Question

a client receives a prescription for inamrinone 0.75 mg/kg iv bolus to be delivered over 3 minutes. the client weighs 80 kg. inamrinone is available for injection, 100 mg/20 ml. how many ml of inamrinone should the nurse administer? (enter numeric value only. if rounding is required, round to the nearest whole number.)

Explanation:

Step1: Calculate total mg needed

First, find the total milligrams of inamrinone required. The dosage is 0.75 mg/kg, and the client weighs 80 kg. So, multiply the dosage per kg by the weight: $0.75\ \text{mg/kg} \times 80\ \text{kg} = 60\ \text{mg}$.

Step2: Set up proportion for mL

Inamrinone is available as 100 mg/20 mL. Let $x$ be the volume in mL needed for 60 mg. Set up the proportion: $\frac{100\ \text{mg}}{20\ \text{mL}} = \frac{60\ \text{mg}}{x\ \text{mL}}$. Cross - multiply to get $100x = 60\times20$.

Step3: Solve for x

Calculate $60\times20 = 1200$. Then, $x=\frac{1200}{100}=12$.

Answer:

12
