Question

a nurse is preparing to administer morphine 4 mg iv bolus every 3 hr prn pain. available is morphine injection 10 mg/ml. how many ml should the nurse administer per dose? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Identify the formula for dosage calculation

The formula to calculate the volume (in mL) of a medication to administer is: \(\text{Volume (mL)}=\frac{\text{Dose required (mg)}}{\text{Concentration (mg/mL)}}\)

Step2: Plug in the given values

The dose required is \(4\) mg, and the concentration of the morphine injection is \(10\) mg/mL. So we substitute these values into the formula:
\(\text{Volume}=\frac{4\space\text{mg}}{10\space\text{mg/mL}}\)

Step3: Perform the division

\(\frac{4}{10} = 0.4\)

Answer:

\(0.4\)
