Final answer:
The fetal complications caused by Indomethacin use are oligohydramnios and premature closure of ductus arteriosus. Oligohydramnios can cause limb contractures and hypoplastic lungs, while the premature closure of the ductus arteriosus can lead to cardiac and respiratory issues.
Step-by-step explanation:
The correct answer to the question of which fetal complications can result from Indomethacin use is: a) Oligohydramnios and premature closure of ductus arteriosus. Indomethacin is a type of nonsteroidal anti-inflammatory drug (NSAID) that can cause various fetal complications when used during pregnancy. One of these potential complications is oligohydramnios, which is a condition characterized by too little amniotic fluid surrounding the fetus. This can lead to issues such as limb contractures and, importantly, hypoplastic lungs, which are underdeveloped and can be life-threatening if the baby is born with this condition. In addition, Indomethacin can lead to the premature closure of the ductus arteriosus, a vital blood vessel in the fetal heart that normally closes after birth. If it closes prematurely, it can cause serious cardiac and respiratory issues due to the disruption in the normal circulation pattern of a fetus.
