Answer :
The nurse should administer 0.4 ml of ketorolac for the correct dosage.
To determine the correct dosage of ketorolac, we need to calculate how many milliliters will contain 20 mg of the medication.
Given that the pharmacy sent ketorolac 50 mg/1 ml, we can set up a proportion to find the answer:
50 mg/1 ml = 20 mg/x ml
Cross-multiplying, we get:
50 mg * x ml = 20 mg * 1 ml
Simplifying the equation:
50x = 20
Dividing both sides by 50:
x = 0.4 ml
Therefore, the nurse should administer 0.4 ml of ketorolac for the correct dosage.
