Final answer:
The nurse should document the specific error of administering 80 mg of Furosemide instead of the prescribed 40 mg in the incident report for clarity and accuracy.
Step-by-step explanation:
The nurse should document D. Furosemide 80 mg given to the client instead of 40 mg on an incident report. This statement is the most accurate and complete, as it specifies both the medication given and the discrepancy with the prescribed dose. It is crucial in a clinical setting to document any medication errors thoroughly for the safety of the patient and to make sure that appropriate follow-up actions are taken.
