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

Answer and Explanation

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 A

Explanation

Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm labor to improve neonatal outcomes.Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing after birth.This reduces the risk of respiratory distress syndrome, a common complication of preterm birth.

Choice B is wrong because betamethasone does not decrease the risk of infection in the newborn.In fact, it may increase the risk of maternal and neonatal infections by suppressing the immune system.

Choice C is wrong because betamethasone does not increase blood glucose levels in the newborn.However, it may cause transient hyperglycemia in the mother, which should be monitored and treated if necessary.

Choice D is wrong because betamethasone does not decrease the risk of bleeding in the newborn.It may increase the risk of intraventricular hemorrhage, a type of bleeding in the brain, if given before 24 weeks of gestation.Therefore, it should be used with caution in this population and only after a family’s decision regarding resuscitation.

A. Administer magnesium sulfate intravenously B. Prepare for an emergency cesarean section C. Place the client in Trendelenburg position D. Administer antibiotics prophylactically

Correct Answer is B

Explanation

Prepare for an emergency cesarean section.This is because the client has pre-term labor that has not responded to tocolytic therapy, which are drugs that are used to delay delivery for a short time.The client’s cervix is dilated to 4 cm and she is experiencing regular contractions every 3 minutes, which are signs of active labor.The baby is at 33 weeks of gestation, which is premature and may have complications such as respiratory distress syndrome or bleeding in the brain.

Therefore, the client needs an emergency cesarean section to deliver the baby as soon as possible and prevent further risks.

Choice A is wrong because administering magnesium sulfate intravenously is a type of tocolytic therapy that the client has already failed.Magnesium sulfate may also have side effects such as nausea, vomiting, flushing, headache, and muscle weakness.

Choice C is wrong because placing the client in Trendelenburg position, which is lying on the back with the feet elevated above the head, is not recommended for preterm labor.This position may increase the risk of aspiration, decrease cardiac output, and impair gas exchange.

Choice D is wrong because administering antibiotics prophylactically is not indicated for preterm labor unless there is evidence of infection in the uterus or membranes.

Antibiotics may also cause allergic reactions or bacterial resistance
