Final answer:
The nurse would be most concerned about the potential side effects of aminoglycoside, including ototoxicity, nephrotoxicity, and neuromuscular blockade.
Step-by-step explanation:
When caring for a patient with an infection being treated with an aminoglycoside, the nurse would be most concerned about certain findings that could indicate potential harmful side effects of the medication. These findings include:
Ototoxicity: Aminoglycosides can cause damage to the inner ear, leading to hearing loss or balance problems. The nurse should monitor the patient for any signs of hearing difficulties or vertigo.
Nephrotoxicity: Aminoglycosides can also harm the kidneys, leading to acute kidney injury. The nurse should monitor the patient's urine output, as well as perform periodic lab tests to assess kidney function.
Neuromuscular blockade: Aminoglycosides can interfere with neuromuscular transmission, causing muscle weakness or paralysis. The nurse should assess the patient's muscle strength and respiratory status regularly.
