A nurse is caring for a pre-term newborn who has a patent ductus arteriosus (PDA).
Which of the following medications should the nurse expect to administer to close the ductus arteriosus?
Indomethacin
Prostaglandin E1
Furosemide
Digoxin
The Correct Answer is A
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.

Correct Answer is A
Explanation
Decreased frequency and intensity of contractions indicates that the client’s condition is improving.Preterm labor occurs when regular contractions result in the opening of your cervix before 37 weeks of pregnancy.
If preterm labor can’t be stopped, your baby will be born early and may have health problems.
Choice B is wrong because increased cervical dilation and effacement means that the cervix is thinning and opening more, which are signs of labor progression.
Choice C is wrong because increased amount and color of vaginal discharge may indicate infection, bleeding, or rupture of membranes, which are complications of preterm labor.
Choice D is wrong because decreased fetal heart rate variability means that the baby’s heart rate is not changing much, which may indicate fetal distress or hypoxia.A normal fetal heart rate variability is between 6 and 25 beats per minute.
Correct Answer is D
Explanation
According to the search results, magnesium sulfate can have a negative effect on the fetal heart rate (FHR) by lowering the baseline, decreasing the variability, and reducing the reactivity or acceleration pattern.Absent variability means that there is no fluctuation in the FHR and it indicates fetal hypoxia or acidosis.
This is a potential adverse effect of magnesium sulfate on the fetus and requires immediate intervention.
Choice A.Accelerations is wrong because accelerations are transient increases in the FHR that indicate fetal well-being.They are not affected by magnesium sulfate.
Choice B.Early decelerations is wrong because early decelerations are decreases in the FHR that occur with uterine contractions and are caused by fetal head compression.They are benign and do not indicate fetal distress.They are not associated with magnesium sulfate.
Choice C.Variable decelerations is wrong because variable decelerations are abrupt decreases in the FHR that vary in shape, duration, and timing and are caused by umbilical cord compression.
They may or may not indicate fetal compromise.
