Question

a nurse is preparing to administer meperidine 75 mg subcutaneous every 4 hr prn pain. available is meperidine injection 100 mg/ml. how many ml should the nurse administer per dose? (round the answer to the nearest hundredth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Identify the formula for dosage calculation

The formula for calculating the volume of medication to administer is \( \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Available Dose (mg/mL)}} \). Here, the desired dose is 75 mg and the available dose is 100 mg/mL.

Step2: Substitute the values into the formula

Substitute the desired dose (75 mg) and the available concentration (100 mg/mL) into the formula: \( \text{Volume} = \frac{75}{100} \).

Step3: Calculate the result

\( \frac{75}{100} = 0.75 \).

Answer:

0.75
