A nurse is preparing to administer potassium chloride 30 mEq PO daily. The amount available is potassium chloride 20 mEq/15mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["23"]
To determine how many milliliters (mL) of potassium chloride the nurse should administer to provide 30 mEq, we can set up a proportion:
20 mEq is contained in 15 mL. So, to find out how many mL contain 30 mEq, we can set up the proportion:
20 mEq:15 mL=30 mEq:? mL20mEq:15mL=30mEq:xmL
Cross multiply:
20×?=15×3020×x=15×30
20?=45020x=450
Now, solve for ?x:
?=45020x=20450
?=22.5x=22.5
So, the nurse should administer approximately 22.5 mL of potassium chloride.
Rounded to the nearest whole number, this would be 23 mL.
Therefore, the nurse should administer 23 mL of potassium chloride.
