An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg

= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.

2.   Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3.   Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4.   Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5.   Round the volume to the nearest tenth= 1.3 mL

Correct Answer is C

Explanation

A) Incorrect- Furosemide is a loop diuretic used to treat conditions such as edema and hypertension. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
B) Incorrect- Low-dose aspirin is often used for its antiplatelet effects to prevent cardiovascular events. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
C) Correct- Allopurinol is a medication used to treat gout by reducing the production of uric acid in the body. However, allopurinol can also increase the risk of forming calcium oxalate kidney stones, which is the type of kidney stone mentioned in the client's history. Calcium oxalate stones are the most common type of kidney stone, and they are composed primarily of calcium and oxalate. In this case, the client has a history of gout and is prescribed allopurinol. The nurse should bring the client's prescription for allopurinol to the healthcare provider's attention because

it has the potential to contribute to the formation of kidney stones, which could exacerbate the client's existing condition.
D) Incorrect- Enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension and heart failure. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
