Nursing Implications

Assessment: Monitor respiratory status, level of consciousness, signs of dependence.

Diagnoses:

  • Risk for addiction and dependence
  • Impaired sleep pattern

Implementation: Administer with food if gastrointestinal upset occurs; avoid alcohol and other CNS depressants.

Evaluation: Assess sleep quality, monitor for adverse effects, evaluate for signs of dependence.

Patient/Family Teaching

  • Do not operate machinery or drive until response is known.
  • Avoid alcohol and other sedatives.
  • Do not discontinue abruptly to prevent withdrawal symptoms.
  • Report any excessive sedation, respiratory depression, or changes in mood.

Special Considerations

Black Box Warnings:

  • Potential for addiction, abuse, and withdrawal symptoms.

Genetic Factors: Variability in metabolism may affect response.

Lab Test Interference: Potential interference with liver and kidney function tests.

Overdose Management

Signs/Symptoms: Profound sedation, respiratory depression, coma.

Treatment: Supportive care; airway management; activated charcoal if ingested recently; hemodialysis in severe cases.

🛡️ 5 Critical Medication Safety Tips for Nurses

1

Triple-Check High-Risk Medications

Always have another nurse verify insulin, heparin, warfarin, and chemotherapy drugs. These "high-alert" medications cause the most serious errors. Check concentration, dose calculation, and pump settings twice.

2

Know Look-Alike, Sound-Alike Drugs

Common mix-ups: hydromorphone/morphine, Celebrex/Celexa, Zyprexa/Zyrtec. Always use BOTH generic and brand names, read labels twice, and use barcode scanning when available. One wrong letter can be fatal.

3

Assess Before AND After Giving Meds

Check vitals before cardiac meds, pain levels before analgesics, and blood glucose before insulin. Always reassess within 30 minutes to evaluate effectiveness and watch for adverse reactions.

4

Watch for Drug Interactions

Common dangerous combinations: warfarin + aspirin (bleeding), ACE inhibitors + potassium (hyperkalemia), digoxin + diuretics (toxicity). Always check drug interactions before administering new medications.

5

Educate Your Patients

Teach patients medication names, purposes, major side effects, and what to report. Informed patients catch errors and improve compliance. Always encourage questions - an educated patient is a safer patient.

⚡ Remember: When in doubt, don't give it out! It's always safer to double-check than regret later.
