A nurse is preparing to administer betamethasone (Celestone) to a client who is at 31 weeks of gestation and has pre-term labor.
What is the purpose of this medication?
To suppress uterine contractions
To prevent infection
To promote fetal lung maturity
To reduce maternal blood pressure
The Correct Answer is C
To promote fetal lung maturity. Betamethasone (Celestone) is a type of corticosteroid that can help reduce the risk of respiratory distress syndrome and other complications in preterm infants by accelerating the development of their lungs. It is recommended for pregnant women between 24 0/7 weeks and 36 6/7 weeks of gestation who are at risk of preterm delivery within 7 days.
Choice A is wrong because betamethasone does not suppress uterine contractions.
It has no effect on the cause of preterm labor.
Choice B is wrong because betamethasone does not prevent infection.
It may actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because betamethasone does not reduce maternal blood pressure.
It may actually cause hypertension and hyperglycemia as side effects.

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 A
Explanation
Thromboembolism.
Prolonged bed rest increases the risk of venous stasis and blood clot formation in the lower extremities, which can lead to pulmonary embolism if the clot dislodges and travels to the lungs.
This is a life-threatening complication that requires immediate treatment.
Choice B. Placental abruption is wrong because it is not caused by bed rest, but by trauma, hypertension, cocaine use, or other factors that can cause the placenta to separate from the uterine wall.
Choice C. Uterine atony is wrong because it is not caused by bed rest, but by overdistension of the uterus, prolonged labor, infection, or other factors that can impair the contraction of the uterine muscles after delivery.
Choice D. Infection is wrong because it is not caused by bed rest, but by poor hygiene, invasive procedures, or other factors that can introduce microorganisms into the reproductive tract.
Normal ranges for maternal heart rate are 60-100 beats per minute and blood pressure are 110-140/60-90 mm Hg.
Normal range for fetal heart rate is 110-160 beats per minute.
