Final Flashcards
What does specialty nursing require?
commitment to praxis: knowing, being, doing
What processes are required for specialty nursing care?
grounded in relationship centered praxis:
professionalism
creative leadership
partnership
communication
systemic inquiry
collaboration
critical thinking
involves integrating nursing ethics!
Where does relationship centered praxis come from?
from our values/beliefs attained via personal experiences
Can you think of a situation from your own nursing practice where your relationship with your client/patient made a difference in providing care and/or enhanced health promotion?
From caring for the same patient over a span of three days straight I was able to build a therapeutic relationship with the patient and gain a better understanding of their hospitalization experience. From building this relationship with my patient, my patient really valued what I taught and took action. E.G. Educated the patient on mobilizing, patient motivated and instantly got up to mobilize.
What is perinatal nursing?
4
specialty
timeline: pregnant, L&D, up to d/c
family-centered: women, newborn, family as a whole within the context of their lives/environment
*more specifically women-focused care (because at center of each child-bearing relationship is a woman)
How do families/communities impact the women that we care for?
it is the social context in which women live in
alters attitude/accessibility to HC/relationships with HCP
What is neonatal nursing?
specialty
involves care for: neonate/infant (preterm/ill) up to 1 year, family
timeline: birth, hospitalization, d/c & follow up
Hx of maternity nursing
Early 20th century: birth transitioning from midwifery to hospital d/t high mortality rates of mom/baby
analgesics & separate rooms for L&D/nursery/decreased BF
were hospitalized up to 14 days
treated women as if they were sick
1960-1970’s: ICEA lobbied for changes
women’s movement also more powerful at this time
Family centered care model evolved & integrated into practice
When was positive pressure mechanical ventilation created
1970s
forever changed practice of the NICU
Two important aspect of neonatal nursing
1) characteristics of infants are considered (how they interpret/interact with environment)
2) physical/psychological growth & development is appreciated, influences of context on the infants vulnerability is considered
disadvantages of maternity care in Canada
Unequal in accessibility (rural areas, aboriginals)
Shortage of HCPs
Limited provinces offer midwifery care
How to fix these disadvantages?
2005: “Multidisciplinary Collaborative Maternity Care Project”
- addresses shortage of HCPs
2006: SOGC initiated “A National Birthing Strategy for Canada”
- goal is to improve maternity care in rural areas
Perinatal Services BC
- to develop regionalization of perinatal care in BC
4 aspects of nursing care central to relationship centered praxis
Communication and collaboration
Education, information and informed consent
Support and advocacy
Nursing ethics: relationships and care
C-ESN
What is communication
3
written, verbal and non-verbal
meanings exchanged among individuals to come to mutual understanding
basis for forming partnerships
What does collaboration involve
respecting choices
informed decision making (capacity/comprehension)
what should informed consent include
Explain situation
Description of recommendations (care, test, procedure)
Common risks/benefits
Alternative options
Support/Advocacy
To not just care for a women, but to be there with her in our caring.
Presence
Should provide: physical/emotional/informational support, adovacy (interpret wishes to others)
Can you think of a situation where the focus of care may not be clear and even present a moral dilemma for the caregiver?
If parents chose to have the baby terminated after finding out the baby has a disability. It would be difficult to set aside own beliefs/values.
Example of ethical practice
Nurse who is working in the intrapartum setting with a woman who has requested no analgesics for her labor. Morally, good nursing care respects this decision and works with the woman using non‑pharmacological methods to help her with her labor, and supports her in trying to realize her wishes.
8 CNA code of ethics
safe, competent, ethical care health & well being choice dignity confidentiality/privacy justice accountability quality practice environments
Why was family/women-centered care created
To get away from the medical model (sedative, partner absent for birth, neonates separated from parents)
What is family centered care?
Process of providing safe, skilled, and individualized care that responds to the psycho social needs of the woman and her family
pregnancy/L&D normal health events
factors impacting family centered care
Environment: e.g. separate birthing units/pp units
Collaboration between HCP e.g. anesthetist, doulas, lactation consultant
What definition of family best fits your family?
The family is a group of two + who are joined together by bonds of sharing and emotional closeness and who identify themselves as being part of the family (Friedman, 1992).
