A nurse is set to administer 3 mg of haloperidol lactate IM to a patient.

Given that the available haloperidol injection is 5 mg/mL, how many mL should the nurse administer?
Answer and Explanation

The Correct Answer is ["0.6"]

Step 1 is to calculate the volume of haloperidol to administer. Given that the available haloperidol injection is 5 mg/mL and the nurse needs to administer 3 mg, the calculation is as follows: 3 mg ÷ 5 mg/mL = 0.6 mL

Correct Answer is ["8 "]

Explanation

The nurse should administer 8 mL of phenytoin. Here’s the calculation: Step 1: The total dosage required is 200 mg.

Step 2: Each 5 mL of the oral suspension contains 125 mg of phenytoin.

Step 3: So, the volume to be administered is (200 mg ÷ 125 mg/5mL) = 8 mL.

Correct Answer is ["10 "]

Explanation

Step 1: We need to find out how many mL of cefaclor oral suspension the nurse should administer per dose.

Given:

The doctor’s order is 500 mg of cefaclor.

The available cefaclor oral suspension is 250 mg/5 mL.

Step 2: We set up a proportion to find out the volume of the oral suspension that contains 500 mg of cefaclor.

Let’s denote the volume we are looking for as X mL. So, we have:

250 mg : 5 mL = 500 mg : X mL

Step 3: We cross-multiply and solve for X. 250 mg × X mL = 500 mg × 5 mL

Step 4: We divide both sides by 250 mg. X mL = (500 mg × 5 mL) ÷ 250 mg

Step 5: We calculate X.

X = (500 mg × 5 mL) ÷ 250 mg = 10 mL

So, the nurse should administer 10 mL of the cefaclor oral suspension per dose.
