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 infusion will be completed at 3:15 p.m.

This answer is correct because it is based on a simple division and addition calculation. The nurse should follow these steps to determine when the infusion will be completed:

1) Convert the volume of the fluid from liters to milliliters by multiplying by 1000, since there are 1000 mL in 1 L. The volume of the fluid is 750 mL.

2) Divide the volume of the fluid by the infusion rate to get the duration of the infusion in hours, as follows:

750 mL / 120 mL/hr = 6.25 hr

Therefore, the infusion will take 6.25 hours to complete.

3) Add the duration of the infusion to the start time of the infusion to get the end time, as follows:

9:00 a.m. + 6:25 = 3:15 p.m.

Therefore, the infusion will be completed at 3:15 p.m.

This answer is correct because it is based on a series of unit conversions and calculations. The nurse should follow these steps to provide safe medication to the child:

1) Convert the child's weight from pounds to kilograms by dividing by 2.2, since there are 2.2 lbs in 1 kg. The child weighs 20 kg.

2) Multiply the prescribed dose per kilogram by the child's weight in kilograms to get the total dose in milligrams. The child needs 40 mg of pyrimethamine.

3) Use the ratio given on the drug label to convert the total dose in milligrams to the volume in milliliters. The nurse can set up a proportion as follows:

1 mg / 5 mL = 40 mg / x mL

Cross-multiplying and solving for x gives:

x = 200 mL

Therefore, the nurse should administer 200 mL of medication to deliver 40 mg of pyrimethamine to the child.

4) Convert the volume in milliliters to the volume in teaspoons by dividing by 5, since there are 5 mL in 1 tsp. The nurse should administer 40 tsp of medication to the child.

5) Convert the volume in teaspoons to the volume in cups by dividing by 48, since there are 48 tsp in 1 cup. The nurse should administer 0.83 cups of medication to the child.
