Question

a client receives a prescription for ondansetron hydrochloride 4 mg iv to prevent postoperative nausea after an inguinal hernia repair. the medication is available in 2 mg/ml. how many ml should the nurse administer? (enter numerical value only. if rounding is required, round to nearest whole number).

Explanation:

Step1: Identify formula for volume

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

Step2: Substitute values into formula

The dose required is 4 mg, and the concentration is 2 mg/mL. Substituting these values, we get: \( \text{Volume} = \frac{4\ \text{mg}}{2\ \text{mg/mL}} \)

Step3: Calculate the volume

Simplifying the expression, \( \frac{4}{2} = 2 \) mL.
