After teaching a pregnant woman about the hormones produced by the placenta, the nurse determines that the teaching was successful when the woman identifies which hormone produced as being the basis for pregnancy tests?
Human placental lactogen (hPL).
Estrogen (estriol).
Progesterone (progestin).
Human chorionic gonadotropin (hCG).
The Correct Answer is D
A. Human placental lactogen (hPL) is a hormone produced by the placenta that helps regulate the metabolism of the mother and fetus, but it is not used as the basis for pregnancy tests. It plays a role in modulating the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus.
B. Estrogen (estriol) is another hormone produced by the placenta, which is important for maintaining pregnancy and preparing the body for childbirth. However, it is not the hormone detected by pregnancy tests. Estriol levels increase significantly during pregnancy but are not used as a marker for pregnancy tests.
C. Progesterone (progestin) is crucial for maintaining the uterine lining and supporting early pregnancy. While it is essential for a successful pregnancy, it is not the hormone that pregnancy tests detect. Progesterone helps prevent uterine contractions and supports the endometrium.
D. Human chorionic gonadotropin (hCG) is the hormone detected by pregnancy tests. It is produced by the placenta shortly after the embryo attaches to the uterine lining. The presence of hCG in the blood or urine is a reliable indicator of pregnancy, which is why it is the basis for pregnancy tests.

Correct Answer is D
Explanation
Choice A reason:
Measuring urinary output. This is not the priority nursing care associated with an oxytocin infusion, because urinary output is not directly affected by oxytocin. Urinary output may be affected by other factors, such as fluid intake, dehydration, or kidney function, but these are not related to oxytocin administration. • Choice B reason:
Evaluating cervical dilation. This is also not the priority nursing care associated with an oxytocin infusion, because cervical dilation is a result of uterine contractions, not oxytocin itself. Oxytocin is used to stimulate or augment uterine contractions, but it does not cause cervical dilation directly. Cervical dilation is important to monitor during labor, but it is not the main focus of oxytocin infusion. • Choice C reason:
Increasing infusion rate every 30 minutes. This is not the priority nursing care associated with an oxytocin infusion, because increasing the infusion rate every 30 minutes is not a standard protocol for oxytocin administration. The infusion rate should be adjusted according to the patient's response and the provider's orders, but not arbitrarily or routinely. Increasing the infusion rate too quickly or too often can cause hyperstimulation of the uterus, which can be dangerous for both the mother and the fetus.
• Choice D reason:
Monitoring uterine response. This is the correct answer and the priority nursing care associated with an oxytocin infusion, because oxytocin can cause excessive or prolonged uterine contractions, which can lead to fetal distress, uterine rupture, or placental abruption. Therefore, the nurse must monitor the frequency, duration, and intensity of uterine contractions, as well as the fetal heart rate and blood pressure, to ensure that oxytocin is having the desired effect and not causing any adverse outcomes.
Correct Answer is C
Explanation
Choice A reason:
Acrocyanosis (choice A) is a common and relatively normal finding in newborns, especially in the first few days of life. It refers to the bluish discoloration of the hands and feet due to peripheral vasoconstriction. Acrocyanosis alone does not necessarily indicate significant difficulty with oxygenation and is usually a transient and benign condition.
Choice B reason:
A respiratory rate of 54 breaths/minute (choice B) is within the normal range for a newborn. The normal respiratory rate for a newborn can range from 30 to 60 breaths per minute. While an abnormal respiratory rate outside this range may be a concern, a rate of 54 breaths/minute is not indicative of significant oxygenation difficulty by itself.
Choice C reason:
Nasal flaring in a newborn is a concerning sign that suggests the baby is experiencing difficulty with oxygenation. When a newborn is having trouble getting enough oxygen, they may instinctively open their nostrils wider (nasal flaring) to increase the airflow into the nose and improve oxygen intake. This is a compensatory mechanism to overcome respiratory distress and is often seen in newborns with respiratory problems. Nasal flaring is an important clinical sign that indicates the baby may be struggling to breathe adequately and requires further evaluation and intervention by the healthcare team.
Choice D reason:
Abdominal breathing (choice D) is a normal breathing pattern in newborns. Newborns predominantly use their diaphragm to breathe, which results in abdominal movements during respiration. This is a normal and expected finding in healthy newborns and does not necessarily suggest oxygenation problems.
