Carol has persistent albuminuria, but her potassium is five point three. A medication plan without laboratory review and follow-up could create preventable harm. Do not initiate finerenone at that potassium level. Review the result, medicines, supplements, and clinical context, and arrange an appropriate response. When treatment changes, specify the laboratory test, the date, and who will act on the result. When a specialist visit is delayed, keep an interim owner of care. A prescription is not a completed handoff. Ask Carol to describe the next step in her own words. The HEART RESERVE approach is history, evidence, next action, and follow-up.
