A nurse is preparing to administer hydrocortisone 7.5 mg PO to a child. The amount available is hydrocortisone 5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.5"]

To administer the correct dose of hydrocortisone, which is 7.5 mg, when only 5 mg tablets are available, the nurse would need to give one and a half tablets to achieve the desired dose. 7.5 mg divided by 5 mg per tablet equals 1.5 tablets.

Correct Answer is ["2"]

Explanation

To calculate the dosage of haloperidol for the child, first determine the total daily dose by multiplying the child's weight by the prescribed amount per kilogram. For a child weighing 40 kg, this would be 0.15 mg/kg/day * 40 kg, which equals 6 mg/day. Since the medication is to be administered in divided doses every 8 hours, divide the total daily dose by the number of doses per day. There are 24 hours in a day, so with doses every 8 hours, that's 3 doses per day. Therefore, 6 mg/day divided by 3 doses per day equals 2 mg per dose.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate for an IV, you would divide the total volume of IV fluid (1,000 mL) by the time in hours over which the infusion is to run (12 hr). This calculation gives you the rate in mL/hr. So, for 1,000 mL of sodium chloride to be infused over 12 hours, the calculation is 1,000 divided by 12, which equals approximately 83.33 mL/hr. When rounding to the nearest whole number, the IV pump should be set to deliver 83 mL/hr.