Can you think of families who may disagree with this definition?
Individuals who believe that anyone who is “blood” is family… no matter how close you are or the bond that you share.
common themes in family definitions
Concern for the well-being of family members is common to all of the definitions. (Use different words)
Beutler et al. (generational ties) and Stewart (future obligation) both refer to a time factor.
Friedman, Hanson et al., and Stewart all suggest that there is an element of family membership which is self-defined.
How does Davies view family?
Davies seems to view families as including children and their parents. This is commonly referred to as a “nuclear” family form. We could refer to these families as “childbearing.”
Developmental theories
families/individuals go through series of predictable stages of change over time
e.g. Erikson- childs emotional development
Piaget- childs cognitive development
Duvall
Focuses on the changes that families go through over time
Duvalls 8 stages:
I Married couples II Childbearing families III Families with pre-school children IV Families with school children V Families with teenagers VI Families launching young adults VII Middle-aged parents VIII Aging family members
For each stage there is a developmental task that needs to be completed!
Duvalls 2 developmental tasks for childbearing families
1) realizing the child really exists
- accepting new/added responsibility
- orienting to parent role
- begin bonding with child
2)adjusting family life to incorporate new baby
Duvalls developmental task for preschool/school-aged children
pre-school: to socialize/nurture children
School-aged: to promote success in school
5 tasks for ALL stages
physical maintenance
division of labor
allocation of resources
socialization
reproduction, recruitment, and release of family members.
How might families today relate to Duvalls 8 stages
Alot of families will not clearly fit into one of the 8 stages.
(single parent families, blended families, younger/older parents)
Depending on family you could say that they are working on a variety of stages at the moment.
How might families today relate to the 5 tasks Duval states is relevant to EACH stage
Most families relate to the 5 tasks relevant for each stage
However, they may implement them differently
How might Betty Davies describe families today
(believes families are subject to change over time!)
Believes families are resilient
Believes that when families are given challenges, if they have the appropriate support/resources they will work through it
6 factors influencing parental behaviour
Merenstein/Gardner
personality
personal experience
previous parenting
cultural background
the degree of attachment to the infant
the expectations the parents have of themselves/infant
7 Factors associated with stress/role strain (Kenner)
role ambiguity (i.e. single parents, unsure of who father is)
conflict (i.e. being torn between being a teenager/mom)
incongruity
overload (i.e. returning to work, supportive partner?, birth of twins)
underload
over qualification under qualification (i.e. young mothers, not enough life experience)
benefits of support during labour
research states it is associated with:
shorter labors
decreased use of oxytocin
fewer operative births/cesarean sections
and a higher rate of satisfaction for the mother
5 aspects of supportive care
emotional support
advocacy
comfort measures
supporting the husband/partner
offer information/advice
How long should BF be implemented for
exlusively for 6m
then continued for 2 years while introducing other foods
3 fetal periods
pre-embryonic (0-2)
embryonic (2-8)
fetal (9-term)
pre-embryonic period
0-2weeks
conception to implantation
fertilized egg differentiates into specialized cells, travels down fallopian tubes & implants in uterus
embryonic period
2-8weeks
rapid G&D occurs organogenesis heart starts beating rapid brain G&D arms/legs develop joints
fetal period
9weeks-Term
By week 14 placenta formed & functioning
organogenesis continues
major increase in size/weight in last 10-12 weeks
When does the placenta begin to develop
when is it structurally complete?
first week after conception
complete after 12 weeks
normal amount of amniotic fluid at term
800-1200
2000 HIGH- d/t GI/fetal anomalies
When does the embryos heart start beating?
day 17 after conception
What are the 4 hormones that the placenta produces?
Estrogen
Progesterone
Human chorionic gonadotrophin
Human placental lactogen
What does Estrogen do?
3
increases uterine growth
increases placental blood flow
increases glandular tissue in breast
What does progesterone do?
4
maintains endometrium
decreases contractility of the uterus
increases production of breast alveoli
increases maternal metabolism
What does human chorionic gonadotrophin do?
aids function of the corpus luteum (making sure continued supply of hormones to maintain pregnancy.
What does human placental lactogen do?
