One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because
A. It produces a prolapsed cord.
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.
B. It increases maternal renal blood flow.
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.
C. It decreases maternal blood pressure.
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.
D. There is a reduction of placental blood flow.
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.

A nurse is caring for a newborn and observes signs of diaphoresis, jitteriness, and lethargy. Which of the following actions should the nurse take?
A. Obtain blood glucose by heel stick.
Obtaining blood glucose by heel stick is the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. These signs are suggestive of hypoglycemia, which is a common and potentially serious condition in newborns. Hypoglycemia can result from various causes, such as maternal diabetes, prematurity, intrauterine growth restriction, or perinatal stress. A heel stick is a simple and quick method to obtain blood samples from newborns for glucose testing.
B. Initiate phototherapy.
Initiating phototherapy is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Phototherapy is used to treat hyperbilirubinemia, which is a condition characterized by high levels of bilirubin in the blood. Hyperbilirubinemia can cause jaundice, which is a yellowish discoloration of the skin and eyes. Jaundice does not typically cause diaphoresis, jitteriness, or lethargy in newborns.
C. Monitor the newborn's blood pressure.
Monitoring the newborn's blood pressure is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Blood pressure measurement is not routinely performed in healthy newborns. Blood pressure may be indicated in newborns who have signs of cardiovascular compromise, such as cyanosis, tachycardia, or poor perfusion. Diaphoresis, jitteriness, and lethargy are not specific signs of cardiovascular compromise in newborns.
D. Place the newborn in a radiant warmer.
Placing the newborn in a radiant warmer is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. A radiant warmer is a device that provides heat to maintain the newborn's body temperature. A radiant warmer may be used for newborns who are at risk of hypothermia, such as those who are premature, low birth weight, or have cold stress. Diaphoresis, jitteriness, and lethargy are not specific signs of hypothermia in newborns.

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?
A. Hypothermia.
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.
B. Deficient fluid volume.
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.
C. Impaired gas exchange.
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.
D. Risk for infection.
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 system 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.

During a vaginal delivery, the first thing a nurse must ensure when the head comes out is that the midwife or doctor checks that
A. The cord is still pulsating.
The cord is still pulsating. This is not the first thing a nurse must ensure when the head comes out because the cord normally pulsates until the placenta is delivered. The pulsation indicates that the cord is still functioning and transferring blood and oxygen between the baby and the placenta. However, this does not mean that the cord is free from any complications that could endanger the baby's life, such as a nuchal cord (a cord wrapped around the neck) or a prolapsed cord (a cord that slips out before the baby). •
B. The cord is intact.
The cord is intact. This is not the first thing a nurse must ensure when the head comes out because the cord is usually intact until it is clamped and cut after the delivery of the baby. The cord can be ruptured by excessive traction or twisting, which can cause bleeding and shock in the baby. However, this is a rare occurrence and does not pose an immediate threat to the baby's life as long as the cord is still attached to the placenta. •
C. No part of the cord is encircling the baby's neck.
No part of the cord is encircling the baby's neck. This is the correct answer because a nuchal cord can cause compression of the cord and reduce blood flow and oxygen to the baby, leading to fetal distress, hypoxia, and brain damage. A nuchal cord occurs in about 10 to 30 percent of deliveries and can be detected by feeling for a loop of cord around the neck as the head emerges. If a nuchal cord is present, it should be gently slipped over the head or clamped and cut before delivery of the shoulders. •
D. The cord is still attached to the placenta.
The cord is still attached to the placenta. This is not the first thing a nurse must ensure when the head comes out because the cord is always attached to the placenta until it separates from the uterine wall and is expelled after the delivery of the baby. The placenta provides nourishment and oxygen to the baby through the cord. However, this does not mean that the cord is free from any complications that could endanger the baby's life, such as a nuchal cord or a prolapsed cord.
