Using aseptic technique is essential to reduce the risk of infection, and increased fluid intake is advised in amphotericin B therapy, but these would not help relieve the patient's symptoms or provide a measure of patient safety. Question 25 0 out of 1 points Which of the following nursing actions is most important in achieving successful antimicrobial therapy with vancomycin? Response Feedback : The goal of monitoring antibacterial therapy like vancomycin is to maintain the serum drug level within the therapeutic margin; this also ensures safety. Serum blood levels should be monitored for drugs that have a high potential for severe adverse effects. The other options can be broad goals of a general drug therapy that may or may not include an antibacterial drug. Antibiotic doses are not typically tapered down. Question 26 1 out of 1 points An immunocompromised patient in a critical care setting has developed a respiratory infection that has been attributed to methicillin- resistant Staphylococcus aureus (MRSA). The nurse should anticipate that

the patient will require treatment with Response Feedback: Vancomycin is the drug of choice to manage infections caused by MRSA. MRSA is resistant to all of the antistaphylococcic penicillins, as well as to ciprofloxacin and clindamycin. Question 27 1 out of 1 points A 30-year-old African-American woman tested positive for TB and is prescribed isoniazid. The nurse will plan the patient's care to include close monitoring of the drug therapy because Response Feedback : Isoniazid is metabolized in the body through a process called acetylation, which is faster in Eskimos, Asians, and approximately 50% of African Americans or European Americans from North America than in Scandinavians and people of Arab or Jewish heritage. Because the patient is an African American, she may exhibit slow acetylation for the drug, and as a result she may be at greater risk for serum levels and adverse effects. For this reason, the nurse would need to closely monitor this particular patient. Patients of African-American descent do not exhibit slow therapeutic effects of isoniazid or high rates of drug elimination. Question 28 1 out of 1 points A nurse has questioned why a patient's physician has prescribed a narrow- spectrum antibiotic rather than a broad-spectrum drug in the treatment of a patient's infection. Which of the following facts provides the best rationale for the use of narrow-spectrum antibiotics whenever possible? Response Feedback : The benefit of a narrow-spectrum antimicrobial agent is that it limits the potential for adverse effects, such as superinfection. In a superinfection, an antibiotic suppresses all susceptible microbes, including the body's natural flora, which may keep other microbes in check. In the absence of these bacteria, nonsusceptible microbes can proliferate. Narrow-spectrum antibiotics do not lack demonstrated efficacy and they do not necessarily require a shorter duration of treatment. All
