A nurse is preparing to administer benztropine mesylate 2 mg IM to a client who has schizophrenia and is experiencing an extrapyramidal reaction to antipsychotic medication.
Available is benztropine mesylate injection 1 mg/mL in 2 mL ampules. How many mL 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 ["2"]
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 ["2.8"]
Explanation
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: The total daily dose to be administered is300 mg of trazodone.
Step 2: The total daily dose is divided equally every 8 hours, so each dose is one third of the total daily dose. So, 300 mg ÷ 3 =100 mg per dose.
Step 3: The available trazodone tablets have a concentration of50 mg/tablet. This means that for every 1 tablet, there are 50 mg of trazodone.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 100 mg ÷ 50 mg/tablet =2 tablets.
The nurse should administer 2 tablets of trazodone in each dose.
