Question

determine how many milligrams of acetaminophen to administer to a 150 lb adult patient. 68 mg 682 mg 1500 mg 3300 mg

Explanation:

Step1: Convert pounds to kilograms

1 lb = 0.453592 kg, so 150 lb = 150×0.453592 = 68.0388 kg

Step2: Calculate the dose of acetaminophen

Assume the dose is 10 - 15 mg/kg. Taking the middle - value of 12 mg/kg (if no specific dose per kg is given in the problem - context, this is a reasonable estimate for illustration). Then the dose = 68.0388×12 = 816.4656 mg. Another common approach is if we assume a standard dose and do a simple calculation. If we assume a typical adult dose range and do a rough estimate based on weight. A common starting point is to note that for a general adult dose calculation, and since we know some common adult acetaminophen doses. If we consider that a common adult dose is around 500 - 1000 mg for a standard - sized adult and we scale based on weight. But if we assume a more precise calculation based on the weight and a typical 10 mg/kg dose: 150 lb (68.0388 kg)×10 mg/kg = 680.388 mg which is closest to 682 mg.

Answer:

682 mg
