D. Late secretory
A. Anovulatory cycle
Note: Although taken past-expected ovulatory day, which is day 14, the endometrial biopsy doesn’t show any secretory changes; rather it shows proliferative changes due to unopposed estrogen effect, which means ovulation didn’t happen “anovulatory cycle”.
Choice C “proliferative endometrium” is not appropriate since it doesn’t denote the pathology.

Note: “Deep cervical lymph nodes” is the correct answer because the question said “eventually” (According to Dr. Waleed Renno).
The doctor told me that he edited this question in the bank and put “diaphragmatic LNs” instead of “deep cervical” so only 1 correct answer remained (central axillary LNs).

However, hCG peaks in the 10th week and then declines.

A 40 year-old lady, who is currently 10-week pregnant, reported that she had 4 C-sections previously at 38 weeks of gestation. One of her children died at the age of 3 weeks because of a congenital disease. She also reported having 2 previous miscarriages. What is the parity code for this lady?
A. G6 P4+0+2+4
B. G6 P4+0+2+3
C. G7 P4+0+2+4
D. G7 P4+0+2+3
C. G7 P4+0+2+4
Note: You have to include the current pregnancy in the G code (4 pregnancies ended in C-sections at term + 2 pregnancies ended in miscarriage + 1 current pregnancy = 7).
There is lack of consensus regarding the “L” in the parity code.
L means “live births” not “living children” so the baby who has died should be included in the parity code (This is the coding system that Dr. Jehad follows).
Many doctors in the hospitals follow a different coding system. They told the students that “L” means “living children” so they chose “D” instead of “C”. For this reason, Dr. Jehad removed this question when we informed her. SO ALWAYS STICK TO WHAT SHE SAYS!
