A nurse is preparing to administer dicloxacillin 6.25 mg/kg PO to a child who weighs 14 lb. Available is dicloxacillin 62.5 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3.2"]

To calculate the dosage of dicloxacillin to administer to the child, we need to follow these steps

Convert the child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 14 lb × 0.453592 = 6.35 kg

Determine the dose in mg:

Dosage required = 6.25 mg/kg

Dose = 6.25 mg/kg × 6.35 kg = 39.6875 mg

Determine how many mL of the medication to administer:

The concentration of dicloxacillin is 62.5 mg/5 mL

Using the formula:

Volume (mL)= Dose (mg)/Concentration (mg/mL)

Concentration (mg/mL) = 62.5 mg / 5 mL = 12.5 mg/mL

Volume (mL) = 39.6875 mg / 12.5 mg/mL = 3.175 mL

Round to the nearest tenth:

Volume to administer = 3.2 mL

The nurse should administer 3.2 mL of dicloxacillin.

Correct Answer is ["20"]

Explanation

The nurse should administer 20 mL of megestrol suspension.

Here's the calculation:

Desired dose: 800 mg

Concentration of available megestrol suspension: 40 mg/mL

To find the volume to administer, we can divide the desired dose by the concentration and round to the nearest whole number:

Volume to administer (rounded) = Dose / Concentration

= 800 mg / (40 mg/mL)

= 20 mL (rounded to nearest whole number)

Therefore, the nurse should administer 20 mL of the megestrol suspension.

Correct Answer is ["50"]

Explanation

Here's the correct breakdown:

Total daily dose: 200 mg

Frequency of administration: Every 6 hours (equally divided doses)

We divided the total daily dose by the number of doses per day to find the dose per administration:

Dose per administration = Total daily dose / Number of doses per day

= 200 mg / 4 doses/day

= 50 mg/dose
