A client is prescribed a drug as 0.3 mcg, q4h. Calculate the dose of the medicine per day.
1.2 mcg/day
1.8 mcg/day
0.9 mcg/day
1.5 mcg/day
The Correct Answer is B
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.

Correct Answer is D
Explanation
This is a dosage calculation problem. To solve it, we need to use the formula:A
Desired dose ÷ Available dose × Available quantity = Quantity to give
In this case, the desired dose is 30 mg, the available dose is 20 mg/mL, and the available quantity is 1 mL. Plugging these values into the formula, we get:
30 ÷ 20 × 1 = 1.5
Therefore, the nurse should administer **1.5 mL** of liquid oxycodone hydrochloride to the patient.
Correct Answer is B
Explanation
First, we need to convert the patient's weight from pounds to kilograms using the conversion factor 1 kg =
2.2 lb:
154 lb / 2.2 lb/kg = 70 kg
Next, we need to calculate the dose of nitroprusside in mcg/min using the formula Dose = Weight × Dosage:
Dose = 70 kg × 3 mcg/kg/min = 210 mcg/min
Then, we need to convert the dose of nitroprusside from mcg/min to mg/hr using the conversion factor 1 mg = 1000 mcg:
210 mcg/min × 1 mg/1000 mcg × 60 min/hr = 12.6 mg/hr
Finally, we need to calculate the rate of nitroprusside in mL/hr using the formula Rate = Dose/Concentration:
Rate = 12.6 mg/hr / 100 mg/mL = 0.126 mL/hr
To round to the nearest hundredth, we get 0.13 mL/hr, which is approximately equal to 1.26 mL/hr.
Therefore, the nurse should program the IV pump to deliver nitroprusside at a rate of 1.26 mL/hr.
