A nurse accidentally administers metformin instead of metoprolol to a client. Which of the following actions should the nurse take?

A. Monitor the client’s thyroid function levels is not relevant to the administration of metformin, as metformin does not affect thyroid function. B. Collect the client’s uric acid level is not necessary in this context, as metformin does not typically impact uric acid levels. C. Obtain the client’s HDL level is not relevant to the administration of metformin, as metformin does not directly affect HDL levels. D. Check the client’s glucose level is the most appropriate action, as metformin is an antidiabetic medication that lowers blood glucose levels. Monitoring the client’s glucose level will help assess the impact of the incorrect medication administration and guide further treatment.
