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

Answer and Explanation

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 C

Explanation

True labor contractions cause cervical dilation and effacement.

This means that the cervix opens up and thins out to prepare for the baby’s passage through the birth canal.

Cervical changes can be measured by a pelvic exam.

Choice A is wrong because true labor contractions are regular and do not subside with rest.False labor contractions are irregular and may stop when you change position or activity level.

Choice B is wrong because false labor contractions are usually felt in the front of the abdomen, not in the lower back.True labor contractions may start in the back and radiate to the abdomen.

Choice D is wrong because false labor contractions do not increase in intensity with ambulation.True labor contractions may become stronger and closer together when you walk.

Normal ranges for cervical dilation and effacement vary depending on the stage of labor, but generally, full dilation is 10 cm and full effacement is 100%.

A. Hematocrit 45% B. Platelets 150,000/mm3 C. White blood cell count 25,000/mm3 D. Blood glucose 80 mg/dL

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.
