Final answer:
The dose of ganciclovir for a patient weighing 110 pounds is 250 mg per day to treat a Cytomegalovirus (CMV) infection.
Step-by-step explanation:
To calculate the dose of ganciclovir for a patient weighing 110 pounds to treat a Cytomegalovirus (CMV) infection, we must first convert the patient's weight from pounds to kilograms. Since there are approximately 2.2 pounds in a kilogram, the patient's weight in kilograms is 110 pounds ÷ 2.2 pounds/kg, which equals 50 kilograms. The prescribed dose of ganciclovir is 5 mg/kg/day. Therefore, the patient will receive 5 mg/kg × 50 kg, which equals 250 mg of ganciclovir per day.
