The student nurse learns that the hormone necessary for milk production is

Estrogen.

Prolactin.

Progesterone.

Lactogen.

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. Prolactin.

Choice A reason:

Estrogen. Estrogen is a hormone that plays a role in the development of the mammary glands and the ductal system during pregnancy. However, estrogen does not directly produce milk.

In fact, high levels of estrogen during pregnancy inhibit milk secretion by blocking prolactin. Therefore, estrogen is not the hormone necessary for milk production. • Choice B reason:

Prolactin. Prolactin is the hormone responsible for the production of breast milk. Prolactin is secreted by the pituitary gland in response to suckling or nipple stimulation. Prolactin levels rise during pregnancy and peak after delivery, when the sudden drop in estrogen and progesterone allows prolactin to take over and initiate lactation. Therefore, prolactin is the hormone necessary for milk production. • Choice C reason:

Progesterone. Progesterone is a hormone that also contributes to the development of the mammary glands and the alveoli during pregnancy. However, like estrogen, progesterone does not directly produce milk. Progesterone also inhibits milk secretion by blocking prolactin during pregnancy. Therefore, progesterone is not the hormone necessary for milk production. •

Choice D reason:

Lactogen. Lactogen is not a hormone, but a general term for any substance that stimulates lactation. There are different types of lactogens, such as human placental lactogen (hPL), which is produced by the placenta during pregnancy and has some lactogenic effects on the mammary glands. However, hPL is not the main hormone responsible for milk production. That role belongs to prolactin. Therefore, lactogen is not the hormone necessary for milk production.

Correct Answer is C

Explanation

Choice A reason:

While positioning is important for comfort during labor, addressing the immediate urge to push takes priority. Panting during contractions is the appropriate action.

Choice B reason:

Although observing for crowning is important when the client is close to delivery, the nurse should first intervene to address the client's urge to push since the client is only 7 cm dilated.

Choice C reason:

When a laboring client feels the urge to push but is not yet fully dilated (10 cm), encouraging her to pant can help reduce the urge to push and avoid complications, such as cervical swelling or tearing. This breathing technique helps the client delay pushing until full dilation and readiness of the cervix.
Choice D reason:

Assisting the client to the bathroom would not be appropriate at this stage of labor because the urge to push could lead to unsafe delivery outside the appropriate setting, and movement could increase discomfort or risks.

A. It produces a prolapsed cord. B. It increases maternal renal blood flow. C. It decreases maternal blood pressure. D. There is a reduction of placental blood flow.

Correct Answer is A

Explanation

Choice A reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it causes a reduction of placental blood flow. Placental blood flow is essential for delivering oxygen and nutrients to the fetus and removing waste products. Hypertonic contractions are too frequent, too long, or too strong, and they can reduce the time for the placenta to refill with blood between contractions. This can lead to fetal hypoxia, acidosis, and distress.

Choice B reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it produces a prolapsed cord. This is incorrect because a prolapsed cord is not caused by hypertonic contractions, but by other factors such as a low-lying placenta, a premature rupture of membranes, a small or preterm fetus, or an abnormal presentation. A prolapsed cord occurs when the umbilical cord slips through the cervix and into the vagina before or during delivery. This can compress the cord and cut off the blood supply to the fetus, resulting in fetal bradycardia and possible death.

Choice C reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it increases maternal renal blood flow. This is incorrect because hypertonic contractions do not affect maternal renal blood flow directly. Maternal renal blood flow is influenced by factors such as maternal blood pressure, hydration, cardiac output, and renal function. Hypertonic contractions may cause maternal dehydration, which can reduce renal blood flow, but this is not a direct effect of oxytocin stimulation.

Choice D reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it decreases maternal blood pressure. This is incorrect because hypertonic contractions do not cause maternal hypotension, but rather hypertension. Hypertension is a common side effect of oxytocin stimulation, as oxytocin causes vasoconstriction and increases the sensitivity of the vascular smooth muscle to catecholamines. Hypertension can lead to complications such as preeclampsia, eclampsia, and placental abruption.
