Question 19 0 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 Selected Answer: A. the production and maturation of CD4+ T-cells. Correct Answer: B. the permeability of fungal cell walls. 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, fungal reproduction, or the osmolarity within fungal cells.

Answer: C. Monitor serum drug level Correct Answer: A. Promote adequate intake of fluids and nutrients 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 21 1 out of 1 points Which of the following would a nurse assess for in a patient who is taking polymyxin B systemically? Selected Answer: D. Nephrotoxicity and hepatotoxicity Correct Answer: D. Nephrotoxicity and hepatotoxicity Response Feedback : The nurse would observe for the signs and symptoms of nephrotoxicity and hepatotoxicity. This drug is rarely administered systemically but has a potential for causing these serious adverse effects. Peripheral neuropathy, hyperkalemia, hyponatremia, endocarditis, and hypertension are not associated with the ingestion of polymyxin B.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
