Correct Answer is D
Explanation
Choice A: 28 weeks' gestation is too early to screen for group B streptococcus infection. Group B streptococcus (GBS) is a type of bacteria that can cause serious infections in newborns if transmitted from the mother during labor and delivery. The optimal time to screen for GBS is between 35 and 37 weeks' gestation.
Choice B: 32 weeks' gestation is also too early to screen for GBS infection. Screening at this time may not reflect the true colonization status of the mother at the time of delivery, as GBS can be transient or intermittent.
Choice C: 16 weeks' gestation is much too early to screen for GBS infection. Screening at this time has no clinical value, as GBS colonization can change throughout pregnancy.
Choice D: 36 weeks' gestation is the appropriate time to screen for GBS infection. Screening at this time can identify mothers who are colonized with GBS and who need intrapartum antibiotic prophylaxis to prevent neonatal sepsis, pneumonia, and meningitis.
Correct Answer is A
Explanation
Choice A Reason: This is correct because recurrent pelvic infections, such as pelvic inflammatory disease (PID), can cause scarring and inflammation of the fallopian tubes, which can impair the normal movement of the fertilized egg to the uterus. This can increase the risk of ectopic pregnancy, which is a life-threatening condition where the fertilized egg implants outside the uterine cavity, usually in the fallopian tube.
Choice B Reason: This is incorrect because ovarian cysts are fluid-filled sacs that develop in or on the ovaries. They are usually benign and do not affect fertility or pregnancy. However, some types of ovarian cysts, such as endometriomas or dermoid cysts, may require surgery to remove them, which can cause damage to the ovaries or fallopian tubes and increase the risk of ectopic pregnancy.
Choice C Reason: This is incorrect because use of oral contraceptives for 8 years is not a risk factor for ectopic pregnancy. In fact, oral contraceptives can reduce the risk of ectopic pregnancy by preventing ovulation and fertilization. However, if a woman becomes pregnant while taking oral contraceptives, she should stop taking them and consult her doctor, as they may have adverse effects on the developing fetus.
Choice D Reason: This is incorrect because heavy, irregular periods are not a risk factor for ectopic pregnancy. They may indicate other conditions such as hormonal imbalance, uterine fibroids, polycystic ovary syndrome (PCOS), or endometriosis, which can affect fertility or pregnancy, but not necessarily cause ectopic pregnancy.
