A nurse is preparing to administer lidocaine via continuous IV infusion at 4 mg/min. Available is lidocaine 2 g dextrose 5% in water 500 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:
Sodium 141 mEq/L is incorrect. This value is within the normal range (usually around 135-145 mEq/L).
Choice B Reason:
Potassium 2.5 mEq/ is correct. Furosemide, a loop diuretic, can lead to potassium loss through increased urine output. If a client already has a low potassium level (hypokalemia), administering furosemide can further decrease potassium levels, potentially causing or worsening hypokalemia. Hypokalemia can lead to various complications, including cardiac arrhythmias.
Choice C Reason:
WBC count 8,000/mm3 is incorrect. This value falls within the normal range for white blood cell count.
Choice D Reason:
INR 1.0: An INR of 1.0 is within the normal range for a person not on anticoagulation therapy.

Choice A Reason:
"You should monitor for hearing difficulties." is correct. Loop diuretics like bumetanide can occasionally cause ototoxicity, resulting in hearing difficulties or ringing in the ears (tinnitus) as a potential adverse effect. It's important for clients taking these medications to be aware of such symptoms and report them promptly to their healthcare provider.
Choice B Reason:
"You should take the medication at bedtime." Is incorrect. Bumetanide is commonly prescribed to be taken in the morning to avoid nighttime diuresis and potential sleep disruption due to increased urination.
Choice C Reason:
"You should decrease your intake of foods high in potassium." Is incorrect. Loop diuretics often lead to potassium loss, so clients may actually need to increase their intake of potassium-rich foods or take potassium supplements under healthcare provider guidance to maintain normal potassium levels.
Choice D Reason:
"You should take this medication on an empty stomach." Is incorrect. Bumetanide can be taken with or without food, so it's not necessary to take it on an empty stomach.
