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.

Correct Answer is ["1.7"]
Explanation
To calculate the IV pump setting, first determine the total micrograms of dopamine needed per minute for the newborn: 5 mcg/kg/min * 4.4 kg = 22 mcg/min. Next, convert the available dopamine concentration to micrograms: 200 mg * 1000 mcg/mg = 200,000 mcg. Now, calculate how many micrograms are in each mL of the solution: 200,000 mcg / 250 mL = 800 mcg/mL. Then, determine how many mL are needed per minute to deliver the required 22 mcg/min: 22 mcg/min / 800 mcg/mL = 0.0275 mL/min. Finally, convert this to an hourly rate: 0.0275 mL/min * 60 min/hr = 1.65 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 1.7 mL/hr.
Correct Answer is ["0.5"]
Explanation
To administer the correct dose of nalbuphine, which is 10 mg, when you have a concentration of 20 mg/mL, you need to calculate the volume to be administered. The formula to use is: (Dose ordered / Drug concentration) = Volume to administer. Plugging in the values: (10 mg / 20 mg/mL) = 0.5 mL.
