Fetal heart rate decelerations indicate a possible compromise of fetal oxygenation and should be reported to the provider immediately. Decelerations can be caused by various factors such as cord compression, uterine hyperstimulation, maternal hypotension, or placental abruption .
Choice A is wrong because a fetal heart rate of 140 beats per minute is within the normal range of 110 to 160 beats per minute .

Correct Answer is C
Explanation
To accelerate fetal lung maturity.Corticosteroids are given to pregnant women with severe pre-eclampsia who are at risk of preterm delivery to help the development of the fetus’s lungs and reduce the risk of respiratory distress syndrome.
This can improve the survival and health outcomes of the newborn.
Choice A is wrong because corticosteroids do not reduce inflammation in pre-eclampsia.They are used for other inflammatory conditions such as asthma or arthritis.
Choice B is wrong because corticosteroids do not prevent infection in pre-eclampsia.They can actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because corticosteroids do not increase platelet count in pre-eclampsia.They can actually decrease the platelet count by causing thrombocytopenia.
Correct Answer is C
Explanation
C. Fetal heart rate decelerations.
Fetal heart rate decelerations are temporary drops in the fetal heart rate that can indicate fetal distress or lack of oxygen.There are three types of decelerations: early, late and variable.Early decelerations are benign and caused by compression of the fetus’s head during a uterine contraction.Late decelerations are caused by uteroplacental insufficiency, which is a decrease in blood flow to the placenta.Variable decelerations are the most common type and vary in shape, duration and intensity.They are often caused by cord compression or other factors that affect fetal oxygenation.
•
A. Fetal heart rate of 140 beats per minute.
Statement is wrong because this is a normal fetal heart rate.The normal range for fetal heart rate is 120-160 beats per minute.
•
B. Uterine contractions every 10 minutes.
Statement is wrong because this is a normal frequency for uterine contractions during early labor.
The normal range for uterine contractions is 5-10 minutes apart.
•
D. Uterine contractions lasting 60 seconds.
Statement is wrong because this is a normal duration for uterine contractions during active labor.
The normal range for uterine contractions is 45-90 seconds long.
