Question 1 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. The patient's blood pressure, diet, weight, and other medications would be important to know and necessary for the plan of care, but are secondary to serum levels.  Question 2 1 out of 1 points The nurse notices a cold sore on a patient's upper lip and requests medication; docosanol (Abreva) is ordered. Before applying the medication, the nurse would first Response Feedback: The nurse would assess the area first to make sure that there were no open lesions or abrasions that could allow for systemic absorption of the drug. Then, the nurse would apply gloves and clean the area, pat dry, and apply the medication.  Question 3 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, fungal reproduction, or the osmolarity within fungal cells.  Question 4 1 out of 1 points A patient is taking rifampin (Rifadin) for active TB. When discussing this drug with the patient, the nurse should stress that Response Feedback: Rifampin can discolor body fluids red–orange. The patient should be informed that this is an expected adverse effect and is harmless. However, wearers of soft contact lenses should be cautioned that the lenses may be permanently discolored and that hard contacts or regular glasses should be used during the therapy. Although rifampin is often well tolerated, it may cause GI disturbances such as nausea and vomiting, anorexia, flatulence, cramps, and diarrhea. Cardiac arrhythmias, seizures, and facial flushing are not typically associated with the use of this drug.  Question 5 1 out of 1 points An immunocompromised patient in a critical care setting has developed a respiratory infection that has been attributed to methicillinresistant 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 6 1 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 7 1 out of 1 points A patient is receiving cefazolin in combination with anticoagulants. To minimize the adverse effects during therapy, the nurse will Response Feedback: The nurse should monitor for bleeding gums when the drug is administered in combination with anticoagulants, because patients who receive oral anticoagulants may experience increased bleeding. Administering the medication with small amounts of food and fluids
