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 ["50"]
Explanation
To calculate the IV pump setting, you would use the formula: Volume (mL) over Time (hr) = Rate (mL/hr). In this case, the total volume of the cefoxitin solution is 50 mL, and it needs to be administered over 1 hour. Therefore, the nurse should set the IV pump to deliver 50 mL/hr. When rounding to the nearest whole number, the rate remains 50 mL/hr.
Correct Answer is ["0.042"]
Explanation
To convert milligrams (mg) to grams (g), one must remember that 1 gram is equivalent to 1000 milligrams. Therefore, to find the equivalent in grams for 42 mg, the amount in milligrams should be divided by 1000. Doing the math, 42 mg divided by 1000 gives 0.042 grams. When rounding this to the nearest thousandth, it remains 0.042, as the fourth decimal place is not significant enough to round up the third decimal place. Hence, 42 mg is equivalent to 0.042 g.
