• Faintness
• Food cravings
• Heartburn
• Constipation, flatulence
• Varicose veins
3rd • SOB and dyspnea (60% of
women)

swings, mixed feelings, anxiety
• Urinary frequency and urgency
return
, • Perineal discomfort and
Pressure
• Braxton Hicks contraction
• Leg cramps
• Ankle edema (non-pitting) to
lower extremities
Physiologic changes of pregnancy
Cardiac changes during pregnancy
Expected changes Cardiac Alterations or warnings Interventions
HR: increases by 15-20 Increase of BP 20 over baseline Monitor VS
BP: slight to no paired with proteinuria NST
decrease Increase in BP paired with other Fetal monitoring
BV: increases by 1200- signs of cardiovascular issue Assess for signs of
1500 Harsh murmur preeclampsia
CO: increases by 30-50
May experience
palpitations
Soft murmur
Dietary recommendations for pregnancy
Nutrition
Folic Acid Protein
• Folate/folic acid – preconception to 60-70g/day
decrease risk of NTD Needed throughout pregnancy
• 0.4mg po daily antepartum 4 weeks- brainstem dev
• 0.6 mg po daily during pregnancy Inadequate: neurologic damage
Sources: spinach, broccoli, whole grains,
green leafy vegetables, peanuts,organ
meats
Iron Calcium
Last trimester important: fetus must have 3- 1000mg in adults
6mo supply in liver 1300mg if <19yo
Usually a supplement is given, not in first 240ml or 1 cup milk or yogurt= 300mg
trimester tho Especially in 3rd trimester
Lean meats, green leafy veg, eggs, Lactose intolerant moms require a
shellfish, dried fruits, molasses, whole supplement
grains
Vit C increases absorption
, Substance use – alcohol, smoking, opiods, neonatal abstinence
Teratogens: environmental substances/exposures resulting in functional or structural
disability, mental development. Greatest effect: 16-60 days. Drugs. Chemicals, infections,
radiation, maternal conditions such as diabetes, maternal PKU
Alcohol: growth restriction, cognitive impairment, microcephaly, malformation of the face
and trunk
Cocaine: cardiac and CNS anomalies, growth restriction, placental abruption, placental
restriction
Nicotine: LBW, early labor
Opioid: Neonatal absence
Stages of Labor- include physiologic changes, expected patient responses, interventions
