Question

A physician orders 40 mg/m^2 of a drug. How many milligrams of the drug would you administer to an adult weighing 88 kg and having a height of 150 cm?

Answer 1

To calculate the amount of medication to administer, you need to calculate the body surface area (BSA) of the adult using the formula BSA (m^2) = (height (cm) x weight (kg)) / 3600. Then, multiply the BSA by the dose ordered to get the amount of drug to administer.

Step-by-step explanation:

To calculate the amount of medication to administer to an adult, we need to convert the dose from mg/m^2 to mg. First, we need to calculate the body surface area (BSA) of the adult using the formula:

BSA (m^2) = (height (cm) x weight (kg)) / 3600

Once we have the BSA, we can multiply it by the dose ordered to get the amount of drug to administer:

Drug amount (mg) = BSA (m^2) x Dose (mg/m^2)

In this case, the adult has a weight of 88 kg and a height of 150 cm. Let's calculate the BSA:

BSA = (150 cm x 88 kg) / 3600 = 3.67 m^2

Now let's calculate the amount of drug to administer:

Drug amount = 3.67 m^2 x 40 mg/m^2 = 146.8 mg
