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 B
Explanation
Choice A rationale:
Restricting protein intake to less than 40 g/day is not appropriate for a client with preeclampsia with severe features. While protein restriction might be advised in some cases of preeclampsia, it is not a priority in severe cases where the focus is on managing potential complications.
Choice B rationale:
Initiating seizure precautions is essential in managing a client with preeclampsia with severe features. Preeclampsia can lead to eclampsia, a condition characterized by seizures. Seizure precautions involve implementing measures to prevent injury during a seizure, such as padding the side rails of the bed, ensuring a clear environment, and having emergency equipment readily available.
Choice C rationale:
Initiating an infusion of 0.9% sodium chloride at 150 ml/hr is not directly related to managing preeclampsia with severe features. Although intravenous fluids may be necessary in some cases, the priority in this situation is to prevent and manage potential seizures.
Choice D rationale:
Encouraging the client to ambulate twice per day is not appropriate for a client with preeclampsia with severe features. Bed rest is often recommended in severe cases to reduce stress on the cardiovascular system and decrease the risk of complications.
Correct Answer is A
Explanation
The correct answer is: A. Hemoglobin 12 g/dL.
Choice A reason:
Hemoglobin levels in newborns are expected to be significantly higher than in adults due to the physiological adaptation to life outside the womb. The normal range for a newborn’s hemoglobin is approximately 14 to 24 g/dL1234. A level of 12 g/dL is below the expected range and could indicate anemia or other underlying conditions that may require further investigation and intervention by the healthcare provider.
Choice B reason:
The glucose level in a newborn can vary, especially within the first few hours after birth. Normal blood glucose levels for a newborn 1 to 2 hours old can be as low as 25 mg/dL and can rise to adult levels (60-100 mg/dL) within the first few days5. A glucose level of 50 mg/dL in a 24-hour-old newborn falls within the acceptable range and would not typically require reporting to the provider unless accompanied by symptoms of hypoglycemia.
Choice C reason:
Bilirubin levels in newborns can be elevated due to the normal breakdown of fetal hemoglobin as the baby’s liver matures. Normal bilirubin levels for a newborn can range from 1.0 to 12.0 mg/dL6. A bilirubin level of 4 mg/dL is within the normal range for a 24-hour-old newborn and is not typically a cause for concern unless there are signs of jaundice or other symptoms.
Choice D reason:
The normal platelet count for a newborn ranges from 150,000 to 450,000/mm³7. A platelet count of 200,000/mm³ is well within the normal range for a newborn and would not need to be reported to the healthcare provider.
