If a medication is to be adjusted based on potassium levels, who should be called?

The physician should be called for medication adjustments based on potassium levels because they are responsible for prescribing medications and assessing the patient's overall clinical picture. In the case of abnormal potassium levels, it is the physician's role to evaluate the situation, determine the appropriate course of action, and make any necessary changes to the medication regimen. Adjusting medication, especially those affected by electrolyte levels like potassium, requires clinical judgment that falls under the physician’s scope of practice.

While pharmacists are valuable resources for medication information and recommendations, they typically do not make decisions about prescribing or adjustments without a physician's directive. Nursing supervisors can provide support and guidance for nursing staff, but they are not the decision-makers in terms of medication changes. The patient’s family is involved for support and communication but does not have the authority to make clinical decisions regarding medication management.
