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 calculate the rate (in mL/hr) at which the IV pump should be programmed to deliver the dose of esmolol, we can use the following formula:
Rate (mL/hr) = (Dose × Patient weight × 60) / (Concentration × Time)
Given:
Dose = 2.5 grams Patient weight = 110 lb Concentration = 250 mL
Time = 1 hour (since the dose is given per hour)
Converting the patient's weight from pounds to kilograms:
Patient weight = 110 lb ÷ 2.2046 = 49.9 kg
Substituting the values into the formula:
Rate (mL/hr) = (2.5 g × 49.9 kg × 60) / (250 mL × 1)
Simplifying the equation:
Rate (mL/hr) = (2.5 × 49.9 × 60) / 250
Rate (mL/hr) = 74.85
Rounding to the nearest whole number, the nurse should program the IV pump to deliver 75 mL/hr.
Therefore, the correct answer is c. 75 mL/hr.
Correct Answer is A
Explanation
The nurse should administer 0.35 mcg of medication to the infant.
This answer is correct because it is based on a simple multiplication calculation. The nurse should multiply the prescribed dose per kilogram by the infant's weight in kilograms to get the total dose in micrograms, as follows:
0.05 mcg/kg x 7 kg = 0.35 mcg
Therefore, the nurse should administer 0.35 mcg of medication to the infant.
