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 C
Explanation
Choice A rationale:
Fentanyl is an opioid analgesic and is not used to counteract the effects of meperidine in the newborn. Both fentanyl and meperidine are opioids, and using fentanyl in this context would not counteract the effects of meperidine.
Choice B rationale:
Flumazenil is a medication used to reverse the effects of benzodiazepines, not opioids like meperidine. It is not appropriate for countering the effects of meperidine in the newborn.
Choice C rationale:
Naloxone is an opioid antagonist that can reverse the effects of opioids like meperidine. When a newborn has been exposed to opioids during labor, such as meperidine given to the mother, there is a risk of respiratory depression in the newborn. Naloxone can quickly reverse this effect and restore normal respiratory function.
Choice D rationale:
Benztropine is an anticholinergic medication used to treat side effects of antipsychotic drugs and is not relevant in this situation. It would not counteract the effects of meperidine on the newborn.
Correct Answer is B
Explanation
Choice A rationale:
An axillary temperature of 36.5°C (97.7°F) is within the normal range for a newborn. Normal axillary temperature for a newborn is typically between 36.5°C to 37.5°C (97.7°F to 99.5°F).
Choice B rationale:
This is the correct choice. Nasal flaring in a newborn is a concerning sign and may indicate respiratory distress. It suggests that the baby is having difficulty breathing and should be reported to the provider for further evaluation.
Choice C rationale:
A heart rate of 158/min is within the normal range for a newborn. The normal heart rate for a newborn can range from 100 to 160 beats per minute.
Choice D rationale:
Having one void since birth is not a concerning finding for a 10-hour-old newborn. In the early hours of life, the frequency of voids may vary, but the baby should have an increasing number of wet diapers in the following days.
