## Question

A client reports a single acute acetaminophen overdose exactly 2 hours ago. Place the actions in the safest sequence.

At 4 hours after ingestion, obtain the acetaminophen concentration and ordered liver, renal, glucose, electrolyte, and coagulation tests.

Begin the authorized acetylcysteine regimen promptly if the result is above the treatment line or if timely interpretation becomes unavailable.

Continue the prescribed regimen and serially reassess acetaminophen concentration, liver and renal function, coagulation, glucose, electrolytes, and clinical status.

Plot the timed concentration on the revised Rumack-Matthew nomogram when it is valid for this acute ingestion.

Stabilize airway, breathing, and circulation; verify the ingestion time and contact the poison-management resource.

## Explanation

The sequence stabilizes the client, obtains a valid timed level, interprets the acute ingestion correctly, starts antidote without harmful delay, and follows organ response.

## In-depth explanation

Quick answer
Sequence stabilize, time, plot, antidote, trend.

Why this is correct
A concentration obtained before 4 hours may be misleading. When timing is unknown, results are delayed beyond the protective window, or toxicity is evident, acetylcysteine should not be delayed for a nomogram result.

Easy analogy or mental picture
Treat medication safety like airway triage: identify the threat, interrupt exposure, support physiology, and verify a durable response.

Memory hook
Cue, risk, action, response, recurrence check.

NCLEX decision rule
Choose the action that prevents the most immediate medication-related harm while preserving reassessment and escalation.

Why the other choices are wrong
Options that normalize deterioration, add interacting medication, or delay rescue leave the safety loop open.References

## Clinical scenario

Medication safety review
Verify the indication, current assessment, respiratory and neurologic status, interactions, authorized rescue action, and measurable follow-up.
