Which of the following statements are true about teratogens? Select all that apply.00000O The greater the exposure, the greater the impact from teratogens.O Illicit drugs are teratogenic; prescription drugs are safe.Teratogenic impact can be greatly reduced by education and minimizing exposure.Major defects from teratogenic exposure will often result in a spontaneous abortion.The most vulnerable time for exposure and an anomaly to occur is between weeks 16 and 32.

Which of the following statement about the principles of teratology is NOT true? O a. Susceptibility to teratogenesis depends on the genotype of the conceptus. O b. The maternal genome plays an important role with respect to drug metabolism, resistance to infection, and other processes that affect the conceptus Oc.

Susceptibility to teratogenesis depends on the development stage at the time of exposure O e. Manifestations of abnormal development include death, malformation, growth retardation, and function disorders.
Identify 3 effects of progesterone on pregnancy. Select one or more: O a. This causes the uterus to remain contracted after delivery to reduce blood loss from the placental site O b. This is produced when the ovarian follicle that encloses the developing egg forms a structure called the corpus luteum O c. This decreases bladder tone leading to an increased risk of urinary infection O d. This prepares the body for pregnancy. It acts as an appetite stimulant Identify 1 effect of the hormone vasopressin in pregnancy. Select one: O a. This has an important compensatory mechanism for restoring blood pressure in hypovolaemic shock such as that which occurs during haemorrhage O b.

Hypothyroidism during pregnancy causes some defects in growing babies. State any two of them.
Identify 3 effects of Human Placental Lactogen (HPL) in pregnancy. Select one or more: O a. This helps to ensure the endometrium is ready to receive the implantation of the embryo O b. Higher levels of this are noted with multiple gestations O c. Reduces maternal insulin sensitivity leading to an increase in maternal blood glucose levels O d.

Make a Partograph in the following Case scenario Rose is a 25 year old G2 P1 on her 39th week of pregnancy. Rose came in the labor room at 8:00 am on active labor. Vital signs : BP- 120/ 85 , Pulse = 85, RR 25 Temperature = 37.2 C,. Fundic height = 37 cm. Nurse Mark had done the vaginal exam and showed 4 cm cervical dilatation. Fetal heart beat taken by Doppler was 156 beats / min. CTG was ordered and Rose was attached to the machine, Tracing showed several decelerations at each contraction, At 12 noon, Nurse Mark checked the vital signs and recorded the following : BP= 135/85, pulse 90 , RR = 25 Temperature 37.4 C, IE = 8 cm dilatation,. While Nurse Mark was preparing Rose for delivery, Dr. Ben the Obstetrician ,came and reminded the nurse to prepare standby 10 units of syntocinon to be incorporated in 500 ml of D5 LR post delivery. The Physician likewise ordered a standby 50 mg of Tramadol IM and this will be given after delivery. After 30 mins, Bag of water burst and a…
