Zorluk: ZorAnte/Intra/Postpartum and Newborn Care

The interdisciplinary team is managing a client's induced labor. Analysis of the continuous electronic fetal tracing reveals a baseline heart rate of 155 bpm with minimal variability. The nurse notes a pattern of gradual, symmetrical decreases in the fetal heart rate where the onset, nadir, and recovery of each deceleration occur after the beginning, peak, and end of the respective uterine contractions. Given these findings, which of the following immediate actions must the nurse implement? Select all that apply.

  1. Terminate the oxytocin infusion immediately.Cevap
  2. B
    Prepare the equipment necessary to initiate a transcervical amnioinfusion.
  3. Reposition the client into a lateral decubitus position.Cevap
  4. D
    Delegate the continuous measurement of maternal vital signs to an unlicensed assistive personnel.
  5. Administer an intravenous bolus of lactated Ringer's solution.Cevap
  6. F
    Perform fetal scalp stimulation during the deceleration to assess for a reactive acceleration.

Cevap

The nurse must terminate the oxytocin infusion immediately, reposition the client into a lateral decubitus position, and administer an intravenous bolus of lactated Ringer's solution.
The clinical presentation describes late decelerations, which signify uteroplacental insufficiency and fetal hypoxemia. Appropriate intrauterine resuscitation includes maximizing placental blood flow and maternal oxygenation. Terminating the oxytocin stops uterine contractions that are compressing placental vessels. Repositioning the client laterally relieves compression of the inferior vena cava, increasing cardiac output. Administering an intravenous fluid bolus expands intravascular volume, further improving perfusion to the placenta.

Adım Adım Çözüm

1
Analyze the fetal heart rate tracing to identify the specific pattern.
The pattern shows a gradual decrease with the nadir occurring after the contraction peak, which defines a late deceleration.
Accurate pattern recognition is necessary to determine the underlying pathophysiology and appropriate interventions.
2
Correlate the identified pattern with its physiological cause.
Late decelerations are caused by uteroplacental insufficiency, indicating the fetus is experiencing hypoxemia during contractions. The minimal variability further suggests potential acidemia.
Understanding that the placenta is not delivering adequate oxygen guides the nurse toward resuscitation measures.
3
Prioritize interventions that maximize maternal oxygenation and placental blood flow.
The nurse determines that immediate intrauterine resuscitation is required, prioritizing actions over further assessments.
Delaying treatment or misinterpreting the severity can lead to severe fetal compromise or hypoxic-ischemic injury.
4
Select the appropriate intrauterine resuscitation actions.
The correct actions are stopping oxytocin (to stop contractions), repositioning laterally (to relieve caval compression), and giving an IV fluid bolus (to expand volume).
These targeted actions directly reverse the mechanical and physiological factors contributing to uteroplacental insufficiency.
