    Study Notes

    Infections

    • Community-associated infections vs Health care–associated infections are two types of infections with different prevention strategies.

    Antibiotic Therapy

    • Superinfection is a potential complication of antibiotic therapy.
    • Allergic reactions to antibiotics can occur, with severe reactions including anaphylaxis, Stevens-Johnson syndrome, and toxic epidermal necrolysis.

    Sulfonamides

    • Sulfonamides are bacteriostatic antibiotics used to treat pneumonia, meningitis, and urinary tract infections.
    • Adverse effects of sulfonamides include allergic reactions, crystalluria, and kernicterus.

    Beta-Lactam Antibiotics

    • Natural penicillin’s:
      • Penicillin G is effective against gram-positive bacteria and used to treat pneumonia, meningitis, and sepsis.
      • Penicillin V is used to treat strep throat and skin infections.
    • Penicillinase-resistant drugs:
      • Nafcillin, Cloxacillin, Oxacillin, and Dicloxacillin are used to treat methicillin-resistant Staphylococcus aureus (MRSA) infections.
    • Aminopenicillins:
      • Amoxicillin and Ampicillin are used to treat infections of the respiratory tract, urinary tract, and skin.
    • Extended-spectrum drugs:
      • Carbenicillin, Piperacillin, and Ticarcillin are used to treat infections caused by Pseudomonas aeruginosa and other gram-negative bacteria.

    Penicillin’s

    • Contraindications include allergy to penicillin, lactation, and certain infections.
    • Adverse effects include allergic reactions, diarrhea, and nausea.
    • Interactions include probenecid, aspirin, and warfarin.
    • Patient education topics include allergic reactions, dosage, and medication administration.

    Cephalosporins

    • Cephalosporins can be grouped by generation (1st, 2nd, 3rd, 4th, and 5th).
    • Patient education regarding interactions with warfarin, aminoglycosides, and probenecid.

    Carbapenems

    • Imipenem/cilastatin (Primaxin), Meropenem (Merrem), Ertapenem (Invanz), and Doripenem (Doribax) are used to treat infections caused by gram-positive and gram-negative bacteria.
    • Indications include pneumonia, meningitis, and sepsis.

    Macrolides

    • Erythromycin (E-mycin, E.E.S, others), Azithromycin (Zithromax), and Clarithromycin (Biaxin) are used to treat infections of the respiratory tract, skin, and soft tissue.
    • Fidaxomicin (Dificid) is used to treat Clostridioides difficile infections.
    • Indications include pneumonia, bronchitis, and sinusitis.
    • Interactions include warfarin, theophylline, and digoxin.
    • Adverse effects include nausea, vomiting, and diarrhea.

    Tetracyclines

    • Demeclocycline (Declomycin), Oxytetracycline (Terramycin), Tetracycline, Doxycycline (Doryx, Vibramycin), and Minocycline (Minocin) are used to treat infections of the respiratory tract, skin, and urinary tract.

    • Patient education topics include allergic reactions, photosensitivity, and medication administration.
    • Interactions include antacids, warfarin, and diuretics.
    • Adverse effects include nausea, vomiting, and diarrhea.

    Aminoglycosides

    • Gentamicin, Neomycin (Neo-Fradin), Tobramycin (TOBI), and Amikacin are used to treat infections of the respiratory tract, skin, and urinary tract.
    • Adverse effects include ototoxicity, nephrotoxicity, and neuromuscular blockade.

    Quinolones

    • Ciprofloxacin (Cipro), Norfloxacin (Noroxin), Levofloxacin (Levaquin), Moxifloxacin (Avelox), Gemifloxacin (Factive), and Delafloxacin (Baxdela) are used to treat infections of the urinary tract, respiratory tract, and skin.
    • Indications include pneumonia, bronchitis, and sinusitis.
    • Interactions include warfarin, theophylline, and antacids.
    • Adverse effects include tendon rupture and QT prolongation.

    Miscellaneous Antibiotics

    • Metronidazole (Flagyl) is used to treat infections of the gastrointestinal tract, genitourinary tract, and skin.
    • Nitrofurantoin (Macrodantin) is used to treat urinary tract infections.
    • Vancomycin is used to treat infections of the respiratory tract, skin, and urinary tract.
    • Indications include MRSA infections and Clostridioides difficile infections.

    Nursing Implications

    • All antibiotics require patient education on allergic reactions, dosage, and medication administration.
    • Nurses should monitor patients for adverse effects, interactions, and contraindications.
    • Appropriate antibiotic selection and administration are critical to effective treatment and prevention of antibiotic resistance.
