A nurse is administering betamethasone to a client who is in pre-term labor at 28 weeks of gestation.
The nurse should explain that the purpose of this medication is to:
Reduce inflammation in the uterus
Enhance fetal lung maturity
Prevent infection in the amniotic fluid
Increase blood flow to the placenta
The Correct Answer is B
Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm delivery to enhance fetal lung maturity. Betamethasone stimulates the production of surfactant, a substance that lubricates the lungs and prevents them from collapsing when the baby breathes. This reduces the risk of respiratory distress syndrome and other complications in preterm infants.
Choice A is wrong because betamethasone does not reduce inflammation in the uterus.
Choice C is wrong because betamethasone does not prevent infection in the amniotic fluid.
Choice D is wrong because betamethasone does not increase blood flow to the placenta.
Normal ranges for gestational age are 37 to 42 weeks.
Preterm birth is defined as delivery before 37 weeks of gestation. Antenatal corticosteroids are recommended for women between 24 and 34 weeks of gestation who are at risk of preterm delivery within 7 days, and may be considered for women at 23 weeks of gestation or between 34 and 37 weeks of gestation depending on the clinical scenario.

Explanation
Leukocoria (white pupils) is a symptom of retinopathy of prematurity (ROP), an eye disease that can happen in premature babies.ROP happens when abnormal blood vessels grow on the retina, the light-sensitive layer of tissue in the back of the eye.
Choice B is wrong because strabismus (crossed eyes) is not a symptom of ROP, but a possible complication that can occur later in life.
Choice C is wrong because nystagmus (involuntary eye movements) is not a symptom of ROP, but another possible complication that can occur later in life.
Choice D is wrong because it includes choices B and C, which are incorrect.
Normal ranges for gestational age and birth weight are 38 to 42 weeks and 5.5 to 10 pounds, respectively.Babies born before 31 weeks or weighing less than 3 pounds are at risk for ROP.
Correct Answer is A
Explanation
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that helps close the ductus arteriosus, a blood vessel connecting two arteries of the heart (aorta and pulmonary artery) in fetus.This drug is effective only among premature babies.
Choice B.Prostaglandin E1 is wrong because it is used to keep the ductus arteriosus open in some congenital heart defects that require surgery.
Choice C.Furosemide is wrong because it is a diuretic that reduces fluid retention and blood pressure, but does not affect the ductus arteriosus.
Choice D.Digoxin is wrong because it is a cardiac glycoside that strengthens the heart muscle contractions and regulates the heart rhythm, but does not affect the ductus arteriosus.
