Concepts for Lecture 1. Uterine Changes Enlargement due to hypertrophy (Figure 14.6) Thickening of the walls Increase in vascular and lymphatic system 2. Cervical Changes Development of mucous plug Goodells signsoftening Chadwicks signbluish-purple discoloration 3. Vaginal Changes Hypertrophy, increased vascularization, hyperplasia due to estrogen Increase in secretions, loosening of connective tissue 4. Breast Changes Glandular hyperplasia and hypertrophy Areolae darken, superficial veins prominent Striae may develop Colostrum is secreted 5. Respiratory Changes Tidal volume increases Oxygen consumption increases Breathing changes from abdominal to thoracic Vascular congestion of nasal mucosa 6. Cardiac Changes Blood volume increases 40% to 45% Decrease in systemic and pulmonary vascular resistance Increase in cardiac output 7. GI Changes Nausea and vomiting Hyperemia, softening and bleeding of gums Constipation Heartburn Hemorrhoids 8.Urinary Changes Pressure on bladder causes frequency Dilatation of kidneys and urine Increased GFR and renal plasma flow 9. Skin Changes Hyperpigmentation Striae Chloasma Vascular spider nevi Decreased hair growth Hyperactive sweat and sebaceous glands 10. Musculoskeletal Changes Pelvic joints relax Center of gravity changes Separation of rectus abdominus 11. Eye, Cognitive and Metabolic Changes Decreased intraocular pressure Thickening of cornea Reports of decreased attention, concentration, and memory Extra water, fat, and protein are stored Fats are more completely absorbed 12. Endocrine Changes T4 and BMR increase, TSH decreases Concentration of parathyroid hormone increases Thyrotropin and adrenotropin alter maternal metabolism Prolactin is responsible for lactation Secretion of oxytocin and vasopressin Increased aldosterone Learning Objective 2 Relate the physiologic and anatomic changes that occur in the body systems during pregnancy to the signs and symptoms that develop in the woman. Concepts for Lecture 1. Physical Symptoms of Pregnancy Braxton Hicks Increased vaginal discharge and risk of infection Leaking of colostrum Hyperventilation Nasal stuffiness and nosebleeds Lower extremity edema Postural hypotension Supine hypotensive syndrome (Figure 14.1) Nausea and vomiting Bleeding of gums Constipation and hemorrhoids Pruritus Urinary frequency Hyperpigmentation (Figure 14.2) Striae Vascular spider nevi Decreased rate of hair growth Heavy perspiration, night sweats, acne Waddling gait Backache Difficulty wearing contact lenses Learning Objective 3 Compare subjective (presumptive), objective (probable), and diagnostic (positive) changes of pregnancy. Concepts for Lecture 1. Presumptive Signs of Pregnancy Amenorrhea Nausea and vomiting Excessive fatigue Urinary frequency Breast changes Quickening 2. Probable Signs of Pregnancy Changes in the pelvic organs (Figures 14.4 and14.5) Enlargement of the abdomen Braxton Hicks contractions Abdominal striae Uterine souffle Changes in the pigmentation of the skin Ballottement Positive pregnancy tests 4. Positive Signs of Pregnancy Auscultation of fetal heartbeat Fetal movement Visualization of the fetus Learning Objective 4 Contrast the various types of pregnancy tests. Concepts for Lecture 1. A hemagglutination-inhibition test is a urine pregnancy test that uses hCG-sensitized red blood cells of sheep. The latex agglutination test is also a urine pregnancy test that is based on the fact that latex particle agglutination is inhibited in the presence of hCG. Avery accurate serum pregnancy test is b-subunit radioimmunoassay (RIA), which uses an antiserum with specificity for the b-subunit of hCG in blood plasma. It permits diagnosis of pregnancy a few days after implantation. Another serum pregnancy test is the immunoradiometric assay (IRMA), which uses a radioactive antibody to identify the presence of hCG in the serum.The enzyme-linked immunosorbent assay (ELISA) can detect hCG levels as early as 7 to 9 days after ovulation and conception. Another serum pregnancy test is the fluoroimmunoassay (FIA) that uses an antibody tagged with a fluorescent label to detect serum hCG. 2. Home pregnancy tests are quite sensitive and detect even low levels of hCG in urine. There is a low