The nurse is caring for an infant who weighs 16 kg. Calculate the daily maintenance fluid requirement for this child. Round to the nearest whole number.

Choice A reason: Lispro (Humalog) is a type of insulin that is used for mealtime coverage. It is a rapid-acting insulin that starts to work within 15 minutes, peaks in about an hour, and lasts for 2 to 4 hours. It mimics the natural insulin response to food intake, and helps to lower the blood glucose level after meals. The nurse will discuss using lispro for mealtime coverage, and instruct the patient to inject it within 15 minutes before or after eating.

Choice B reason: NPH (Humulin N) is a type of insulin that is not used for mealtime coverage. It is an intermediate-acting insulin that starts to work within 2 to 4 hours, peaks in 4 to 12 hours, and lasts for 12 to 18 hours. It provides a steady background of insulin throughout the day, and helps to control the blood glucose level between meals and overnight. The nurse will discuss using NPH for basal coverage, and instruct the patient to inject it once or twice a day, usually in the morning and/or evening.

Choice C reason: Detemir (Levemir) is a type of insulin that is not used for mealtime coverage. It is a long-acting insulin that starts to work within 1 to 2 hours, has no peak, and lasts for up to 24 hours. It provides a constant level of insulin throughout the day, and helps to maintain the blood glucose level at a stable range. The nurse will discuss using detemir for basal coverage, and instruct the patient to inject it once or twice a day, depending on the individual needs.

Choice D reason: Glargine (Lantus) is a type of insulin that is not used for mealtime coverage. It is a long-acting insulin that starts to work within 1 to 2 hours, has no peak, and lasts for up to 24 hours. It provides a constant level of insulin throughout the day, and helps to maintain the blood glucose level at a stable range. The nurse will discuss using glargine for basal coverage, and instruct the patient to inject it once a day, usually at the same time every day.

Choice A reason: This statement is false. A serum potassium level of 5.6 mEq/L is not a common side effect of furosemide. This value indicates hyperkalemia, or high blood potassium level, which can cause cardiac arrhythmias and muscle weakness. Furosemide is a loop diuretic that causes potassium loss, not retention.

Choice B reason: This statement is false. A serum sodium level of 142 mEq/L is not a common side effect of furosemide. This value is within the normal range of 135-145 mEq/L and does not indicate any problem with sodium balance. Furosemide is a loop diuretic that causes sodium loss, but it is usually compensated by the renin-angiotensin-aldosterone system.

Choice C reason: This statement is false. A serum sodium level of 138 mEq/L is not a common side effect of furosemide. This value is within the normal range of 135-145 mEq/L and does not indicate any problem with sodium balance. Furosemide is a loop diuretic that causes sodium loss, but it is usually compensated by the renin-angiotensin-aldosterone system.

Choice D reason: This statement is true. A serum potassium level of 2.8 mEq/L is a common side effect of furosemide. This value indicates hypokalemia, or low blood potassium level, which can cause cardiac arrhythmias, muscle weakness, and metabolic alkalosis. Furosemide is a loop diuretic that inhibits the reabsorption of sodium and potassium in the ascending loop of Henle, leading to potassium loss in the urine.
