Common agents include: Penicillin Cephalosporin Aminoglycoside (Gentamicin, Neomycin, Tobramycin) Sulfonamide (Bactrim, Septra, Gantrisin) Tetracycline Monobactam Macrolide (Erythromycin, Azithromycin) Fluoroquinolones (Ciprofloxacin, Levofloxacin) The effectiveness of an antibiotic can be altered by the manner in which it is taken. Antibiotics should be taken at regular intervals to maintain appropriate concentrations. Some antibiotics must be taken on an empty stomach while others specifically must be taken with a meal. Most should be taken with a full glass of water, and some should not be taken with dairy products or close to the time dairy products are consumed. It is good practice to culture the suspected bacteria first. This will allow for a definitive treatment with an antibiotic that the organism is susceptible to. However, if treatment is required sooner, guidelines for the specific medication should be adhered to. It is also important to assess the severity of the illness. This will be a factor in how aggressively to treat and how long to treat. Allergic reactions can occur even in patients who have not previously shown sensitivity to the medication. It is important to observe the patient closely while the medication is being administered. Reactions may be rapid in onset or may not occur for days or weeks following the initiation of the therapy. Allergic reactions vary in intensity from a mild rash to anaphylaxis An important complication is that of a superinfection. These superinfections occur due to the resistance of a second microbe to the antibiotic. For example, women may get a vaginal yeast infection from an antibiotic treatment. Adverse effects are different from allergic reactions. They are often considered expected side effects of the medications. Common adverse effects are nausea, vomiting and diarrhea. Serious adverse reactions include bone marrow suppression. Some antibiotics have very specific and severe adverse effects and contraindications. Nursing Consideration and Patient Education: Antibiotics may interfere with oral contraceptives. The patient should take the medication exactly as ordered since the timing of some antibiotics is crucial to maintain therapeutic levels. Do not stop the medication even if the patient feels better. The organism may not have been completely destroyed. Patients should be instructed to contact their physician if the symptoms worsen or do not improve. Superinfections caused by the overgrowth of nonsusceptible organisms, like yeast, may occur with antibiotic use. Symptoms may be diarrhea, anogenital itching, vaginal discharge or stomatitis< Encourage the patient to increase fluid intake, especially water, if it is not contraindicated.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
