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 ["5"]

Explanation

The nurse should instruct the client to take 5 mL of guaifenesin.

Here’s the calculation for your reference:

In the United States, 1 teaspoon (tsp) is approximately equivalent to 5 milliliters (mL).

So, if the client is instructed to take 1 tsp of guaifenesin, this would be:

VolumeinmL=1tsp×5mL/tsp=5mL

However, the question asks to round the answer to the nearest whole number.

So, the nurse should instruct the client to take 5 mL of guaifenesin.

Correct Answer is ["0.1"]

Explanation

The nurse should administer 0.1 mL of cyanocobalamin injection per dose.

Here's the breakdown:

Desired dose: 100 mcg

Concentration of available cyanocobalamin injection: 1,000 mcg/mL (note: we use 1,000 instead of 1.000 for easier calculation)

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

Volume to administer (rounded to nearest tenth) = Dose / Concentration

= 100 mcg / 1,000 mcg/mL

= 0.1 mL (rounded to nearest tenth)

Therefore, the nurse should administer 0.1 mL of the cyanocobalamin injection.
