Question

A) 4,500 units
B) 5,000 units
C) 9,000 units
D) 10,000 units

Answer 1

After converting the client's weight from pounds to kilograms, and multiplying by the prescribed dose of
`100 units/kg` , the nurse should administer
`9,000 units` of IV Heparin to the client, which is the closest option to the calculated value.

Step-by-step explanation:

The nurse plans to administer a bolus dose of IV Heparin based on the client's weight.

To calculate the dosage, it's necessary to convert the client's weight from pounds to kilograms since the prescribed bolus dose is
`100 units/kg.`

First, we convert the client's weight of
`198 pounds` to kilograms by dividing by
`2.2046` (since 1 kilogram equals
`2.2046 pounds`).

`198 pounds ÷ 2.2046 = 89.81 kilograms` (rounded to two decimal places).

Next, we calculate the number of units of Heparin by multiplying the client's weight in kilograms by the prescribed dose:

`89.81 kg × 100 units/kg = 8981 units.`

Since medication dosages are typically rounded to the nearest whole number, the nurse should administer
`8981 units` , which is not an option in the provided choices. However, the closest matching option to the accurately calculated dose is Option C,
`9,000 units`.
