Answer to Question 1

D
Fish oil may be beneficial in prevention of heart dysrhythmias in patients who have had myocar-dial infarction or heart failure. It has not shown to be beneficial in decreasing cholesterol, reduc-ing the risk of thrombotic stroke, or preventing heart disease.

Answer to Question 2

D
The aminoglycosides are eliminated primarily by the kidneys, so in patients with renal disease, doses should be reduced or the dosing interval should be increased to prevent toxicity. Patients with antibiotic resistance would be given amikacin. Interpatient variation may occur but cannot be known without knowing current drug levels. Aminoglycosides are not metabolized by the liv-er, so liver disease would not affect drug levels.
