The client is receiving magnesium sulfate IV infusion.
Which of the following are expected adverse effects of this medication? (Select all that apply)
Diarrhea
Flushing
Headache
Nausea
Drowsiness
Correct Answer : B,C,D,E
Magnesium sulfate IV infusion can cause various adverse effects such as flushing, headache, nausea and drowsiness.
These are common and expected side effects of this medication.
Choice A is wrong because magnesium sulfate IV infusion does not cause diarrhea. Diarrhea is a possible side effect of oral magnesium sulfate, which is used as a laxative.
However, oral magnesium sulfate is not used to treat pre-term labor or prevent seizures.
Normal ranges of magnesium in the blood are 1.7 to 2.2 mg/dL for adults.
Magnesium sulfate IV infusion is used to treat hypomagnesemia (low levels of magnesium in the blood) or to prevent seizures in pregnant women with pre-eclampsia, eclampsia or toxemia.

Correct Answer is A
Explanation
Amniotic fluid index of 4 cm indicates oligohydramnios, which means too little amniotic fluid.This can cause fetal growth restriction, cord compression, and congenital anomalies.
Choice B is wrong because amniotic fluid index of 8 cm is within the normal range of 5 to 25 cm.
Choice C is wrong because amniotic fluid index of 12 cm is also within the normal range and close to the median value of 14 cm.
Choice D is wrong because amniotic fluid index of 16 cm is also within the normal range and does not indicate oligohydramnios.
Correct Answer is B
Explanation
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.