3
stimulates the maternal metabolism to supply nutrients for fetal growth
increases maternal resistance to insulin, and facilitates glucose transport across the placental membrane
stimulates breast development in preparation for lactation
4 metabolic functions of the placenta
excretion
nutrition
storage
respiration
fetal vs. maternal side of placenta
Fetal side:
smooth/shiny/bluishpurple, with veins branching out from the umbilical cord (like tree roots).
Maternal side:
rough/gritty/red, looks like a liver, contains 15-20 cotyledons, sometimes has grey/white calcium deposits
5 key features of fetal circulation
fetal oxygen needs are relatively low
the placenta is the organ of gas exchange
the fetal lungs are collapsed and fluid filled
the fetal brain and heart have the highest oxygen needs.
right-to-left shunting occurs through the ductus arteriosus and foramen ovale.
explain what is meant by the fetus exists in a state of relative hypoxemia
the PO2 of the fetus is only 30, which would cause hypoxia in the extra-uterine life.
PO2 of 30 sufficient inutero- zero hypoxia
O2 needs low because maternal system conducts many O2 using functions such as metabolism/digestion/thermoregulation, and zero ventilation is occurring.
effect of low PO2 on the ductus arteriousus/pulmonary arteries
Results in pulmonary vasoconstriction and causes dilation of the ductus arteriousus.
This pulmonary vasoconstriction leads to increased pulmonary vascular resistance, high pulmonary artery pressure, righttoleft shunting, and pulmonary hypoperfusion.
Does the R or L ventricle have more pressure?
The right ventricle — because it is pumping blood to collapsed, fluid-filled, vasoconstricted lungs — is experiencing higher pressure than the left ventricle which is pumping blood to the low pressure placenta.
*blood always flows in a path of least resistance
How does an increased PO2 impact adaptation
leads to pulmonary vasodilation
ductus arteriousus closes
L to R shunting d/t pressure change
What occurs with perinatal asyphyxia
blood shunted to heart/brain
all organs eventually become hypoxic
metabolic acidosis occurs
combo of acidosis/hypoxia results in cardiac/resp depression
low apgar score
effects of benzodiazepines during pregnany
risk of cleft lip/palate
effects of acutane during pregnancy
structural/sensory damage (neck&cranial region)
effects of aspirin during pregnancy
risk of abruption
effects of ibuprofen during pregnancy
can cause closure of the ductus arteriosus
effects of cocaine during pregnancy
urinary tract defects
effects of alcohol during pregnancy
skeletal abnormalities, heart defects, cleft palate, vision/hearing problems
causes of low birth weight
preterm
IUGR
two types of IUGR
hypoplastic: early in gestation, decrease in number of cells, small head/body, symmetrical
hypotrophic: later in gestation, decrease in size of cells, big head/small body, asymmetrical
SGA maternal causes
PIH (decreased blood flow to placenta)
malnutrition
maternal drug use (decreased blood flow to placenta)
SGA intrauterine causes:
placenta previa (decreased perfusion of nutrients d/t improper implantation of placenta)
small placenta (decreased perfusion)
teratogens (inhibit fetal growth)
SGA fetal causes
genetic defects resulting in decreased growth
preterm risk factors
maternal medical/past-preg hx
diabetes
HTN
renal disease
abortion
pre-term birth
uterine abnormalities
current preg hx multiple gestation placenta previa/abruption abd. surgery febrile illness
socioeconomic factors: single, poor, lack of education
Why are preterm infants more at risk for hypothermia?
less brown fat less subcutaneous tissue immature CNS-> inadequate temp. regulation fewer nutrient stores thinner skin
etc.
what does surfactant do?
prevents alveoli from collapsing
preterm infants have less surfactant resulting in atelectasis/increased work of breathing
F&E imbalances in preterm infants
increased total body water (80–85% of body weight).
increased extracellular water.
immature renal function.
++ Water losses d/t:
skin immaturity (evaporation)
increased body SA: body mass
why is absorption of protein/fat/carbs in the GI tract difficult for preterm infants
Feeding:
unable to coordinate sucking/ swallowing/ & breathing
impaired gag/cough reflexes
GI tract:
impaired cardiac sphincter-> gastroesophageal reflux
delayed gastric emptying
incompetent ileocecal valve
impaired rectosphincteric reflec.