false-positive rate and a higher false-negative result. Learning Objective 5 Discuss the emotional and psychologic changes that commonly occur in a woman, her partner, and her family during pregnancy. Concepts for Lecture 1. Mothers Response to Pregnancy Ambivalence Acceptance Introversion Mood swings Changes in body image 2. Rubins (1984) Tasks of Pregnancy Ensuring safe passage through pregnancy, labor, and birth Seeking of acceptance of this child by others Seeking of commitment and acceptance of self as mother to the infant (binding-in) Learning to give of oneself on behalf of ones child 3. Fathers Response to Pregnancy Confused by partners mood changes Feels left out of pregnancy Resents attention given to the woman Resents changes in their relationship Needs to resolve conflicts about fathering Couvade 4. Family Response to Pregnancy Siblings Rivalry Fear of changing parent relationships Grandparents Closer relationship with expectant couple Increasingly supportive of couple Learning Objective 6 Summarize cultural factors that may influence a familys response to pregnancy. Concepts for Lecture 1. An important aspect of prenatal care is a cultural assessment in which the nurse needs to identify family beliefs, values, and behaviors that relate to pregnancy and childbearing. Information about ethnic groups, patterns of decision making, religious preferences, language, communication style, and common etiquette practices are important, as well as expectations of the healthcare system. Cultural Factors Identify beliefs, values, and behaviors Ethnic background Patterns of decision making Religious preferences, language, communication style Common etiquette practices Expectations of healthcare system     ;ty 9 M b   " c e & ( r t   * , J L z | ?AVX DFY[ceoqehKvmH sH jhKvUmHnHsHuhKv hKv5 hKv5CJ U :;Lt H y # 9 K L M b  n^`n`d#y# M N O c & ` r  * J z 1?V` 34DYco<e-Ci(`eg CEik(*AW!02eg})+=?]_ik~!+-Pf*,?ATVfh-/XZhKv hKv5a(ABW0e})=]i~+PQf`f*?Tft-Xh ;Prs`Zhj ;Pr=?LNZ\jly{%'}DFmo l ""c#d#e#g#h#j#k#m#n#p#q#r#s#t#u#v#w#x#hV+hVB*OJPJQJ_HmHnHphsHhZYjhZYU'hKvB*CJPJ_HmHnHphsH hKv5hKvJstu=LZjy%}Dm  F `F l m r"""""#=#c#d#f#g#i#j#l#m#o#p#q#r#s#t#u#v#`v#w#y#z#`x#y#z#'hKvB*CJPJ_HmHnHphsHhZY(/ =!"#$%` FnٝN>P6wJFIF &$/ #'),,,150*5&+,)  ),,),),)))),))),,)),),,),,),)),)))),))),)))),),))))v"9!1AaQ"q2r#3Rb !1Aa"23 ?@5\"׌yTgms4[){59Ӻ!u- {UIC$l'}x3[UyIhP7ͭX*RCZjSG\I7*1ٹ8, g#x=g47kg?Iھ(Ck^dkVHD̚3!~m^yKrZmH%('}6#="WRŻGmZ俿kfadejG]?U'HxM/!wjޚ›bJ,(Kao/X 6C+1VNvhzT"5y'{>{Ų:O''¿L7S͸|u 8wUzyKmPB4 H Q4fBWz}D@rnbYǕ~>ݢ}k43][3$ EEO XuE daE+ A2i` OGMkQs\rKNrñgyNu)z]q{z0θ[uN9pZ3$I:  i[*BfQb 1-MlNк^/u41tdQKCڬUN5 H5IiF,{.c2f`(bpC?{vwUuF\dSeyi2d*dɐ@ NormalE$$$d*$1$@& ]^`$a$-DM e568:;<7S*CJOJPJQJ@mH phsH tH _HH*>*KHEHaJfHq DAD Default Paragraph Fontdid  Table Normal.a44l44l (k(No ListO Header & FooterM$$$d*$1$@& ]^`$a$-DM $Y568:;<7S*CJOJPJQJ@mH phsH H*>*KHEHfHq O Body Text First Indent1E$$$xd*$1$@& ]^`$a$-DM Y568:;<7S*CJOJPJQJ@mH phsH H*>*KHEHfHq z> :;LtHy#9KLMb MNOc&`r*Jz1?V 34DYco<e - C i ( A B W  0 e }  ) = ] i ~   + P Q f *?Tft-Xh ;Prstu=LZjy%}DmFlmr=cdfgijlmopqrstuvw{00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000@00@00@00@000 eZx#z# (fsF v#z#y#|<R$}.%@8,@_b$N bȆՏp quR$5m'H[yUr- R$.d4K耩1C R$h L©9T?eIR$/}bGrpR$nٝN>P6w*>R$BIOWR$UMMlo R$KR$K R$M%@.R$U)r>HܿDbW@Z(    vA1.PSPSPSPSS`TS`TC"< C  ?z 8, *2"#8[^ ddffggijlmopx{33333333333ddffggijlmopx{sNtNuNvNwN^`o(EH.h^`ho(EH.^`o(EH.8^`8o(EH.^`o(EH.^`o(EH.p^`po(EH. ^` o(EH.@ ^`@ o(EH.^`o(EH.h^`ho(EH.^`o(EH.8^`8o(EH.^`o(EH.^`o(EH.p^`po(EH. ^` o(EH.@ ^`@ o(EH.^`o(EH.h^`ho(EH.^`o(EH.8^`8o(EH.^`o(EH.^`o(EH.p^`po(EH. ^` o(EH.@ ^`@ o(EH.^`o(EH.h^`ho(EH.^`o(EH.8^`8o(EH.^`o(EH.^`o(EH.p^`po(EH. ^` o(EH.@ ^`@ o(EH.^`o(EH.h^`ho(EH.^`o(EH.8^`8o(EH.^`o(EH.^`o(EH.p^`po(EH. ^` o(EH.@ ^`@ o(EH.VGVZY3jKvU]H#@cc`ccz@@UnknownGz Times New Roman5Symbol3& z Arialc0000҉0 Pro W3Times New Roman;& z Helvetica#hm&{&N 1N 1!WW#(]2 Chapter 13leifleif      Oh+'0`   ( 4@HPX Chapter 13leif Normal.dotleif3Microsoft Office Word@G@D,@9,N՜.+,0  hp  Denver School of Nursing1 W'  Chapter 13 Title  !"$%&'()*+,-./0123456789:;<=>@ABCDEFHIJKLMNQRoot Entry F@iJ,S1Table#6WordDocumentESummaryInformation(?DocumentSummaryInformation8GCompObjq  FMicrosoft Office Word Document MSWordDocWord.Document.89q
