Answer 1

To calculate the amount of tobramycin (Tobrex) the nurse should administer to a preschooler weighing 20 kg, use the formula: Dose (ml) = Weight (kg) x Dose (mg/kg) / Concentration (mg/ml). Substituting the given values, the nurse should administer 1.25 ml of tobramycin per dose.

Step-by-step explanation:

To calculate the amount of tobramycin (Tobrex) the nurse should administer, we need to use the formula:

Dose (ml) = Weight (kg) x Dose (mg/kg) / Concentration (mg/ml)

Given that the preschooler weighs 20 kg, the dose is 2.5 mg/kg, and the concentration is 40 mg/ml, we can substitute these values into the formula:

Dose (ml) = 20 kg x 2.5 mg/kg / 40 mg/ml = 1.25 ml

The nurse should administer 1.25 ml of tobramycin per dose.
