A nurse is caring for a client who is in labor and has an external fetal monitor. The nurse observes late decelerations on the monitor strip and interprets them as indicating which of the following?
Umbilical cord compression
Uteroplacental insufficiency
Fetal head compression
Material bradycardia
The Correct Answer is B
The correct answer is B. Uteroplacental insufficiency.
A. Umbilical cord compression is more commonly associated with variable decelerations, not late decelerations. Variable decelerations are characterized by abrupt decreases and increases in the fetal heart rate.
B. Late decelerations are indicative of uteroplacental insufficiency.
Uteroplacental insufficiency refers to a decrease in blood flow and oxygen supply from the mother to the fetus. Late decelerations occur after the peak of the contraction and may suggest inadequate oxygenation to the fetus.
C. Fetal head compression is associated with early decelerations, not late decelerations. Early decelerations typically coincide with the contractions and are considered a normal response to head compression during contractions.
D. Maternal bradycardia is not typically associated with late decelerations. Late decelerations are primarily related to issues with oxygenation and blood flow to the fetus.

Correct Answer is A
Explanation
The correct answer is A.
A. Determine respiratory function: The priority is to assess the client's airway, breathing, and circulation (ABCs). If the client becomes unresponsive, the nurse should quickly assess whether the airway is clear, check for breathing, and determine if there is a pulse. This initial assessment is crucial for identifying and addressing any immediate life-threatening issues.
B. Increase the TV fluid rate: While fluid administration may be necessary in certain situations, it is not the first priority when a client becomes unresponsive. Assessing respiratory function and circulation takes precedence to address immediate life-threatening concerns.
C. Access emergency medications from the cart: Accessing emergency medications may be necessary, but it should occur after the initial assessment of the client's airway, breathing, and circulation. Administering medications without first assessing the client's ABCs may delay appropriate interventions.
D. Collect a maternal blood sample for coagulopathy studies: This action is important for assessing coagulation status, but it is not the first priority when a client becomes unresponsive. The immediate focus should be on ensuring the client has a patent airway, is breathing, and has a pulse.
Correct Answer is B
Explanation
A. "This medication will stop your labor": Betamethasone is not intended to stop labor. It is given to promote fetal lung maturity and reduce the risk of complications associated with preterm birth.
B. "This medication stimulates fetal lung maturity": This is the correct statement. Betamethasone is administered to enhance the production of surfactant in the fetal lungs, improving respiratory outcomes for the preterm infant.
C. "This medication will decrease your risk for uterine infections": Betamethasone does not directly decrease the risk of uterine infections. Its primary benefit is in promoting fetal lung maturity.
D. "This medication will increase your baby's weight": Betamethasone is not given to increase the baby's weight. Its main focus is on improving lung function and reducing respiratory complications in preterm infants.
