A nurse is reviewing the laboratory results of a newborn who is 32 hours old and has a cephalohematoma. Which of the following findings should the nurse expect as a result of this condition?
- A. WBC count of 35,000/mm² (normal range: 9,000 to 30,000/mm²).
- B. Glucose level of 35 mg/dL (normal range: greater than 40 to 45 mg/dL).
- C. Bilirubin level of 14.0 mg/dL (normal range: 1.0 to 12.0 mg/dL).
- D. Platelet count of 350,000/mm³ (normal range: 150,000 to 300,000/mm³).
Correct Answer: C
Rationale: A bilirubin level of 14.0 mg/dL is above the newborn normal range of 1.0 to 12.0 mg/dL. This indicates hyperbilirubinemia, commonly seen due to red blood cell breakdown in cephalohematoma.

- A. Hypotonicity.
- B. Moderate tremors of the extremities.
- C. Axillary temperature 36.1°C (96.9° F).

A nurse is reviewing a laboratory report for a client who is at 33 weeks of gestation and has preeclampsia. Which of the following laboratory results should the nurse expect?
- A. BUN level of 30 mg/dL (normal range: 10 to 20 mg/dL).
- B. Hemoglobin level of 9.9 g/dL (normal range: 11 to 16 g/dL).
- C. Serum uric acid level of 2.5 mg/dL (normal range: 2.7 to 7.3 mg/dL).
- D. Casual blood glucose level of 228 mg/dL (normal range: less than 200 mg/dL).
Correct Answer: A
Rationale: A BUN level of 30 mg/dL is above the normal range of 10 to 20 mg/dL. Elevated BUN is consistent with renal involvement in preeclampsia, which is caused by vascular constriction and reduced renal perfusion.
A nurse is teaching the parent of a newborn about car seat safety. Which of the following statements should the nurse make?
