A nurse is reviewing the medication list of a client. Which of the following medication instructions should the nurse identify as being prescribed using a metric unit?
Take 1 tsp four times daily
Take 0.5 oz 30 min before meals and at bedtime.
Take 2 drops four times daily
Take 15 mL 1 hr after meals and at bedtime
The Correct Answer is D
This medication instruction is prescribed using a metric unit because mL (milliliters) is a unit of volume in the metric system. The other medication instructions are prescribed using non-metric units: tsp (teaspoon) and oz (ounce) are units of volume in the US customary system, while drops is a non-standard unit of volume.

Correct Answer is ["1"]
Explanation
The first step is to convert the client's weight from pounds (lb) to kilograms (kg).
146.7 lb ÷ 2.2 lb/kg = 66.68 kg
Next, the nurse should calculate the total dose of metronidazole the client needs.
7.5 mg/kg x 66.68 kg = 500.1 mg
Since the available tablets are 500 mg each, the nurse should administer:
500.1 mg ÷ 500 mg/tablet = 1 tablet (rounded to the nearest whole number)
Correct Answer is ["50"]
Explanation
If the daily dose is 200 mg and it is to be given in equally divided doses every 6 hours, then we need to
calculate the amount per dose:
200 mg ÷ 4 doses = 50 mg per dose
