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 D
Explanation
Choice A rationale:
The client's statement about needing to have the IUD replaced each year is incorrect. The lifespan of most IUDs is longer than a year. Copper IUDs can last up to 10 years, and hormonal IUDs can last between 3 to 7 years, depending on the brand.
Choice B rationale:
The client's statement about needing to apply a spermicide prior to intercourse is unrelated to the correct use of an intrauterine device (IUD) for contraception. Spermicides are not required when using an IUD.
Choice C rationale:
The client's statement about expecting periods to stop while having the IUD is incorrect. Hormonal IUDs can often lead to lighter periods, and in some cases, periods may stop altogether. However, with a copper IUD, periods usually remain the same.
Choice D rationale:
This is the correct choice. The client's statement indicates an understanding of the teaching. Checking for the string each month after menstruation is crucial because it confirms that the IUD is still in place, reducing the risk of unintended pregnancy.
Correct Answer is A
Explanation
Choice A rationale:
Terbutaline is a medication commonly used to stop preterm labor by relaxing the uterine muscles. However, it is contraindicated in clients with heart disease or certain cardiac conditions, as it can cause cardiovascular side effects such as increased heart rate, palpitations, and potential arrhythmias.
Choice B rationale:
Cervical dilation of 2 cm is a typical sign of preterm labor, and the prescription for terbutaline is appropriate to prevent further cervical dilation and delay delivery.
Choice C rationale:
A gestational age of 34 weeks indicates preterm labor, which is precisely the scenario where terbutaline would be administered to halt labor progression and extend the pregnancy.
Choice D rationale:
Allergy to penicillin is unrelated to the administration of terbutaline, as they are different medications with distinct mechanisms of action and side effects.
