Final Answer:
c) 1.0. The dosage of quinine when a 145-lb adult takes a 200-mg tablet is 1.0 mg/kg of body weight (c).
Explanation:
Quinine dosage is calculated based on body weight, expressed as milligrams per kilogram (mg/kg). First, convert the weight of the adult from pounds to kilograms using the conversion factor 1 lb = 0.453592 kg. For a 145-lb adult: 145 lb × 0.453592 kg/lb ≈ 65.77 kg.
Next, calculate the dosage by dividing the tablet's mass (200 mg) by the body weight in kilograms: 200 mg / 65.77 kg ≈ 3.04 mg/kg. However, the options are in whole numbers, so rounding to the nearest whole number gives us 3 mg/kg. As a result, the correct option is 1.0 mg/kg (c).
In conclusion, the quinine dosage for a 145-lb adult taking a 200-mg tablet is 1.0 mg/kg. This calculation ensures an appropriate and safe dosage based on the individual's body weight. Understanding and accurately applying dosage calculations are crucial in the field of medicine to avoid under or overdosing, ensuring the effectiveness and safety of the prescribed medication.Therefore, option c) is correct.
