A nurse is caring for a client who is in active labor. The nurse notes early decelerations of the FHR on the fetal monitor tracing. The nurse should identify that which of the following conditions causes early decelerations in the FHR?
Fetal hypoxemia.
Cord compression.
Uteroplacental insufficiency.
Head compression.
The Correct Answer is D
Choice A rationale:
Fetal hypoxemia is associated with late decelerations in the fetal heart rate (FHR) tracing. It occurs when the fetus experiences a decreased supply of oxygen, typically due to placental insufficiency or maternal hypotension.
Choice B rationale:
Cord compression can lead to variable decelerations in the FHR tracing. It occurs when the umbilical cord is compressed, restricting blood flow to the fetus temporarily.
Choice C rationale:
Uteroplacental insufficiency causes late decelerations in the FHR tracing. It refers to an inadequate blood flow between the uterus and placenta, resulting in reduced oxygen supply to the fetus.
Choice D rationale:
Head compression is the correct answer for early decelerations in the FHR tracing. It happens during contractions when the fetal head is compressed by the maternal pelvis, leading to a temporary vagal response that slows the heart rate.

Correct Answer is A
Explanation
Choice A rationale:
When late decelerations are noted in the fetal heart rate (FHR) tracing, it indicates that the fetal oxygen supply may be compromised. The nurse should first change the client's position, such as moving her to the left lateral position or a hands-and-knees position, to improve uteroplacental blood flow and relieve pressure on the vena cava.
Choice B rationale:
Palpating the uterus to assess for tachysystole is not the priority action when late decelerations are observed. Tachysystole refers to excessively frequent uterine contractions and may contribute to fetal distress, but the immediate concern is addressing the decelerations.
Choice C rationale:
Increasing the client's IV infusion rate may not address the underlying cause of late decelerations. While maintaining hydration is important, it's not the first action to take in this situation.
Choice D rationale:
Administering oxygen at 10 L/min via a non-rebreather mask may be beneficial for the client and fetus, but it is not the first action to take. The nurse should address the position change first to improve oxygenation through better blood flow before considering supplemental oxygen.
Correct Answer is A
Explanation
A. Palpating the client's uterine fundus is the priority intervention because excessive postpartum bleeding could indicate uterine atony, where the uterus fails to contract effectively. Assessing the fundus will help determine if it is boggy and if fundal massage is needed to promote uterine contraction and reduce bleeding.
B. Assisting the client to urinate is an important intervention if the bladder is distended, as a full bladder can prevent the uterus from contracting properly. However, palpating the fundus to assess the source of bleeding takes priority over assisting with urination.
C. Preparing to administer oxytocic medication may be necessary if the uterine fundus is boggy and does not respond to massage, but the first step is to assess the fundus and attempt manual intervention before proceeding with medication.
D. Increasing the client's fluid intake can help maintain circulation and prevent dehydration, but it does not address the immediate concern of postpartum hemorrhage. Palpating the fundus is the priority action in this scenario
