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 D
Explanation
The nurse should administer 4 mL to this 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:
2 mg / 1 mL = 8 mg / x mL
Cross-multiplying and solving for x gives:
x = 4 mL
Therefore, the nurse should administer 4 mL of ondansetron to deliver 8 mg of the medication to the patient.
Correct Answer is A
Explanation
To find the number of capsules of amoxicillin required for 5 days, you need to calculate the following:
- The total dose of amoxicillin in milligrams (mg) for 5 days using the formula: Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
- The number of capsules of amoxicillin using the formula: Number of capsules = Total dose (mg) / Strength per capsule (mg)
First, use the formula for total dose to find the amount of amoxicillin in milligrams for 5 days:
Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
Since the prescribed dose is 250 mg, the frequency is 3 times per day, and the duration is 5 days, plug in these values into the formula:
Total dose (mg) = 250 mg x 3 times/day x 5 days
Simplify and solve for the total dose:
Total dose (mg) = 3750 mg
Next, use the formula for number of capsules to find how many capsules of amoxicillin are needed:
Number of capsules = Total dose (mg) / Strength per capsule (mg)
Since the total dose is 3750 mg and the strength per capsule is 250 mg, plug in these values into the formula:
Number of capsules = 3750 mg / 250 mg
Simplify and solve for the number of capsules:
Number of capsules = 15
Therefore, the client needs **15 capsules** of amoxicillin for 5 days.
