DHA Patient Care & Safety Standards 4

Question 1

A nurse discovers that a patient received a 10-fold overdose of insulin due to a look-alike/sound-alike (LASA) medication error. After stabilizing the patient, which action reflects the MOST appropriate application of the DHA's Just Culture framework?

Accepted Answer

File a mandatory incident report, conduct a root cause analysis focusing on system failures, and implement LASA alerts at the point of dispensing.

Answer

Just Culture distinguishes between human error and reckless behavior. A LASA error is a systemic vulnerability. DHA standards mandate immediate incident reporting, root cause analysis targeting system factors, and corrective controls at the point of care — not punitive blame of the individual nurse. Suspending staff without RCA perpetuates unsafe systems; delayed or selective reporting violates mandatory disclosure obligations.

Question 2

During a shift handover in a DHA-regulated facility, the oncoming nurse notices that the patient's National Early Warning Score (NEWS) has been trending upward over the past 4 hours but no escalation occurred. The current NEWS is 7. What is the MOST appropriate immediate action?

Accepted Answer

Initiate an urgent clinical review within 30 minutes and activate the facility's rapid response protocol.

Answer

A NEWS of 7 or above constitutes a high-risk threshold requiring urgent clinical review within 30 minutes and activation of the rapid response or early warning escalation protocol under DHA patient safety standards. Waiting, treating symptoms empirically, or deferring notification to a briefing all represent failures to escalate — a leading cause of preventable deterioration. The nurse must act independently of what the previous shift did or did not do.

Question 3

A patient scheduled for a right-sided nephrectomy has a wristband that reads 'John Smith' but verbally states his name as 'Jonathan Smith.' The surgical site marking on the consent form indicates 'left kidney.' Which combination of actions is REQUIRED before the procedure proceeds under DHA's Surgical Safety standards?

Accepted Answer

Proceed only after reconciling all three identifiers — full legal name, date of birth, and MRN — AND resolving the laterality discrepancy through re-consent and radiological confirmation.

Answer

DHA Surgical Safety standards (aligned with WHO Safe Surgery Checklist) require positive patient identification using at least two unique identifiers. Here, both the name identifier AND the surgical site on the consent form contain discrepancies. Both must be resolved before proceeding. Laterality errors are Never Events. The Time-Out alone is insufficient when upstream documentation conflicts exist; re-consent and radiological confirmation are required to correct the laterality discrepancy. Proceeding on imaging alone without corrected consent is legally and ethically impermissible.

Question 4

A healthcare worker in a DHA facility sustains a needlestick injury from a patient whose HIV status is unknown. The source patient refuses HIV testing. What is the CORRECT sequence of actions under DHA occupational exposure guidelines?

Accepted Answer

Administer post-exposure prophylaxis (PEP) within 72 hours, report to occupational health, pursue presumed-positive risk assessment, and document that source refused testing — do not force testing.

Answer

PEP must be initiated within 2 hours (and no later than 72 hours) of exposure; waiting for source consent forfeits this window. When source status is unknown and the patient refuses testing, DHA guidelines require treating the exposure as potentially high-risk, initiating PEP immediately, documenting the refusal, and conducting a presumed-positive risk assessment. Compelled testing of a competent refusing adult violates patient autonomy and UAE consent law. Deferring the PEP decision until specialist availability the next day is clinically dangerous.

Question 5

A nurse is preparing a high-alert medication infusion (concentrated potassium chloride) and is interrupted twice during preparation. She completes the infusion from memory and hangs it. Which patient safety principle was MOST critically violated, and what redundancy should have prevented this error?

Accepted Answer

The 'no-interruption zone' principle for high-alert medication preparation and mandatory independent double-check by a second licensed nurse before administration.

Answer

Concentrated potassium chloride is classified as a High-Alert Medication (HAM) by both ISMP and DHA standards due to its potential to cause death if administered incorrectly. DHA policy requires: (1) preparation in a designated no-interruption zone to prevent cognitive load errors, and (2) an independent double-check by a second qualified nurse verifying drug, dose, concentration, rate, and route before administration. The five rights checklist, pharmacist countersignature, and near-miss reporting are important but secondary — the no-interruption zone and independent double-check are the primary safety barriers that failed here.
