A nurse is reviewing BUN lab values for a dehydrated client. Which value should be reported to the provider?

In evaluating BUN (Blood Urea Nitrogen) lab values for a dehydrated client, it's important to recognize the implications of elevated BUN levels. A BUN value of 25 mg/dL is above the normal range, which typically falls between 7 and 20 mg/dL. This indicates a potential concern, especially when considering a dehydrated client, as dehydration can cause BUN levels to rise due to reduced renal perfusion and the body conserving water.

While a BUN of 20 mg/dL is at the upper limit of normal, it may not necessarily require immediate intervention or reporting. However, the value of 25 mg/dL is noteworthy and signifies a more pronounced elevation that could necessitate further evaluation and management by the healthcare provider. A BUN level of 30 mg/dL raises further concern and could indicate severe dehydration or potential kidney impairment. Reporting the value of 25 mg/dL appropriately alerts the provider to the need for reassessment of the client's hydration status and potential interventions to prevent further complications.
