An intramuscular medication is given at 5.00 mg kg of body weight. What is the dose for a 160-Ib patient?
Express the mass in milligrams to two significant figures.
To convert the weight of a patient from pounds to kilograms, divide the weight in pounds by 2.2046 (number of pounds in a kilogram):
160 lb / 2.2046 lb/kg = 72.5748693 kg
To determine the dose for the patient, multiply the weight in kilograms by the medication dose per kilogram:
72.5748693 kg * 5.00 mg/kg = 362.874346 mg
Rounded to two significant figures: 360 mg
To calculate the dose for a 160-Ib patient, we need to convert their weight from pounds to kilograms.
1 pound (lb) is equal to 0.453592 kg.
So, the patient's weight in kilograms would be:
160 lb * 0.453592 kg/lb = 72.57472 kg
Now, we can calculate the dose for the patient. The dose is given as 5.00 mg per kg of body weight.
Dose = 5.00 mg/kg * 72.57472 kg
Dose ≈ 362.87 mg
Therefore, the dose for a 160-Ib patient is approximately 362.87 mg (rounded to two significant figures).
