Final answer:
The nurse will monitor carefully for nephrotoxicity as a potential effect from the interaction of aminoglycoside antibiotics and furosemide (Lasix).
Step-by-step explanation:
The nurse will monitor carefully for nephrotoxicity as a potential effect from the interaction of these two drugs. Aminoglycoside antibiotics, like those used to treat pneumonia, can have nephrotoxic effects, and loop diuretics like furosemide can also cause kidney damage. The combination of these drugs may increase the risk of kidney damage, so close monitoring is necessary.
