The healthcare provider prescribes amoxicillin 5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, "Amoxicillin suspension 200 mg/5 mL."
How many mL should the nurse administer every 8 hours?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["41.7"]
Step 1: Convert grams to milligrams
The prescribed dose is 5 grams (g) daily.
- 1 gram (g) = 1,000 milligrams (mg)
- 5 g = 5,000 mg daily
Step 2: Determine the dose per administration
The medication is to be given every 8 hours, meaning the total daily dose is divided into three equal doses:
5,000 mg/3=1,666.67 mg per dose
Step 3: Use the medication concentration to find the volume
The available suspension is 200 mg per 5 mL. Using the ratio formula:
200 mg/5 mL=1,666.67 mg/X mL
Solve for X:
X=1,666.67×5/200
X=8,333.35/200=41.67 mL
Answer: 41.7 mL (Rounded off to the nearest tenth)
