A nurse is caring for a client who is in labor and has an external fetal monitor. The nurse observes late decelerations on the monitor strip and interprets them as indicating which of the following?
Uteroplacental insufficiency.
Umbilical cord compression.
Maternal bradycardia.
Fetal head compression.
The Correct Answer is A
Choice A reason:
Uteroplacental insufficiency is a condition where the placenta cannot deliver enough oxygen and nutrients to the fetus. This can cause fetal hypoxia and distress, which can be detected by late decelerations on the fetal heart rate monitor. Late decelerations are defined as a decrease in the fetal heart rate that begins after the peak of the contraction and returns to baseline after the contraction ends. This indicates that the fetus is not tolerating the reduced blood flow during the contractions and needs immediate intervention. • Choice B reason:
Umbilical cord compression is a condition where the umbilical cord is squeezed or twisted, reducing the blood flow and oxygen to the fetus. This can cause variable decelerations on the fetal heart rate monitor. Variable decelerations are defined as a decrease in the fetal heart rate that varies in timing, shape, and duration, and may or may not be associated with contractions. This indicates that the fetus is experiencing intermittent or sustained cord compression and may need repositioning or other interventions. • Choice C reason:
Maternal bradycardia is a condition where the mother's heart rate is slower than normal, usually less than 60 beats per minute. This can cause reduced blood flow and oxygen to the placenta and the fetus, but it does not cause late decelerations on the fetal heart rate monitor. Maternal bradycardia can be caused by various factors, such as medications, hypothermia, hypothyroidism, or vagal stimulation. It may need treatment depending on the cause and severity. • Choice D reason:
Fetal head compression is a condition where the fetal head is pressed against the cervix or the pelvic floor during labor, stimulating the vagus nerve and slowing down the fetal heart rate. This can cause early decelerations on the fetal heart rate monitor. Early decelerations are defined as a decrease in the fetal heart rate that begins with the onset of the contraction and returns to baseline with the end of the contraction. This indicates that the fetus is descending in the birth canal and is usually a normal and benign finding.

Correct Answer is A
Explanation
Choice A reason:
Choice A is the correct answer because the number of wet diapers a newborn has per day is a reliable indicator of effective breastfeeding. When a baby is breastfeeding well and getting enough milk, they will have an adequate number of wet diapers, typically at least six to eight per day. The frequent wet diapers indicate that the baby is adequately hydrated, and their body is eliminating waste products as expected.
Choice B reason:
Choice B, having at least one breast milk stool every 24 hours, is not the most reliable indicator of effective breastfeeding, although it is an important consideration. The frequency of bowel movements can vary among breastfed infants, and some babies may have several bowel movements a day, while others may have fewer, even skipping a day. The number of wet diapers is a more consistent measure of sufficient milk intake.
Choice C reason:
Choice C, sleeping for 6 hours at a time between feedings, is not an accurate indicator of effective breastfeeding in a 4-day-old newborn. Newborns typically feed frequently, at least 8-12 times in 24 hours, and they may not sleep for extended periods between feedings at this age. Frequent feeding is essential for establishing a good milk supply and ensuring the baby receives enough nutrients.
Choice D reason:
Choice D, gaining 1 to 2 ounces per week, is also not the most reliable indicator of effective breastfeeding in the early days after birth. Weight gain can vary significantly in newborns, and a 4-day-old baby might not show the expected 1 to 2 ounces per week gain yet. Moreover, weight gain can be affected by factors other than breastfeeding, such as birth weight, initial fluid loss, and individual growth patterns.
Correct Answer is A
Explanation
The correct answer is: a. Hyperbilirubinemia.
Choice A: Hyperbilirubinemia
Reason: Hyperbilirubinemia in newborns is often caused by the increased breakdown of red blood cells, which have a shorter lifespan in neonates. This breakdown produces bilirubin, a yellow pigment that can accumulate in the blood, leading to jaundice. The liver of a newborn is not fully mature and may not be able to process and excrete bilirubin efficiently, resulting in hyperbilirubinemia.
Choice B: Respiratory Distress Syndrome
Reason: Respiratory Distress Syndrome (RDS) is primarily caused by a deficiency of surfactant in the lungs, which is more common in premature infants. It is not directly related to the lifespan of red blood cells. Symptoms include rapid, shallow breathing and a bluish color due to lack of oxygen.
Choice C: Polycythemia
Reason: Polycythemia is characterized by an abnormally high concentration of red blood cells. It is often due to factors like delayed cord clamping or maternal diabetes, rather than the decreased lifespan of red blood cells. Polycythemia can lead to increased blood viscosity and complications such as sluggish blood flow.
Choice D: Transient Tachypnea
Reason: Transient Tachypnea of the Newborn (TTN) is a respiratory condition caused by delayed clearance of fetal lung fluid. It typically resolves within a few days and is not related to the lifespan of red blood cells. Symptoms include rapid breathing and grunting.
