Final answer:
To find the amount of acyclovir to be administered, we convert the patient's weight to kg, multiply by the order of 12 mg/kg, and then solve a proportion to find the volume in ml. The answer is 12.42 ml.
Step-by-step explanation:
To find the amount of acyclovir that needs to be administered, we first need to convert the patient's weight from lbs to kg. Since 1 lb is approximately 0.45 kg, the patient's weight in kg is 115 lbs * 0.45 kg/lb = 51.75 kg.
Next, we can use the order of 12 mg/kg to find the total amount of acyclovir needed. Multiply the patient's weight in kg by the dose per kg: 51.75 kg * 12 mg/kg = 621 mg.
Finally, we can determine the volume of the medication to be administered. Since the supply is given in mg per 2 ml, we can set up a proportion: 100 mg/2 ml = 621 mg/x ml. Cross-multiplying and solving for x gives us x = (621 mg * 2 ml) / 100 mg = 12.42 ml. Therefore, 12.42 ml of acyclovir will be administered.
