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 ["2.5 "]

Explanation

The nurse should administer 2.5 tablets of prednisone. Here’s the calculation: Step 1: The total dosage required is 50 mg.

Step 2: Each tablet contains 20 mg of prednisone.

Step 3: So, the number of tablets required is 50 mg ÷ 20 mg/tablet = 2.5 tablets.

Correct Answer is C

Explanation

Choice A rationale

A vegetarian diet with cheese 2 to 3 times a day does not significantly increase the risk of kidney stones. While dairy products do contain calcium, which can contribute to stone formation, they also contain other compounds that help prevent stones. Furthermore, a vegetarian diet is typically high in fiber, which can also help prevent stone formation.

Choice B rationale

Jogging more frequently than usual daily routine does not increase the risk of kidney stones. In fact, regular exercise can help prevent kidney stones by keeping the urinary tract healthy and promoting regular urination.

Choice C rationale

Drinking several bottles of carbonated water daily can increase the risk of kidney stones. Carbonated water contains phosphoric acid, which can increase the acidity of the urine. This can promote the formation of kidney stones, especially in individuals who are already at risk.

Choice D rationale

Experiencing additional stress since adopting a child does not directly increase the risk of kidney stones. While stress can have many negative effects on health, there is no direct link between stress and kidney stone formation.
