Chapter 39 : Antibiotics Part 2 Questions
Question 1 of 5
A patient who has been hospitalized for 2 weeks has developed a pressure ulcer that contains multidrug-resistant Staphylococcus aureus (MRSA). Which drug would the nurse expect to be chosen for therapy?
Correct Answer: C
Rationale: Vancomycin is the antibiotic of choice for the treatment of MRSA. The other drugs are not used for MRSA.
Question 2 of 5
A patient is receiving aminoglycoside therapy and will be receiving a beta-lactam antibiotic as well. The patient asks why two antibiotics have been ordered. What is the nurse's best response?
Correct Answer: A
Rationale: Aminoglycosides are often used in combination with other antibiotics, such as beta-lactams or vancomycin, in the treatment of various infections because the combined effect of the two antibiotics is greater than that of either drug alone.
Question 3 of 5
The nurse is reviewing the medication orders for a patient who will be receiving aminoglycoside therapy. Which other medication or medication class, if ordered, would be a potential interaction concern?
Correct Answer: D
Rationale: Concurrent use of aminoglycosides with loop diuretics increases the risk for ototoxicity. The other drugs and drug classes do not cause interactions.
Question 4 of 5
The nurse checks the patient's laboratory work prior to administering a dose of vancomycin and finds that the trough vancomycin level is 15 mcg/mL. What will the nurse do next?
Correct Answer: A
Rationale: Optimal blood levels of vancomycin are a trough level of 10 to 20 mcg/mL. Measurement of peak levels is no longer routinely recommended, and only trough levels are commonly monitored. Because of the increase in resistant organisms, many clinicians use a trough level of 15 to 20 mcg/mL as their goal.
Question 5 of 5
A patient has been diagnosed with carbapenem-resistant Enterobacteriaceae (CRE). The nurse expects to see orders for which drug?
Correct Answer: D
Rationale: Colistimethate sodium (Coly-Mycin), commonly referred to as colistin, is now being used again, often as one of the only drugs available to treat CRE. The other options are incorrect.
