Before applying a cord clamp, the nurse assesses the umbilical cord for vessels. The nurse expects to find: Select one:

Choice A Reason: Apical pulse of 148 beats per minute. This is not a finding that would support a diagnosis of RDS, but rather a normal finding for a newborn. A normal apical pulse for a newborn ranges from 120 to 160 beats per minute. A high pulse rate may indicate fever, infection, anemia, or dehydration. A low pulse rate may indicate hypothermia, hypoxia, or heart block.

Choice B Reason: Respiratory rate of 40 during sleep. This is not a finding that would support a diagnosis of RDS, but rather a normal finding for a newborn. A normal respiratory rate for a newborn ranges from 40 to 60 breaths per minute. A high respiratory rate may indicate respiratory distress, infection, or metabolic acidosis. A low respiratory rate may indicate respiratory depression, hypothermia, or narcotic exposure.

Choice C Reason: Skin color jaundiced. This is not a finding that would support a diagnosis of RDS, but rather a different condition called jaundice. Jaundice is a yellowish discoloration of the skin and mucous membranes caused by elevated levels of bilirubin in the blood. Bilirubin is a breakdown product of hemoglobin that is normally excreted by the liver and kidneys. Jaundice can occur in newborns due to immature liver function, increased red blood cell breakdown, or blood group incompatibility. Jaundice does not affect lung function or oxygenation.

Choice D Reason: Chest retractions. This is because chest retractions are a sign of respiratory distress that indicate increased work of breathing and reduced lung compliance. Chest retractions occur when the chest wall sinks in between the ribs or below the sternum during inhalation, creating a negative pressure that helps draw air into the lungs. RDS is a serious condition where the newborn's lungs are immature and lack sufficient surfactant, which is a substance that reduces surface tension and prevents alveolar collapse. RDS can cause respiratory distress, hypoxia, acidosis, and organ failure. It is more common in preterm infants, especially those born before 37 weeks' gestation.

Choice A Reason: Insulin needs decrease in the first trimester, but increase in the second trimester as the woman's body becomes more insulin-resistant. This is because this statement describes the typical patern of insulin requirements during pregnancy for women with pre-existing diabetes. Insulin needs decrease in the first trimester due to increased insulin production by the pancreas, increased insulin sensitivity by the tissues, and increased risk of hypoglycemia due to nausea and vomiting. Insulin needs increase in the second trimester due to increased levels of placental hormones such as human placental lactogen (hPL), which antagonize insulin action and cause insulin resistance.

Choice B Reason: Vascular disease that always accompanies diabetes slows fetal growth. This is an incorrect answer that makes a false and exaggerated claim about diabetes and fetal growth. Vascular disease does not always accompany diabetes, but it can be a complication of long-term or poorly controlled diabetes that affects blood vessels and circulation. Vascular disease can affect fetal growth by reducing placental perfusion and oxygen delivery, but it is not the only factor that influences fetal growth. Other factors include maternal nutrition, genetics, infections, or anomalies.

Choice C Reason: The risk of ketoacidosis decreases during the length of the pregnancy. This is an incorrect answer that contradicts the evidence and guidelines on diabetes and ketoacidosis during pregnancy. Ketoacidosis is a metabolic emergency where high levels of ketones accumulate in the blood due to insufficient insulin or excessive glucose utilization, which causes acidosis, dehydration, electrolyte imbalance, and coma. Ketoacidosis can occur in women with diabetes during pregnancy due to infection, stress, starvation, or inadequate insulin therapy. The risk of ketoacidosis does not decrease during the length of the pregnancy, but rather increases in the second and third trimesters due to increased insulin resistance and glucose production.

Choice D Reason: The baby is likely to have a congenital abnormality because of the uncontrolled diabetes. This is an incorrect answer that implies a negative and deterministic outcome for the baby. Congenital abnormalities are structural or functional defects that are present at birth, which can affect various organs or systems in the baby.

Congenital abnormalities can be caused by genetic or environmental factors, or a combination of both. Diabetes can increase the risk of congenital abnormalities, especially if the blood glucose levels are high during the first trimester, when organogenesis occurs. However, the risk of congenital abnormalities is not inevitable or predictable, and it can be reduced by maintaining good glycemic control before and during pregnancy.
