High Risk Pregnancy (Notes)

The College of Nursing Nisi Dominus Frustra College of Nursing Maasin City, Souterhn Leyte Supplemental Review HIGH RISK PREGNANCY (Prepared by: Rhenier S.Ilado R.N) I.

IDENTIFYING AND/OR MONITORING HIGH RISK PREGNANCY a. Alpha-fetoprotein (AFP) enzyme blood test - elevated levels may identify the pregnant woman carrying a baby with neural tube defects (spina bifida and anencephaly) - if the AFP is elevated for two samples, it is followed by ultrasonography and amniocentesis for further confirmation done at 14 to 16 weeks gestation b. Ultrasonography 1. high-frequency sound wave testing - discerns multiple pregnancy, placental location and gestational age by measurement of bi-parietal diameters a. visualization during first 20 weeks of gestation is improved if the bladder is full; a full bladder is not necessary after 20 weeks gestation b. a level II sonogram may be performed to assess formation of organs c. nursing considerations: 1. encourage fluid and refrain from voiding before the test c. Chorionic villi sampling (CVS): - supplies some data as amniocentesis but can be done after 10 weeks 1. aspiration of villi done during the eighth to twelfth week of pregnancy 2. nursing considerations: a. instruct to drink fluid so that bladder is full b. after test, monitor for uterine cont5ractions, vaginal discharge and teach to observe for signs of infection d. Amniocentesis - aspiration of amniotic fluid used to detect sex, chromosomal or biochemical defects, fetal age, L/S ratio (2/1 ratio indicates lung maturity), increased bilirubin level associated with Rh disease, and phosphatidylglycerol (PG), which appears in amniotic fluid after thirty-fifth week, indicating fetal lung maturity. 1. test done with sonogram; usually after 12 to 15 weeks of gestation 2. nursing considerations: a. have client void b. after test monitor for uterine contractions, vaginal discharge c. teach to observe for signs of infection d. encourage rest e. Non-tress test (NST) - done to observe for accelerations of FHR in response to fetal movement over a 30 to 40 minute period 1. Classification of results: a. a test is negative or reactive if: (1) baseline FHR is 120 to 160 (2) there are two accelerations in 10 minutes, each increasing the FHR by 15 and lasting 15 seconds

(3) the tracing shows variability of 10 or more beats per minute b. test is positive or non-reactive if the three criteria are not met 2. Nursing considerations: a. fasting is not necessary b. observe the fetal monitor c. explain test to decreased anxiety d. evaluate response to procedure f. Contraction stress test (CST): - to demonstrate whether a healthy fetus can withstand a decreased oxygen supply during the stress of a contraction produced by exogenous oxytocin (pitocin) or stimulation of nipples manually or by moist heat; if late decelerations appear, the fetus may be compromised because of uteroplacental insufficiency 1. Classification of results a. negative: no late decelerations with a minimum of three contractions in 10 minutes; indicates that the fetus has good chance of surviving labor b. positive: persistent and late decelerations occurring with more than half the contractions; indicates need for considering premature intervention c. suspicious: late decelerations occurring in less than half of uterine contractions; test should be repeated in 24 hours 2. Nursing considerations: a. void before test b. monitor fetal heart rate for 30 minutes before test c. monitor ,mother after test to observe for possible initiation of labor

d. evaluate response to procedure

g. Biophysical profile (BPP): - assess breathing movements, body movements, tone, amniotic fluid volume and FHR reactivity (NST) - a score of 2 is assigned to each finding, with a score of 8 to 10 indicating a healthy fetus 1. used for fetus that may have intrauterine compromise 2. nursing considerations: a. provide emotional support b. evaluate response to procedure h. Maternal assessment of fetal activity: - need to contact physician or nurse midwife when there are fewer than 10 fetal movements in a 12 hour period. - fewer than three fetal movements in an 8 hour period, or no fetal movements in he morning 1. used to determine viability of fetus 2. nursing considerations: a. teach how to record and report movements

functional or therapeutic classification of heart disease during pregnancy 1. Class I: no limitation of physical activity; no symptoms of cardiac insufficiency or angina 2. Class II: slight limitation of physical activity; may experience excessive fatigue, palpitation, angina or dyspnea; slight limitations as indicated 3. Class III: moderate to marked limitation of physical activity; dyspnea, angina and fatigue occur with slight activity and bed rest is indicated during most of pregnancy 4. Class IV: marked limitation of physical activity; angina, dyspnea and discomfort occur at rest; pregnancy should be avoided; indication for termination of pregnancy Nursing care of Pregnant Clients with Heart Disease: A. Assessment 1. prenatal period: vital signs, weight gain, dietary patterns, emotional outlook, knowledge about self-care, sign of heart failure, stress factors such as work, household duties 2. intra-partal period: vital signs (heart rate will increase), respiratory changes (dyspnea, coughing, crackles); FHR patterns 3. Post-partal period: signs of heart failure or hemorrhage related to fluid shifts; intake and output B.

Nursing Diagnosis 1. activity intolerance related to increased cardiac workload 2. anxiety related to unknown course of pregnancy, possible loss of fetus and inability to perform role responsibilities C.

Implementation 1. Prenatal period: a. teach importance of rest and avoidance of stress b. instruct regarding use of elastic stockings and periodic elevation of legs c. teach appropriate dietary intake: adequate calories to ensure appropriate, but not excessive, weight gain, limited, not restricted, salt intake d. administer medications as ordered: heparin, furosemide (Lasix), digitalis, betablockers (inderal) e. monitor for signs of heart failure, such as respiratory distress and tachycardia 2. Intra-partal period: a. encourage mother to remain in semi-fowlers or left lateral position position b. provide continuous cardiac and fetal monitoring c. assist with forceps birth in second stage of labor to avoid work of pushing 3. Post-partal period: most critical time because of increased circulating blood volume after birth of placenta a. institute early ambulation schedule; apply elastic stockings b. monitor for signs of heart failure such as respiratory distress and tachycardia

c. monitor for heart rate: accelerated heart rate of mother in latter half of pregnancy puts extra workload on her heart d. provide for adequate rest; the increase in oxygen consumption with contractions during labor makes length of labor a significant factor e. provide close supervision: sudden tachycardia during birth or sudden bradycardia and normal increase in cardiac output following birth may cause cardiac arrest D.

Evaluation 1. delivers healthy infant 2. maintains cardiac status within acceptable limits

2. DIABETES MELLITUS Data base: A. normal physiology of pregnancy that affects woman with diabetes 1. vomiting during pregnancy, especially in the first trimester, decreases carbohydrate intake with resulting acidosis and insulin dosage adjustment 2. human placental lactogen decreases insulin response in pregnant diabetics and maternal sparing of glucose: this leads to a greater need for insulin, although insulin increases, resistance to insulin also increases because of the presence of placental lactogen. Thus more exogenous insulin is required to maintain normal blood glucose, especially in latter part of pregnancy 3. normal lowered renal threshold for glucose can result in glusosuria 4. muscular activity during labor depletes glycogen; therefore carbohydrate intake must be increased B.

Diabetes mellitus during pregnancy may be: 1. pre-gestational a. type 1 diabetes - complications include retinopathy, neuropathy and coronary artery disease b. type II diabetes - complications include retinopathy, neuropathy and coronary artery disease 2. gestational a. diet controlled

C.
