A nurse is evaluating the fetal heart rate tracing of a client who is in pre-term labor and receiving magnesium sulfate.
The nurse should identify that which of the following patterns indicates a potential adverse effect of the medication on the fetus?
Accelerations
Early decelerations
Variable decelerations
Absent variability
The Correct Answer is D
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.

Correct Answer is A
Explanation
Ultrasound.
An ultrasound can help determine the gestational age, fetal growth, placental location, and amniotic fluid volume of the fetus.
These factors can affect the risk of pre-term labor and delivery.
An ultrasound can also detect cervical changes that may indicate pre-term labor.
Choice B is wrong because a blood count is not specific for pre-term labor.
It may be done to check for anemia, infection, or other conditions that may affect the pregnancy, but it does not directly assess the risk of pre-term labor.
Choice C is wrong because a urine culture is not specific for pre-term labor.
It may be done to check for urinary tract infection, which can cause pre-term labor, but it does not directly assess the risk of pre-term labor.
Choice D is wrong because an amniocentesis is not usually done for pre-term labor.
It may be done to check for fetal lung maturity, chromosomal abnormalities, or infections, but it is an invasive procedure that carries some risks and complications.
It does not directly assess the risk of pre-term labor.
Correct Answer is D
Explanation
All of the above.
Respiratory distress syndrome (RDS) is a condition that affects preterm newborns who have immature lungs and lack sufficient surfactant.
Surfactant is a substance that helps keep the alveoli open and prevents them from collapsing.
Without enough surfactant, the newborn has difficulty breathing and may develop hypoxia and acidosis.
Choice A is wrong because tachypnea and grunting are signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as transient tachypnea of the newborn, pneumonia, or congenital heart defects.
Choice B is wrong because bradycardia and cyanosis are also signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as hypothermia, hypoglycemia, or sepsis.
Choice C is wrong because apnea and nasal flaring are also signs of respiratory distress, but they are not specific to RDS.
They can also be caused by other conditions such as intracranial ...
