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.)
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 ["30"]
Explanation
To calculate the dosage of dexamethasone in milliliters for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 66 pounds, which is approximately 30 kilograms (66 / 2.2). According to the prescription, the child requires 0.2 mg of dexamethasone per kilogram per day. So, for a 30 kg child, the total daily dosage is 6 mg (30 kg * 0.2 mg/kg). This total daily dose should be divided into two doses, which means each dose will be 3 mg (6 mg / 2). Given that the available elixir concentration is 0.5 mg per 5 mL, to administer a 3 mg dose, the nurse would need 30 mL of the elixir (3 mg / 0.5 mg * 5 mL). Therefore, the nurse should administer 30 mL per dose.
