A patient admitted with an infected right stump secondary to a below-the-knee amputation (BKA) also has heart failure. The patient is taking gentamicin (Garamycin) and furosemide (Lasix). What patient education should the nurse include?
a. Report any ringing in the ears or dizziness.
b. Report frequent nocturia.
c. Elevate the affected extremity.
d. Immediately report any tendon tenderness.
ANS: A
The risk of furosemide-induced hearing loss is increased by concurrent use of other ototoxic drugs, especially aminoglycoside antibiotics, such as gentamicin. Ringing in the ears or dizziness may indicate impending or actual cochlear damage.
Some nocturia may be expected, especially if furosemide is given late in the evening.
Elevating the extremity helps alleviate swelling but does not address the intent of the question.
Tendonitis is not associated with aminoglycoside or diuretic therapy.
