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.

Correct Answer is ["2"]
Explanation
Step 1: We know that 1 mg of benztropine mesylate is equivalent to 1 mL. So, 2 mg will be equivalent to 2 mL.
Therefore, the nurse should administer 2 mL of benztropine mesylate.
Since 2 is a whole number, there is no need for rounding.
The leading zero does not apply in this case as the number is not less than 1.
There is also no trailing zero after the decimal point. So, the final answer is 2 mL.
Correct Answer is ["2"]
Explanation
Step 1: The dose to be administered is 18 mg of methylphenidate.
Step 2: The available methylphenidate oral solution has a concentration of10 mg/mL. This means that for every 1 mL of the solution, there are 10 mg of methylphenidate.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 18 mg ÷ 10 mg/mL = 1.8 mL.
Step 4: Round the answer to the nearest whole number. So, 1.8 mL rounds to2 mL.
The nurse should administer 2 mL of methylphenidate oral solution.
