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 A
Explanation
Decreased frequency and intensity of contractions indicates that the client’s condition is improving.Preterm labor occurs when regular contractions result in the opening of your cervix before 37 weeks of pregnancy.
If preterm labor can’t be stopped, your baby will be born early and may have health problems.
Choice B is wrong because increased cervical dilation and effacement means that the cervix is thinning and opening more, which are signs of labor progression.
Choice C is wrong because increased amount and color of vaginal discharge may indicate infection, bleeding, or rupture of membranes, which are complications of preterm labor.
Choice D is wrong because decreased fetal heart rate variability means that the baby’s heart rate is not changing much, which may indicate fetal distress or hypoxia.A normal fetal heart rate variability is between 6 and 25 beats per minute.
Correct Answer is C
Explanation
White blood cell count 25,000/mm3.
This indicates a potential complication of necrotizing enterocolitis (NEC), which is the death of intestinal tissue in premature or sick newborns.A high white blood cell count can be a sign of infection or inflammation in the bowel, which are common features of NEC.
Choice A is wrong because hematocrit 45% is within the normal range for newborns.
Hematocrit measures the percentage of red blood cells in the blood.
A low hematocrit can indicate blood loss or anemia, which can be complications of NEC, but a normal hematocrit does not rule out NEC.
Choice B is wrong because platelets 150,000/mm3 is also within the normal range for newborns.
Platelets are cells that help the blood clot.A low platelet count can indicate a consumption coagulopathy, which is a bleeding disorder that can occur in severe cases of NEC.
However, a normal platelet count does not exclude NEC.
Choice D is wrong because blood glucose 80 mg/dL is also within the normal range for newborns.
Blood glucose measures the amount of sugar in the blood.
A low blood glucose can indicate hypoglycemia, which can be caused by sepsis or other conditions that mimic NEC, but a normal blood glucose does not eliminate NEC.
