Full Explanation
Step 1: Convert pounds to kilograms.
154 lb * (1 kg / 2.20462 lb) = 70 kg
Step 2: Calculate the total dose of gentamicin.
1 mg/kg * 70 kg = 70 mg
Step 3: Calculate the volume of gentamicin solution to administer.
70 mg / 40 mg/mL = 1.75 mL
Therefore, the nurse should administer 1.8 mL of gentamicin solution.

A nurse is preparing to administer morphine 0.2 mg/kg IM to a client who weighs 99 lb. Available is morphine injection 10 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
First, you need to convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram, so 99 lb / 2.2 = 45 kg. The dose of morphine is 0.2 mg/kg, so for a client who weighs 45 kg, the dose would be 0.2 mg/kg * 45 kg = 9 mg. To calculate the number of mL the nurse should administer, you need to divide the dose of morphine (9 mg) by the concentration of the morphine injection (10 mg/mL). This gives you 9 mg / (10 mg/mL) = 0.9 mL. When rounded to the nearest tenth, this remains
0.9 mL. So, the nurse should administer 0.9 mL of morphine injection.
A nurse is talking with the parent of a child who has asthma and a new prescription for albuterol inhalation aerosol 8.5 g, inhale 1 to 2 puffs orally every 4 to 6 hr as needed for asthma. The nurse interprets this medication as which of the following types of prescription?

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.
