Question

a nurse is preparing to administer morphine 5 mg subcutaneous every 4 hr prn pain. available is morphine 10 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 the formula for dosage calculation

The formula for calculating the volume of medication to administer is \( \text{Volume (mL)}=\frac{\text{Dose Ordered (mg)}}{\text{Concentration (mg/mL)}} \). Here, the dose ordered is 5 mg and the concentration is 10 mg/mL.

Step2: Substitute the values into the formula

Substitute the given values into the formula: \( \text{Volume}=\frac{5\space\text{mg}}{10\space\text{mg/mL}} \)

Step3: Perform the calculation

Simplify the fraction: \( \frac{5}{10} = 0.5 \)

Answer:

0.5
