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:
Before an amniocentesis, it is essential for the client to empty their bladder. A full bladder can interfere with the procedure, as it may obstruct the needle's entry into the uterus and increase the risk of accidental bladder puncture.
Choice B rationale:
Nothing by mouth (NPO) for 4 hours is not necessary for an amniocentesis. It is a relatively simple and quick procedure that does not require fasting.
Choice C rationale:
Ingesting 3 liters of water is not indicated before an amniocentesis. While some ultrasound examinations may require a full bladder, this is not the case for an amniocentesis.
Choice D rationale:
Nipple stimulation is not relevant or necessary before an amniocentesis. Nipple stimulation can trigger uterine contractions, which might be undesirable before the procedure, especially if the client is not in labor.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should plan to administer Ampicillin to the client with a group B streptococcus (GBS) B-hemolytic infection. Ampicillin is the first-line antibiotic treatment for intrapartum prophylaxis in GBS-positive pregnant women. It helps prevent the transmission of the bacteria from the mother to the newborn, reducing the risk of early-onset GBS infection in the infant.
Choice B rationale:
Azithromycin is not the appropriate choice for treating GBS B-hemolytic infection during labor. While Azithromycin is effective against certain bacteria, it is not the recommended antibiotic for GBS prophylaxis in labor. Ampicillin or Penicillin is the preferred medication in this scenario.
Choice C rationale:
Ceftriaxone is not the appropriate medication for treating GBS B-hemolytic infection during labor. Ceftriaxone belongs to the cephalosporin class of antibiotics and is not the first-line treatment for GBS prophylaxis. Ampicillin or Penicillin is the preferred choice.
Choice D rationale:
Acyclovir is an antiviral medication and is not indicated for the treatment of GBS B-hemolytic infection. GBS is a bacterial infection, and antiviral medications like Acyclovir do not have an effect on bacteria.
