A nurse is reviewing the laboratory results of a newborn that is 4 hr old. Which of the following findings should the nurse identify as the priority?

Choice A rationale:

An apical pulse of 130/min in a newborn is within the normal range. The normal heart rate for a newborn is generally between 110 to 160 beats per minute (bpm). As the newborn's heart rate falls within this range, the nurse should document it as an expected finding and continue routine monitoring.

Choice B rationale:

Calling the neonatologist to assess the newborn for an apical pulse of 130/min is not warranted as it is a normal finding. The nurse should only notify the neonatologist if there are abnormal vital signs or concerning clinical signs.

Choice C rationale:

Asking another nurse to verify the heart rate is unnecessary in this scenario. The nurse can independently measure the apical pulse and document the finding as long as it falls within the normal range for newborns.

Choice D rationale:

Preparing the newborn for transport to the Neonatal Intensive Care Unit (NICU) is not indicated for a normal apical pulse rate. Transporting a newborn to the NICU is typically reserved for critical or unstable conditions. In this case, the normal heart rate of 130/min does not warrant NICU transport.

Choice A rationale:

The liver's job related to bilirubin is not changing conjugated bilirubin to unconjugated. Conjugated bilirubin is the water-soluble form of bilirubin that is excreted in bile and urine. Unconjugated bilirubin, on the other hand, is the fat-soluble form, which is transported to the liver and conjugated to become water-soluble. The conversion goes from unconjugated to conjugated, not the other way around.

Choice B rationale:

The liver's job related to bilirubin is not the synthesis of vitamin K. The liver is responsible for synthesizing clotting factors, including factors II (prothrombin), VII, IX, and X, but not vitamin K itself. Vitamin K is obtained from dietary sources or supplements and is essential for blood clotting.

Choice C rationale:

This choice is the correct answer. The liver's primary function related to bilirubin is changing unconjugated bilirubin to conjugated bilirubin. As mentioned earlier, unconjugated bilirubin is produced from the breakdown of heme in old red blood cells, and it needs to be processed in the liver to become water-soluble and eventually excreted in bile and urine.

Choice D rationale:

The liver's job related to bilirubin does not involve the removal of meconium. Meconium is the first stool passed by a newborn, and its elimination is unrelated to the liver's function in processing bilirubin.
