A patient who takes the loop diuretic ethacrynic acid is given intravenous gentamicin for an infection.

Answer to Question 1

B
Ethacrynic acid has ototoxic properties, and patients who take this drug with an aminoglycoside have an increased risk of ototoxicity, especially when trough levels of the aminoglycoside are elevated. A trough level of 2.1 mcg/mL is above normal limits for gentamicin, so this patient should be asked about early signs of ototoxicity. There is no indication to evaluate for GI symp-toms, rash, or urine output.

Answer to Question 2

A, D, E
Adverse effects of nicotinic acid include intense flushing of the face, neck, and ears; itching; and GI upset (nausea, vomiting, and diarrhea). Constipation and hypoglycemia are not adverse ef-fects of niacin therapy.
