Understanding the Basics of Nursing Pharmacology
Before delving into specific drug classes, it’s crucial to understand foundational pharmacology concepts that underpin safe medication administration.
Core Principles of Pharmacology
- Pharmacokinetics: How the body absorbs, distributes, metabolizes, and excretes drugs.
- Pharmacodynamics: How drugs affect the body, including mechanisms of action and therapeutic effects.
- Drug Dosage and Administration: Proper measurement, timing, and route of medication delivery.
- Side Effects and Adverse Reactions: Recognizing common and severe responses to medications.
- Patient Safety: Identifying allergies, contraindications, and interactions.
Common Routes of Administration
- Oral (PO)
- Intravenous (IV)
- Intramuscular (IM)
- Subcutaneous (SubQ)
- Topical
- Inhalation
- Rectal or Vaginal
Key Nursing Responsibilities in Pharmacology
- Verify medication orders for accuracy.
- Check patient allergies.
- Calculate correct dosages.
- Administer medications safely.
- Monitor for therapeutic and adverse effects.
- Educate patients about their medications.
Major Drug Classes in Nursing Pharmacology
Understanding the key drug classes helps nurses anticipate effects, side effects, and patient education points.
1. Analgesics
- Opioids (e.g., Morphine, Hydrocodone)
- Use: Severe pain relief
- Side Effects: Respiratory depression, constipation, sedation
- Nursing Considerations: Monitor respiratory status, assess pain level, consider bowel regimen
- Non-opioid analgesics (e.g., Acetaminophen, NSAIDs)
- Use: Mild to moderate pain
- Side Effects: Liver toxicity (acetaminophen), GI bleeding (NSAIDs)
- Nursing Considerations: Watch for overdose, monitor for GI symptoms
2. Antibiotics
- Penicillins (e.g., Amoxicillin)
- Cephalosporins (e.g., Ceftriaxone)
- Macrolides (e.g., Azithromycin)
- Tetracyclines (e.g., Doxycycline)
- Fluoroquinolones (e.g., Ciprofloxacin)
- Use: Bacterial infections
- Side Effects: Allergic reactions, GI upset, antibiotic resistance
- Nursing Considerations: Complete full course, monitor for allergic reactions, educate about photosensitivity
3. Cardiovascular Drugs
- ACE Inhibitors (e.g., Lisinopril)
- Use: Hypertension, heart failure
- Side Effects: Cough, hyperkalemia, hypotension
- Beta-Blockers (e.g., Metoprolol)
- Use: Hypertension, angina
- Side Effects: Bradycardia, fatigue
- Diuretics (e.g., Furosemide)
- Use: Edema, hypertension
- Side Effects: Electrolyte imbalances, dehydration
4. Central Nervous System (CNS) Drugs
- Antianxiety agents (e.g., Benzodiazepines)
- Antidepressants (e.g., SSRIs such as Fluoxetine)
- Antipsychotics (e.g., Haloperidol)
- Antiepileptics (e.g., Phenytoin)
- Use: Anxiety, depression, psychosis, seizures
- Nursing Considerations: Monitor mental status, check for signs of toxicity, avoid abrupt discontinuation
5. Respiratory Medications
- Bronchodilators (e.g., Albuterol)
- Corticosteroids (e.g., Fluticasone)
- Anticholinergics (e.g., Ipratropium)
- Use: Asthma, COPD
- Nursing Considerations: Educate on inhaler technique, monitor for tremors and tachycardia
6. Endocrine Drugs
- Insulin (e.g., Regular, NPH)
- Use: Diabetes mellitus
- Nursing Considerations: Monitor blood glucose, rotate injection sites
- Oral hypoglycemics (e.g., Metformin)
- Use: Type 2 diabetes
- Nursing Considerations: Monitor renal function, educate about diet and exercise
Important Pharmacology Concepts for Nurses
To optimize medication safety, nurses must understand several critical pharmacology concepts.
Drug Interactions
- Synergistic effects: When drugs enhance each other's effects.
- Antagonistic effects: When drugs inhibit each other.
- Examples:
- Combining NSAIDs with anticoagulants increases bleeding risk.
- Taking antihypertensives with alcohol may cause hypotension.
Therapeutic Window and Monitoring
- The range between effective and toxic drug levels.
- Regular blood tests may be necessary for drugs like warfarin, digoxin, and phenytoin.
Patient Education and Safety Tips
- Always verify the correct medication, dose, route, and time.
- Educate patients about potential side effects and when to seek help.
- Encourage adherence to prescribed regimens.
- Emphasize the importance of keeping a medication list.
Common Nursing Pharmacology Quick Reference List
To assist nurses during clinical practice, here is a quick reference of common medications and key points:
- Acetaminophen: Use for mild pain and fever. Watch for overdose leading to liver damage.
- Furosemide: Loop diuretic for edema. Monitor electrolytes and hydration status.
- Lisinopril: ACE inhibitor for hypertension. Monitor blood pressure and potassium levels.
- Albuterol inhaler: Fast-acting bronchodilator. Use as needed for asthma attacks.
- Insulin: Regulate blood glucose in diabetics. Rotate injection sites to prevent lipodystrophy.
- Warfarin: Anticoagulant. Monitor INR levels and educate about bleeding precautions.
- Metoprolol: Beta-blocker for hypertension and angina. Watch for bradycardia and hypotension.
- Fluoxetine: SSRI for depression. Watch for serotonin syndrome and suicidal thoughts.
