A nurse is preparing to administer cefaclor 500 mg PO every 12 hours.

If the available cefaclor oral suspension is 250 mg/5 mL, how many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["10 "]

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.

Correct Answer is ["2 "]

Explanation

Step 1: Calculate the total daily dose of tobramycin. The doctor ordered 4 mg/kg/day, so 4 mg/kg/day × 60 kg = 240 mg/day.

Step 2: Divide the total daily dose into three equal doses, as it is to be given in three divided doses. So, 240 mg/day ÷ 3 = 80 mg/dose.

Step 3: Calculate the volume of tobramycin to administer per dose. The available tobramycin is 40 mg/mL, so 80 mg ÷ 40 mg/mL = 2 mL. The nurse should administer 2 mL of tobramycin per dose.

Correct Answer is ["14 "]

Explanation

The medication should be discarded 14 days after reconstitution. This is a standard guideline for most reconstituted medications to ensure potency and prevent bacterial growth.
