When assessing a newborn 1 hour after birth, the nurse measures an axillary temperature of 95.8° F (35.4° C), an apical pulse of 114 beats per minute, and a respiratory rate of 60 breaths per minute. The nurse would identify which area as the priority?
Hypothermia.
Deficient fluid volume.
Impaired gas exchange.
Risk for infection.
The Correct Answer is A
Choice A reason:
Hypothermia is the priority area for this newborn because the axillary temperature of 95.8° F (35.4° C) is below the normal range of 97.7° F to 99.5° F (36.5° C to 37.5° C) for newborns1. Hypothermia can lead to complications such as hypoglycemia, metabolic acidosis, and impaired oxygen delivery2. The nurse should initiate interventions to warm the newborn, such as skin-to-skin contact, radiant warmer, or swaddling2.
Choice B reason:
Deficient fluid volume is not the priority area for this newborn because the apical pulse of 114 beats per minute is within the normal range of 100 to 160 beats per minute for newborns345. A low pulse rate can indicate dehydration or shock in newborns2. The nurse should monitor the newborn's fluid intake and output, weight, and signs of dehydration, such as dry mucous membranes, sunken fontanels, and poor skin turgor2.
Choice C reason:
Impaired gas exchange is not the priority area for this newborn because the respiratory rate of 60 breaths per minute is within the normal range of 30 to 60 breaths per minute for newborns345. A high or low respiratory rate can indicate respiratory distress or failure in newborns2. The nurse should assess the newborn's breath sounds, chest movements, oxygen saturation, and signs of respiratory distress, such as nasal flaring, grunting, retractions, and cyanosis2.
Choice D reason:
Risk for infection is not the priority area for this newborn because there is no evidence of infection in the vital signs or the question stem. However, newborns are vulnerable to infection due to their immature immune systems and exposure to pathogens during birth and aftercare2. The nurse should follow infection control measures, such as hand hygiene, aseptic technique, and cord care, and educate the parents on how to prevent infection at home2.

Correct Answer is B
Explanation
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 D
Explanation
Choice A reason:
A prolapsed umbilical cord occurs when the cord slips ahead of the presenting fetal part, potentially leading to cord compression and compromised fetal oxygenation. However, hypertonic contractions do not directly cause a prolapsed cord. Instead, factors such as premature rupture of membranes, abnormal fetal positioning, or excessive amniotic fluid (polyhydramnios) are more likely contributors to cord prolapse. Hypertonic contractions primarily affect uteroplacental circulation rather than fetal positioning.
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:
Hypertonic contractions reduce placental blood flow by limiting the relaxation phase between contractions. Normally, uterine contractions intermittently compress the spiral arteries supplying the placenta, but prolonged or excessively frequent contractions prevent adequate placental perfusion. This can lead to fetal hypoxia, acidosis, and distress, making it the most detrimental effect of oxytocin-induced hypertonic contractions.
