Which technique is the proper method to administer otic drops to an adult client?

The question asks how many milligrams of the medication will be in 1 mL of D5W. To find this, we need to know the concentration of the medication in the solution.

Concentration is the amount of medication per unit volume of solution. We can use this formula:

Concentration = Mass / Volume

We know that 250 mg of the medication is diluted in 500 mL of D5W. So we can plug these values into the formula:

Concentration = 250 mg / 500 mL Simplifying, we get:

Concentration = 0.5 mg / mL

This means that there are 0.5 mg of the medication in every 1 mL of D5W. So the answer is

1. To check our answer, we can use another formula:

Mass = Concentration x Volume

If we want to find the mass of the medication in 1 mL of D5W, we can multiply the concentration by the volume:

Mass = 0.5 mg / mL x 1 mL Simplifying, we get:

Mass = 0.5 mg

This matches our answer.

The other choices are wrong because they do not use the correct formula or values. Here is why:

Choice A is wrong because it uses the inverse of the concentration (1 / 0.5) instead of the concentration (0.5).

Choice B is wrong because it uses the mass of the medication (250 mg) instead of the concentration (0.5 mg / mL).

Exercise has many health benefits, such as improving self-concept, decreasing resting pulse and blood pressure, and improving sleep quality.
