16-24 hours after LH surge

ক

ব্যাখ্যা

Explanation :
Explanation :
LH surge:
Sustained peak level of estrogen for 24-36 hours in the late follicular phase ➔ LH surge occurs from the anterior pituitary.
Ovulation approximately occurs 16-24 hours after the LH surge.
LH peak persists for about 24 hours.

The LH surge stimulates completion of reduction division of the oocyte and initiates luteinization of the granulosa cells, synthesis of progesterone and prostaglandins.

উত্তর

সঠিক উত্তর: খ

8-9 days post fertilization

খ

ব্যাখ্যা

Explanation :
Level of hCG at different periods of pregnancy:
hCG is produced by the syncytiotrophoblast of the placenta and secreted into the blood of both mother and fetus.
The plasma half-life of hCG is about 36 hours. By radioimmunoassay, it can be detected in the maternal serum or urine as early as 8-9 days postfertilization.
In the early pregnancy, the doubling time of hCG concentrations in plasma is 1.4-2 days.

The blood and urine values reach maximum levels ranging from 100 to 200 IU/mL between 60 and 70 days of pregnancy.

সঠিক উত্তর: খ

20 weeks

উত্তর

সঠিক উত্তর: খ

20 weeks

খ

ব্যাখ্যা

Explanation :
A term fetus shallows around 500 mL of amniotic fluid per day.
The meconium appears from 20th week and at term, it is distributed uniformly throughout the gut up to the rectum indicating the presence of intestinal peristalsis.
In intrauterine hypoxia (vagal stimulation), the anal sphincter is relaxed and the meconium may be voided into the liquor amnii.

Composition of the meconium:
It is chiefly composed of the waste products of the hepatic secretion.
It contains lanugo, hairs and epithelial cells from the fetal skin which are swallowed with the liquor amnii.
Mucus, exfoliated intestinal epithelium and intestinal juices are added to the content.
The greenish black color is due to the bile pigments, especially biliverdin.
Meconium is toxic to the respiratory system. It causes meconium aspiration syndrome.

It has got two phases:
(1) The propulsive or passive phase-starts from full dilatation up to the descent of the presenting part to the pelvic floor.
(2) The expulsive or active phase is distinguished by maternal bearing down efforts and ends with delivery of the baby.

Its average duration is 2 hours (WHO-3 hours) in primigravidae and 30 minutes (WHO-2 hours) in multiparae .

Preeclampsia

উত্তর

সঠিক উত্তর: ঘ

ঘ

ব্যাখ্যা

Explanation :
Importance of weight checking:
Single weight checking is of little value except to identify the overweight or underweight patient. Periodic and regular weight checking is of importance to detect abnormality.

♦ Rapid gain in weight of more than 0.5 kg (l lb) a week or more than 2 kg ( 4 lb) a month in later months of pregnancy may be the early manifestation of preeclampsia and need for careful supervision.

♦ Stationary or falling weight may suggest intrauterine growth retardation or intrauterine death of fetus.

সঠিক উত্তর: খ

Amino acid - Active transport

উত্তর

সঠিক উত্তর: খ

Amino acid - Active transport

খ

ব্যাখ্যা

Explanation :
Amino acids are transferred by active transport ( energy requiring transport) through enzymatic mechanism (ATPase).
Amino acid concentration is higher in the fetal blood than in the maternal blood. Some proteins (IgG), cross by the process of endocytosis.
Fetal proteins are synthesized from the transferred amino acids and the level is lower than in mother.
Glucose - Facilitated diffusion
Tryglyceride - Directly
Sodium, potassium - Simple diffusion

খ

ব্যাখ্যা

Explanation :
Sonography:
Complete mole appears as an echogenic mass with many anechoic cystitic spaces. There is neither the fetus nor the amniotic sac.

উত্তর

সঠিক উত্তর: খ

Faintly alkaline

খ

ব্যাখ্যা

Explanation :
PHYSICAL FEATURES of amniotic fluid -
The fluid is faintly alkaline with low specific gravity of 1.010.
It becomes highly hypotonic to maternal serum at term pregnancy.
An osmolarity of 250 mOsmol/L is suggestive of fetal maturity.
The amniotic fluid's osmolality falls with advancing gestation.
Color: In early pregnancy it is colorless, but near term it becomes pale straw colored due to the presence of exfoliated lanugo and epidermal cells from the fetal skin.
It may look turbid due to the presence of vernix caseosa.

Midline brownish black pigments from xiphisternum to symphyses pubis

উত্তর

সঠিক উত্তর: ক

Midline brownish black pigments from xiphisternum to symphyses pubis

ক

ব্যাখ্যা

Explanation :
Linea nigra: It is a brownish black pigmented area in the midline stretching from the xiphisternum to the symphysis pubis .
The pigmentary changes are probably due to melanocyte stimulating hormone from the anterior pituitary.
However, estrogen and progesterone may be related to it as similar changes are observed in women taking oral contraceptives.
The pigmentation disappears after delivery.

৩৩.

Progestin implant
গ
Combined oral contraceptive
ঘ
IUCD

সঠিক উত্তর: ঘ

IUCD

উত্তর

সঠিক উত্তর: ঘ

IUCD

ঘ

ব্যাখ্যা

Explanation :
Use of contraception:
IUD is contraindicated, because
of its frequent association of irregular vaginal bleeding.
This often confuses with choriocarcinoma. Risk of uterine perforation is also high.

Combined oral pills can be used after the hCG value has become normal.
Injection DMPA or progestin implant can be used safely
Barrier method of contraception can also be used.
Surgical sterilization is another alternative when she has completed her family.
