A 29-pound preschooler is being treated for impetigo. The primary health care provider orders 40mg/kg/day of amoxicillin/clavulanate by mouth to be administered in divided doses every 12 hours. The elixir comes in a strength of 250 mg/5 mL. How many milliliters of amoxicillin/clavulanate should the nurse administer to this client per dose? (Round to the nearest tenth).

Answer and Explanation

The Correct Answer is ["5.3"]

1 kilogram equals 2.2 pounds.

The preschooler weighs 29 pounds, which is approximately 13.18 kilograms (29/2.2). The order is for 40 mg/kg/day

13.18 kg * 40 mg/kg = 527.2 mg/day.

Since the medication is to be administered every 12 hours, divide this daily dosage by 2 to get the per dose amount: 527.2 mg/day / 2 = 263.6 mg/dose.

Now, using the concentration of the elixir, which is 250 mg/5 mL, set up a proportion to find out how many milliliters are needed for the prescribed dose: 250 mg : 5 mL = 263.6 mg : X mL.

Solving for X gives us (263.6 mg * 5 mL) / 250 mg = 5.272 mL per dose.

Rounding to the nearest tenth, the nurse should administer 5.3 mL per dose.

A. Fluroquinolones B. Aminoglycosides C. Carbapenems D. Macrolides

Correct Answer is B

Explanation

A. Fluoroquinolones, such as ciprofloxacin and levofloxacin, do not have a known significant interaction with neuromuscular blockers. They can generally be used safely in patients receiving neuromuscular blockade.
B. Aminoglycosides (such as gentamicin, tobramycin, and amikacin) can potentiate the effects of neuromuscular blockers and may lead to increased neuromuscular blockade. This can result in respiratory depression or paralysis, making them contraindicated in patients receiving neuromuscular blockers.
C. Carbapenems (such as meropenem and imipenem) do not typically have a significant interaction with neuromuscular blockers. They can generally be used safely, although careful monitoring is always recommended in patients with neuromuscular blockade.
D. Macrolides (such as azithromycin and erythromycin) do not have a major contraindication with neuromuscular blockers. While they can affect certain neuromuscular transmission processes, they are not typically contraindicated in this context.
