To determine the proper dose of Isoniazid for a patient weighing 196 lb, first convert their weight to kilograms (approximately 88.90 kg). Then, multiply by the dosing guideline of 15 mg/kg, resulting in a dose of about 1333.5 mg. This is the recommended dosage to treat Tuberculosis.

Explanation:

Dosing Isoniazid for Tuberculosis Treatment

Isoniazid is an antibiotic commonly used to treat Tuberculosis. To determine the appropriate dose for a patient weighing 196 lb, we first need to convert their weight from pounds to kilograms, as the dosage is calculated based on body weight in kg.

Convert weight: 196 lb to kg
1 lb is approximately 0.453592 kg, so:
196 lb × 0.453592 kg/lb ≈ 88.90 kg
Calculate the dosage:
The recommended dose is 15 mg of Isoniazid per kg of body weight:
88.90 kg × 15 mg/kg = 1333.5 mg

Therefore, the proper dose to administer is approximately 1333.5 mg of Isoniazid for a patient weighing 196 lb.
