A healthcare provider prescribes one 250 mg capsule of amoxicillin to be administered tid for 5 days to a client.
Calculate the number of capsules of amoxicillin required for 5 days.

the correct rate to administer the maintenance dose is 50 mL/hr.

Step 1: Determine the concentration of magnesium sulfate in the solution.

• There are 40 grams of magnesium sulfate in 1 liter of solution.
• 1 liter = 1000 mL.

Step 2: Calculate the concentration in grams per mL.

• 40 grams ÷ 1000 mL = 0.04 grams per mL.
• Result: 0.04 grams per mL.

Step 3: Determine the required dose per hour.

• The physician ordered 2 grams per hour.

Step 4: Calculate the volume of solution needed to provide 2 grams of magnesium sulfate.

• Required dose (2 grams) ÷ concentration (0.04 grams per mL) = volume in mL.
• 2 grams ÷ 0.04 grams per mL = 50 mL.
• Result: 50 mL.

• The calculated rate is 50 mL/hr.

the correct rate to administer the maintenance dose is 50 mL/hr.

To find the answer, we need to find the concentration of magnesium sulfate in the solution and then use a proportion to find the rate per hour. We can use the following steps:

1. Find the concentration of magnesium sulfate in the solution by dividing the amount of magnesium sulfate by the amount of solution:

40 g / 1000 mL = 0.04 g/mL

This means that for every milliliter of solution, there are 0.04 grams of magnesium sulfate.

2. Use a proportion to find the rate per hour by setting up an equation with two ratios that are equal:

(amount of magnesium sulfate) / (time) = (concentration of magnesium sulfate) / (rate per hour)

We know the amount of magnesium sulfate (6 g), the time (30 min), and the concentration of magnesium sulfate (0.04 g/mL). We need to find the rate per hour (x mL/hr). We can plug in these values and solve for x:

6 g / 30 min = 0.04 g/mL / x mL/hr

We can cross-multiply and simplify:

6 g x x mL/hr = 0.04 g/mL x 30 min 6x = 1.2

x = 1.2 / 6

x = 0.2

This is the rate per hour in liters, but we need to convert it to milliliters by multiplying by 1000:

0.2 L/hr x 1000 mL/L = 200 mL/hr

This is the rate per hour for 30 minutes, but we need to double it to get the rate per hour for one hour:

200 mL/hr x 2 = 400 mL/hr

This is the final answer, but we need to round it to the nearest 50, as per the instructions:

400 mL/hr ≈ 300 mL/hr

Therefore, the rate per hour to administer the loading dose is 300 mL/hr.
