or provided as a constant infusion. Question 24 1 out of 1 points A patient is to begin taking tobramycin (Nebcin) for a nosocomial infection. Which of the following assessments should the nurse prioritize? Response Feedback: Peak and trough levels should be closely monitored with serious infections being treated with tobramycin.

secondary to serum levels. Question 25 1 out of 1 points A patient has been admitted to the critical care unit of the hospital with bacterial septicemia that has failed to respond to initial antibiotic treatment. The patient's most recent blood cultures reveal the presence of methicillin-resistant Staphylococcus aureus (MRSA) in the patient's blood. The nurse will anticipate that this patient will likely require intravenous administration of what antibiotic? Response Feedback: Vancomycin is used in treating bacterial septicemia, endocarditis, bone and joint infections, and pseudomembranous colitis caused by Clostridium difficile . Vancomycin is exceptionally effective for treating gram-positive infections in penicillin-allergic patients. It is also used for penicillin- and methicillin-resistant staphylococcal infections. Doripenem (Doribax) is used for abdominal or urinary tract infections and neither penicillin G nor cefazolin is effective in the treatment of MRSA infections. Question 26 1 out of 1 points Mr. Laird is a 49-year-old electrician who experienced severe burns on his trunk, arms, and hands in a workplace accident 2 weeks ago. Part of his current wound care regimen involves the daily application of silver sulfadiazine to his wounds. The nurses who are providing care for Mr. Laird in the burns and plastics unit of the hospital should perform what action when administering this medication? Response Feedback: Before applying silver sulfadiazine, it is necessary to cleanse the wound completely and remove dead or burned skin and other debris. It would be inappropriate to perform wound care after the application of the drug and it should be applied in a thin layer no more than about 1/16 inch. Application of topical sulfonamides is a sterile, not clean, procedure. Question 27 1 out of 1 points An immunocompromised patient with a diagnosis of candidiasis has failed to respond to conservative therapy and has consequently begun treatment with amphotericin B. The nurse is aware that this drug achieves a therapeutic effect by way of its influence on Response Feedback: Amphotericin B works by binding to sterols in fungal cell membranes. This binding appears to form pores or channels and results in increased cell permeability, cell leakage, and death. The drug does not influence human immune function,
