Regarding amniotic fluid volume:
Your Answer: Maybe predicted by ultrasound
Explanation:Amniotic fluid can be measured with the help of ultrasound to gauge the amniotic fluid index. The normal value ranges between 8-18.
Amniocentesis is a procedure by which amniotic fluid is removed. In rhesus disease, it appears yellow due to raised bilirubin levels. -

Which one of the following features indicates fetal asphyxia?
Your Answer: Type II (late) decelerations with tachycardia
Explanation:A type II deceleration is due to placental insufficiency which can result in fetal distress and asphyxia. The fetal heart rate is lowest at the start of the contraction and returns to normal after the contraction is complete.

The resting pulse in pregnancy is:
Your Answer: Increased by 10 to 15 bpm
Explanation:During pregnancy cardiac output increases by 30 to 50%. As a result, the resting pulse speeds up from a normal of about 70 bpm to 80 or 90 bpm.

All of the following statements regarding human chorionic gonadotrophin are true except::
Your Answer: It's level doubles every 48 hours in ectopic pregnancy
Explanation:In normal pregnancy the levels of hCG doubles after every 48-72 hours but in case of ectopic pregnancy the levels of hCG are lower than the normal. It is produced by the placenta and its main role is nourishment of the egg after implantation. Its levels reached a peak at 8-10 weeks of pregnancy and after that the levels decreases for the remainder of pregnancy. In hydatiform mole and trophoblastic diseases its the main hormone for diagnosis of the disease because the levels are highly elevated.

During wound healing the clotting cascade is activated. Which of the following activates the extrinsic pathway?
Your Answer: Tissue Factor
Explanation:The extrinsic pathway is activated by the tissue factor, which converts factor VII to VIIa which later on converts factors X and II to their activated form finally leading to the conversion of fibrinogen to fibrin fibres.

Luteal phase deficiency is characterised by:
Your Answer: Associated with delayed menstruation
Correct Answer: Has inadequate luteal progesterone production

What is the most common cause of hypercalcaemia?
Your Answer: Primary hyperparathyroidism
Explanation:Primary hyperparathyroidism is the most common cause of hypercalcemia. It is usually caused by a tumour of the parathyroid gland. Symptoms are related to increased calcium levels which can cause kidney stones, abdominal groans, psychiatric overtones and bones disease such as osteoporosis,osteomalacia and arthritis.

Which of the following statements is true regarding heart rate in pregnancy?
Your Answer: Heart rate increases by 15 beats per minute
Explanation:During the first 12 weeks of pregnancy, cardiac output increases by about 30-50%. To maintain this increase, systemic vascular resistance decreases by 20-30%, while stroke volume and the heart rate increase by 25-30% and 15 beats per minute respectively.

Regarding heart rate in pregnancy which of the following statements is true?
Your Answer: Heart rate increases by 15 beats per minute
Explanation:The following cardiovascular changes occur during pregnancy:
– Blood volume slowly increases by 40-50%
– Heart rate rises by 15 beats/min above baseline
– Stroke volume increases by 25-30%
– Cardiac output increases by approximately 30-50%
– Systemic vascular resistance (SVR) decreases by 20-30%
– Diastolic blood pressure consequently decreases between 12 and 26 weeks but increases again to pre-pregnancy levels by 36 weeks.
As most of the changes occur in the first 12 weeks of gestation cardiac problems are likely to present in early pregnancy -
