Mia and Emma are baking a giant cake for their class party! They have a recipe that calls for 1 kilogram (kg) of sugar, but their kitchen scale only measures in grams (g). Can you help them figure out the conversion factor from kilograms to grams?

• 1 kg = 10 g

• 1 kg = 100 g

• 1 kg = 1000 g

Elijah is helping out in the clinic and receives a medication order: "Give 500 mg acetaminophen." The available tablet strength is 250 mg per tablet. How many tablets should Elijah give to the patient?

• 1 tablet

• 2 tablets

• 3 tablets

• 4 tablets

• 2 tablets

• 3 tablets

• 4 tablets

• 5 tablets

Answer explanation

To find the number of tablets needed, convert 2 grams to milligrams: 2 grams = 2000 mg. Each tablet is 500 mg. Therefore, 2000 mg ÷ 500 mg/tablet = 4 tablets. Thus, the correct answer is 4 tablets.

Ava is helping her friend Luna with a nursing assignment. If a doctor orders 0.5 L of IV fluid for a patient, how many milliliters (mL) should Luna write down to be administered?

• 50 mL

• 100 mL

• 500 mL

• 1000 mL

Answer explanation

0.5 L is equivalent to 500 mL, as 1 L equals 1000 mL. Therefore, the correct amount of IV fluid to administer is 500 mL.

• 0.25 tablet

• 0.5 tablet

• 1 tablet

• 2 tablets

Answer explanation

To convert 250 mcg to mg, divide by 1000, resulting in 0.25 mg. Since each tablet is 0.5 mg, you need 0.25 mg, which is 0.5 tablet. Therefore, the correct answer is 0.5 tablet.

Maya is helping her little brother, who weighs 20 kg, get his medicine. The doctor says he needs 5 mg of the medication for every kg he weighs. Can you help Maya figure out the total dose in mg?

• 25 mg

• 50 mg

• 0.25 L

• 2.5 L

• 25 L

• 250 L
