While talking with a pregnant woman who has undergone genetic testing, the woman informs the nurse that her baby will be born with Down syndrome. The nurse understands that Down syndrome is an example of:

Choice A Reason: This is incorrect because difficulty in arousing is a sign of magnesium toxicity, which is a serious complication of magnesium sulfate therapy. Magnesium toxicity can cause central nervous system depression, muscle weakness, and cardiac arrest. The nurse should monitor the client's level of consciousness and stop the infusion if the client becomes lethargic or unresponsive.

Choice B Reason: This is correct because deep tendon reflexes 2+ indicate a normal and expected response to magnesium sulfate therapy. Magnesium sulfate is a muscle relaxant that can reduce the risk of seizures in gestational hypertension. The nurse should assess the client's deep tendon reflexes regularly and maintain them at 2+ or slightly diminished.

Choice C Reason: This is incorrect because urinary output of 30 mL per hour is below the normal range of 40 to 80 mL per hour and may indicate renal impairment or dehydration. Magnesium sulfate can cause renal toxicity or fluid retention, which can affect the urinary output. The nurse should monitor the client's urinary output and fluid balance and report any abnormalities to the doctor.

Choice D Reason: This is incorrect because respiratory rate of 10 breaths/minute is below the normal range of 12 to 20 breaths/minute and may indicate respiratory depression. Magnesium sulfate can cause respiratory depression or failure, which can be life-threatening. The nurse should monitor the client's respiratory rate and oxygen saturation and administer oxygen or antidote if needed.

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.
