The nurse checks the blood sugar of a 2 hour old newborn, and the glucometer reading is 32 mg/dl. Which action should the nurse take next?

Choice A reason:

This statement is incorrect because special lights are used to treat jaundice, not PKU. Jaundice is a condition that causes yellowing of the skin and eyes due to high levels of bilirubin in the blood. Bilirubin is a waste product that is normally removed by the liver. Special lights help break down bilirubin so that it can be excreted from the body.

Choice B reason:

This statement is correct because PKU is a genetic disorder that can be corrected by diet. PKU is caused by a lack of an enzyme that breaks down phenylalanine, an amino acid found in protein-rich foods. Phenylalanine can build up in the blood and cause brain damage and other health problems if not treated. A diet that is low in phenylalanine and high in a special formula can prevent these complications.

Choice C reason:

This statement is correct because sometimes the test is repeated in the doctor's office at the 2-week check-up. The PKU test is done one to three days after birth, but it may not be accurate if the baby has not had enough protein in their diet before the test. A repeat test may be needed to confirm or rule out PKU.

Choice D reason:

This statement is incorrect because the baby must take formula or breast milk after the test is done, not before. The test measures the level of phenylalanine in the blood, which will be higher if the baby has eaten protein-rich foods. The test should be done after the baby has fasted for at least two hours.

Choice A:

Temperature is not a finding that the nurse should report to the provider. The normal range for temperature in newborns is 36.5 to 37 degrees Celsius axillary. The question does not provide the temperature of the newborn, but it does not indicate any signs of hypothermia or hyperthermia.

Choice B:

Respiratory findings are findings that the nurse should report to the provider. The newborn has mild grunting, nasal flaring, and intermittent retractions, which are signs of respiratory distress. These could indicate a problem with lung development, infection, or congenital heart disease.

Choice C:

Serum glucose is a finding that the nurse should report to the provider. The normal range for blood glucose in newborns is above 40 mg/dL. The question does not provide the serum glucose level of the newborn, but it could be low due to factors such as prematurity, maternal diabetes, or sepsis.

Choice D:

Hematocrit is a finding that the nurse should report to the provider. The normal range for hematocrit in newborns is 42% to 65%. The question does not provide the hematocrit level of the newborn, but it could be high due to polycythemia or low due to anemia or hemorrhage.

Choice E:

White blood cell count is not a finding that the nurse should report to the provider. The normal range for white blood cell count in newborns is 9,000 to 30,000/mm3. The question does not provide the white blood cell count of the newborn, but it does not indicate any signs of infection or inflammation.

Choice F:

Hemoglobin is a finding that the nurse should report to the provider. The normal range for hemoglobin in newborns is 14 to 24 g/dL. The question does not provide the hemoglobin level of the newborn, but it could be high due to polycythemia or low due to anemia or hemorrhage.

Choice G:

Heart rate is a finding that the nurse should report to the provider. The normal range for heart rate in newborns is 85 to 190 beats per minute when awake. The question does not provide the heart rate of the newborn, but it could be high due to stress, pain, fever, or hypoxia, or low due to bradycardia or cardiac arrest.