Why is it difficult for preterm infants to deal with fluid overload/restriction
Overload: kidneys immature, so low GFR, unable to filter extra fluid
Restriction: immature kidneys cannot concentrate urine, water not easily reabsorbed
what are post-term infants at risk for?
asphyxia meccnium aspiration syndrome dysmaturity syndrome hypoglycemia polycythemia respiratory distress
pre-mature late preterm term post-term post mature
pre-mature: 42
post mature: >42 with S&S of placental insufficiency
fetal/maternal blood exchange
NO mixing of blood unless break in cell membranes
O2/nutrients/toxins go through “sieve” aka cell membranes that line the outside of the chorionic villi
Fetal circulation adaptations
organ of gas exchange lungs PO2 60-80 CO2 50 Low pulmonary resistance High systemic resistance L to R shunting/pressure gradient Forman ovale closes Ductus arteriosus closes
Fetal assessment
5
FHR fetal movement palpation fetal growth gestational age
When can women offer preconception education to child-bearing women?
Public health nurses
Anytime in contact with child-bearing women
Visiting school nurse i.e. sex education
Perinatal nurses i.e. healthy eating, lifestyle choices
low birth weight
1500-2499
very low if <1500 (100x mortality)
dietary consideration
folic acid/folate (0.4) reduces NTD
Iron (16-20) for RBC producion
Fish for omega3 (150g)
why are pregnant women more at risk for anemia
increase in circulating volume when pregnant, specifically plasma. Increase in RBC is not as great as plasma, and d/t low hgb/hct at risk for anemia.
optimal weight gain
6.8-18.2kg
or 0.4kg/week
recommendations for vegetarians
Increase calories
Take Vit B12
3 positive signs of pregnancy
Visualization of the fetus by ultrasound
auscultation of fetal heart tones
palpation or visualization of fetal movement.
4 signs of pregnancy often noted by women
Fatigue
nausea
breast tenderness or tingling
urinary frequency
When would supine hypotension occur?
2nd trimester
What is the couvade syndrome
When men experience S&S of pregnancy such as stress, weight gain, N&V
what does antenatal care include?
pre-conception counselling assessing risk factors assessment of fetus/complications educate birth care options
How often should parents have Dr. appointments?
seen first within 12w of LMP
then q4-6w until 30w
then q2-3w until 36
then qweek
Benefits of birth plans
communication tool for parents
good for when nurses switch during breaks/shift change
Disadvantages of birth plan
it is an ideal plan and if things dont go as planned it can cause dissapointment
Difference between breast feeding and breast milk feeding?
breast milk feeding does not promote bonding
does not stimulate release of hormones via skin-to-skin/suckling (Critical for maintaining breastfeeding)
when does lightening occur?
between weeks 38-40
fundus drops as fetus descends into the bony pelvis
AKA “the fetus is engaged”
operculum
mucus plug formed in cervix
when plug loosens, tiny blood vessels may become torn aka “bloody show”
How to confirm PROM
either a nitrazine test (for pH)
or ferning test (glass slide shows fern)
VE avoided d/t risk for infection/injury
management criteria for prom
afebrile
normal FHR
engaged fetus
<18h labour
True vs. False labour
contractions of true:
regular, increase in freq/intensity, continue in despite of comfort measure, more intense with activity
false: decrease with activity, decrease with comfort measures
cervix in true labour: softens/effaces/dialtes, bloody show, anterior position
false: soft, no effacement/dilation, posterior position
fetus in true labour: PP engaged
false labour: not well engaged
Parity
number of pregnancies carried to stage of fetal viability
fetal viability
capacity of fetus to live outside of uterus
22-25 weeks
Nullipara
Multipara
Primipara
not completed any pregnancies to stage of viablity
carried multiple pregnancies to stage of viability
carried one pregnancy to stage of viability
gravida
also can be Nul/Primi/Multi
of pregnancies
What is the presentation of a fetus?
part of fetus that enters pelvic inlet first
3 types: cephalic, breech, vertex
What is the position of a fetus?
relationship of the PP to the four quadrants of mothers pelvis
can be:
Left/Right
Occiput/Sacrum
Anterior/posterior/tranverse
i.e. LOA
