Answer :
Final answer:
After converting the patient's weight from pounds to kilograms, multiply the weight in kilograms by the ordered dose per kilogram. The calculated dose of Midazolam for a 15-year-old patient weighing 112 lb at 0.025 mg\/kg is approximately 1.25 mg, matching option C.
Explanation:
To calculate the dosage of Midazolam for a 15-year-old patient weighing 112 lb, we must first convert the patient's weight from pounds to kilograms. We know that 1 kilogram is equal to approximately 2.2 pounds. Therefore, the patient's weight in kg is 112 lb \/ 2.2 lb\/kg, which equals approximately 50.91 kg.
Next, we calculate the total dosage of Midazolam needed using the ordered dose of 0.025 mg\/kg. Multiply the patient's weight in kilograms by the ordered dose per kilogram: 50.91 kg \\* 0.025 mg\/kg equals 1.27275 mg.
When rounding to the nearest available dose option, the amount to administer to the patient is 1.25 mg, which closely matches option C.
