Answer :
The patient weighs approximately 74.8 kg, based on a prescribed dosage of 10 mg of an antibiotic per kilogram of body weight for a patient weighing 165 lb.
To convert pounds to kilograms, we use the conversion factor 1 lb = 0.45359237 kg.
The patient's weight is 165 lb, we can calculate the weight in kilograms as follows:
Weight in kg = 165 lb × 0.45359237 kg/lb ≈ 74.8 kg
In medical practice, dosages of medications are often prescribed based on a patient's body weight. The given prescription of 10 mg of an antibiotic per kilogram of body weight implies that the appropriate dose of the antibiotic is directly proportional to the patient's weight. This is a common practice as it helps adjust the medication amount to the individual's specific physiological characteristics.
The conversion from pounds (lb) to kilograms (kg) is essential because most medical measurements, including medication dosages, are standardized in metric units. The conversion factor, 0.45359237 kg/lb, is used to convert weight from pounds to kilograms.
When the patient's weight is 165 lb, applying the conversion factor yields a weight of approximately 74.8 kg. This means that the patient's body weight in kilograms is around 74.8 kg, and the prescribed antibiotic dosage will be calculated based on this weight to ensure proper treatment without under-dosing or over-dosing.
