A nurse is caring for a client in labor who has an internal fetal scalp electrode applied for continuous fetal heart rate (FHR) monitoring.
The nurse notes a pattern of late decelerations on the FHR tracing.
What is the priority nursing intervention?
Change the client's position.
Administer oxygen via face mask
Increase intravenous fluid rate.
Notify the health care provider.
The Correct Answer is D
Notify the health care provider. Late decelerations are a sign of uteroplacental insufficiency, which means that the blood flow and oxygen supply to the placenta and the fetus are compromised. This is a serious condition that can lead to fetal hypoxia and acidosis. The priority nursing intervention is to inform the health care provider who can assess the situation and decide on the appropriate course of action, such as delivery by cesarean section.
Choice A is wrong because changing the client’s position may not improve the blood flow to the placenta if there is a problem with the placenta itself, such as placental abruption.
Choice B is wrong because administering oxygen via face mask may not be enough to correct the fetal hypoxia caused by uteroplacental insufficiency.
Choice C is wrong because increasing intravenous fluid rate may not improve the blood flow to the placenta if there is a problem with the maternal blood pressure, such as hypotension from epidural analgesia.

Correct Answer is B
Explanation
Lecithin/sphingomyelin (L/S) ratio.
This is a test that measures the amount of two phospholipids in the amniotic fluid that are important for the production of surfactant, a substance that helps the lungs expand and prevents them from collapsing.A higher L/S ratio indicates more surfactant and greater fetal lung maturity.The normal range for L/S ratio is 2:1 or higher at term.
Choice A is wrong because alpha-fetoprotein (AFP) is a protein produced by the fetus that can be measured in the amniotic fluid or maternal blood.It is used to screen for neural tube defects and other abnormalities, not for fetal lung maturity.
Choice C is wrong because Kleihauer-Betke test is a blood test that detects fetal red blood cells in the maternal circulation.It is used to diagnose fetomaternal hemorrhage, a condition where fetal blood leaks into the mother’s blood, not for fetal lung maturity.
Choice D is wrong because indirect Coombs’ test is a blood test that detects antibodies in the mother’s blood that may attack the fetal red blood cells.It is used to screen for Rh incompatibility or other blood group sensitization, not for fetal lung maturity.
Correct Answer is ["A","B","C","D"]
Explanation
The correct answer is choice A, B, C and D.These are the four components of a biophysical profile (BPP) that are scored as 2 (normal) or 0 (abnormal) based on ultrasound examination.The fifth component is the nonstress test (NST) that measures the fetal heart rate reactivity.A total score of 8 or 10 is normal, 6 is equivocal, and 4 or less is abnormal.
Choice E is wrong because fetal position is not a part of the BPP score.Fetal position is determined by ultrasound but it does not affect the score.
Normal ranges for each component are:
• Fetal breathing movement: One or more episodes of fetal breathing lasting at least 30 seconds within 30 minutes.
• Fetal tone: One or more episodes of active extension and flexion of a fetal extremity or opening and closing of the hand within 30 minutes.
• Reactive fetal heart rate: Two or more fetal heart rate accelerations that peak at least 15 beats per minute above the baseline and last at least 15 seconds from baseline to baseline during 20 minutes of observation.
• Amniotic fluid volume: A single deepest vertical pocket of amniotic fluid that measures at least 2 centimeters.
• Gross body movement: Three or more discrete body or limb movements within 30 minutes.
