Final answer:
To calculate the amount of medicine per dose, convert the weight from pounds to kilograms. Then, multiply the weight in kilograms by the dosage instruction. Finally, divide the total daily dosage by the number of doses to get the amount of medicine per dose.
Step-by-step explanation:
To calculate the amount of medicine that should be given per dose, we need to first convert the weight of the patient from pounds to kilograms. The patient weighs 196 pounds, which is approximately equal to 88.9 kilograms.
The dosage instruction calls for 20 mL of medicine per kilogram of body weight per day. Since the medicine will be given in 7 doses per day, we can calculate the amount of medicine per dose by dividing the total daily dosage by the number of doses. In this case, the total daily dosage is 20 mL/kg * 88.9 kg = 1778 mL. Dividing this by 7 doses gives us approximately 254 mL per dose.
Therefore, approximately 254 mL of medicine should be given per dose.
