This is important to prevent bleeding at the insertion site and ensure proper healing.

Rationale: To calculate the correct dosage, first convert the infant's weight to kilograms: 17.6 lb = 8 kg. The prescribed dose is 5 mg/kg, so for an 8 kg infant, the total dose required is 40 mg. Since the available ibuprofen liquid is 100 mg/5 ml, to find out how many milliliters to administer, divide the total dose (40 mg) by the concentration of the liquid (100 mg/5 ml), which equals 2 ml. Therefore, the healthcare provider should administer 2 ml of ibuprofen to the infant.
