Full Explanation
To convert the client's weight from kilograms to pounds, you need to multiply the weight in kilograms by the conversion factor of 2.2 lb/kg. So, 91 kg * 2.2 lb/kg = 200.2 lb. When rounded to the nearest whole number, this becomes 200 lb.

A nurse is preparing to administer digoxin 7.5 mcg/kg/day PO daily to a school-age child who weighs 52 lb. Available is digoxin elixir 50 mcg/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.)
Full Explanation
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.538 mL per dose. Answer: 3.5
A nurse is preparing to administer gentamicin 36 mg IM to a school-age child. Available is gentamicin injection 40 mg/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.)
Full Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
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?
A. Take 1 tsp four times daily
B. Take 0.5 oz 30 min before meals and at bedtime.
C. Take 2 drops four times daily
D. Take 15 mL 1 hr after meals and at bedtime
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.
