Maternity Nursing Q 138
Which of the following statements is TRUE of conception?
A. Within 2-4 hours after intercourse, conception is possible in a fertile woman.
B. Generally, fertilization is possible 4 days after ovulation.
C. Conception is possible during menstruation in a long menstrual cycle.
D. To avoid conception, intercourse must be avoided 5 days before and 3 days after menstruation.
Correct Answer: A. Within 2-4 hours after intercourse conception is possible in a fertile woman.
The sperms when deposited near the cervical os will be able to reach the fallopian tubes within 4 hours. If the woman has just ovulated (within 24hours after the rupture of the Graafian follicle), fertilization is possible.
Option B: Following ovulation, the egg is capable of fertilization for only 12 to 24 hours. Contact between the egg and sperm is random. Once the egg arrives at a specific portion of the tube, called the ampullary-isthmic junction, it rests for another 30 hours.
Option C: Conception during menstrual period is unlikely because the ovulation time is several days away, decreasing any chances of getting pregnant during this time. However, there are exceptions. This applies to women who have a typical 28 to 30 day or longer cycle. If the woman has a shorter cycle, that means that she may ovulate earlier in the cycle.
Option D: The likelihood of getting pregnant right before menstruation is extremely low. For women with a typical 28- to 30-day cycle or longer and their cycles are regular, it is fairly safe to say that ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.
