Final answer:
To administer a 60mg dose of Lasix when the supply is 20mg per 2ml, 6ml of the medication should be given.
Step-by-step explanation:
The subject of the question involves calculating the correct dosage of a medication, which in this case is Lasix (furosemide), used for the treatment of edema and heart failure. The question asks how many milliliters of Lasix should be given if a single dose of 60mg IV stat is ordered, and the supply available is Lasix 20mg per 2 ml. To answer this, we need to determine how many millilitres contain the required 60mg dose. Since every 2 ml of the supply contains 20mg, we divide the ordered dose by the concentration per milliliter. To administer a 60mg dose, we need 6 ml since 60mg / (20mg/2ml) = 6ml.
