Question

a nurse is preparing to administer meperidine 100 mg im stat. available is meperidine injection 75 mg/ml. how many ml should the nurse administer? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Identify formula for dosage calculation

To find the volume (in mL) to administer, we use the formula: \(\text{Volume (mL)}=\frac{\text{Desired Dose (mg)}}{\text{Available Concentration (mg/mL)}}\)

Step2: Substitute values into the formula

Desired dose \( = 100\space mg\), Available concentration \( = 75\space mg/mL\)
So, \(\text{Volume}=\frac{100}{75}\)

Step3: Calculate and round

\(\frac{100}{75}=\frac{4}{3}\approx1.3\) (rounded to the nearest tenth)

Answer:

\(1.3\)
