A nurse is reviewing the laboratory results of a client who is at 29 weeks of gestation and has pre-term labor.
Which of the following results indicates an infection that can trigger pre-term labor?
White blood cell count of 12,000/mm3
Hemoglobin level of 11 g/dL
Platelet count of 250,000/mm3
Blood glucose level of 90 mg/dL
The Correct Answer is A
A white blood cell count of 12,000/mm3 indicates an infection that can trigger pre-term labor. The normal range for white blood cell count in pregnancy is 5.7-15.0×10 9 /L, which is equivalent to 5,700-15,000/mm3.
A count above this range suggests an inflammatory response to an infection.
Choice B is wrong because a hemoglobin level of 11 g/dL is within the normal range for pregnancy, which is 10-14 g/dL.
Choice C is wrong because a platelet count of 250,000/mm3 is within the normal range for pregnancy, which is 150,000-400,000/mm3.
Choice D is wrong because a blood glucose level of 90 mg/dL is within the normal range for pregnancy, which is 70-110 mg/dL.

Correct Answer is B
Explanation
It will increase fetal lung maturity.
Betamethasone is a type of corticosteroid that is given to pregnant women who are at risk of preterm delivery between 24 and 34 weeks of gestation.It helps to improve neonatal outcomes by reducing the incidence of respiratory distress syndrome and other complications.Betamethasone works by stimulating the production and release of surfactant, a substance that lubricates the lungs and prevents them from collapsing when the baby breathes.
Choice A is wrong because betamethasone does not affect maternal blood pressure.
Choice C is wrong because betamethasone does not reduce uterine contractions.
Choice D is wrong because betamethasone does not prevent neonatal infection.
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%.
