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?
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 ["0.75 "]
Explanation
Step 1: Calculate the volume of meperidine injection to administer. The available meperidine injection is 100 mg/mL, so 75 mg ÷ 100 mg/mL = 0.75 mL. The nurse should administer 0.75 mL of meperidine injection.
