## Question

Categorize each medication-list discrepancy by the type of reconciliation problem it represents.

**1.** Methotrexate is verified as every Tuesday, but the new list says once daily

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

**2.** The current bottle says metoprolol tartrate 25 mg twice daily, but the new list says 50 mg twice daily

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

**3.** Acetaminophen and Tylenol are listed as separate scheduled medications

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

**4.** Lisinopril 20 mg daily appears on two active lines

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

**5.** A prednisone taper completed last month remains marked active

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

**6.** A completed 5-day nitrofurantoin course remains marked active

Select a category
Stale entry
Duplicate entry
Dose or frequency mismatch

## Explanation

Medication reconciliation identifies unexplained differences in dose or frequency, duplicate entries, and medications that should no longer remain active.

## In-depth explanation

Quick answer
Sort the six entries into dose or frequency mismatch, duplicate entry, or stale entry.

Why this is correct
AHRQ recommends obtaining and verifying the medication history, comparing it with current orders, and resolving unintended differences. Naming the discrepancy helps the team ask the right follow-up question without guessing the intended regimen.

Easy analogy or mental picture
Think of the medication list as inventory: the wrong amount is a mismatch, the same item counted twice is a duplicate, and an item already discarded is stale.

Memory hook
Mismatch, duplicate, stale: identify first, resolve second.

NCLEX decision rule
Classify only what the evidence supports. The category describes the discrepancy; it does not authorize the nurse to choose a replacement dose or delete an order independently.

Why the other choices are wrong
Each distractor category fails when the source records are compared: mismatches disagree on dose or frequency, duplicates represent the same active therapy twice, and stale entries describe completed therapy still marked active.References

## Clinical scenario

Reconciliation taxonomy
Compare the verified source with the active list, label the discrepancy, and route it for authorized resolution.
