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 B
Explanation
Choice A reason:
Inspecting if the urethral opening appears circular. This is a correct action for the nurse to do, as it helps to identify any abnormalities in the urethral opening, such as hypospadias or epispadias, which are congenital defects where the opening is located on the underside or the top of the penis, respectively. • Choice B reason:
Retracting the foreskin over the glans to assess for secretions. This is an incorrect action for the nurse to avoid, as it can cause pain, bleeding, and infection in the newborn. The foreskin is usually adhered to the glans in newborns and should not be forcibly retracted. It will gradually loosen over time and can be retracted by the child himself when he is older. •
Choice C reason:
Palpating if testes are descended into the scrotal sac. This is a correct action for the nurse to do, as it helps to detect any undescended testes, which are more common in preterm infants and can increase the risk of infertility and testicular cancer later in life. • Choice D reason:
Inspecting the genital area for irritated skin. This is a correct action for the nurse to do, as it helps to identify any signs of diaper rash, fungal infection, or allergic reaction in the newborn's skin.
Correct Answer is A
Explanation
Choice A reason:
The nurse's priority in this situation is the client's blood pressure of 80/56 mm Hg. Opioid epidural analgesia can cause a drop in blood pressure, known as hypotension. Hypotension can be a significant concern during labor, as it may reduce blood flow to the placenta and compromise the baby's well-being. Therefore, it is crucial for the nurse to address this finding promptly to prevent any adverse effects on both the mother and the baby. The nurse may need to administer intravenous fluids, adjust the dosage of the opioid medication, or take other appropriate actions to raise the blood pressure to a safer level.
Choice B reason:
While profuse itching (choice B) can be a common side effect of opioids, it is not the nurse's priority in this situation. Itching, also known as pruritus, can be managed with antihistamines or other supportive measures, but it is not an immediate threat to the client's well-being.
Choice C reason:
The client reporting weakness of the lower extremities (choice C) is an expected side effect of epidural analgesia. Epidurals can cause temporary paralysis or weakness in the lower body due to the local anesthetic's effects on the nerves. While it's essential to monitor and support the client during this time, it is not the priority over the potentially dangerous drop in blood pressure.
Choice D reason:
A temperature of 38.2°C (100.8 F) (choice D) may indicate a fever, but it is not the nurse's priority in this specific situation of opioid epidural analgesia during labor. Fever during labor could have various causes, and the nurse should investigate and manage it appropriately. However, addressing the client's blood pressure takes precedence, as hypotension can have immediate and significant consequences.
