A nurse is part of an interprofessional team conducting a root cause analysis (RCA) after a sentinel event involving a medication error that caused serious patient harm. Which nursing action best supports the RCA process to prevent future similar events?

Rationale:
A. Scanning the bar code on the medication administration record (MAR) and the client’s armband is correct practice. This is part of barcode-assisted medication administration (BCMA), which helps ensure the “five rights” of medication administration: right patient, right drug, right dose, right route, and right time.

B. Documenting medication administration prior to giving the medication is incorrect and requires intervention because it can lead to medication errors and falsification of records. Accurate documentation should always occur after the medication is administered to ensure the record reflects what was actually given and to maintain patient safety. Pre-documentation creates a risk of missing errors, skipped doses, or giving the wrong medication.

C. Checking the provider's orders and confirming the dosage in a medication reference guide is correct because it demonstrates due diligence in verifying medication safety and dosage accuracy before administration.

D. Verifying the medication against the prescription and medication label is correct as it ensures accuracy in medication delivery, preventing errors such as administering the wrong drug or incorrect dose.

Rationale:

A. "Provide discharge instructions to a confused client's spouse" is incorrect because teaching requires assessment of learning needs and comprehension, which is within the scope of the registered nurse (RN), not the LPN. Providing discharge teaching involves critical thinking and evaluation, so it cannot be delegated.

B. "Initiate a plan of care for a client who is postoperative from an appendectomy" is incorrect because developing and initiating the plan of care requires assessment, nursing judgment, and care prioritization, which are responsibilities of the RN. LPNs can implement portions of the plan, but not initiate it independently.

C. "Obtain vital signs from a client who is 6 hr postoperative" is correct because obtaining vital signs is a routine, non-invasive task within the LPN’s scope. The LPN can collect the data, while the RN remains responsible for interpreting results and determining interventions.

D. "Catheterize a client who has not voided in 8 hr" is correct because urinary catheterization is a skill within the LPN’s scope in most states or facilities. The LPN can perform the procedure safely and report output and patient response to the RN.

E. "Administer a tap-water enema to a client who is preoperative" is correct because administering enemas is a common LPN task. It is a procedural intervention that does not require complex assessment or independent nursing judgment beyond following protocol.
