What should the nurse do upon finding a serum digoxin level of 0.8 ng/mL in a patient?

A serum digoxin level of 0.8 ng/mL falls within the typical therapeutic range for digoxin, which is generally considered to be between 0.5 and 2.0 ng/mL. When a nurse finds a serum digoxin level within this acceptable range, the appropriate action is to document the laboratory result as part of the patient's medical records.

Maintaining accurate documentation is crucial in patient care as it helps ensure continuity of care, provides a record of the patient’s status, and can inform other healthcare providers about the patient's current management plan. Furthermore, since the level is not indicative of toxicity, further actions such as contacting the healthcare provider, repeating the test, or monitoring for signs of toxicity are unnecessary at this time, as the level does not suggest any immediate concerns.
