A nurse is caring for a client who is pregnant for the fourth time. The client delivered two full- term newborns and had one spontaneous abortion at 10 weeks of gestation. The nurse should document the client's obstetrical history as which of the following?

Choice A rationale:

The nurse should discontinue the oxytocin infusion if the client's contraction frequency is every 3 minutes. Frequent contractions may lead to uterine hyperstimulation, which can reduce fetal blood flow and oxygenation, potentially causing fetal distress. Normal contraction frequency during labor is typically every 2 to 5 minutes.

Choice B rationale:

Contraction duration of 100 seconds is not an indication to discontinue the oxytocin infusion. The duration of contractions can vary during labor, and 100 seconds is within the normal range of contraction duration, which is usually 45 to 90 seconds.

Choice C rationale:

Fetal heart rate with moderate variability is not an indication to discontinue the oxytocin infusion. Moderate variability in fetal heart rate is a reassuring sign, indicating a healthy fetal response to labor. It shows that the fetus is tolerating the contractions well and is not experiencing fetal distress.

Choice D rationale:

A fetal heart rate of 118/min is not an indication to discontinue the oxytocin infusion. The normal fetal heart rate range is typically between 110 to 160 beats per minute, and a heart rate of 118/min falls within this normal range. However, if the fetal heart rate deviates significantly from the normal range or shows signs of distress, further assessment and intervention are required.

Choice A rationale:

Multiparity, or having given birth to multiple children, is associated with a decreased risk of ovarian cancer, not an increased risk. The protective effect may be due to the repeated ovulatory cycles that occur during pregnancy.

Choice B rationale:

Endometriosis is a condition where endometrial tissue grows outside the uterus. It is associated with an increased risk of ovarian cancer. The exact link is not fully understood, but it is believed that the inflammatory and hormonal changes in endometriosis may contribute to cancer development.

Choice C rationale:

Being under 40 years of age does not increase the risk of ovarian cancer. Advanced age is a known risk factor for ovarian cancer, with the highest incidence occurring in women over 60.

Choice D rationale:

Use of contraceptive medications, particularly oral contraceptives, has been shown to reduce the risk of ovarian cancer. These medications suppress ovulation and decrease the exposure of the ovaries to potential carcinogens.
