Medication Reconciliation And Safety - NCLEX Pn

1. Which abbreviation should be avoided because it can be misread as "0" or "4"?

   Avoid "U" for units; write "units". "U" is error-prone as it resembles numerals, potentially causing tenfold dosing mistakes like confusing 10U with 100.

2. What is the correct trailing-zero practice to prevent tenfold dosing errors?

   Do not use trailing zeros (write $1$ mg, not $1.0$ mg). Trailing zeros can obscure decimals, causing errors like reading 1.0 mg as 10 mg.

3. Identify the discrepancy type: the inpatient order duplicates a home medication with the same therapeutic effect.

   Therapeutic duplication. Duplication increases risk of overdose or adverse effects by ordering equivalent therapies redundantly.

4. Which action is required when a barcode scan alerts "wrong medication" at the bedside?

   Stop and verify medication, order, and patient before proceeding. Alerts indicate potential mismatches, requiring verification to ensure the right medication reaches the correct patient.

5. What is the safest nursing action when a medication allergy is listed but the reaction is undocumented?

   Clarify the reaction history before administration. Undocumented reactions may indicate true allergies or intolerances, requiring clarification to avoid potentially life-threatening administration.

6. What is the correct leading-zero practice for doses less than $1$ to prevent decimal errors?

   Use a leading zero (example: $0.5$ mg), never $.5$ mg. Leading zeros prevent misreading decimals, such as interpreting .5 mg as 5 mg, avoiding overdose.

7. Which patient sources must be used first to obtain the Best Possible Medication History (BPMH)?

   Patient or caregiver interview plus medication bottles or an up-to-date list. Primary sources provide the most reliable, patient-specific information for an accurate BPMH, reducing reliance on secondary data.

8. What key elements must be documented for each medication during reconciliation?

   Name, dose, route, frequency, indication, and last dose time. These elements ensure comprehensive documentation to prevent errors in prescribing, dispensing, and administering medications.

9. Identify the required documentation after administering a PRN analgesic for pain rated $8$ out of $10$.

   Document dose given and reassess and document response within ordered timeframe. Documentation captures administration details and evaluates effectiveness, ensuring accountability and guiding further care.

10. Which statement best defines a "look-alike/sound-alike" (LASA) medication risk?

    Different drugs with similar names or packaging increase selection errors. LASA medications pose risks due to confusion in selection, leading to wrong-drug errors in storage or dispensing.

11. Which action is required before administering any medication when two patient identifiers do not match?

    Do not administer; resolve the identification discrepancy first. Mismatched identifiers risk wrong-patient errors, so resolution ensures positive identification before proceeding.

12. Which medication category is commonly missed in reconciliation and must be asked about explicitly?

    Over-the-counter drugs, herbals, and supplements. These non-prescription items can interact with prescribed drugs, leading to omissions if not specifically queried.

13. What is the primary purpose of medication reconciliation during transitions of care?

    Prevent medication errors by ensuring an accurate, complete medication list. Medication reconciliation identifies and resolves discrepancies to maintain continuity and avoid adverse events during care changes.

14. Which high-alert medication class requires independent double-checks per facility policy?

    Insulin (high-alert medication). High-alert medications like insulin have narrow therapeutic indices, necessitating double-checks to prevent severe harm from errors.

15. What does the "rights of medication administration" concept primarily ensure?

    Correct patient, medication, dose, route, time, documentation, reason, response. These rights provide a systematic checklist to verify accuracy and appropriateness, minimizing administration errors.

16. Which abbreviation should be avoided because it can be misread as "daily"?

    Avoid "QOD"; write "every other day". "QOD" may be confused with "QD," leading to incorrect daily dosing instead of alternate days.

17. Which three points in care most require medication reconciliation to reduce errors?

    Admission, transfer, and discharge. These transition points are high-risk for discrepancies due to changes in providers, settings, or patient status.

18. What is the single most important action when a home medication order is unclear or incomplete?

    Hold the dose and clarify the order with the prescriber or pharmacist. Clarification prevents potential harm from incorrect administration, prioritizing patient safety over assumption.

19. Identify the safest action when a patient states a home medication was stopped, but it remains on the record.

    Verify with prescriber or pharmacy and update the active medication list. Verification confirms accuracy of the record, preventing unnecessary continuation or errors in ongoing care.

20. Which instruction best reduces LASA errors when documenting or transcribing medication names?

    Use Tall Man lettering and avoid ambiguous abbreviations. Tall Man lettering highlights differences in similar names, while avoiding abbreviations reduces misinterpretation in orders.

21. Identify the discrepancy type: a patient home medication is not ordered on admission with no reason documented.

    Omission. Omission occurs when a necessary medication is unintentionally excluded from the inpatient regimen without justification.

22. Which teaching point is essential when discharging a patient with a new medication list?

    Explain which meds to start, stop, continue, and why, using a written list. Clear instructions promote adherence and understanding, reducing post-discharge errors through education and documentation.

23. Identify the discrepancy type: the ordered dose differs from the home dose without clinical justification.

    Dose discrepancy. Unjustified dose changes can lead to subtherapeutic effects or toxicity, requiring reconciliation to align with patient needs.

24. What is the correct immediate action if a patient experiences suspected anaphylaxis after a medication dose?

    Stop the medication and initiate emergency response per protocol. Immediate cessation and protocol activation address life-threatening reactions to minimize harm and stabilize the patient.

25. Which action best prevents contamination when preparing and administering injectable medications?

    Use aseptic technique and scrub the vial or port per policy. Aseptic technique and scrubbing maintain sterility, reducing infection risk during preparation and injection.
