LEC 1: Assessment of the Pregnant Client Flashcards
Subjective Data: Health Hisotry
- Menstural history
- Gynecological hisotry
- Obstetrical history
- Current pregnancy
- Medical history
Health Hisotry Questions
- Family history
- Social history
- Review of systems
- Nutritional history
- Environment and hazards
What are presumptive changes?
- Subjective
- Symptoms experienced by the woman suggestive of pregnancy
- Can be caused by conditions other than preganncy such as:
- Urine tumours, polyps, infection, and pelvic congestion can cause elevated hCG levels, thus shape, size, and consistency
- Ovarian cancer, choriocarcinoma, hydatidiform mole can elevate hCG levels, thus pregnancy test are not 100% accurate
What are presumptive (time of occurance) sings?
- Fatigue (12 weeks)
- Breat tenderness (3 to 4 weeks)
- Nausea and vomiting (4 to 14 weeks)
- Amenorrhea (4 weeks)
- Urinary frequency (6 to 12 weeks)
- Hyperpigmentation of the skin (16 weeks)
- Fetal movment (quickening; 16 to 20 weeks)
- Uterine enlargment (7 to 12 weeks)
- Breast enlargment (6 weeks)
What are positive changes?
- Signs that are completely objective adn caused only by pregnancy
- Nomrally after 2 weeks after a missed period, enough subjective symptoms are present to determine pregnancy
- Pregnancy can be confirmed by identifying that fetus is growing in the uterus (positive sign)
- Ultrasound, palpating for fetal movements, and hearing fetal heartbeat
What are positive (time of occurrence) signs?
- Ultrasound verification of embryo or fetus (4 to 6 weeks)
- Fetal movement felt by experienced clinican (20 weeks)
- Auscultation of fetal heart tones via doppler (10 to 12 weeks)
What are probable changes?
- Objective
- Signs perceived by examiner
- Could be caused by conditions other than pregnancy
What are probable (time of occurrence) signs?
- Braxton hicks contractions (16 to 28 weeks)
- Positive pregnancy tests (4 to 12 weeks)
- Abdominal enlargment (14 weeks)
- Ballottement (16 to 28 weeks)
- Goodell’s sign (5 weeks)
- Chadwick’s sign (6 to 8 weeks)
- Hegar’s sign (6 to 12 weeks)
What is Naegele’s Rule?
- Used to determine the “due date”/ expected date of delivery (EDD)
- 1st day of last menstral period (LMP)
- Add 1 year
- Substract 3 months
- Add 7 days

-
A: Abortus
- Number of births <20 weeks
- Induced or spontaneous abortions
-
L: Living
- Number of living children
- NOT live births
- Twins count as one pregnancy/ birth but 2 infants

- 12 weeks before
What is the duration of the 1st trimester?
- 0 week to 13 weeks
What is the duration of the 2nd trimester?
- 14 weeks to 27 weeks
What is the duration of the 3rd trimester?
- 28 weeks to 40 weels
- or - 2 weeks
When is post-partum?
- After delivery
- Up to 6 weeks
Maternal Adaptations to Pregnancy
- Lab values and physical findings considered normal in non-pregnant state may not be normal for pregnant state, or vice versa
- Secondary mechanical changes exerted by growing fetus and enlarging uterus
- Change sin pregnancy affect all systems
Changes in the Body System: GI System
-
Mouth and Pharynx
- Gums become hyperemic, swollen, and friable and tend to bleed easily
- Saliva production increases
- Changes in taste and smell
-
Esophagus
- Decreased lower esophageal sphincter pressure and tine, which increases the risk of developing heartburn
-
Stomach
- Decreased tone and mobility which delayed gastric emptying time, which increases the risk of gastro-esophageal reflux and vomiting
- Morning sickness
- Decreased gastric acidity and histamine output, which improves symptoms of peptic ulcer disease.
- Decreased tone and mobility which delayed gastric emptying time, which increases the risk of gastro-esophageal reflux and vomiting
-
Intestines
-
Decreased intestinal tone motility with increased transit time, which increases risk of constipation and flatulence
- Decreased muscle tone related to progesterone and peristalsis leads to constipation/ delayed stomak emptying
-
Decreased intestinal tone motility with increased transit time, which increases risk of constipation and flatulence
Changes in the Body System: Cardiovascualr System
-
Blood Volume
- Marked increase in plasma (50%) and RBCs (25% to 33%) compared with non-pregnant values
- Causes hemodilution, which is reflected in a lower hematocrit and hemoglobin
- Increas in WBCs in 2nd and 3rd trimester
-
Cardiac Output (CO) and Hear Rate
- CO increases from 30% to 50% over the non-pregnant rate by the 32nd week of pregnancy
- The increas ein CO is associated with an increase in venous return and grater right ventricular output, especially in the left lateral position
- Heart rate increases by 10-15 beats/min between 14 and 20 weeks of gestation, and this increase persits to term
-
Blood Pressure
- Diastolic pressure decreases typically 10-15 mmHg to reach its lowest point by mid-pregnancy
-
Blood Components
- The number of RBCs increases throughout pregnancy to a level 25% to 33%
- Finbrin and plasma fibrinogen levels increase, along with various blood-clotting factors. These factors make pregnancy a hypercoagulable state
- Increase in blood clots
Vena Caval Sydrome
- Supine hypotension
- Decreased venous return due to venal caval compression in the supine position leads to supine hypotension and bradycardia
- 10% of pregnancies
- Symptoms mimic that of hypovolemic shock
- Reduced blood flow to placenta causes fetal hypoxia and distress
- Avoid supone positioning- Left lateral is optimal
Changes in the Body System: Respiratory System
- Enlargment of the uterus shofts the diaphragm up to 4cm above its usual position
- As muscles and cartilage in teh toracic region relax, the chest broadens, with conversion from abdominal breathing to thoracic breathing
- This leads to a 50% increase in aire volume per minute
- Tidal volume, or the volume of air inhaled, increases gradually by 30% to 40% as the preganacy progresses
- Increased oxygen by 15 to 20%
Changes in the Body System: Renal/ Urinary System
- The renal pelvis becomes dialted
- The ureters elongate, widen, and become more curved above the pelvic rim
- Bladder tone decreases and bladder capacity doubles by term
- GFR increases 40% to 60% during pregnancy
- Blood flow ot the kidneys increases by 50% to 80% as a result of the increase in cardiac output
Changes in the Body System: Musculoskeletal System
- Distention of the badomen with griwth of the fetus tilts the pelvis forward, shifting the center of gravity
- The woman compensates by developing an increased curvature (lordosis) of the spine
- Relacation and increased mobility of joints occur because of the hormones progesterone and relaxin, which lead to the characterisits “waddle gait”
Changes in the Body System: Integumentary System
- Hyperpigmentation of the skin occurs in the areola, genital skin, axilla, inner aspects of the thightsm abd kunea nigra
- Striae gravidarum (stretch markes), are irregluar reddish streaks that may appear on the badomen, breasts, and buttocks
- The skin in the middle of the abdomen may develop a pigmented line called linea nigram wich extends from the ambilicus to the pubic areas
- Melasma occurs in 45% to 70% of pregnant women. It is characterized by irregular, blotchy areas of pirgmentation on the face (cheeck, chin, and nose)
Changes in the System: Endocrine System
- Controls the integrity and duration of gestation by maintaining the corpus luteum vie hCG secretion
- Increased BMR
- Increased progesterone maintians pregnancy (relaxes smooth muscle)
- Increased estrogen enlarges uterus, breast, gentials
- Increased ocytocin at term leads to contractions, let-down relfect for lactation
- Change sin glucose regulation
