A nurse is preparing to administer aripiprazole 9 mg IM to a client. Available is aripiprazole injection 9.75 mg/3 mL. How many mL 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 ["2.8"]
Step 1: The dose to be administered is9 mg of aripiprazole.
Step 2: The available aripiprazole injection has a concentration of9.75 mg/3 mL. This means that for every 3 mL of the solution, there are 9.75 mg of aripiprazole.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 9 mg ÷ (9.75 mg/3 mL) = 2.769230769230769 mL.
Step 4: Round the answer to the nearest tenth. So, 2.769230769230769 mL rounds to2.8 mL.
The nurse should administer 2.8 mL of aripiprazole injection.

- Total perphenazine to be administered: 200 mg
- The medication is to be divided into four equal doses
- Available perphenazine oral solution: 16 mg/mL
Step 1: Calculate the amount of perphenazine per dose
200 mg ÷ 4 = 50 mg/dose
Step 2: Calculate the volume of the oral solution per dose
(50 mg/dose) ÷ (16 mg/mL) = 3.125 mL/dose
Rounding to the nearest tenth, the nurse should administer 3.1 mL
Correct Answer is ["1800"]
Explanation
-Step 1: Define the conversion factor from grams to milligrams. We know that 1 g = 1000 mg.
-Step 2: Multiply 1.8 g by the conversion factor (1000 mg/g). The calculation is 1.8 g × 1000 mg/g = 1800 mg.
-Step 3: Round the result to the nearest whole number. The rounded result is 1800 mg.
