A client receiving morphine sulphate 4 mg IV reports that their pain hasn't improved at all after 30 minutes. What is the nurse's BEST action?

INADEQUATE PAIN CONTROL requires systematic reassessment before any intervention. The nurse cannot simply give more opioid without assessment.

Comprehensive reassessment:

Pain assessment: Use a validated scale (NRS 0-10, Wong-Baker FACES, FLACC for non-verbal); Ask about location, quality (sharp, burning, aching, throbbing), intensity, radiation, duration, aggravating/relieving factors; Was the pain score accurate before the dose? Has it changed at all?

Vital signs: Before administering more opioid, check respiratory rate, oxygen saturation, BP, HR; if respiratory rate below 12 or SpO₂ decreasing, do NOT give more opioid — call provider.

Review the order: What is the frequency? What is the dosage range (e.g., 2-4 mg)? When was the last dose? What are the parameters for holding or calling?

Possible causes of inadequate relief: Under-dosing for the pain level; wrong route for the situation; inadequate drug for pain type (opioids work poorly for neuropathic pain — may need adjuvants).

Contact provider: If pain remains uncontrolled after the assessment and another dose is clinically safe and ordered, notify provider with SBAR report: current pain score, vital signs, what was given, what the response has been, and request additional order. ADEQUATE PAIN CONTROL IS A PATIENT RIGHT — inadequate pain management should be escalated, not accepted as normal.
