The nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled "125 mg per 2 mL." How many mL of medication should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)

Answer and Explanation

The Correct Answer is ["0.64 mL"]

The correct answer is 0.64 mL. To find the answer, we can use the following formula:

(mL to be administered) = (mg prescribed) / (mg per mL)

Substituting the given values, we get:

(mL to be administered) = (40) / (125 / 2)

Simplifying, we get:

(mL to be administered) = (40) x (2 / 125)

(mL to be administered) = 0.64

Therefore, the nurse should administer 0.64 mL of methylprednisolone IV.

Correct Answer is ["75"]

Explanation

To find the answer, we can use the following steps:

- Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL

- Multiply the dose in mg per administration by the number of administrations per day

- Round the result to the nearest whole number

Using these steps, we get:

- (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg

- (total daily dose in mg) = (37.5) x (2) = 75 mg

- (rounded total daily dose in mg) = 75 mg

Therefore, the client receives 75 mg of diphenhydramine per day.

Correct Answer is ["1 mL"]

Explanation

First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.

Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:

Amount of solution= amount of water + amount of warfarin

Substituting the given values, we get:

Amount of solution = 2.7 + 5 =7.7 mL

Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:

mL of solution = mg of warfarin/ concentration of warfarin

Substituting the given values, we get:

mL of solution = 2/2 = 1 mL

Therefore, the nurse should administer 1 mL of solution to the patient.
