After teaching a group of nursing students about indications for linezolid (Zyvox), the instructor determines a need for additional teaching when the students identify which of the following as an indication?
- A. Community-acquired pneumonia (CAP)
- B. Vancomycin-resistant Enterococcus faecium (VREF)
- C. Methicillin-resistant Staphylococcus aureus (MRSA)
- D. Acute otitis media
Correct Answer: D
Rationale: Linezolid is used in the treatment of vancomycin-resistant Enterococcus faecium (VREF), health care? and community-acquired pneumonias, and skin and skin structure infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA). It is not used to treat otitis media.

A client is receiving gentamicin. Assessment of which of the following would lead the nurse to suspect that the client is developing nephrotoxicity? Select all that apply.
- A. Proteinuria
- B. Hematuria
- C. Decreased urine output
- D. Increased serum creatinine
Correct Answer: A, B, C, D
Rationale: Proteinuria, hematuria, decreased urine output, increased serum creatinine, and increased blood nitrogen urea (BUN) are suggestive of nephrotoxicity. Decreased fluid intake would support dehydration.
A group of nursing students are reviewing information about aminoglycosides. The students demonstrate understanding when they identify which of the following as an example? Select all that apply.
- A. Amikacin (Amikin)
- B. Amoxicillin (Amoxil)
- C. Kanamycin (Kantrex)
- D. None of the above
Correct Answer: A
Rationale: The aminoglycosides include amikacin, gentamicin, kanamycin, neomycin, streptomycin, and tobramycin. Amoxicillin is an aminopenicillin. Vancomycin is a miscellaneous agent that disrupts the bacterial cell wall. Azithromycin is classified as a macrolide.
A nurse is reviewing the medical record of a client who is prescribed tetracycline. The nurse would be alert for an increased risk of toxicity if the client is taking which of the following? Select all that apply.
- A. Digoxin (Lanoxin)
- B. Phenytoin (Dilantin)
- C. Warfarin (Coumadin)
- D. None of the above
Correct Answer: A
Rationale: Tetracyclines may increase the risk of toxicity in clients who take digoxin for heart disease and increase the risk of bleeding in clients who take warfarin.
A nurse suspects that a patient receiving an aminoglycoside is developing neurotoxicity based on assessment of which of the following? Select all that apply.
- A. Paresthesias
- B. Tingling around the mouth
- C. Ringing in the ears
- D. Vertigo
Correct Answer: A, B, E
Rationale: Signs and symptoms of neurotoxicity include numbness, skin tingling, circumoral (around the mouth) paresthesia, peripheral paresthesia, tremors, muscle twitching, convulsions, muscle weakness, and neuromuscular blockade (acute muscular paralysis and apnea). Ringing in the ears and vertigo would suggest ototoxicity.
A patient is ordered to receive neomycin as part of the treatment plan for hepatic coma. Which of the following would be most important for the nurse to assess before administering this drug? Select all that apply.
- A. Ability to swallow
- B. Level of consciousness
- C. Baseline vital signs
- D. Pulmonary function
Correct Answer: A, B
Rationale: During the early stages of hepatic coma, various changes in the level of consciousness may be seen. At times, the patient may appear lethargic and respond poorly to commands. Because of these changes in the level of consciousness, the patient may have difficulty swallowing, and a danger of aspiration is present. If the patient appears to have difficulty taking an oral drug, the nurse should withhold the drug and contact the primary health care provider. Baseline vital signs are important but are not the priority when the patient has hepatic coma. The drug does not affect the patient's respiratory function. There is no infection; therefore, there is no need for culture and sensitivity testing.
