The nurse is preparing to administer phytonadione to a newborn. Which statement made by the parents indicates understanding why the nurse is administering this medication?

Choice A rationale

Caput succedaneum is a benign swelling of the soft tissues of the scalp that crosses suture lines and does not require drainage.

Choice B rationale

Cephalhematoma is a collection of blood between the skull and periosteum that does not cross suture lines; it may contribute to jaundice as it is reabsorbed by the body.

Choice C rationale

While cephalhematoma usually resolves without intervention, it is important to monitor for potential complications, including jaundice, due to the breakdown of red blood cells.

Choice D rationale

Caput succedaneum typically resolves on its own without intervention, as the fluid is gradually absorbed by the body over time.

Acidemia: Acidemia refers to an abnormal acidity in the blood (pH < 7.35). Prolonged abnormal FHR patterns can indicate insufficient oxygen delivery to the fetus, leading to anaerobic metabolism and the production of lactic acid, causing acidemia. The normal fetal pH is around 7.30-7.35.

Hypoxemia: Hypoxemia is a reduced level of oxygen in the blood. Abnormal FHR patterns may signal that the fetus is not receiving adequate oxygen, potentially due to cord compression, placental insufficiency, or other factors affecting oxygen transfer. Normal oxygen saturation for a fetus is generally around 30-70%.

Hypoxia: Hypoxia is a condition where there is insufficient oxygen available to meet the metabolic needs of the fetus. Abnormal FHR patterns can indicate ongoing or impending hypoxia, which can lead to severe fetal distress and compromise. It is crucial to monitor and address such conditions promptly.

Rationale for Incorrect Answers:

Hypoglycemia: Hypoglycemia refers to low blood glucose levels (typically < 45 mg/dL in newborns). Abnormal FHR patterns are not directly associated with changes in glucose metabolism. Rather, hypoglycemia in neonates is often related to maternal diabetes, prematurity, or other metabolic disturbances.

Meconium Stool: Meconium-stained amniotic fluid is a possible indicator of fetal distress but is not a direct result of abnormal FHR patterns. Meconium passage may be associated with post-term pregnancy, fetal hypoxia, or other factors, but the direct consequences of abnormal FHR patterns are more specifically related to oxygenation and acid-base status.

Maternal Hypotension: Maternal hypotension, or low blood pressure (typically < 90/60 mm Hg), is a maternal condition that can affect fetal well-being if severe and prolonged. However, it is not a direct result of abnormal FHR patterns. Instead, maternal hypotension can contribute to abnormal FHR by impairing uteroplacental perfusion.
