A primary healthcare provider has prescribed ertapenem to a 6-year-old child with a urinary tract infection (UTI).
What is the safe dose of medication for this child?

To find the maximum number of tablets the patient may have in 24 hours, you need to calculate the following:

- The number of doses the patient may have in 24 hours using the formula: Number of doses = 24 hours / Dosing interval (hours)
- The total dose of ibuprofen in milligrams (mg) for 24 hours using the formula: Total dose (mg) = Number of doses x Prescribed dose (mg)
- The number of tablets of ibuprofen using the formula: Number of tablets = Total dose (mg) / Strength per tablet (mg)

First, use the formula for number of doses to find how many times the patient may take ibuprofen in 24 hours:

Number of doses = 24 hours / Dosing interval (hours)

Since the dosing interval is 6 hours, plug in this value into the formula:

Number of doses = 24 hours / 6 hours

Simplify and solve for the number of doses:

Number of doses = 4

Next, use the formula for total dose to find the amount of ibuprofen in milligrams for 24 hours:

Total dose (mg) = Number of doses x Prescribed dose (mg)

Since the number of doses is 4 and the prescribed dose is 600 mg, plug in these values into the formula:

Total dose (mg) = 4 x 600 mg

Simplify and solve for the total dose:

Total dose (mg) = 2400 mg

Then, use the formula for number of tablets to find how many tablets of ibuprofen are needed:

Number of tablets = Total dose (mg) / Strength per tablet (mg)

Since the total dose is 2400 mg and the strength per tablet is 200 mg, plug in these values into the formula:

Number of tablets = 2400 mg / 200 mg

Simplify and solve for the number of tablets:

Number of tablets = 12

Therefore, the maximum number of tablets the patient may have in 24 hours is **12**.

To find the number of capsules of amoxicillin required for 5 days, you need to calculate the following:

- The total dose of amoxicillin in milligrams (mg) for 5 days using the formula: Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
- The number of capsules of amoxicillin using the formula: Number of capsules = Total dose (mg) / Strength per capsule (mg)

First, use the formula for total dose to find the amount of amoxicillin in milligrams for 5 days:

Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)

Since the prescribed dose is 250 mg, the frequency is 3 times per day, and the duration is 5 days, plug in these values into the formula:

Total dose (mg) = 250 mg x 3 times/day x 5 days

Simplify and solve for the total dose:

Total dose (mg) = 3750 mg

Next, use the formula for number of capsules to find how many capsules of amoxicillin are needed:

Number of capsules = Total dose (mg) / Strength per capsule (mg)

Since the total dose is 3750 mg and the strength per capsule is 250 mg, plug in these values into the formula:

Number of capsules = 3750 mg / 250 mg

Simplify and solve for the number of capsules:

Number of capsules = 15

Therefore, the client needs **15 capsules** of amoxicillin for 5 days.
