaching focuses on health promotion, maintenance, and restoration. c. The qualifications of personnel authorized to provide care are delineated. The scope of practice is clarified in written policies, procedures, and protocols. d. The nurse must be clinically competent to provide comprehensive care for the mother and newborn. The nurse is legally accountable and responsible for the care given. e. Practice settings must have sufficient numbers of qualified nursing personnel to meet patient care needs. f. Ethical principles guide the clinical judgment of nurses caring for mothers and infants. g. Research and research findings are used to improve client outcomes. h. Systematic evaluation using specific clinical indicators is done to ensure quality of care 10. Informed Consent= Shared Decision Making a. Protects patient right to autonomy and self-determination b. No action may be taken without that person’s consent c. Usually consent obtained by physician or midwife; RNs may witness client’s signature giving consent d. If nurse determines that patient doesn’t understand procedure or risk, RN must notify MD e. In most states, pregnant teenagers are considered emancipated and may give consent for herself f. Refusal of treatment, medication, procedure requires signed form releasing provider and hospital from liability. Jehovah’s Witness patient may refuse blood transfusions or Rhogam 11. Pelvic Exam Consent a. July 1, 2020 Florida statute to require written consent for any pelvic exam. 12. Right to Privacy a. Right of person to keep person and property free from public scrutiny b. Avoid unnecessary exposure of women’s body c. Avoid discussing her care with people not involved in her care
19. Global Statistics a. Between 250,00 and 343,000 women are estimated to die each year from complications associated with pregnancy and childbirth. b. Ninety-nine per cent of these deaths occur in the developing world where most women’s lives are restricted by illiteracy, poor education and poverty. c. For every woman who dies in childbirth, around 20 more suffer injury, infection or disease – that’s a total of some 10 million women each year. d. Fewer than 50% of all births in developing countries take place with the help of a skilled birth attendant. e. A child whose mother dies during childbirth is 3-10 times more likely to die before his or her second birthday. f. Spacing births two or more years apart significantly reduces the risk of maternal and newborn death. g. In the developed world, a woman's lifetime risk of dying during or following pregnancy is one in 4,300 but in Sub- Saharan Africa that risk is one in 31. h. Some 222 million women who would prefer to delay or avoid pregnancy lack access to, or do not use, safe and effective contraception. i. Each year, more than 50 million women give birth at home without the help of a trained professional. 20. Cesarean Birth a. 1/3 of children in the US are born by c-section. 31.9% b. The c-section rate increased 50% over the past 10 years. c. 1965 C/S rate was 4.5% 21. NTSV Cesarean Birth Rate a. Nulliparous, Term, Singleton, Vertex b. #3. Florida c. Overall C-Section Rate: 36.5% d. Low-Risk C-Section Rate: 31% e. Healthy People 2020 target was 23.9 percent. 22. Family a.

Dual career: both parents have jobs iii. Childless: just a couple no children iv. Extended: includes grandparents, uncles, aunts and other relatives who live nearby or in same house v. Extended kin network: extended families with several generations vi. Single parent: one parent with children vii. Stepfamily: family formed from a remarriage and divorce viii. Binuclear: large, interconnected family, with one household headed by the ex-wife and the other household headed by the ex-husband, with the child being a member of both. ix. Nonmarital: only related to one adult but have established child-parent relationships with both x. Gay and Lesbian: two moms or two dads c. Eight Stage Family Life Cycle (Duvall)
