A nurse is preparing to administer 1,200,000 units of benzathine penicillin G IM. If the available benzathine penicillin G injection is 600,000 units/mL, how many mL should the nurse administer?

Answer and Explanation

The Correct Answer is ["2 "]

The nurse should administer 2 mL of benzathine penicillin G. Here’s the calculation: Step 1: The total dosage required is 1,200,000 units.

Step 2: Each mL of the injection contains 600,000 units of benzathine penicillin G.

Step 3: So, the volume to be administered is 1,200,000 units ÷ 600,000 units/mL = 2 mL.

Correct Answer is ["10 "]

Explanation

Step 1 is to calculate the volume of codeine to administer. Given that the available codeine oral solution is 10 mg/5 mL and the nurse needs to administer 20 mg, the calculation is as follows: 20 mg ÷ (10 mg/5 mL) = 10 mL4

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.
