    Study Notes

    Pain Management

    • Acute vs chronic pain: understanding the distinction is crucial for effective pain management

    Opioid Drugs

    • Indications: moderate to severe pain management, cough suppression, and diarrhea treatment
    • Contraindications: respiratory depression, acute asthma, and hypersensitivity to opioids
    • Adverse Effects: respiratory depression, drowsiness, nausea, vomiting, and constipation
    • Management of overdose: naloxone administration and supportive care
    • Signs and Symptoms of opioid withdrawal: dysphoria, anxiety, insomnia, and muscle/bone pain

    Opioid Effects

    • Opioid Tolerance: decrease in response to opioid dosage over time
    • Physical Dependence: withdrawal symptoms upon cessation of opioid use
    • Psychologic Dependence: craving and compulsive opioid use

    Opioid Medications

    • Codeine Sulfate: often used for mild to moderate pain and cough suppression
    • Fentanyl: highly potent opioid, often used in anesthesia and breakthrough cancer pain
    • Hydromorphone (Dilaudid): potent opioid for severe pain management
    • Methadone Hydrochloride (Dolophine): used for opioid maintenance and withdrawal
    • Morphine Sulfate: potent opioid for severe pain management
    • Oxycodone Hydrochloride: often used for moderate to severe pain management
    • Naloxone Hydrochloride (Narcan): opioid antagonist used to reverse opioid overdose

    Nonopioid Analgesics

    • Indications: mild to moderate pain management, fever reduction, and anti-inflammatory effects
    • Dosage: varies depending on medication and condition being treated
    • Contraindications: hypersensitivity to nonopioid analgesics, severe liver damage, and bleeding disorders
    • Acetaminophen Overdose management: activated charcoal administration, N-acetylcysteine therapy, and supportive care

    Other Medications

    • Lidocaine: local anesthetic often used for pain management and arrhythmia treatment

    Nursing Process

    • Assessment: thorough patient evaluation to identify pain type, severity, and underlying causes
    • Nursing Implications: individualized patient care, opioid administration, and overdose management
