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?
WBC count 35,000/mm³ (9,000 to 30,000/mm³)
Glucose 35 mg/dL (greater than 40 to 45 mg/dL)
Bilirubin 14.0 mg/dL (1.0 to 12.0 mg/dL)
Platelet count 350,000/mm³ (150,000 to 300,000/mm³)
The Correct Answer is C
A. WBC count 35,000/mm³: Incorrect. While a slightly elevated WBC count can be observed in response to stress or minor trauma, such as a cephalohematoma, the value provided (35,000/mm³) is elevated but not specific to cephalohematoma.
B. Glucose 35 mg/dL: Incorrect. Hypoglycemia (glucose <40 mg/dL) is not directly related to cephalohematoma. The condition primarily affects bilirubin levels, not glucose.
C. Bilirubin 14.0 mg/dL: Correct. Cephalohematoma can lead to increased bilirubin levels as the accumulated blood breaks down, causing jaundice. This finding is consistent with the expected increase in bilirubin due to the condition.
D. Platelet count 350,000/mm³: Incorrect. A normal platelet count does not directly correlate with cephalohematoma. The platelet count given is within the normal range and is not indicative of the condition.

Correct Answer is B
Explanation
A. Hypotonicity.: Incorrect. Opioid withdrawal in newborns typically presents with hypertonicity (increased muscle tone) rather than hypotonicity.
B. Moderate tremors of the extremities.: Correct. Newborns experiencing opioid withdrawal often exhibit tremors or jitteriness in the extremities as part of the withdrawal symptoms.
C. Axillary temperature 36.1° C (96.9° F).: Incorrect. Opioid withdrawal does not usually cause hypothermia. Newborns with withdrawal may have a normal or slightly elevated temperature.
D. Excessive sleeping.: Incorrect. Excessive sleeping is not a typical symptom of opioid withdrawal; rather, newborns with withdrawal might experience irritability and difficulty sleeping.
Correct Answer is A
Explanation
A. Correct. Checking the identification badge of anyone who removes the baby from the room is an essential safety measure to ensure the baby is only handled by authorized personnel.
B. Incorrect. Sharing a photo of the baby on social media can pose security risks and is not recommended for newborn safety.
C. Incorrect. Allowing the baby to sleep unattended on the bed is unsafe due to the risk of falling or suffocation. The baby should always be in a safe sleep environment.
D. Incorrect. Nurses should follow protocols for transporting babies, which typically involve using a crib or bassinet rather than carrying the baby in their arms, to ensure safety.
