Health Promotion Guidelines Across Lifespan
Intra-uterine
Oxygen
- To meet the fetal demands for oxygen, the pregnant mother gradually increases her normal blood flow by about one-third, peaking at about 8 months.
- Respiratory rate and cardiac output increase significantly during this period.
- Feta circulation travels from the placenta through umbilical arteries, which caries deoxygenated blood away from the fetus.
Nutrition and Fluids
- The fetus obtains nourishment from the placental circulation and by swallowing amniotic fluid.
- Nutritional needs are met when the mother eats a well-balanced diet containing sufficient calories and nutrients to meet both her needs and those of the fetus.
- Adequate folic acid, one of the B vitamins, is important in order to prevent neural tube defects
- Folic rich foods are green leafy vegetables, oranges, dried beans and suggest she take a vitamin supplement that contain folic acid.
Rest and Activity
- The fetus sleeps most of the time and develops a pattern of sleep and wakefulness that usually persist after birth.
- Fetal activity can be felt by the mother at about the fifth lunar month of pregnancy
Elimination
- Fetal feces are formed in the intestines from swallowed amniotic fluid throughout the pregnancy, but are normally not excreted until after birth.
- Urine normally is excreted into the amniotic fluid when the kidneys mature (16 to 20 weeks).
Temperature Maintenance
- Amniotic fluid usually provides a safe and comfortable temperature for the fetus.
- Significant changes in the maternal temperature can alter the temperature of the amniotic fluid and the fetus.
- Significant alter in temperature increases due to illness, hot whirlpool baths, or saunas may result in birth defects.
- In the last weeks of gestation, the fetus develops subcutaneous fatty tissue stores that will help maintain body temperature at birth.
Safety
- The body systems form during the embryonic period. As a result, the embryo is particularly vulnerable to damage from teratogen, which is anything that adversely affects normal cellular development in the embryo or fetus.
- It is important for the nurse to inquire about possible pregnancy when giving medications that are known teratogens and also ask when the woman is scheduled for tests that involve radiography (x-ray).
- Smoking, alcohol, and drugs can affect the environment for the fetus. Smoking has been associated with preterm labor, spontaneous abortion, low-birth weight infants, and sudden infant death syndrome and learning disorders.
- Fetal alcohol syndrome (FAS), a result of impaired mitochondrial development, leads to microcephaly, mental retardation, learning disorders, and other central nervous system defects.
Infants
Health Examinations
- Screening of newborns for hearing loss; follow-up at 3 months and early intervention by 6 months if appropriate
- At 2 weeks and at 2,4,6, and 12 months
Protective Measures
- Immunizations: diptheria,tetanus, acellular pertussis (DTaP), inactivated poliovirus vaccine (IVP), pneumococcal, measles-mumps-rubella (MMR), Haemophilus influenzae type B (HIB), hepatitis B (HepB), varicella and influenza vaccines as recommended
- Fluoride supplements if there is adequate water fluoridation (less than 0.7 part per million)
- Screening for tuberculosis
- Screening for phenylketonuria (PKU) and other metabolic conditions
- Prompt attention for illnesses
- Appropriate skin hygiene and clothing
