* Test 1 * Final N306 Exam 1 Study Guide (40 questions) Antepartum Assessments & Care 1. Reproductive Cycle & Fertilization https://www.youtube.com/watch?v=MLJTLAKFM3k A nurse is teaching a wom... an about her menstrual cycle. The nurse states that Proliferation of the endometrium is the most important change that happens before the secretory phase of the menstrual cycle. The clinic nurse knows that the part of the endometrial cycle occurring from ovulation to just prior to menses is known as the secretory phases occurs from the time of ovulation to the period just prior to menses, or approximately days 15 to 26.  The secretory phases occurs from the time of ovulation to the period just prior to menses, or approximately days 15 to 26.  Amniotic fluid first appears at about 3 weeks.  There are approximately 30 mL of amniotic fluid present at 10 weeks’ Reproductive Cycle: Menstrual Cycle 28 days MENSTRUAL CYCLE ● Ovarian Cycle: the maturation of the ova consisting of Follicular Phase - (from the 1st day of menstruation to 12-14 days) LH & FSH cause graafian follicle to mature producing Estrogen Ovulatory Phase - (begins when estrogen levels peak until oocyte released from graafian follicle) = OVULATION ^LH Luteal Phase - (begins after ovulation and lasts 14 days) ^ estrogen & progesterone If pregnant, know that the corpus luteum secretes estrogen & progesterone until placenta matures and assumes this function > If pregnant, corpus luteum will continue to secrete estrogen & progesterone until placenta matures > If NOT pregnant, corpus luteum degenerates = < in progesterone and beginning of menstruation ● Endometrial “Uterine” Cycle: changes in the endometrium of the uterus in response to the ovarian cycle Proliferative Phase - (occurs following menstruation ending with ovulation) endometrium preparing for implantation =more THICK & VASCULAR Secretory Phase - (after ovulation and ends with onset menstruation) = continues to THICKEN ^progesterone Menstrual Phase - sloughing off of the endometrium = PERIOD . Fertilization: “Conception” occurs when the sperm nucleus enters the nucleus of the oocyte within the outer third of the fallopian tube. ● The fertilized egg is then called a ZYGOTE and contains a diploid number of chromosomes = 46 gestation, and this amount increases to approximately 800 mL at 24 weeks’ gestation. After that time, the total fluid volume remains fairly stable until it begins to decrease slightly as the pregnancy reaches term. 2. Infertility > Both male & female need to be evaluated Infertility: the inability to conceive or maintain a pregnancy after 12 months of unprotected sexual intercourse ● 6 months for women older than 35 y.o > Causes ● 1/3 Male Factor ○ Endocrine - < in LH, FSH, Testosterone ○ Spermatogenesis - effects of gonadotoxins Gonadotoxins include: drugs, infections, systemic illness, heat exposure, pesticides and radiation to the pelvic region. ○ Sperm Antibodies - < in sperm motility ○ Sperm Transport - blocked transport ■ Vasectomy ■ Prostatectomy ■ Inguinal hernia ■ Absence of Vas Deferens ○ Disorders of Intercourse ■ Erectile Dysfunction ● 1/3 Female Factor ○ Ovulatory Dysfunction ■ Anovulation ■ Inconsistent Ovulation ○ Tubal & Pelvic Pathology ■ Damage to the Fallopian tubes ● ENDOMETRIOSIS ■ Uterine Fibroids: benign growth of uterine wall ○ Cervical Mucus Factor ■ Surgical surgeries: cryotherapy (TX cervical dysplasia) ■ Infection not allowing sperm to enter ● 1/3 Both Male and Female Factors > DX Testing: ● Screening for STI’s and STD’s ● Labs assessing levels of LH, FSH, TSH, testosterone ● Semen Analysis ● Assessment of Ovulatory Dysfunction ○ Daily Morning Body Basal Temp ○ Day 3 of menstrual cycle = FSH & estradiol test taken ○ Detecting LH surge 36hrs before ovulation ● Endometrial Biopsy at end of menstrual cycle ● Hysterosalpingogram radiological exam testing tubal problems ● Laparoscopy -visualize/inspect ovaries ● TX: ● Females: ○ Same lifestyle changes as men ○ Surgery to open tubes if abnormal ○ Myomectomy - removal of uterine fibroids ○ Antibiotics to TX infection ○ Medication stimulating egg production ■ CLOMIPHENE CITRATE : stimulates release of FSH & LH ● PO cycle Day 3-7 S/E: hot flashes, breast discomfort, headaches, insomnia TX: ● Males: ○ Hormonal Therapy ○ Lifestyle changes ■ Stress reduction, improved nutrition, smoking cessation, eliminating drugs ■ Corticosteroids to TX antibodies ■ Antibiotics to TX infection ■ Repair of inguinal hernia or obstruction A client is to take Clomiphene Citrate for infertility. Which of the following is the expected action of this medication? Stimulate release of FSH and LH A couple who has sought infertility counseling has been told that the man’s sperm count is very low. The nurse advises the couple that spermatogenesis is impaired when which of the following occur? The testes are overheated. A nurse working with an infertile couple has made the following nursing diagnosis: Sexual dysfunction related to decreased libido. Which of the following assessments is the likely reason for this diagnosis? The couple has established a set schedule for their sexual encounters. Couples who “schedule” intercourse often complain that their sexual relationship is unsatisfying. A couple is undergoing an infertility workup. The semen analysis indicates a decreased number of sperm and immature sperm. Which of the following factors can have a potential effect on sperm maturity? [Show More]
