Answer:
800 mg
Step-by-step explanation:
As the excerpt states that the client weights 176 pounds and is to receive cyclophosphamide (Cytoxan) 50 mg/kg, we have to convert 176 pounds to kg:
1 kg → 2.20 pounds
x ← 176 pounds
x= (176 pounds * 1 kg)/2.20 pounds= 80 kg
Now, we have to determine the total amount of cyclophosphamide (Cytoxan) that the client has to receive:
50 mg/kg
For 80 kg: 80 kg *50 mg/kg= 4,000 mg
As the dose is divided over 5 days:
4,000 mg / 5= 800 mg
The client will receive 800 mg of cyclophosphamide each day.
