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 B
Explanation
To find the flow rate in mL/hr, you need to use the formula for infusion rate:
Infusion rate (mL/h) = Total volume (mL) / Time (h)
Since the total volume is 2.5 L and the time is 15 hours, plug in these values into the formula:
Infusion rate (mL/h) = 2.5 L / 15 h
However, before you can simplify and solve for the infusion rate, you need to convert the volume from liters to milliliters by multiplying by 1000:
Infusion rate (mL/h) = 2500 mL / 15 h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 166.67 mL/h
Therefore, the flow rate for continuous infusion is **166.67 mL/h**.
Correct Answer is A
Explanation
To calculate the dose in milligrams per hour, we need to convert the patient's weight from pounds to kilograms.
Patient's weight: 110 lb
To convert pounds to kilograms, we use the conversion factor: 1 lb = 0.4536 kg
Patient's weight in kilograms: 110 lb * 0.4536 kg/lb = 49.895 kg (rounded to 3 decimal places
The physician has ordered Dobutamine at a dose of 10 mcg/kg/min.
Dose required = 10 mcg/kg/min * 49.895 kg = 498.95 mcg/min
Next, we need to convert the dose from micrograms to milligrams.
498.95 mcg/min = 0.49895 mg/min
Finally, to determine the dose in milligrams per hour, we multiply the dose in milligrams per minute by 60 minutes to convert it to an hourly rate.
0.49895 mg/min * 60 min/hr = 29.937 mg/hr (rounded to 3 decimal places)
Therefore, the correct answer is:
a. 30 mg/hr
