A nurse is reviewing the medical record of a client who is at 34 weeks of gestation and has pre-term labor.
Which of the following findings is a risk factor for pre-term labor?
History of urinary tract infections
Maternal age of 25 years
Singleton pregnancy
Cervical length of 3 cm
The Correct Answer is A
History of urinary tract infections. According to the Mayo Clinic, untreated vaginal infections, such as urinary tract infections or sexually transmitted infections, are risk factors for preterm labor.
These infections can cause inflammation and irritation of the cervix, which can trigger contractions and cervical dilation.
Choice B is wrong because maternal age of 25 years is not a risk factor for preterm labor. In fact, women younger than 18 or older than 35 are more likely to have a preterm delivery.
Choice C is wrong because singleton pregnancy is not a risk factor for preterm labor. On the contrary, being pregnant with twins, triplets, or more (called "multiple gestations") is associated with a higher risk of preterm labor and birth.
Choice D is wrong because cervical length of 3 cm is not a risk factor for preterm labor. A short cervix (less than 2.5 cm) or a cervix that shortens in the second trimester instead of the third trimester is a risk factor for preterm delivery. A normal cervical length ranges from 3 to 5 cm during pregnancy.

Correct Answer is ["B","C","D","E"]
Explanation
Magnesium sulfate IV infusion can cause various adverse effects such asflushing,headache,nauseaanddrowsiness.
These are common and expected side effects of this medication.
Choice A is wrong because magnesium sulfate IV infusion does not causediarrhea.Diarrhea is a possible side effect of oral magnesium sulfate, which is used as a laxative.
However, oral magnesium sulfate is not used to treat pre-term labor or prevent seizures.
Normal ranges of magnesium in the blood are 1.7 to 2.2 mg/dL for adults.
Magnesium sulfate IV infusion is used to treat hypomagnesemia (low levels of magnesium in the blood) or to prevent seizures in pregnant women with pre-eclampsia, eclampsia or toxemia.
Correct Answer is D
Explanation
According to the search results, magnesium sulfate can have a negative effect on the fetal heart rate (FHR) by lowering the baseline, decreasing the variability, and reducing the reactivity or acceleration pattern.Absent variability means that there is no fluctuation in the FHR and it indicates fetal hypoxia or acidosis.
This is a potential adverse effect of magnesium sulfate on the fetus and requires immediate intervention.
Choice A.Accelerations is wrong because accelerations are transient increases in the FHR that indicate fetal well-being.They are not affected by magnesium sulfate.
Choice B.Early decelerations is wrong because early decelerations are decreases in the FHR that occur with uterine contractions and are caused by fetal head compression.They are benign and do not indicate fetal distress.They are not associated with magnesium sulfate.
Choice C.Variable decelerations is wrong because variable decelerations are abrupt decreases in the FHR that vary in shape, duration, and timing and are caused by umbilical cord compression.
They may or may not indicate fetal compromise.
