A physician orders Toradol (ketorolac) 30 mg IV push every 6 hours x 4 doses. A nurse has Toradol available as a 30 mg/mL injection.
How many millilitres per dose should the nurse administer to the patient?
0.6 mL
0.4 mL
1 mL
3 mL
The Correct Answer is C
The nurse should administer 1 mL per dose to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
30 mg / 1 mL = 30 mg / x mL
Cross-multiplying and solving for x gives:
x = 1 mL
Therefore, the nurse should administer 1 mL of Toradol injection to deliver 30 mg of the medication to the patient.

Correct Answer is B
Explanation
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 A
Explanation
To find the total amount of heparin, you need to calculate the following:
- The concentration of heparin in units per milliliter
- The volume of heparin infused from 9:00 am to 11:00 am and from 11:00 am to 2:00 pm
- The amount of heparin in units from each time period and the total amount
First, divide the amount of heparin by the volume of D5W to get the concentration in units per milliliter:
25,000 units / 250 mL = 100 units/mL
Next, multiply the infusion rate by the duration to get the volume infused in each time period:
From 9:00 am to 11:00 am (2 hours), the infusion rate is 12 mL/hr:
12 mL/hr x 2 hours = 24 mL
From 11:00 am to 2:00 pm (3 hours), the infusion rate is 10 mL/hr:
10 mL/hr x 3 hours = 30 mL
Then, multiply the volume infused by the concentration to get the amount of heparin in units in each time period:
From 9:00 am to 11:00 am, the volume infused is 24 mL:
24 mL x 100 units/mL = 2400 units
From 11:00 am to 2:00 pm, the volume infused is 30 mL:
30 mL x 100 units/mL = 3000 units
Finally, add the amounts of heparin from each time period to get the total amount:
2400 units + 3000 units = 5400 units
Therefore, the patient received **5400 units** of heparin from 9:00 am to 2:00 pm.
