Question

The nurse administers atropine sulfate, 0.4 mg intramuscularly, immediately. If the medication label indicates atropine sulfate, 0.3 mg/0.5 mL, how much medication does the nurse prepare? Round to the nearest tenth position.

A. 0.3 mL
B. 0.5 mL
C. 0.7 mL
D. 0.8 mL

Answer 1

To calculate the volume of medication needed, divide the desired dose by the concentration given on the medication label. After calculations, you round the result to the nearest tenth, which in this case is 0.7 mL. Hence, the correct answer is 0.7 mL.

Step-by-step explanation:

The student is asking how to calculate the volume of medication to prepare based on a given concentration and desired dose. The nurse needs to administer 0.4 mg of atropine sulfate and the medication label indicates that the concentration is 0.3 mg per 0.5 mL. To find the volume of medication (V) to prepare, we use the formula:

V = (desired dose) / (concentration)

Which translates to:

V = 0.4 mg / (0.3 mg/0.5 mL)

Performing the calculation:

V = 0.4 mg / (0.3 mg/0.5 mL) = (0.4 mg * 0.5 mL) / 0.3 mg

V = (0.2 mL) / 0.3

V ≈ 0.6667 mL

Rounded to the nearest tenth, the volume of medication the nurse needs to prepare is 0.7 mL.

Therefore, the correct answer is C. 0.7 mL.
