A nurse is preparing to administer clindamycin 10 mg/kg/day PO in three divided doses to a child who weighs 53 lb. Available is clindamycin oral solution 75 mg/5 mL. How many mL should the nurse administer per dose? (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 ["5.3"]

To calculate the correct dose of clindamycin, we need to follow these steps:

Convert pounds to kilograms:
- 53 lb * 0.4536 kg/lb = 24 kg
Calculate the daily dose in milligrams:
- 10 mg/kg/day * 24 kg = 240 mg/day
Calculate the dose per administration:
- Since the medication is divided into three doses, divide the daily dose by 3:
  - 240 mg/day / 3 = 80 mg/dose
Determine the volume needed from the available concentration:
- 80 mg * (5 mL / 75 mg) = 5.33 mL

Therefore, the nurse should administer 5.3 mL of clindamycin per dose.

Answer: 5.3 mL

Correct Answer is ["0.5"]

Explanation

Answer: 0.5 teaspoons (tsp) of amoxicillin suspension per dose.

Rationale:

1. Determine the volume per dose based on medication concentration and prescribed dosage:

Amoxicillin dosage per dose: 100 mg

Amoxicillin concentration: 200 mg/5 mL (milligrams per milliliters of suspension)

We can use the following formula to find the volume to administer:

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

Volume (mL) = 100 mg / 200 mg/5 mL

2. Convert milliliters (mL) to teaspoons (tsp):

1 teaspoon (tsp) is equivalent to 5 milliliters (mL) [This is a standard conversion rate]

Therefore, the volume in teaspoons (tsp) would be:

Volume (tsp) = Volume (mL) / Conversion factor (mL/tsp)

3. Round the answer to the nearest tenth:

Following these steps:

Volume (mL) = 100 mg / 200 mg/5 mL = 2.5 mL

Volume (tsp) = 2.5 mL / 5 mL/tsp = 0.5 tsp (rounded to one decimal place)

Therefore, the nurse should instruct the parent to administer 0.5 teaspoons (tsp) of amoxicillin suspension per dose.

Correct Answer is ["5","000","000"]

Explanation

The nurse should recognize that the 5 g amount is equal to 5,000,000 mcg (rounded to the nearest whole number).

Here's the conversion process:

Conversion factor: There are 1,000,000 mcg in 1 gram (g).

Calculation:

Amount in mcg = Amount in g x Conversion factor (mcg/g)

Amount in mcg = 5 g x 1,000,000 mcg/g

Rounding the answer:

Amount in mcg = 5,000,000 mcg (rounded to nearest whole number)

Therefore, the 5 g amount is equivalent to 5,000,000 mcg.
