Feedback:
First, using the formula: 2.2 pounds and 52 pounds: times kg, determine the child's weight in kg (52/2.2 = 23.64). Next, using the formula of amount of drug prescribed times weight in kg, determine the amount the child will receive in one dose (4 times 23.64 = 94.56). To determine the mg in a 12-hour period multiply 94.56 times 3 = 283.68 . Round to 284 mg. Options A, B, and D are not correct.
