I have edited the text according to your instructions. Here is the edited text and the answer for the question:

The patient is having fetal heart rate decelerations. An amnioinfusion has been ordered for the patient to alleviate the decelerations. The nurse understands that the type of decelerations that will be alleviated by amnioinfusion is:
Select one:

Late decelerations.

Moderate decelerations.

Variable decelerations.

Early decelerations.

Answer and Explanation

The Correct Answer is C

Choice A Reason: Late decelerations. This is an incorrect answer that refers to a diﬀerent type of fetal heart rate patern that indicates uteroplacental insufficiency, which can reduce blood ﬂow and oxygen delivery to the fetus. Late decelerations are characterized by gradual decreases in fetal heart rate that begin after the peak of uterine contractions and return to baseline after the end of contractions. Amnioinfusion is not eﬀective for late decelerations, as it does not address the underlying cause of uteroplacental insufficiency, which may be due to maternal hypertension, diabetes, preeclampsia, or placental abruption.

Choice B Reason: Moderate decelerations. This is an incorrect answer that refers to a non-existent type of fetal heart rate patern, as there is no such term as moderate decelerations. The term moderate refers to the category of fetal heart rate variability, which is a measure of the ﬂuctuations in fetal heart rate around the baseline. Moderate variability indicates normal fetal oxygenation and well-being, while absent or minimal variability indicates fetal hypoxia or distress.

Choice C Reason: Variable decelerations. This is because variable decelerations are a type of fetal heart rate patern that indicates cord compression, which can reduce blood ﬂow and oxygen delivery to the fetus. Variable decelerations are characterized by abrupt decreases in fetal heart rate that vary in onset, depth, and duration, and do not have a consistent relationship with uterine contractions. Amnioinfusion is a procedure that involves infusing saline or lactated Ringer's solution into the amniotic cavity through a transcervical catheter, which can relieve cord compression by increasing the volume of amniotic ﬂuid and cushioning the cord. Amnioinfusion can improve fetal oxygenation and reduce variable decelerations.

Choice D Reason: Early decelerations. This is an incorrect answer that refers to a diﬀerent type of fetal heart rate patern that indicates head compression, which can stimulate the vagus nerve and slow down the fetal heart rate. Early decelerations are characterized by gradual decreases in fetal heart rate that begin with the onset of uterine contractions and return to baseline with the end of contractions. Early decelerations are benign and do not require intervention, as they reﬂect normal fetal head descent and progress of labor. Amnioinfusion is not indicated for early decelerations, as it does not aﬀect head compression or vagal stimulation.

Correct Answer is A

Explanation

Choice A Reason: Grunting and nasal ﬂaring. These are signs of respiratory distress in newborns, which indicate that their oxygenation needs are not being met. Grunting and nasal ﬂaring. This is because grunting and nasal ﬂaring are signs of respiratory distress in newborns, which indicate inadequate oxygenation and ventilation. Grunting is a noise made by the newborn when exhaling, which reﬂects an atempt to keep the alveoli open and increase lung volume.

Nasal ﬂaring is a widening of the nostrils when inhaling, which reﬂects an eﬀort to reduce airway resistance and increase airﬂow.

Choice B Reason: Acrocyanosis. This is not a sign of respiratory distress in newborns, but rather a common condition called acrocyanosis. Acrocyanosis means bluish discoloration of the hands and feet due to poor peripheral circulation in response to cold exposure or stress. It does not aﬀect oxygenation or ventilation and usually disappears within 24 to 48 hours after birth.

Choice C Reason: Abdominal breathing. This is not a sign of respiratory distress in newborns, but rather a normal patern of breathing for them. Abdominal breathing means that the newborn's abdomen rises and falls with each breath, which reﬂects the use of the diaphragm as the primary respiratory muscle.

Choice D Reason: Respiratory rate of 54 breaths/minute. This is not a sign of respiratory distress in newborns, but rather a normal range of respiratory rate for them. A normal respiratory rate for a newborn ranges from 40 to 60 breaths per minute.

A. Vascular spider veins. B. Linea nigra. C. Melasma. D. Striae gravidarum.

Correct Answer is B

Explanation

Choice A Reason: Vascular spider veins. This is an incorrect answer that refers to a diﬀerent skin change that occurs during pregnancy, which aﬀects the blood vessels, not the pigment. Vascular spider veins are small red or purple clusters of blood vessels that appear on the skin, especially on the face, neck, chest, or legs. Vascular spider veins are caused by increased blood volume and hormonal changes, which dilate and rupture the capillaries. Vascular spider veins are harmless and usually disappear after delivery.

Choice B Reason: Linea nigra. This is because linea nigra is a term that refers to a darkened vertical line that appears on the abdomen during pregnancy, which runs from the umbilicus to the pubis. Linea nigra is caused by increased production of melanin, which is a pigment that gives color to the skin and hair. Linea nigra is more common and noticeable in women with darker skin tones, and it usually fades after delivery.

Choice C Reason: Melasma. This is an incorrect answer that refers to a diﬀerent skin change that occurs during pregnancy, which aﬀects the pigment, but not in a linear patern. Melasma is a term that refers to patches of brown or gray-brown discoloration that appear on the face, especially on the forehead, cheeks, nose, or upper lip. Melasma is also caused by increased production of melanin, but it is inﬂuenced by sun exposure and genetic factors. Melasma is also known as chloasma or the mask of pregnancy, and it may persist after delivery.

Choice D Reason: Striae gravidarum. This is an incorrect answer that refers to a diﬀerent skin change that occurs during pregnancy, which aﬀects the connective tissue, not the pigment. Striae gravidarum are stretch marks that appear on the skin, especially on the abdomen, breasts, hips, or thighs. Striae gravidarum are caused by rapid growth and stretching of the skin, which damage the collagen and elastin fibers. Striae gravidarum are initially red or purple, but they fade to white or silver after delivery.
