A nurse in a clinic is planning care for a child who has ADHD and is taking atomoxetine.
Which of the following laboratory values should the nurse monitor?

Choice A rationale:

Administering 2 ounces of water to the newborn prior to the test is not a standard practice for newborn genetic screening. Newborns are typically screened for genetic disorders through a blood test, not by giving them water.

Choice B rationale:

This statement is incorrect. Newborn genetic screening is usually performed shortly after birth, not at 2 months old. Early screening allows for the early detection of certain genetic disorders, enabling timely interventions if needed.

Choice D rationale:

Drawing blood from the newborn's inner elbow is not specific guidance related to newborn genetic screening. Blood can be drawn from various sites, and healthcare providers choose the most appropriate site based on the newborn's condition and the required tests.

The correct answer is choice a. Maternal hypoglycemia.

Choice A rationale:

Maternal hypoglycemia can lead to decreased glucose availability for the fetus, which can result in fetal bradycardia due to reduced energy supply.

Choice B rationale:

Fetal anemia typically causes fetal tachycardia rather than bradycardia, as the fetus compensates for the lack of oxygen-carrying capacity by increasing the heart rate.

Choice C rationale:

Chorioamnionitis, an infection of the fetal membranes, usually causes fetal tachycardia due to the inflammatory response and fever.

Choice D rationale:

Maternal fever is more likely to cause fetal tachycardia rather than bradycardia, as the increased maternal temperature can lead to an increased fetal heart rate.
