Assessment findings of a 4-hour-old newborn include an axillary temperature of 96.8° F (35.8° C), heart rate of 150 beats/minute with a soft murmur, irregular respiratory rate at 64 breaths/minute, jitteriness, hypotonia, and a weak cry.Based on these findings, which action should the nurse implement?

Choice A rationaleThe symptoms of jitteriness, hypotonia, weak cry, and low temperature can indicate hypoglycemia in a newborn. Obtaining a heel stick blood glucose level is crucial to confirm the diagnosis and provide appropriate treatment.Choice B rationaleWhile keeping the infant warm is important, it does not address the underlying issue of potential hypoglycemia, which needs to be identified and treated promptly.Choice C rationalePlacing a pulse oximeter on the heel assesses oxygen saturation, which is not directly related to the symptoms described. The primary concern here is glucose level, not oxygen saturation.Choice D rationaleDocumenting the findings is important but does not provide immediate intervention for potential hypoglycemia, which requires urgent glucose level assessment and treatment if necessary. .
