The body experiences many anatomical/physiologic changes during pregnancy. Findings in a physical assessment that would be considered abnormal in the nonpregnant client may be a result of pregnancy and not an abnormal state.
In this chapter, the physical changes that occur in a woman as a result of pregnancy are identified as normal variations. Changes that are not a result of pregnancy or that represent an abnormal state during pregnancy are identified as deviations from normal.
Prenatal maternal assessment
1. Subjective data: Focus questions
2. Objective data: Perform a general physical survey
Subjective data: Focus questions
Past pregnancies
Current pregnancy
Objective data: Perform a general physical survey
Age
Weight
Blood pressure
Pulse
Behavior
Skin color
Head and neck
Cardiovascular system
Respiratory system
Breast
Gastrointestinal system
Genitourinary-reproductive system
Musculoskeletal system
Neurologic system
Ideal childbearing age
16-35 years
Advanced maternal age
Increases risk of genetic abnormalities such as Down Syndrome
Increased risk to mother and baby with age extremes
Average total weight gain
25-35 lb
First trimester weight gain
4 lb
Second trimester weight gain
11 lb (1lb/wk)
Third trimester weight gain
11 lb (1lb/wk)
Pre-pregnant weight
Sudden weight gain seen in pregnancy-induced hypertension (PIH)
Weight loss or failure to gain weight
Normal blood pressure range
90-130/60-89 mmHg
Blood pressure changes during pregnancy
Falls during second trimester, pre-pregnant level first and third trimesters
Abnormal blood pressure
>140/90 mmHg or increase of 30 mmHg above baseline systolic or 15mmHg above baseline diastolic taken with client in side-lying position
Increased levels are seen with PIH
Normal pulse range
60-90 bpm: may increase 10-15 bpm higher than pre-pregnant levels
Abnormal pulse
Irregularities: persistently <60 or >100 bpm at rest
Behavior changes during pregnancy
First trimester: Tired, ambivalent
Second trimester: Introspective, energetic
Third trimester: Restless, preparing for baby, labile moods
Abnormal behavior
Denial of pregnancy, withdrawal, depression, psychosis
Normal skin changes
Linea nigra, striae gravidarum, chloasma
Abnormal skin changes
Pale, yellowish changes in color of the skin with liver diseases
Head and neck changes
Nasal stuffiness, nosebleeds
Slight enlargement of thyroid
Blurred vision and visual spots are symptoms of PIH
Abnormal head and neck changes
Nodules or marked enlargement, asymmetry of thyroid gland as seen with thyroid disease
Cardiovascular changes
Short systolic blowing murmurs
Blood volume increases throughout pregnancy, peaks at 32-34 weeks, reaching 30-50% above prepregnancy levels
Abnormal cardiovascular changes
Progressive dyspnea, palpitations, markedly decreased activity tolerance may be seen with cardiac diseases
Peripheral vascular changes
Late pregnancy: dependent edema, varicose veins, supine hypotension
Abnormal peripheral vascular changes
Perineal varicosities; calf pain may be related to deep vein thrombosis; generalized edema; diminished pedal pulses
Respiratory changes
Increased anteroposterior diameter, thoracic breathing, slight hyperventilation, shortness of breath in late pregnancy
Abnormal respiratory changes
Dyspnea may be seen in patients with cardiac and/or lung diseases such as asthma
Breast changes
Increased size and nodularity, tenderness, prominent vascularization, darkening of nipples and areola, colostrum in third trimester
Abnormal breast changes
Localized redness: localized pain and warmth; erythemic streaks are commonly seen with mastitis; inverted nipples may cause difficulty for breast-feeding infants
Gastrointestinal changes
Nausea and Vomiting, increased saliva, heartburn, bloating, constipation
Abnormal gastrointestinal changes
Severe epigastric pain is seen with PIH; severe nausea & vomiting may be seen during the first trimester with hyperemesis gravidarum
Genitourinary-reproductive changes
Urinary frequency in first and third trimesters, increased pigmentation of vulva and vagina, increased vaginal discharge
