A client is prescribed a drug as 0.3 mcg, q4h. Calculate the dose of the medicine per day.

The dose of the medicine per day is 1.8 mcg.

This answer is correct because it is based on a simple multiplication calculation. The nurse should follow these steps to calculate the dose of the medicine per day:

1) Divide 24 hours by the frequency of the dose to get the number of doses per day, as follows:

24 / 4 = 6

Therefore, the client will receive 6 doses of the medicine per day.

2) Multiply the number of doses per day by the amount of each dose to get the total dose per day, as follows:

6 x 0.3 mcg = 1.8 mcg

Therefore, the dose of the medicine per day is 1.8 mcg.

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**.
