Reproduction And Management Of Fertility And Infertility Concept 21 And Chap 31 Flashcards
Reproduction
Process by which human beings produce a new individual. Sexual intercourse between a man and woman may result in the conception of a child.
Formation of reproductive cells
Formation of germ cells. Gametogenisis is the formation and development of germ cells, oocytes, spermatocytes. Meiosis occurs (23 chromosomes)
Oogensis
Process of egg formation begins during fetal life and is known as oogenesis. Only 400-500n ovum will mature enough to reproduce.
Spermatogensis
Germ cell to a sperm cell. Begins at puberty
Fertilization
Sperm is ejaculatedd—> travel through cervix into uterus—>Fallopian tubes—> ovum—>cortical reaction with sperm and ovum—>zygote forms
Implantation
Cavity is formed in the morula after 4 days after fertilization. Becomes a blastocysts and floats freely within the uterus for 2 days—>form trophoblast and an inner layer embryoblast—.9.5 days layer completely in endometrium
Embryonic period
Weeks 3-8 after conception
Highly sensitive period
Fetal period
Represents the final stage of development beginning on the ninth week after fertilization until birth.
Populations at risk for consequences
Adolescent population: impaired nutrition, anemia, infections, depression, social isolation, preeclampsia. Protracted labor, caphalopelvic disproportion, premature brith, and C-section.
Individual risk factors include
Biophysical factors (altered or mutated genes) Psychosocial factors (smoking, excessive caffeine intake, etc) Sociodemographic factors (low income, low prenatal care) Environmental factors (pollution, radiation, infections)
History assessment
Sexual history, contraceptive history, surgical history, alterations in pelvic support, papanicolaou history, and menstrual history
Diagnostic tests assessment first trimester
Pregnancy test CBC Blood type Rebuild titer HepB Syphilis test HIV test Urinalysis Pap test Gonorrhea and chlamydia Nuchal translucency Amniocentesis Emotional well-being
Diagnostic tests second trimester
CBC 1 hour glucose tolerance test MSAFP screening Amniocentesis Emotional well being
Diagnostic tests third trimester
Group B strep testing
Screening and diagnostic ultrasound
Emotional well-being
Analgesics (actaminophen)
Pain
Antibiotics (ampicillin, clindamycin, cefazolin, metronidazole, gentamicin, penicillin, erythromycin)
Infections
Antidepressants (sertraline, escitalopram)
Mood disorders
Antiemetic (promethazine, ondansetron)
Nausea
Folic acid
Neural tube defect prevention
Flu vaccine
