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 ["1.1"]

Explanation

To calculate the dosage of dimercaprol for the adolescent, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The adolescent weighs 79 lb, which is approximately 35.91 kg (79 ÷ 2.2). The prescribed dose is 3 mg/kg, so the total dosage required is 107.73 mg (35.91 kg x 3 mg/kg). With the available dimercaprol injection of 100 mg/mL, the nurse should administer 1.1 mL (107.73 mg ÷ 100 mg/mL), rounding to the nearest tenth. Therefore, the nurse should administer 1.1 mL of dimercaprol injection.

Correct Answer is ["1"]

Explanation

To calculate the dosage of phenytoin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 38 lb, which is approximately 17.27 kg (38 lb / 2.2). Next, multiply the child's weight in kilograms by the dosage prescribed: 5 mg/kg/day. For this child, that would be 86.36 mg/day (17.27 kg * 5 mg/kg). Since the dose is divided every 12 hours, the amount per dose would be 43.18 mg (86.36 mg/day divided by 2). With phenytoin 50 mg chewable tablets available, the nurse would administer one tablet per dose.
