A nurse is teaching about car seat safety to the parents of a newborn who was delivered at 38 weeks of gestation. Which of the following statements by a parent indicates an understanding of the teaching?

Rationale:

A. A WBC count of 11,000/mm3 is slightly elevated but may be within normal limits, as the normal range for WBC count can vary slightly depending on the laboratory. It is not typically concerning during pregnancy.

B. A hematocrit of 37% is within the normal range for pregnancy (37% to 47%) and does not require immediate reporting to the provider.

C. A fasting blood glucose level of 180 mg/dL is significantly elevated and indicates hyperglycemia, which may be indicative of gestational diabetes mellitus or pre-existing diabetes. This finding should be reported to the provider for further evaluation and management.

D. A creatinine level of 0.9 mg/dL is within the normal range (0.5 to 1 mg/dL) and does not require immediate reporting to the provider.

Rationale:

A. An apneic episode less than 15 seconds may be considered within normal limits for a newborn and does not necessarily indicate a decline in status.

B. Fine crackles may indicate fluid in the lungs but are not specific to a decline in the newborn's status.

C. An oxygen saturation of 89% indicates hypoxemia, which is a significant concern and suggests respiratory compromise. It indicates a decline in the newborn's status and requires immediate intervention to improve oxygenation.

D. Nasal flaring is a sign of respiratory distress but may not be as concerning as a low oxygen saturation level in this context. It indicates increased work of breathing but does not provide direct information about oxygenation status.
