Question

Ordered: amoxicillin 0.15 g POq8h for a patient with cystitis. The suspension contains 200 mg amoxicillin per 5.0 ml solution. How many ml. per dose? volume =

Answer 1

To administer a 0.15 g dose of amoxicillin, convert the dose into milligrams (150 mg) and calculate the volume needed using the concentration of the suspension (200 mg/5 ml), resulting in 3.75 ml per dose.

Step-by-step explanation:

The question asks how many milliliters per dose of amoxicillin suspension should be given to a patient, based on the prescribed amount and the concentration of the suspension. To find the volume needed for each dose, we need to convert the ordered amount of amoxicillin from grams to milligrams and then use the concentration of the suspension to calculate the final volume.

First, we convert the ordered amoxicillin from grams to milligrams:

Next, since the suspension contains 200 mg of amoxicillin per 5.0 ml, we set up a proportion to find out how many milliliters are needed for a 150 mg dose:

• (200 mg / 5 ml) = (150 mg / x ml)
• x = (150 mg × 5 ml) / 200 mg
• x = 750 / 200
• x = 3.75 ml

So, for each dose, the patient should receive 3.75 ml of the amoxicillin suspension.

Answer 2

3.75 ml per dose

Step-by-step explanation:

We need to convert the units from g to mg and then perform a cross-multiplication.

The concentration of the drug is 200 mg/ 5.0 ml

200 mg = 0.2 g (because 1 g equals 1000 mg)

`(0.2 g)/(5 ml) =(0.15 g)/(x) \\ x= (0.15 g *5 ml)/(0.2 g)`

x = 3.75 ml
