Final answer:
The nurse should report the platelet count of 150,000/mm³ to the provider, as carbamazepine can cause thrombocytopenia. Other laboratory values provided are within normal ranges and not typically a concern.
Step-by-step explanation:
The laboratory finding that a nurse should report to the provider for a client taking carbamazepine for a seizure disorder is c) Platelet count of 150,000/mm³. Carbamazepine can cause blood dyscrasias such as thrombocytopenia (low platelet count), which can increase the risk of bleeding. Since a platelet count of 150,000/mm³ is at the lower end of the normal range (150,000-450,000/mm³), this finding requires monitoring to ensure that the platelet count does not fall further, which could lead to significant clinical concerns.
Options a) Sodium level of 140 mEq/L, b) White blood cell count of 8000/mm³, and d) Blood glucose level of 110 mg/dL are within normal ranges and are not typically concerning in a patient taking carbamazepine. For example, the normal sodium level is 135-145 mEq/L, a normal white blood cell count is 4500-11,000/mm³, and a normal fasting blood glucose level ranges from 70 to 99 mg/dL. Thus, these values do not suggest an adverse effect of the medication that would warrant notification of the healthcare provider.
In the clinical context, constant monitoring of laboratory results is essential when a patient is on medication like carbamazepine, as it can lead to various side effects affecting the blood. Any significant deviation from normal values, especially in platelet count, white blood cell count, and blood glucose levels, can indicate a potential complication that requires immediate attention.
