Study Notes
Nonopioid Analgesics
- Common nonopioid analgesics include aspirin, naproxen, ibuprofen, and acetaminophen.
- Acetaminophen effectively reduces fever by inhibiting the hypothalamic heat-regulator center.
Opioid Analgesics
- Morphine and codeine are derived from the poppy plant and are classified as opioids.
- The fastest onset of morphine occurs via intravenous administration.
Acetaminophen Risks and Considerations
- Overdosing on acetaminophen can lead to hepatotoxicity, a serious liver condition.
- Maximum recommended dosage for adults is 4 grams per day.
- Patients taking acetaminophen should avoid alcohol to minimize liver strain.
- Assess a patient's history of liver dysfunction before administering acetaminophen.
Side Effects of Morphine
- Common side effects of oral morphine include dizziness, constipation, and respiratory depression.
- Patients taking morphine should report symptoms like dizziness, headaches, blurred vision, and difficulty breathing.
Administration Routes and Conditions
- In patients unable to take oral medications, consider administering acetaminophen rectally, but be aware absorption may be affected by constipation.
- Acetaminophen is effective for treating fever, headaches, and mild to moderate pain.
Pharmacologic Properties
- Acetaminophen is a nonopioid medication but does not fall under the NSAID category.
- Due to its short half-life, acetaminophen can be administered every 4 hours as needed for pain relief.
Opioid Mechanism of Action
- Opioids mainly activate mu receptors, leading to sedation, euphoria, and analgesia.
- Activation of mu receptors may cause respiratory depression as a side effect.
Patient Care and Monitoring
- For patients in severe pain without swallowing capability, rectal morphine administration is advisable.
- Important pharmacokinetic factor for oral morphine is that it undergoes first hepatic pass metabolism.
- Nurses should inquire about alcohol consumption and liver disease history when assessing patients on acetaminophen.
Emergency and Postoperative Considerations
- Before administering acetaminophen in an emergency setting, confirm if the patient has taken any earlier in the day.
- Patients on frequent morphine should have liver function tests monitored.
- Continuous infusion of morphine requires monitoring of urinary output, respiratory rate, and bowel sounds.
Patient Assessment and Interventions
- Elevated liver tests and a serum acetaminophen level of 10 suggest acetaminophen is likely not contributing to liver issues.
- Encourage nonpharmacologic pain relief options for patients recovering from surgery wishing to avoid opioids.
- In cases of potential acetaminophen overdose in children, immediate emergency department referral is necessary.
