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:

  1. Convert pounds to kilograms:

    • 53 lb * 0.4536 kg/lb = 24 kg

  2. Calculate the daily dose in milligrams:

    • 10 mg/kg/day * 24 kg = 240 mg/day

  3. 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

  4. 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 A

Explanation

A) Take 15 mL 1 hr. after meals and at bedtime:

This instruction uses milliliters (mL), which is a metric unit of volume. The metric system is widely used in medical settings for its precision and universality, making milliliters a standard measurement for liquid medications.

B) Take 2 drops four times daily:

This instruction uses drops as the unit of measurement. Drops are not a metric unit; they are a more general unit often used in prescribing liquid medications, especially for eye or ear drops, but they lack the precision of metric measurements.

C) Take 0.5 oz 30 min before meals and at bedtime:

This instruction uses ounces (oz), which are part of the imperial system, not the metric system. Ounces are commonly used in everyday measurements in some countries but are not the preferred unit in medical settings where metric units are standard.

D) Take 1 tsp four times daily:

This instruction uses teaspoons (tsp), which are not metric units. Teaspoons are part of the household measurement system and are less precise compared to metric units, which can lead to variations in dosing.

Correct Answer is C

Explanation

A) mL: This abbreviation stands for milliliters, which is a metric unit of volume used to measure liquids. It is not a unit of weight, so it would not be identified as such when documenting in the medical record.

B) OZ: This abbreviation stands for ounces, which is a unit of weight used in the imperial system, not the metric system. It is important to distinguish between metric and imperial units for accurate documentation.

C) Mcg: This abbreviation stands for micrograms, which is a metric unit of weight. Micrograms are commonly used in the medical field to measure very small amounts of substances, such as medications. Recognizing this as a metric unit of weight is crucial for proper documentation.

D) Lb: This abbreviation stands for pounds, which is another unit of weight used in the imperial system. It is not a metric unit, so it should not be identified as such in the medical record.
