A nurse is preparing to administer ferrous sulfate 0.12 g PO to a client. How many mg should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["120"]
To convert grams to milligrams, you multiply the number of grams by 1,000. Therefore, to administer ferrous sulfate 0.12 g orally, you would give 120 mg, as 0.12 grams equals 120 milligrams. When rounding to the nearest whole number, it remains 120 mg.

Explanation
To convert grams to milligrams, the value in grams is multiplied by 1,000. Therefore, 0.65 grams of acetaminophen is equivalent to 650 milligrams. If one tablet contains 325 milligrams, the number of tablets needed would be 650 mg divided by 325 mg per tablet, which equals 2.
Correct Answer is ["133"]
Explanation
To calculate the infusion pump rate for a maintenance dose of magnesium sulfate, you need to determine how many milliliters per hour (mL/hr) will provide 4 grams (g) of magnesium sulfate per hour. Given that the pharmacy provides a 1-liter bag with 30 g of magnesium sulfate, this means there are 30,000 milligrams (mg) in 1,000 milliliters (mL) of solution. Since 1 g equals 1,000 mg, you need to administer 4,000 mg of magnesium sulfate per hour. To find the rate, divide the total amount of magnesium sulfate in the bag by the desired hourly dose: 30,000 mg divided by 4,000 mg per hour equals 7.5 hours of infusion time. Therefore, to administer the maintenance dose over one hour, you would set the infusion pump to 1,000 mL divided by 7.5 hours, which equals approximately 133.33 mL/hr = 133 mL/hr rounded off to the nearest whole number.
