Chapter 39 : Antibiotics Part 2 Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A 79-year-old patient is receiving a quinolone as treatment for a complicated incision infection. The nurse will monitor for which adverse effect that is associated with these drugs?
Correct Answer: D
Rationale: A black box warning is required by the U.S. Food and Drug Administration for all quinolones because of the increased risk for tendonitis and tendon rupture with use of the drugs. This effect is more common in elderly patients, patients with renal failure, and those receiving concurrent glucocorticoid therapy (e.g., prednisone). The other options are not common adverse effects.
Question 5 of 5
The nurse is administering intravenous vancomycin to a patient who has had gastrointestinal surgery. Which nursing measures are appropriate? (Select all that apply.)
Correct Answer: A,C,D,F
Rationale: Constant monitoring for drug-related neurotoxicity, nephrotoxicity, ototoxicity, and superinfection remains critical to patient safety. Monitor for nephrotoxicity by monitoring serum creatinine levels. Ototoxicity may be indicated if the patient experiences dizziness or a feeling of fullness in the ears, and these symptoms must be reported immediately. Vancomycin infusions may cause red man syndrome, which is characterized by flushing of the neck and face and a decrease in blood pressure. Optimal trough blood levels of vancomycin are 10 to 20 mcg/mL; therefore, the drug should not be administered when there is a trough level of 24 mcg/mL.
