A nurse is preparing to administer haloperidol decanoate 75 mg IM to a client who has schizophrenia. Available is haloperidol decanoate injection 50 mg/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.)

Answer and Explanation

The Correct Answer is ["1.5"]

Step 1: The dose to be administered is75 mg of haloperidol decanoate.

Step 2: The available haloperidol decanoate injection has a concentration of50 mg/mL. This means that for every 1 mL of the solution, there are 50 mg of haloperidol decanoate.

Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 75 mg ÷ 50 mg/mL = 1.5 mL.

The nurse should administer 1.5 mL of haloperidol decanoate injection.

Correct Answer is ["0.5"]

Explanation

The nurse needs to administer 50 mg of amitriptyline and each tablet contains 100 mg.

Step 1 is: Calculate the number of tablets by dividing the required dose by the dose available per tablet.

So, 50 mg (required dose) ÷ 100 mg/tablet (dose per tablet)

Step 2 is: Perform the division.

This gives us 0.5 tablets.

Step 3 is: Round the answer to the nearest tenth as instructed.

So, 0.5 rounded to the nearest tenth is 0.5.

Correct Answer is ["2.3"]

Explanation

Step 1: The dose to be administered is300 mg of phenobarbital sodium.

Step 2: The available phenobarbital sodium injection has a concentration of130 mg/mL. This means that for every 1 mL of the solution, there are 130 mg of phenobarbital sodium.

Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 300 mg ÷ 130 mg/mL = 2.307692307692308 mL.

Step 4: Round the answer to the nearest tenth. So, 2.307692307692308 mL rounds to2.3 mL.

The nurse should administer 2.3 mL of phenobarbital sodium injection.
