A nurse is instructed to administer 60 mEq of an iron supplement to an anemic client three times a day. The iron supplement botle contains 30 mEq in 10 mL.
How many milliliters of the supplement should the nurse administer in a day?
20 mL
60 mL
30 mL
10 mL
The Correct Answer is B
The nurse should administer 60 mL of the supplement in a day.
This answer is correct because it is based on a simple unit conversion and multiplication calculation. The nurse can convert 60 mEq to 20 mL by using the ratio given on the botle label, as follows:
30 mEq / 10 mL = 60 mEq / x mL
Cross-multiplying and solving for x gives:
x = 20 mL
Therefore, the nurse should administer 20 mL of the supplement to deliver 60 mEq of the medication to the patient. Since the order is for three times a day, the nurse should multiply 20 mL by 3 to get the total daily dose, which is 60 mL.

Correct Answer is C
Explanation
To find the milliliters per minute, you need to calculate the following:
- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)
First, divide the dose of Lopressor by the concentration to get the volume in milliliters:
5 mg / 1 mg/mL = 5 mL
Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:
Infusion rate (mL/min) = Total volume (mL) / Time (min)
Since the total volume is 5 mL and the time is 60 seconds or 1 minute, plug in these values into the formula:
Infusion rate (mL/min) = 5 mL / 1 min
Simplify and solve for the infusion rate:
Infusion rate (mL/min) = 5 mL/min
Therefore, the nurse should administer **5 mL/min** to infuse Lopressor 5 mg over 60 seconds.
Correct Answer is C
Explanation
The nurse should administer 12.5 mL of amoxicillin oral suspension.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
200 mg / 5 mL = 500 mg / x mL
Cross-multiplying and solving for x gives:
x = 12.5 mL
Therefore, the nurse should administer 12.5 mL of amoxicillin oral suspension to deliver 500 mg of the medication to the patient.
