Aspirin, or acetylsalicylic acid, is a widely used nonsteroidal anti-inflammatory drug (NSAID) valued for its pain-relieving, anti-inflammatory, and antiplatelet properties. Nurses play a vital role in ensuring its safe and effective use by assessing patients, administering the drug correctly, monitoring for side effects, and providing education. This article outlines key nursing considerations and management strategies for aspirin therapy.

What is Aspirin and How Does It Work?
Aspirin inhibits the enzyme cyclooxygenase (COX), reducing prostaglandin production, which alleviates pain, inflammation, and fever. Its antiplatelet effect prevents blood clot formation, making it essential for cardiovascular protection.
Key Uses:
- Pain relief (e.g., headaches, arthritis)
- Inflammation reduction
- Fever reduction
- Clot prevention (e.g., post-heart attack or stroke)
Nursing Assessment: Pre-Administration
A thorough assessment identifies risks and ensures patient safety.
1. Patient History
- Allergies: Confirm no hypersensitivity to aspirin or other NSAIDs (e.g., rash, anaphylaxis risk).
- Medical Conditions: Screen for contraindications:
- Bleeding disorders (e.g., hemophilia)
- Active or past gastrointestinal ulcers
- Severe liver/kidney disease
- Asthma (risk of aspirin-exacerbated respiratory disease)
2. Medication Review
- Check for drugs that interact with aspirin:
- Anticoagulants (e.g., warfarin)
- Other NSAIDs (e.g., ibuprofen)
- Corticosteroids
3. Baseline Data
- Record vital signs (e.g., blood pressure).
- Assess labs (e.g., platelet count) for antiplatelet therapy patients.
Pre-Administration Checklist:
- No aspirin/NSAID allergies
- No contraindicating conditions
- Medication interactions reviewed
Planning Aspirin Therapy
Planning ensures proper dosing and patient-specific care.
1. Dosage
- Pain/Inflammation: 325-650 mg every 4-6 hours as needed.
- Antiplatelet: 81 mg daily for clot prevention.
- Adjust for renal impairment or elderly patients.
2. Timing
- Administer with food or milk to reduce gastric irritation.
- Use enteric-coated aspirin for sensitive stomachs.
3. Special Populations
- Elderly: Lower doses; monitor for bleeding.
- Pregnant Women: Avoid in third trimester; low-dose may be used for preeclampsia (per physician).
- Children: Avoid due to Reye’s syndrome risk.
Implementation: Administering Aspirin
Correct administration enhances efficacy and safety.
1. Methods
- Oral: Swallow tablets with water; use chewable/liquid forms if needed.
- Emergency (e.g., myocardial infarction): Chew 325 mg immediately.
2. Patient Education
- Take as prescribed, with food if possible.
- Avoid alcohol to prevent gastric bleeding.
- Report bleeding (e.g., black stools) or stomach pain.
Example Instruction:
“Take your 81 mg aspirin with breakfast to protect your heart. Call us if you notice bruising or dark stools.”
Monitoring and Evaluation
Ongoing monitoring ensures effectiveness and early detection of issues.
1. Side Effects
- Bleeding: Look for bruising, nosebleeds, or bloody stools.
- GI Distress: Note stomach pain or heartburn.
- Toxicity: Tinnitus signals high doses.
2. Effectiveness
- Assess pain relief or symptom improvement.
- Monitor for clot-related events in antiplatelet therapy.
3. Labs
- Check coagulation profiles for long-term use.
- Monitor renal/liver function as needed.
Managing Complications
Prompt action minimizes harm from adverse effects.
1. Bleeding
- Stop aspirin; notify provider; provide supportive care.
2. GI Issues
- Use food or enteric-coated aspirin; consider PPIs if persistent.
3. Allergic Reactions
- Discontinue aspirin; treat with antihistamines/epinephrine per orders.
Drug Interactions
Aspirin interacts with:
- Anticoagulants: Increased bleeding risk.
- NSAIDs: Reduced antiplatelet effect, higher GI risk.
- Herbal Supplements (e.g., ginkgo): Enhanced bleeding risk.
Action: Regularly review medications and educate patients.
Patient Education
Empower patients with clear guidance:
- Follow dosing instructions.
- Watch for bleeding or GI symptoms.
- Avoid alcohol.
- Inform providers about aspirin use before procedures.
Documentation
Record:
- Dose, time, and route.
- Side effects observed/reported.
- Education provided and patient response.
Example Entry:
“Administered aspirin 325 mg at 0900 for pain. Patient advised to take with food due to mild nausea.”
Conclusion
Aspirin’s versatility requires careful nursing oversight. Through diligent assessment, administration, monitoring, and education, nurses ensure its benefits outweigh its risks, optimizing patient outcomes.
