A nurse is teaching a newly licensed nurse about the uses of ultrasonography in the first trimester of pregnancy. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

The correct answer is choice B: Administer a bolus infusion of lactated Ringer’s.

Choice A rationale:

Positioning the client in a knee-chest position is not the standard intervention for maternal hypotension following epidural placement. This position is more commonly associated with cord prolapse or to relieve pressure on the vena cava.

Choice B rationale:

Administering a bolus infusion of lactated Ringer’s is the correct action. Hypotension during epidural analgesia is treated with additional intravenous boluses of crystalloid solution. This helps to increase the circulating blood volume and counteract the vasodilation caused by the epidural.

Choice C rationale:

Terbutaline is a medication used to relax the uterus and prevent premature labor, not for treating hypotension.

Choice D rationale:

Applying oxygen via a nonrebreather face mask at 2 L/min is not the primary treatment for maternal hypotension. Oxygen may be used as a supportive measure if there is evidence of fetal distress or maternal hypoxemia, but the first line of treatment for hypotension is fluid administration.

Choice A rationale:
Preterm gestational age is not indicated by the presence of breast tissue with a flat areola and no bud. Preterm newborns may have immature breast tissue, but it does not manifest as a flat areola with no bud.

Choice B rationale:
Decreased maternal hormones during pregnancy would result in less developed breast tissue in the newborn, but it wouldn't present as a flat areola with no bud. Instead, the breast tissue may be small and less pronounced.

Choice C rationale:
Congenital anomaly refers to a birth defect or malformation that occurs during fetal development. In this case, the flat areola with no bud suggests an abnormality in the development of the breast tissue. Further assessment and evaluation may be required to determine the exact nature of the anomaly.

Choice D rationale:
Ambiguous secondary sex characteristics would involve the presence of characteristics that are not clearly male or female. The described breast tissue does not fit this category, as it is specifically described as having a flat areola with no bud, which is more indicative of a congenital anomaly.
