Final answer:
The abnormal lab result that should be reported to the provider is the WBC count of 3,500/mm3, indicating possible leukopenia, which can be a side effect of carbamazepine.
Step-by-step explanation:
Lab Result Analysis for a Patient on Carbamazepine
In the context of a client who is taking carbamazepine for a seizure disorder, a nurse should report abnormal laboratory findings to the provider. The options presented are:
- Potassium 4.1 mEq/L
- 24-hour urine glucose 300 mg/day
- Carbamazepine level 7 mcg/mL
- WBC 3,500/mm3
Among these, the WBC (white blood cell) count of 3,500/mm3 is a critical finding because it indicates leukopenia, which may be a side effect of carbamazepine and could potentially lead to an increased risk of infection. The result falls below the normal lower range for adult white blood cells (typically 4,500 to 11,000/mm3). The other values, such as potassium levels and 24-hour urine glucose, are within normal ranges. A carbamazepine level of 7 mcg/mL is considered therapeutic and not necessarily a cause for concern unless it is associated with signs of toxicity or side effects.
