Explanation:
The question involves calculating the dosage of cefdinir for a child based on their weight and the recommended dosing guidelines.
Firstly, convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 44 lb, so their weight in kilograms is 44 lb ÷ 2.2 = 20 kg.
Next, multiply the weight in kilograms by the recommended dose, 7 mg/kg, to find the total dosage per dose. Therefore, 20 kg × 7 mg/kg = 140 mg. Hence, the nurse should plan to administer 140 mg per dose to the child.
