WEEK 1 Flashcards
What are the common medical disorders in pregnancy?
GHTN; GDM; Pre-eclampsia and eclampsia; Anemia
What are some of the complications that can occur when the pregnant women is experiences the above disorders?
IUGR; IUFD; Macrosomia; Neural tube defects in the fetus; Angina in the maternal
Differentiate between Pre-existing HTN, Gestational HTN, Pre-eclampsia, Eclampsia.
*Pre-existing HTN; BP greater or equal to 140/90 mmHg prior to 20 weeks GA, which persists for more than 7 weeks postpartum.
*Gestational HTN; BP greater or equal to 140/90 mmHg after taking 2 reading within 4-6hrs W/O proteinuria and other symptoms of organ failure after 20 weeks GA.
*Pre-eclampsia; new onset of HTN and presence of proteinuria/ symptoms of end organ failure typically after 20 weeks GA.
*Eclampsia; new onset, generalized seizures in a pregnant woman with pre-eclampsia/ GHTN. The seizure are not attributable to any other neurological condition.
What are the severe features that are associated with pre-eclampsia?
- Systolic BP greater or equal to 160mmHg; Diastolic BP greater or equal to 110mmHg on 2 occassions at least 4hrs apart
*HELLP Syndrome ( Hemolysis Elevated Liver enzymes Low Platelets)
*Symptoms of CNS dysfunction ( scotomata, somnolence, photophobia)
*Pulmonary edema
What are the risks of pre-eclampsia?
*Nulliparity; history of pre-eclampsia in previous pregnancy; molar pregnancy; pre-existing DM, HTN
What are the reasons of unintended pregnancies among women?
*limited access to contraceptives
*culture or religious opposition
*limited choice of family planning methods.
List the classes of contraceptives based on efficacy and give 2 examples under the listed classes.
*Most effective: sterilization( permanent) and Intrauterine Device( reversible)
*Effective: Oral contraceptives and vaginal ring
*Least effective: Condoms and Spermicide.
What are the factor affecting selection of a family planning method.
- Speed to return of fertility after method cessation
- Ability to withstand the side effects
*Culture and social barrier
Describe the general mechanism of action of the hormonal contraceptive methods.
*Thinning of the endometrial lining
* Thickening of the cervical mucus to keep sperm from reaching the egg.
*Suppresses ovulation by blocking LH and FSH surge
What is capacitation and state its importance.
The mechanisms employed by the oocyte to prevent polyspermy.
*Cortical Granule (CG) exocytosis: once sperm penetration occurs, intracellular release of calcium induces the membrane of the cortical granules to fuse with ooplasma and the CG contents are exposed to the perivitellline line.
*Modification of Zona Pellucida, by enzymes released from the cortical granules. Enzymes like proteinases change the ability of the zona pellucida to inhibit sperm acrosome reaction, thus preventing further sperm penetration.
“Coordinated cycle of stimulatory and inhibitory effects that results in release of a single mature oocyte from a pool of primordial oocytes”.

List the phases of blastocyst implantation
Apposition
Adhesion
Invasion
What is the function of the decidua
Protects the embryo from being attacked by maternal immune cells and provides nutritional support for the developing embryo prior to placenta formation.
