Study Notes
Administration of Antibiotics
- Antibiotics must be administered correctly (accurate dosage, route, timing) to be effective and minimize side effects, following prescription and facility policies.
- Thorough patient education is crucial, explaining the medication's purpose, expected outcomes, potential side effects (nausea, vomiting, diarrhea), and necessary follow-up care. Patients must complete the full course, even if symptoms resolve.
- Closely monitor patients for allergic reactions (rash, hives, difficulty breathing) and other adverse effects (nausea, vomiting, diarrhea). Report and document any findings immediately.
Types of Antibiotics and Their Actions
- Penicillins: Target bacterial cell wall synthesis, preventing its formation. Examples: penicillin V, amoxicillin, methicillin. Penicillin allergies are common.
- Cephalosporins: Similar to penicillins, inhibiting bacterial cell wall synthesis. Different generations have varied activity spectra (gram-positive, gram-negative) and side effect profiles.
- Macrolides: Primarily inhibit protein synthesis. Examples: erythromycin, azithromycin, clarithromycin. Interactions with other medications are possible.
- Tetracyclines: Treat bacterial infections by inhibiting protein synthesis. Examples: doxycycline, tetracycline. Potential side effects, especially in pregnant women and children, are important to note.
- Aminoglycosides: Effective against a broad spectrum of bacteria, primarily targeting protein synthesis. Examples: gentamicin, tobramycin. High potential for ototoxicity (hearing damage) and nephrotoxicity (kidney damage). Monitor kidney and hearing functions.
- Quinolones: Target bacterial DNA replication, used to treat various infections. Examples: ciprofloxacin, levofloxacin. Potential side effects, including tendonitis and tendon rupture, require monitoring.
Nursing Considerations and Potential Complications
- Culture and Sensitivity: Obtain bacterial cultures and sensitivity tests before antibiotic therapy to guide appropriate antibiotic selection and ensure optimal treatment.
- Drug Interactions: Assess for concurrent medications and potential interactions with antibiotics.
- Patient Assessment: Conduct a comprehensive assessment of patients' baseline health, pre-existing conditions, and other medications to prevent drug-drug interactions.
- Monitoring Vital Signs: Monitor vital signs frequently, especially during the first few days of antibiotic therapy, as some patients may experience a fever during treatment.
- Blood Glucose: Antibiotics can affect blood sugar levels in some patients.
- Allergic Reactions: Manage severe allergic reactions (anaphylaxis) promptly.
- Gastrointestinal Issues: Educate patients about and treat common side effects like nausea, vomiting, and diarrhea.
- Superinfections: Monitor patients for superinfections (e.g., candidiasis) resulting from antibiotic disruption of normal flora.
- Organ Dysfunction: Monitor for kidney and liver impairment (especially with aminoglycosides and other specific antibiotics). Prevent nephrotoxicity and hepatotoxicity.
- Renal and Hepatic Function Testing: Frequent kidney and liver function tests may be needed for specific patients receiving antibiotic therapy.
Specific Considerations for Certain Patient Populations
- Older Adults: Older patients may be more susceptible to antibiotic side effects, specifically kidney issues. Adjust dosages as needed based on renal function.
- Pregnant and Breastfeeding Women: Prescribe antibiotics cautiously or avoid them due to potential fetal harm or transfer to breast milk; consultation may be needed.
- Children: Adjust antibiotic dosages based on a child's weight and maturity.
Patient Teaching Points
- Medication Compliance: Stress the importance of taking the full course of antibiotics, even if symptoms improve.
- Diet and Fluid Intake: Educate patients on dietary or fluid restrictions related to specific antibiotics.
- Side Effects Reporting: Teach patients to report any side effects to the healthcare provider.
- Hygiene and Prevention: Provide guidance on preventing infection transmission.
- Follow-up Care: Emphasize the importance of follow-up appointments and recommended lab tests.
- Food Interactions: Explain that certain antibiotics should be taken with food, while others should be taken on an empty stomach.
