Answer to Question 1

ANS: B
Polymyxins can cause nephrotoxicity and neurotoxicity. This patient has signs of neurotoxicity, so the nurse should notify the provider. These effects are generally reversible when the drug is discontinued. It is not correct to administer the drug when these symptoms are present. Polymyxins are not absorbed orally. Serum electrolytes are not indicated.

Answer to Question 2

ANS: B
Streptomycin can cause significant renal toxicity.
