Final answer:
Among the effects listed, a urinary output of 70 mL/2 hr after administration of amphotericin B indicates a possible adverse reaction linked to nephrotoxicity and decreased renal function.
Step-by-step explanation:
A student is questioning which finding might indicate an adverse reaction to the medication amphotericin B when given via intermittent IV bolus. Among the listed possible outcomes, urinary output 70 mL/2 hr is notably concerning and can be indicative of an adverse effect. Amphotericin B is known to cause nephrotoxicity, which can lead to renal damage and reduced urinary output. Therefore, a urinary output of 70 mL over 2 hours could suggest that renal function might be compromised. Regular monitoring of renal function, including urinary output, is crucial when administering amphotericin B.
