This 4-page NR 566 Week 1 Exam study guide contains 19 questions with answers covering advanced pharmacotherapeutics, antifungal medications, antiviral therapy, antiretroviral drugs, medication mechanisms of action, adverse effects, and clinical treatment decisions. Major topics include echinocandins such as caspofungin, amphotericin B nephrotoxicity, terbinafine, itraconazole hepatotoxicity and cardiac risks, fluconazole, nystatin, and griseofulvin. The document also examines acyclovir, intravenous antiviral administration, renal dosage adjustments, oseltamivir for influenza treatment during pregnancy, Paxlovid for COVID-19, and antiviral management of herpes simplex and varicella-zoster infections. Additional questions address HIV antiretroviral therapy, efavirenz, adverse drug reactions, mebendazole's mechanism of action, oral thrush, onychomycosis, tinea capitis, vulvovaginal candidiasis, and medication selection in immunocompromised patients. Clinical scenarios emphasize pharmacological safety, contraindications, drug toxicity, patient-specific treatment considerations, and prescribing decisions. Relevant supplementary academic references include Rosenthal and Burchum's Lehne's Pharmacotherapeutics for Advanced Practice Nurses and Physician Assistants and Katzung's Basic & Clinical Pharmacology. These textbooks support the subject matter but are not verified as sources cited in the uploaded document. This resource is suitable for Chamberlain University students, Family Nurse Practitioner (FNP) students, Master of Science in Nursing (MSN) students, Doctor of Nursing Practice (DNP) students, Advanced Practice Registered Nurse (APRN) students, and graduate nursing students preparing for advanced pharmacology examinations.
